The second method, Web. XML, defines the processing page

I know that there are two ways to configure Error-page in Web. XML, one is to configure by error code, but to configure it by the type of exception, respectively, as follows:

A. Configuring Error-page with error codes

Eg.

<error-page> <error-code>500</error-code> <location>/error.jsp</location> & Lt;/error-page>

The above is configured to jump to the error handling page error.jsp when the system has a 500 error (that is, a server internal error).

two. Configuring Error-page by type of exception

Eg.

<error-page> <exception-type>java.lang.NullException</exception-type> <location>/e Rror.jsp</location> </error-page>

configured above when the system occurs java.lang.NullException (i.e. null pointer exception), jump to error handling page error.jsp
