Exception handling in Struts
Hello, I'm trying to capture exceptions generated inside my jsp pages.
I wrote a piece of code like this into my jsp:
<%
......
DatabaseException de = new DatabaseException("Test Exception for the
error page");
throw de;
.......
%>
I added these pieces in my web.xml and struts-config.xml
----------------------------web.xml-----------------------------
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>/error.jsp?code=exception</location>
</error-page>
----------------------------web.xml-----------------------------
----------------------------struts-config.xml-----------------------------
<global-exceptions>
<exception key="error.application"
path="/error.jsp?code=exception" type="java.lang.Exception"/>
</global-exceptions>
----------------------------struts-config.xml-----------------------------
I'm using the sslext SecureTilesRequestProcessor defined as:
<controller processorClass="org.apache.struts.action.SecureTilesRequestProcessor"
/>
I'm not able to capture the exception thrown by the jsp page. The result is:
[ServletException in:/jsp/admin/groupListBody.jsp] Test Exception for
the error page'
written on the browser page, instead of the page generated by error.jsp
what's I'm doing wrong?
thanks in advance

well, I'm using it (see my original posting), but the exception is not
caught, simply ignored. Anyway you are right when you say that the
exception should always be caught by the action class. I wanted to
make my jsp really secure whatever exception may be thrown, but
probabily I'm just a bit paranoid.
thanks

Probably want to use the web.xml exception stuff, then (error-page
element, maybe?)
Ideally, there should be VERY little that can go wrong within a JSP; if
presentation/everything else is handled within Struts, helper classes,
custom tags, etc.--then the exceptions WILL be caught by struts.
What kind of exceptions do you anticipate being thrown by the JSP itself?

ok, anyway I'm looking for a way to catch all the exception thrown by
may app. So throwing a dbexception was just an example. There is
always something that may go wrong within a jsp.
thanks, anyway

Struts can't catch exceptions thrown by the JSP. This is one reason
(among many) why I would design something like this to do the
database work in an action and deliver only data to the JSP.
