The application.log file of the OACore OC4J shows the following error stack:

javax.servlet.ServletException: oracle.classloader.util.AnnotatedClassNotFoundException:

Missing class: _RF

Dependent class: oracle.jsp.runtimev2.JspPageInfo        

Solution :

To implement the solution, please execute the following steps:

Either:

A. Set the JSP compilation to Automatic using the following steps:

1. Use the vi editor to edit the $CONTEXT_NAME.xml context file used by AutoConfig and change the value for "s_jsp_main_mode" from "justrun" to "recompile" (without the double quotes)

NOTE

~~~~~

Backup the context file before editing it.

2. Run Autoconfig to propagate the changes to the configuration files.

3. Verify that now the

$INST_TOP/ora/10.1.3/j2ee/oacore/application-deployments/oacore/html/orion-web.xml has

<init-param>

<param-name>main_mode</param-name>

<param-value>recompile</param-value>

</init-param>

4. Restart the Middle Tier services and access the applications to load JSP's which will cause them to be recompiled on the run.

5. After successfully accessing the applications, use the vi editor to edit the $CONTEXT_NAME.xml context file used by AutoConfig and revert the value for "s_jsp_main_mode" to "justrun" (without the double quotes) in order not to hamper the performance of your system.

EX:

[oracle@svrqatal2 ~]$ grep -i s_jsp_main_mode $CONTEXT_FILE

         <jsp_debug_parameters oa_var="s_jsp_main_mode">justrun</jsp_debug_parameters>

6. Run AutoConfig to propagate the changes.

NOTE

~~~~~

You can always use the next option to compile JSP's manually at any time.

OR

B. Recompile the JSP manually using the following steps:

1. Telnet to your server using applmgr user and source the environment by running the script:

/oracle/apps/apps_st/appl/APPS<SID>_<host>.env

2. Run the commands

cd $FND_TOP/patch/115/bin

perl ojspCompile.pl --compile --flush -p 2
