Error Handling Websphere

[James Ellis]

I am new to Websphere, and I'm coming from a Tomcat world where creating an error page for exception types is as easy as adding the following to the web.xml file:

<error-page>
        <exception-type>java.lang.Throwable</exception-type>
        <location>/error/error.jsp</location>
</error-page>

If I want to create custom error pages in Websphere Commerce version 5.6.1 how do I do this? I've tried updating the web.xml through the IBM Websphere Studio Application Developer but it keeps giving me a message "Some files are read-only" even though on the filesystem the file is NOT read-only.

Is there an Websphere specific way of doing this such as through the admin console or through some other IBM specific interface?

Thanks,
Jim

According to the websphere forum, YES this is how I should be doing error handling. By updating the web.xml files.
