Hello,

I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:\java\jdk\bin\java) using database package with Java stored procedure.

Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax: c:\java\jdk\bin\java -cp and here arae my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getingg error: C:\java\jdk\bin\java not found (Note that lookup with PATH isn't done due to the oracle executable being setuid.)

I have no idea what can I do more, every advice would be very helpful.

Let me disagree with you. I searched some web sites related to this topic and I found that this is quite often activity, on Windows and Linux OS.

Maybe I should create oracle directory pointing onto my path with java ?

And an Oracle directory resides on the server only.

Do NOT just explain what you did and got, SHOW US.

Use SQL*Plus and copy and paste your session, the WHOLE session.

Before, Please read OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version, with 4 decimals.

Regards
Michel

I don't know what you have.
I don't know what you do.
I don't know what you see.
It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.

You seem to be mixing up a few concepts.

* You can call anything on the server from inside a PL/SQL procedure. PL/SQL runs on the server, there is no way to run something on the client. (unless you can run "remote commands" via SSH or some other remote access on the client from the server)

* You could call a OS process on the client from the SQL script run by SQL*Plus, but NOT from inside a PL/SQL process that runs ON THE SERVER.

OK before I paste code maybe I will try to write more clearly what I want to do.

Generally problem is related with batches. I was migrating some aplication based on Oracle Forms 6i to Oracle Forms 11g (also database form 9i to 11g). I also inherited some strange manner of executing batch processes related to migrated application. Shortly it wad starting from commandline and some forms where directly invoked.

After migration to 11g everything works on applet in browser. And batch process was changed to that started from SQLPlus.
SqlPlus run database package which includes java stored procedure. The owner of the migrated application provides some jars, one of them was load into database and other are invoked from java stored procedure, but they are stored on client machine.

Hmm, I am totally frightened that you are right. I make mistake and it will probably be necessary to use ssh to connect to my machine from datatabse server.

It might be worth investigating whether you can move the batch process to the server entirely. Since Forms6i was client/server based there might have been technical reasons to have the batch run on the client, but with Forms 11g it makes more sense to have everything running on the server.
