Exception management with Tomcat (URGENT)

[Heligon Sandra]

        I defined a class MyServletContextListener where I use exceptions
        for example:

         public void contextInitialized(ServletContextEvent arg0) 
         {
                s_context = arg0.getServletContext();
                try
                 {
                ...
                }
                catch (ExInvalidUserName ex)
                {
                        ??
                }
                catch (ExInvalidPassword ex)
                {
                        ??
                }
                catch (ExInvalidSessionId ex)
                {
                                ??
                }
        }

        In the web.xml I defined the following elements:

        <error-page>
 
<exception-type>org.omg.CORBA.UserException.ExInvalidUserName
</exception-type>
                <location>/errorPage.jsp</location>
        </error-page>
        <error-page>
 
<exception-type>org.omg.CORBA.UserException.ExInvalidPassword
</exception-type>
                <location>/errorPage.jsp</location>
        </error-page>
        <error-page>
 
<exception-type>org.omg.CORBA.UserException.ExInvalidSessionId
</exception-type>
                <location>/errorPage.jsp</location>
        </error-page>

        The error message displayed in the errorPage.jsp file depends on the
exception.
        How does it works ? Where do I specify the error message associated
to each specific exception ?
        in the following lines ?

        catch (ExInvalidUserName ex)
        {
                // Specify the error message to display ???     
        }

        Thanks a lot for you help,
        Sandra
