Can anyone let me know the differences between (1) and (2): Thanks


(1) In struts-config.xml
<global-exceptions>
     <exception key="someerryorKey"
       type="java.lang.Exception"

handler="com.....handler.MyCustomExceptionHandler"
       path="errorPageForward">
     </exception>
 </global-exceptions>

(2) In web.xml
<error-page>
<exception-type>Exception</exception-type>
<location>/MyError.jsp</location>
</error-page>

this.href will give you the href value; I assume what Musachy posted
will give you the OGNL evaluated value. Why can't you use that?

I don't know if it would help you, but whenever I've had the
phenomenon of repeating content on a page, it is almost always related
to encountering an exception in one of the struts iteration tags. The
first place I look are the log files to see if there's a stack trace.

Hope that helps.
