Remte JSP debugging for standalong OC4J 10.3.x not working

Question

Follow the next steps:
1. Copying the ojc.jar, jdev-rt.jar and jdev-remote.jar to the OC4J_HOME/lib
directory
2. Add the next lines to the application.xml file
< !-- Remote Debug settings -->
< library path="../../../lib/jdev-rt.jar" />
< library path="../../../lib/ojc.jar" />
< library path="../../../lib/ojmisc.jar" />
3. Change the global-web-application.xml in a text editor.
From the following section:
< orion-web-app
jsp-cache-directory="./persistence"
servlet-webdir="/servlet"
development="false"
>
Change development="false" to development="true" to enable servlet
debugging.
4. In the global-web-application.xml file, modify the jsp servlet tags to be:
< servlet>
< servlet-name>jsp< /servlet-name>
< servlet-class>oracle.jsp.runtimev2.JspServlet< /servlet-class>
< init-param>
< param-name>debug_mode< /param-name>
< param-value>true< /param-value>
< /init-param>
< init-param>
< param-name>developer_mode< /param-name>
< param-value>true< /param-value>
< /init-param>
< init-param>
< param-name>encode_to_java< /param-name>
< param-value>true< /param-value>
< /init-param>
< init-param>
< param-name>emit_debuginfo< /param-name>
< param-value>true< /param-value>
< /init-param>
< init-param>
< param-name>jspjavacompiler< /param-name>
< param-value>oracle.jdevimpl.jsp.JspOjcCompiler< /param-value>
< /init-param>
< load-on-startup>0< /load-on-startup>
< /servlet>
5. Start the oc4j using the next command:
java -hotspot -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000 -jar oc4j.jar
6. Deploy the application
7. Select the Remote Debugging and Profiling option in the Run Configuration
for the project with the jsp to debug.
8. In the Debugger/Remote section of the run Configuration set the host, port
and timeout to the correct ones (name of the computer where you are running
the application).
When trying to run the jsp you are going to get the error:
STACK ERROR:

Reproduced the problem with the next products:

10.1.3.3.0 10.1.3.3.0 YES
10.1.3.2.0 10.1.3.2.0 YES
When i try not use the following tags section
< init-param>
< param-name>emit_debuginfo< /param-name>
< param-value>true< /param-value>
< /init-param>
everything is working, but ojc not generate debug information for compiled JSP page and debugger doesn't stop at break points.
When i try use thise tags section, i got the next instructions for compiler in MyPage.java (it is generated from MyPage.jsp):
/*@lineinfo:filename=/MyPage.jsp*/
/*@lineinfo:generated-code*/
and compiler is generating next message in console:
error #552: illegal forward reference
07/12/28 11:56:56 /*@lineinfo:filename=/MyPage.jsp*/
and doesn't want to compile MyPage.java.
I need help with this problem! And i don't have any ideas how to solve it. People, help me, please!

Dear dvohra, have you ever try yourself the method, which you suggest?
It is not working!
If i try to configure OC4j like in blog, IDE doesn't stop in JSP's break points.
So, I need in 100% working solution for remote debugging on oc4j 10.3.x. The main reason of using remote debug for me is that i have to develop portlets, and i have to invoke my portlets from portal. It is posible only when i deploy my portlet on stand alone oc4j!
I really need remote debug! And i'll be very thankful someone for 100% working solution!
