An example of an AI chatbot conversation about creating custom error pages in Java.
How can I create custom error pages in Java?
You can create custom error pages in Java by configuring your web application's deployment descriptor (web.xml) to specify error page mappings.
Can you show me an example of how to configure that in web.xml?
Sure! Here's a simple example:
<error-page>
<error-code>404</error-code>
<location>/error404.jsp</location>
</error-page>
What about handling exceptions? Can I create custom pages for those too?
Yes, you can handle exceptions by specifying the exception type in the web.xml. For example:
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.jsp</location>
</error-page>
Is there a way to log these errors as well?
Absolutely! You can use a logging framework like Log4j or SLF4J to log errors when they occur, which can help in debugging.
