Whenever there is something wrong with a jsp page the only message IS returns is:
2004-01-14 12:32:57 GMT+13:00 [ISS.0100.0005E] Web Container error encountered: :StandardWrapperValve[jsp]: Servlet.service() for
servlet jsp threw exception
2004-01-14 12:32:57 GMT+13:00 [ISS.0100.0005E] Web Container error encountered: ISConnector.invoke:java.lang.NullPointerException
This is pretty unhelpful for debugging JSP pages. The only way around it I see is to use out.println and comment out code until you find the culprit.
Otherwise use a JSP editor.
Is there anyway of viewing the errors in IS?
