Re: Oracle Web Architecture Question, please help...

You need Oracle Jinitiator (a replacement JRE) which you can get from www.oracle.com for free.

DO NOT try and run Web Forms in tha JRE's supplied with either NS or IE they are unsupported and are bug ridden.

With Jinitiator installed both browsers will work fine - guaranteed !

The front layer is just any web browser with a Java1.1 (or newer) JVM.

The Middle layer is the compination of an HTTP (web) server and an oracle EXE
called the "Forms server listner" under the old Oracle Web Application Server
3. Under version 4, Renamed "Oracle Application Server"(minus the "web") the
forms server listner is now just part of OAS (it used to stand alone).

The back layer is any ODBC compliant database.  Realistically speaking, the
back end is a SQL*Net (or Net8) connection to an Oracle database.

 I heard that the

Yes.  Although I can't seem to get it to work with IE (and Netscape needs to
be 4.06 or better)(According to Microsoft, IE4.01 is JVM1.1 compliant).  If
you look arround there are a lot of posts from people who can't use both
browsers.

What platform Oracle web server is (NT or UNIX?)?
Both, check www.oracle.com for a platforms supported list.

How about the Oracle database version?

Nope.  7.3.2 works fine and I assume that any SQL*Net V2 compliant database
will work (SQL*Net V2 came out with Oracle7.1)

No problem, Jimmy.  I put some Oracle forms on the web this week, it didn't
take much effort.  They work really slick, except that I can't seem to get
IE4 to work.

A couple of pointers:
  1. If you just install the Forms Server, the install process doesn't install
  the EWT java classes, FORMS50_PATH, and TK25_ICON registry keys that you'll
  need.  So install form builder too even if you won't use it.

  2. In the %ORACLE_HOME%/tools/devdem20/guide21/ directory there is a file
called d2k_web.htm.  It's filled with all kinds of caveats (almost entirely
about OS specific call-outs).  Give it a read.
