    Can't use errorPage. Any idea why?

    L.G. Newbie

      In jboss-2.6 I had no problem to display exceptions in errorPage, but in jboss-3.0.1 I always get error in blank html page. Anybody has such problem?

      TIA

          Hi,
          perhaps you should add :
          <%@page errorPage="True%>

          at top of your JSP files.

          and
          "
          <error-page>
          <error-code>403</error-code>
          /default.jsp
          </error-page>
          <error-page>
          <exception-type>java.lang.Exception</exception-type>
          /error.jsp
          </error-page>
          <error-page>
          <exception-type>java.sql.SQLException</exception-type>
          /sqlException.jsp
          </error-page>

          "
          at web.xml


          hope you are happy

            Thanks for reply,
            Yes I'm using <@errorPage="errorPage.jsp"@> and <@isErrorPage="true"@> in error page.
            Without <error-page>...</error-page> in web.xml I get error in regular html page, not the errorPage.jsp.
            When I add <error-page>...</error-page> I get empty html page and in log file
            I see another error (not related to exception I throw from my code):

                Hi, as my understanding:

                <@errorPage="errorPage.jsp"@> is used to forward the page error to errorPage.jsp, and

                <@isErrorPage="true"@> seems that this JSP file can receive and display Exception information.

                so,you should add <@isErrorPage="true"@> to errorPage.jsp,
                or it display empty page without Exception info.

                if you use <error-page/> tag you not need to add <@errorPage="errorPage.jsp"@> in every jsp, because system can automatically capture all Exception info to forward to error-page file.

                in addition, the NullPointerException in log file is from your JSP file,not errorPage.jsp


                maybe above is useful.

                  The problem was using filters. If in filter exception is thrown then errorpage does not triggered by the system,
                  so I have to manually forward to errorpage. :(
