Blank Page Accessing R12 - 'Missing class: _RF' in OACore application.log:
===============================================================
On 12.0, trying to connect to the home page, which shows a blank page.
Further more, 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
Loader: oc4j:10.1.3
Code-Source: /oracle/apps/tech_st/10.1.3/j2ee/home/lib/ojsp.jar
Configuration: code-source in META-INF/boot.xml in /oracle/apps/tech_st/10.1.3/j2ee/home/oc4j.jar
This load was initiated at oacore.web.html.jsp8892557:0.0.0 using the loadClass() method.
The missing class is not available from any code-source or loader in the system.

To solve this issue, there are two ways
1. Set the JSP compilation to Automatic
2. Recompile the JSP manually
How to set the JSP compilation to Automatic
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)
Backup the context file before editing it.
Run Autoconfig to propagate the changes to the configuration files.
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
Restart the Middle Tier services and access the applications to load JSP's which will cause them to be recompiled on the run.
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.
Run AutoConfig to propagate the changes.
How to recompile the JSP manually
You can always use the this option to compile JSP's manually at any time.
Connect application tier using applmgr user and source the environment by running the script:
/oracle/apps/apps_st/appl/APPSSID_host.env
Run the commands
UNIX
cd $FND_TOP/patch/115/bin
perl ojspCompile.pl --compile --flush -p 2
