Configuring default error page

[pa12399]

Hi

I am using JBoss 4.2.2

I am trying to configure a default error handling, where the error handling component is a servelt, which will simply catch the exceptions which are not caught by the other application servlet and then log it in a specific format.

I have created this entry in server/myapp/deploy/jboss-web.deployer/conf/web.xml

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- Catch a whole class of errors -->
<error-page>
<exception-type>java.lang.NumberFormatException</exception-type>
/error.ErrorServlet
</error-page>
</web-app>

The ErrorServlet is under ROOT.war/WEB-INF/lib/myapp.jar

But it doesnt seem to be catching the exceptions. Instead I see the exception just getting displayed in server.log

Any help would be greatly appreciated.

Thank you

The global web.xml file, which you modified, is combined with the web.xml file for your app to make the configuration for your web app. Thus I believe it expects the servlet to be in your web app.

You are going to have to play around with different configurations to find one that might work. A possibility might be to send the errors to an HTML page in ROOT.war (which I think you were already able to do), and have the HTML page redirect to a global servlet (since you can use a full URL there).
