Subject Re: Struts 2: Unable to catch exceptions via global-exception-mappings
Date Mon, 01 Oct 2007 15:28:12 GMT

thanks for looking.  I pasted the full stack trace below.   I am not using
any home grown action code (yet). This is coming from the
DefaultActionSupport during the rendering stage.

com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:348)

Do I need to subclass and do something in the action.execute() code ?


here's the full trace
