APAR status

Closed as program error.

Error description

JspApplicationContext.addELResolver() in a servlet is not
throwing an IllegalStateException. Where as an
IllegalStateException should be thrown if an attempt is made to
call this method after all ServletContextListeners have had
their contextInitialized methods invoked.

Note: This failure only occurs when the addELResolver method is
called in a servlet and works fine in a JSP.

****************************************************************
According to the JSP specification for addELResolver(): it is
illegal to register an ELResolver after the application has
received a request from the client. If an attempt is made to
register an ELResolver after that time, an
IllegalStateException is thrown.

However, in the WebSphere Application Server servlet engine
implementation, registration of an ELResolver from a servlet
or a filter is allowed after the application has received a
request from the client. Note: This is not a problem if
addELResolver() is called in a JavaServer Page (JSP).

Problem conclusion

The WebContainer and JSP containers have been modified to
throw an IllegalStateException if an attempt is made to
register an ELResolver after the application has received a
request from the client.
The new webcontainer custom property will be required to be set
to enable the new behavior

com.ibm.ws.jsp.throwExceptionForAddELResolver = true (default
= false)

Please refer to the following technote for instructions on
enabling WebContainer custom properties:

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.11.  Please refer to the Recommended Updates
