Symptoms

On R12, trying to connect to the home page (http://<server>.<domain>.<port#>), redirects to http://<server>.<domain>.<port#>/OA_HTML/AppsLocalLogin.jsp 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.
