Java Web Start Now Available for EBS 12.1 and 12.2

Steven Chan - Mon, 2017-04-24 12:20

Java Web Start (JWS) is now available for Oracle E-Business Suite 12.1 and 12.2:

What is Java Web Start?

Java Web Start launches E-Business Suite Java-based functionality as Java Web Start applications instead of as applets.  Java Web Start is part of the Java Runtime Environment (JRE).

Does EBS use Java on desktop clients?

Yes.  The E-Business Suite requires Oracle Forms.  Oracle Forms requires Java. 

Other EBS products also have functionality that require Java.

What is the new approach with Java Web Start?

It's not technically "new" (it is a mature Java technology originally released in 2004), but we're using it for the first time with the E-Business Suite.  This approach launches EBS Forms-based screens and other functionality as Java Web Start applications instead of as applets.

What prerequisites are needed for Java Web Start?

 Oracle E-Business Suite Release  Minimum JRE Release  12.2  JRE 8 Update 121 b33  12.1.3  JRE 8 Update 121 b33

A small number of server-side patches for Forms and EBS are needed. See:

Why is this important?

Until now, E-Business Suite's Java-based content required a browser that supports Netscape Plug-in Application Programming Interface (NPAPI) plug-ins.

Some browsers are phasing out NPAPI plug-in support.  Some browsers were released without NPAPI plug-in support.  This prevents the Java plug-in from working.

With the release of Java Web Start, E-Business Suite 12.1 and 12.2 users can launch Java-based content (e.g. Oracle Forms) from browsers that do not support Java plug-ins via NPAPI.  Java Web Start in EBS works with:

  • Microsoft Internet Explorer
  • Microsoft Edge
  • Firefox Rapid Release (32-bit and 64-bit)
  • Firefox Extended Support Release (32-bit and 64-bit)
  • Google Chrome

How does the technology architecture change?

Java Web Start changes the way that Java runs on end-users' computers but this technical change is generally invisible to end-users.

Java Web Start applications are launched from browsers using the Java Network Launching Protocol (JNLP).

Will the end-user's experience change?

Generally not. We have worked hard to ensure that your end-users' experience with Java Web Start applications is as similar as possible to applets via the Java browser plugin.  The differences between the Java Plug-in and Java Web Start are expected to be almost-invisible to end-users.

Will E-Business Suite still require Java in the future?

Yes.  It is expected that our ongoing use of Oracle Forms for high-volume professional users of the E-Business Suite means that EBS will continue to require Java.  We replicate, simplify, or migrate selected Forms-based flows to OA Framework-based (i.e. web-based HTML) equivalents with every EBS update, but Oracle Forms is expected to continue to be part of the E-Business Suite technology stack for the foreseeable future. 

Does the E-Business Suite have other Java applet dependencies?

Yes.  In addition to Oracle Forms, various E-Business Suite products have functionality that runs as Java applets.  These Java applets require browsers that offer plugin support.  These products include applets:

  • Oracle General Ledger (GL): Account Hierarchy Manager
  • Oracle Customers Online (IMC): Party Relationships
  • Oracle Call Center Technology (CCT)
  • Oracle Sourcing (PON): Auction Monitor
  • Oracle Installed Base (CSI): Visualizer
  • Oracle Process Manufacturing (OPM): Recipe Designer
  • Oracle Advanced Supply Chain Planning (MSC): Plan Editor (PS/SNO)
  • Workflow (WF): Status Diagram, Notification Signing with Digital Signatures
  • Scripting (IES): Script Author

What is the roadmap for browser support for plug-ins?

Plug-in support has various names, including:

This article will simply use the term "plug-in support," which refers to all of the different types listed above.

Some browsers are phasing out plug-in support. Some browsers were never released with plug-in support.

Some organizations may wish to use browsers that do not offer plugin support.  The Java Web Start approach works with all browsers, regardless of whether they have plugin support. 

What is the roadmap for Java's support for plug-ins?

The Java team recently published their plans
for removing the Java browser plugin in a future version of Java. The announcement states (highlighted for emphasis):

Oracle plans to deprecate the Java browser plugin in JDK 9. This technology will be removed from the Oracle JDK and JRE in a future Java SE release.

What does "deprecate" mean?

In this context, "deprecate" means there will still be a Java Plug-in in JRE 9.

In other words, JRE 9 will include the Java Browser Plug-in and Java Web Start.  Users will still be able to run Java-based applications using the Java Plug-in and Java Web Start in JRE 9.

What does this mean for E-Business Suite users running the Java Plug-in with JRE 9?

The release of Java 9 is not expected to affect E-Business Suite users.

JRE 9 is expected to continue to work with the E-Business Suite in browsers that support the Java Browser Plug-in via the NPAPI protocol.

JRE 9 is expected to work with the E-Business Suite in browsers that support Java Web Start.

What browsers are expected to support the JRE 9 plug-in?

Internet Explorer, Firefox ESR 32-bit, and Safari are expected continue to support NPAPI -- and, therefore, Java and Forms. 

Firefox Rapid Release, Firefox ESR 64-bit, Google Chrome, and Microsoft Edge do not support NPAPI, so Java-based apps cannot run in those browsers using the Java Plug-in.  EBS users can run Java-based content using Java Web Start with JRE 9.

What are the timelines for browsers' plugin support?

Individual browser vendors have been updating their plans regularly.  Here's a snapshot of what some browser vendors have stated as of today:

Microsoft Internet Explorer (IE)

Microsoft has indicated that they intend to continue to offer plug-in support in IE.

Microsoft Edge

Microsoft Edge was released in Windows 10 without Browser Helper Object (BHO, aka. plugin) support.  Microsoft has no plans to add plugin support to Edge.

Mozilla Firefox Extended Support Release (ESR)

Mozilla indicated in early 2016 that Firefox ESR 52 32-bit will be the last version to offer NPAPI (and JRE) support.  Firefox ESR 52 32-bit was released in March 2017 and will be supported until May 2018. 

Mozilla removed NPAPI support from Firefox ESR 52 64-bit in March 2017.  

Mozilla Firefox Rapid Release

Mozilla removed NPAPI support from the Firefox 52 Rapid Release version in March 2017. 

Apple Safari for macOS

Safari offers Internet plug-in support for macOS users.  Apple has not made any statements about deprecating plugin support for macOS users.

Google Chrome for Windows

Chrome offered support for plugins until version 45, released in September 2015.  They removed NPAPI support in later Chrome releases.

Will I need to change browsers for EBS 12.1 or 12.2?

Not generally, but it depends on your choice of browsers and whether you wish to use Java Plug-in or Java Web Start.

Here's the compatibility matrix for EBS 12.1 and 12.2 certified combinations:

   Java Plug-In  Java Web Start  Microsoft Internet Explorer  Yes  Yes  Microsoft Edge    Yes  Firefox Rapid Release 32-bit    See Note 1  Firefox Rapid Release 64-bit    See Note 1  Firefox Extended Support Release 32-bit  Yes  Yes  Firefox Extended Support Release 64-bit    Yes  Google Chrome    Yes  Safari on macOS  Yes  See Note 2

Note 1: Expected to work but not tested.

New personal versions of Firefox on the Rapid Release channel are released roughly every six weeks.  It is impractical for us to certify these new personal Rapid Release versions of Firefox with the Oracle E-Business Suite because a given Firefox release is generally obsolete by the time we complete the certification.

From Firefox 10 and onwards, Oracle E-Business Suite is certified only with selected Firefox Extended Support Release versions. Oracle has no current plans to certify new Firefox personal releases on the Rapid Release channel with the E-Business Suite.

Note 2: Not certified.

Apple changed the Gatekeeper permissions in macOS Sierra 10.12.  These changes prevent JNLP execution, making the Java Web Start user experience very challenging.  We are investigating options right now. 

Will Oracle release its own browser for the E-Business Suite?

No.  Long-time Oracle users may remember the Oracle PowerBrowser. The industry has since moved away from software that requires proprietary browsers.  We have no plans to release a browser specifically for E-Business Suite users. 

Will this work on Android or iOS?

No. Neither of these operating systems are compatible with Java. 

E-Business Suite users who need to run Oracle Forms-based content or other Java-based functionality should use Windows or macOS.

Will Java Web Start be mandatory?

Not immediately. It is expected that the use of Java Web Start will be optional at least up to, and including, Java 9, which may be the last Java release to include the JRE browser plugin. 

Will Java Web Start coexist with JRE?

Yes.  You can have a mixed environment where some end-users launch Java Web Start applications, while others use applets via the Java plug-in.  This mixed group of end-users can connect to the same E-Business Suite environment.

EBS system administrators have full server-side control over these choices.

Will this affect EBS customizations?

Maybe. It depends upon which of the following apply to your environment:

  • Scenario 1You have modified standard EBS screens running in Forms: 
    No actions needed. These customizations are expected to work with Java Web Start without any additional changes.
  • Scenario 2You have built custom Java applets of your own to extend the E-Business Suite:  These will continue to run with the Java plug-in, but you may wish to update those applets to use Java Web Start.
  • Scenario 3You have third-party extensions or products that depend upon the Java plug-in:
    These will continue to run with the Java plug-in but you may wish to contact your third-party vendor for details about their plans for Java Web Start.

Are there any additional licensing costs?

No. Java Web Start is included with EBS licenses and does not introduce any new licensing costs.

Oracle E-Business Suite 12.2 Web Services Security for Oracle Supplier Network

This is the ninth posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

The most common use of web services with the Oracle E-Business Suite is the Oracle Suppler Network (OSN). Do not confuse OSN with the Oracle Social Network (also referred to as OSN) or when configuring OSN, do not confuse the Oracle Transport Agent (OXTA) web services with Oracle Training Administration (OTA) web services.

To use OSN, you must configure the both the url_fw.conf and url_fw_ws.conf file to open traffic for the XML Gateway to consume OXTA web services. The OSN documentation in places confuses OTXA and OTA.  The risk is that in the url_fw_ws.conf there are services for both the Oracle Training Administration (OTA) module as well as for the OXTA. Unless both are being used, be careful to open only the correct services.

It should also be noted that while OSN uses web services, as of 12.2.5, OSN’s web services are NOT shown as deployed in the ISG repository.  This is because OSN’s functionality is built into the Oracle E-Business Suite’s core functionality.

It is very important to note that while using OSN with trading partners over the Internet requires opening the E-Business Suite to the Internet. Unfortunately, it is not clearly stated that a WAF, ideally the API Gateway, should be used to protect OSN. Even if OSN is the only web service being used, a WAF is still required to guard the attack surface.

Lastly, the passwords used for the various OSN accounts (defined within the OSN GUI forms) need to be complex and regularly rotated. Many clients forget about these accounts.

Guide to PeopleSoft Logging and Auditing - Revised Whitepaper

After discussions at Collaborate2017 with several PeopleSoft architects we have revised our Guide to PeopleSoft Auditing. The key change is the recommendation NOT to use PeopleSoft’s native database auditing and to instead use Oracle Fine Grained Auditing (FGA). FGA comes free with the Enterprise Edition of the Oracle RDBMS and, not only is it easier to implement, FGA does not have the performance impact of PeopleSoft’s native auditing.

If you have questions, please contact us at info@integrigy.com

Oracle E-Business Suite 12.2 Mobile and Web Services Security Requires Web Application Firewall (WAF)

This is the eighth posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

Web Application Firewalls (WAFs) cannot replace the URL Firewall, nor can the URL Firewall replace WAFs.  The URL Firewall provides the critical function of only allowing those forms and web services that have been both hardened by Oracle and flagged by the client as being used – all other requests are blocked by the default-deny rules. The URL Firewall does not protect against common web attack techniques such as those below – this what WAFs protect against:

  • Denial of Service (DoS)
    • Flooding, recursive & oversized payloads
  • Injection & Malicious Code
    • XXC, SQLi, logic bombs, malformed content
  • Confidentiality and Integrigy
    • Parameter tampering, schema poisoning
  • Reconnaissance Attacks
    • Scanning and registry disclosure
  • Privilege Escalation Attacks
    • Race condition, format string, buffer overflow

Additional protection is required to secure Internet facing Oracle E-Business Suite web services. Third party WAFs can certainly be deployed, but Oracle Corporation’s API Gateway offers a compelling advantage for Oracle E-Business Suite clients. The API Gateway is a separate license option and is placed in front of the SOA Server (also a separate license option) to defend against the common web attack techniques specific to web services as identified above.

Oracle E-Business Suite 12.2 Web Services Security: Authentication and Authorization

This is the seventh posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

Once traffic is accepted and passed by the URL Firewall, WebLogic initiates the standard Oracle E-Business Suite authentication and authorization procedures. Web services are authenticated and authorized no differently than for end-users.

Authorization rules for web services are relatively easy to configure in that all web services are defined as functions. The Oracle E-Business Suite's function security scheme and rules engine apply the same to GUI forms as for web services. In other words, the table APPLSYS.FND_FORM_FUNCTIONS defines all the forms that users use as well as defines all web services deployed. Menus then are built referencing these functions and Oracle E-Business Suite user accounts (APPLSYS.FND_USER) are given responsibilities with the menus of functions. These user accounts can be staff members or can be generic accounts (e.g. to support specific web services). Ensuring that appropriate users and responsibilities can call and use specific web services is the same critical step as ensuring that only appropriate users can use specific forms.

There are two authentication options for web services, local FND_USER passwords and tokens. Tokens can be SAML send vouchers/E-Business Suite Session Ids). Whichever is used, ensure that accounts are not inappropriately over privileged and the passwords and tokens not widely known and/or shared.

Oracle Listener Security New ORACLE 12.2 Firewall Feature

Service-Level ALCs is a new feature of the 12.2 Listener that allows every database service to have its own ACL. The ACL must be based on IP addresses and this feature allows multitenant pluggable databases (PDBs) to each have an ACL enforced by the Listener. This is because each PDB is a unique service registered in the Listener.

To implement this feature a new parameter FIREWALL must be used and has the following options:

  • (FIREWALL=ON) - This enables strict ACL validation (whitelist-based approach) of all connections based on the ACLs. If no ACLs are configured for a service, all connections are rejected.
  • FIREWALL is not set (defined for service) – This is a mixed mode. If an ACL is configured for a service, it will be enforced. If no ACL is defined, all connections will be accepted.
  • (FIREWALL=OFF) No validation (No ACLs enforced) and all connections are accepted

David Haimes - Fri, 2017-03-31 19:22

This year will be my sixth year at Collaborate, according to my recollection I first presented there in 2011 and have only missed one year (2013) since then.  It’s going to be a shorter visit than usual, so apologies if I don’t get to connect with you or attend your session.  Here is where you can find me…

Monday

Two of the most knowledgeable speakers you will see are speaking at the same time, there should be a law against it.  I might shuttle between the two, because I don’t want to miss either presentations

2:45 PM– Jasmine H – Mohan Iyer

How do I know where to use – FAH, FAHRCS or SLA?

2: 45 – South Seas I – Thomas Simkiss

Tips and Tricks – Get the most out of Financial Reporting in the Oracle Cloud

4:15 Jasmine H – General Ledger SIG – Always a good knowledgeable crowd.

Tuesday

7am – Morning run

Join myself, Peter Care (@FXLoader) and hopefully quite a few others for as many laps of the Mandalay bay pool complex as you feel up to.  This is now officially an annual tradition, we ought to get OAUG to put it in the agenda.  Best way to blow away the cobwebs and energize yourself for the day ahead.

8:30am – Keynote –  Glenn Finch, IBM

I have been quietly spending a lot of time around blockchain for some time now, so this got my attention.  If you don’t know about blockchain you should, I’m happy to talk about it at any opportunity.  This excerpt from the description should give you an idea how big it really can be

emerging technologies such as Blockchain, Cognitive and Quantum Computing will do more than change our businesses. They will transform industries and create their own ecosystems

Expect to hear more from me about blockchain as the year goes on.

1:30pm – I’m speaking about @FAHRCS

Come see my session – 1:30 PM–2:30 PM South Seas G

How E-Business Suite Customers have achieved modern reporting in the cloud

2:15pm – Fintech Design Jam

I’m a mentor for this two hour Design Jam run by the Applications UX Innovation Events team.  If you have not registered not sure if there is time now, but if you already are I will see you there.  Our goal is to help the teams tell a story about how they would use Fintech in their work, helping them hone in on a manageable 3 minute story showcasing their design.

Oracle E-Business Suite Mobile and Web Services Security Explained - Starting with URL Firewall

This is the sixth posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

How are web services secured in Oracle 12.2? To start at the beginning, the “front door” of the Oracle E-Business Suite is its web server, the Apache server deployed within the WebLogic server that is installed with release 12.2. To secure an Apache web server largely requires setting various configurations in the Apache configuration file (httpd.conf). For the Oracle E-Business Suite, these critical settings are maintained by Oracle through the AutoConfig utility. 

URL Firewall

The most important setting for Internet-facing clients is the include for the Oracle E-Business Suite’s URL Firewall. When the URL Firewall is included in the httpd.conf, every web request is passed through the URL Firewall, both for forms and for web services. The URL Firewall is non-discretionary and mandatory requirement when the Oracle E-Business Suite is deployed on the Internet.

HTTPD.CONF include for the URL Firewall

The URL Firewall is a template maintained by Oracle that whitelists those forms (e.g. JSP pages) that Oracle Corporation has hardened for use on the Internet. If the JSP is not listed “whitelisted” in the file url_fw.conf it should NOT be used on the Internet. Be sure to use the latest version of the template as Oracle periodically updates the template.

In the template, Oracle comments out all lines which effectively “Denies All.” To use the url_fw.conf, DBAs at each client site need to manually uncomment (“open”) specific JSP pages appropriate to their site. This “opening” by the DBAs must be carefully done and routinely reviewed.

The mechanics of when the url_fw.conf is called or not is determined by the Node's trust level. Most large Oracle E-Business Suite implementations have multiple web servers (referred to as nodes). To deploy the Oracle E-Business Suite on the Internet, one ore more nodes are deployed in a DMZ. If the node making the request of the Apache web server is flagged as an "Internal" web node, the url_fw.conf is skipped. If however the Node's trust level is flagged as "External" because the node is deployed in the DMZ, the url_fw.conf is called.

When called, the url_fw.conf applies regular expressions to the web request to determine if the request is BOTH exists in the whitelist and has been uncommented “opened” by the DBAs. If no match is found, a default-deny result is returned. In security terms, this means all requests are rejected unless explicitly allowed. If a match is found, the web request continues and the WebLogic server will then proceed with authentication and authorization tasks.

Example of URL FW line uncommented

Enabling and configuring the URL Firewall is the first step in securing web services. Unfortunately, Oracle buries the documentation for the URL Firewall in Appendix E of DMZ configuration guide – see the reference section of this paper for more information on the documentation.

To secure web services, it gets more complicated in that a second whitelist is appended to the first. To secure Oracle E-Business Suite web services, the url_fw.conf calls the url_fw_ws.conf. Similar to the configuration of the url_fw.conf, the documentation is buried deep in Appendix E of the DMZ configuration guide.

Different than the url_fw.conf which is supplied as a static listing of JSP pages, a utility (txkGenWebServiceUrlFwConf.pl) is run to generate the file url_fw_ws.conf. After being generated, DBAs similarly need to manually uncomment only those lines for the web services being used. If a web service is not found to be whitelisted, a default-deny rule will be applied; all web services commented out will be denied.

Example of URL FW WS.conf

Errors in selecting a Node’s trust level and configuring either the url_fw.conf and/or the url_fw_ws.conf have serious security consequences and should be routinely reviewed as part of on-going security audits.

Web services can be publically deployed without using the URL Firewall. For example, clients can if they so choose route Internet traffic directly to the E-Business Suite without setting up an External node. Integrigy Corporation highly recommends against doing this. Integrigy Corporation highly recommends always using the URL Firewall when deployed on the Internet, both for forms and for web services.

URL Firewall called by Node Trust Level

httpd.conf calls the URL Firewall

Cloning EBS 12.1.3 Environments Integrated with Oracle Access Manager

Steven Chan - Tue, 2017-03-28 02:05

We have documented procedures for cloning EBS 12.1.3 environments.  We also have documented procedures for integrating EBS 12.1.3 environments with Oracle Access Manager
(OAM) and Oracle Internet Directory (OID).  The next logical question
would be: do we have documented procedures for cloning EBS 12.1.3
environments that have been integrated with OAM and OID?

Yes, we have published this here:

EBS OAM architecture

This Note provides a certified process and detailed steps to:

  • Clone EBS using Rapid Clone
  • Deregister the cloned EBS instance from OAM and remove AccessGate
  • Remove OID from the cloned EBS instance
  • Integrate the cloned EBS instance with OID
  • Integrate the cloned EBS instance with OAM
  • Reconfigure SSL
