Agood way that i have found out was to define a BaseExceptionHandler.java class
< snip >
public final class BaseExceptionHandler extends ExceptionHandler {
public ActionForward execute(Exception ex, ExceptionConfig ae,
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException {
ActionErrors errors = (ActionErrors)
request.getAttribute(Globals.ERROR_KEY);
if (errors != null) {
return null;
}
ActionForward forward =
super.execute(ex, ae, mapping, form, request, response);
// get user that is logged in from session
// create a timestamp (String)
StackTraceElement[] ste = ex.getStackTrace();
StringBuffer sbStackTrace = new StringBuffer();
for (int i = 0; i<ste.length; i++) {
sbStackTrace.append(ste[i].toString());
sbStackTrace.append("\n");
}
// create a unique error code from userName_Timestamp
// Save the error code in the session
if ( session != null ){
session.setAttribute("errorId", sb.toString());
}
//return new ActionForward(ae.getPath());
return forward;
} // end execute
}
< / snip >
Now in your struts-config.xml have this in there
<global-exceptions>
<exception key="errors.technical.difficulty"
path="/jsp/systemError.jsp" type="java.lang.Exception"
handler="com.path.to.my.class.BaseExceptionHandler"/>
</global-exceptions>
and aboviously "errors.technical.difficulty" would be in the resource
properties file, waht ever message you want to display
Now in the systemError.jsp, display the errorId....
This is a catch all error, design pattern......
When a user reports a error ask for the error Code on the screen and
then you check your log4J file for that error code to debug.
hope that helps :)
