500 Internal Server Error

Last day i was open my Oracle Apps Front hand login page Got below Error.

ERROR:-
500 Internal Server Error OracleJSP: An error occurred. Consult your application/system administrator for support. Programmers should consider setting the init-param debug_mode to "true" to see the complete exception message.

Solution:-

Please go to $ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/global-web-application.xml

Extend the servlet node this way:

<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>
 
 
Restart OC4J and thats should be it.
Also have a look at $ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/application-deployments/ses_query/application.log
