How to handle JSP exceptions declaratively

[Neeraj Singhal]

Is it possible to handle JSP exceptions declaratively through web.xml ?

[Prakash Dwivedi]

There are two ways to handle exception in JSP declarativly. Add the code in web.xml.
First:
In this you can define http error code

  
<error-page>
<error-code>403</error-code>
<location>/errorpages/securityerror.jsp</location>
</error-page>

Second
In this you can define Exception Type

<error-page>
<exception-type>java.sql.SQLException</exception-type>
<location>/errorpages/sqlerror.jsp</location>
</error-page>

To help the error handler JSP analyze the problem and generate a detailed response, the servlet container sets certain attributes in the request before dispatching it to the error page. Like
javax.servlet.error.exception_type Contains the Class object for the
uncaught exception

The suggestion from Prakash can also be used for Servlets, not only JSPs.

I had already tried these....but of no help
<error-page>
<error-code>*</error-code>
<location>/error.jsp</location>
</error-page>
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>/error.jsp</location>
</error-page>
whenever an exception occurs in jsp page....
the browser says...page cannot be displayed.

forgot to mention.....
I am using this with struts. Is it possible that this behaviour is happening due to that.

[Nicholas Cheung]

If Struts is used, then you should not define the error in web.xml.
Instead, you should handle the exception in the struct-config-xxx.xml file, add the local exception to the config, so that corresponding page can be re-directed to .

But, through struts-config.xml, we can handle validation errors only.
How can we handle runtime exception (JasperException) and redirect to some error page.

Did you ever figure out how to do this?
