hello,

i 've got this exception

java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at
sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39)
    at
sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25)
    at java.lang.reflect.Method.invoke (Method.java:585)
  ....
    at java.lang.Thread.run (Thread.java:595)
Caused by: java.lang.NullPointerException
  ....

in my web.xml, i put this xml tags:

<error-page>
    <error-code>404</error-code>
    <location>/serv/ErrorBis</location>
</error-page>

<error-page>
    <exception-type>java.lang.NullPointerException</exception-type>
    <location>/serv/ErrorBis</location>
</error-page>

<error-page>

<exception-type>java.lang.reflect.InvocationTargetException</exception-type>
    <location>/serv/ErrorBis</location>
</error-page>

the exception is not handling for this exception. it works well for a
404 exception but not for a nullPointer...

could you tell me why?

regards
Fred
