You should override the method unspecified. Check out the DispatchAction Java doc:
http://jakarta.apache.org/struts/api/org/apache/struts/actions/DispatchActio n.html#unspecified(org.apache.struts.action.ActionMapping,%20org.apache.stru ts.action.ActionForm,%20javax.servlet.http.HttpServletRequest,%20javax.servl et.http.HttpServletResponse) -----Original Message----- From: Wendy Smoak [mailto:[EMAIL PROTECTED]] Sent: Monday, February 03, 2003 3:05 PM To: 'Struts Users Mailing List' Subject: RE: how to handle method not found in DispatchAction > suppose I have a following URL > /pages/MyDispatchAction.do?nextpage=home > and class MyDispatchAction has a method > public ActionForward home(...) > so this request is handled by this method, > Suppose there is a request to DispatchAction , for > which there is no method to handle it , it crashes, > Is there a way to forward all these request to a > default page, if there is no method to handle the > request??? > Has anyone written or done some thing like this to > handle this error neatly I override execute() and provide a default, but my main problem is the action being called *without* the parameter, not with one that doesn't have a mapping. public final class EditContactAction extends LookupDispatchAction { public ActionForward execute( ... ) { if ( request.getParameter( mapping.getParameter() ) == null ) { log.debug( "parameter is missing, defaulting to add" ); return addContact( mapping, form, request, response ); } else { log.debug( "parameter present, calling super.execute" ); return super.execute( mapping, form, request, response ); } } } Sounds like you would need to do something like: if ( !getKeyMethodMap.containsKey( request.getParameter( mapping.getParameter() ) ) { ... } (But my getKeyMethodMap creates a new Map every time, and I wouldn't want to do that... perhaps the Map should be a class variable instead.) Personally I would like to see a 'default' attribute for the <action> tag. That way LookupDispatchAction could itself fall back on a default value if the specified parameter is missing or not in the Map. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University PA Information Resources Management *************************************************************************** This electronic mail transmission contains confidential and/or privileged information intended only for the person(s) named.
