[Actionframework-users] Tryin to catch component exceptions

[<ser...@is...>]

Hi all!!

I'd like to catch some exceptions that my application may throw under=20
certain circumstances, in order to control a little bit the flow of the=20
app and avoid Tomcat to stop suddenly while posting a "the document=20
contains no data" message.

The thing is that i have 3 <on-exception> elements under all the=20
<action>s tags, and the thing goes ok. The elements are these:


<on-exception class=3D"java/lang/NullPointerException" assign-to=3D"npe"=20
show-template=3D"error.vm">
                <output-variable name=3D"obj" value=3D"$npe"/>
</on-exception>
          =20
=20
<on-exception class=3D"java/lang/NumberFormatException" assign-to=3D"nfe"=
=20
show-template=3D"error.vm">
    <output-variable name=3D"obj" value=3D"$nfe"/>
</on-exception>
          =20

<on-exception class=3D"raiz/ExcepcionErrorDatos" assign-to=3D"eed"=20
show-template=3D"error_datos.vm">
    <output-variable name=3D"mensaje" value=3D"$eed.getMessage()"/>
</on-exception>

However, when i add a java.lang.Exception and a=20
org.apache.commons.dbcp.SQLNestedException (both at the end), the page=20
fails and doest show anything. Only putting those <on-exception>s tags=20
makes the app fail, coz when i comment them, it goes fairly well.

What am i doing wrong? What should i do to catch SQLNestedException and=20
Exception?

Thanx in advance........
