Debugging Java and PL/SQL Together

Shay Shmeltzer
Director of Product Management - Oracle

A couple of people pinged me to ask if it was possible to do a "Step-into" from a Java class into a PL/SQL stored procedure while debugging.

The answer is yes if you are using JDeveloper.

The trick is to use two debug sessions - one to remote debug the PL/SQL and the other to debug the Java file.

Here is a little demo and explanation of the setup to get this working.

(you might want to press F11 while watching to get see the full screen).

    Toad version 9 also allows this, all with a single debug session.

    Nice demo. This was possible since JDev 9.0.2. I could do it with only one debugging session, but need to find the time to write this up...

    Nice to know that TOAD can do it too - but the difference is that JDeveloper is free and is also a full blown Java development environment :-)

    Hi everyone,
    I am using Eclipse, I tried to follow similar steps like in the demo to try to make remote debugging work, but I get an "Invalid statement error" when the procedure that sets DBMS_DEBUG_JDWP.CONNECT_TCP is called.
    How can I make remote debugging work in Eclipse, are there any other references to this problem?

    Hi, The demo link posted is not working.

    Can you please correct it, as I am not able to debug pl/sql from java using jdeveloper. I am able to debug the java part , but the debugger is not entering the pl/sql part. I am using jDeveloper studio10.1.3.5

    Appreciate your reply on this.

    thank you

    The URL which you posted shows how to debug the code from PL/SQL and from java.


    Please help me how to debug pl/sql when a java program invokes pl/sql procedure.
