Struts 2: Unable to catch exceptions via global-exception-mappings
I am unable to trap an exception and it's being pushed up until it becomes a
500 Servlet Exception.
Basically, I want to catch the exception if a user mistypes an action name
I am using struts2 (2.0.9).
Here's the top of the trace:
org.apache.velocity.exception.ResourceNotFoundException:
Unable to find resource '/templates/screens/inddd2ex.vm'
at
org.apache.velocity.runtime.resource.ResourceManagerImpl.loadResource(ResourceManagerImpl.java:458)
Here's my struts.xml file
(thanks for helping)

You are right... I am just trying to catch those rare events.
Now here's something crazy: (and I have checked, and double checked,
restarted server, etc).
BUT if I add a to my action, the exception mapping WORKS. If I take it
away, the exception is
not caught.
<action name="*" class="com.opensymphony.xwork2.ActionSupport">
bar
<interceptor-ref name="exception" />
<interceptor-ref name="defaultStack" />
<result type="velocity">/templates/screens/{1}.vm</result>
</action>
That works like a charm, remove the foo/bar and I get 500 error. struts.xml
file is the same as I posted.
Any ideas?
Perhaps, this could be a separate thread. But while debuging this, I added

Re: Struts 2: Unable to catch exceptions via
global-exception-mappings
Posted by mikeh96 <mi...@ncsa.edu>.
the previous posting seems to not like the \<param\>
You are right... I am just trying to catch those rare events.
Now here's something crazy: (and I have checked, and double checked,
restarted server, etc).
BUT if I add a <param> to my action, the exception mapping WORKS. If I
take it away, the exception is
not caught.
<action name="*" class="com.opensymphony.xwork2.ActionSupport">
<param name="foo">bar</param>
<interceptor-ref name="exception" />
<interceptor-ref name="defaultStack" />
<result type="velocity">/templates/screens/{1}.vm</result>
</action>
That works like a charm, remove the foo/bar and I get 500 error. struts.xml
file is the same as I posted.
Any ideas?

Yes, that's definitely a valid approach.
I guess the question I have is "how are you using the feature?" It
looks like you are simply providing a pass-through to view a velocity
template that is the same as the action name. Are you expecting the
user to make a request to a template that will not exist? I find that
most of the time, once construction is complete, exceptions such as the
one you are getting are never thrown, because the paths through the site
are well know.

Re: Struts 2: Unable to catch exceptions via
global-exception-mappings
Posted by mikeh96 <mi...@ncsa.edu>.
Thanks for the clarification. Is the solution of extending VelocityResult
and configuring it with a
template name to return (e.g. 404.vm) if the requested template throws the
ResourceNotFoundException
a viable one ? Or is there a way to handle this more elegantly ?
thanks again for your time!

Re: Struts 2: Unable to catch exceptions via global-exception-mappings
Posted by Ian Roughley <ia...@fdar.com>.
The result is executed after the interceptors and after the action has
executed. Look at the invoke() method on the DefaultActionInvocation
class. Therefore, because your exception is in rendering the result,
the exception is not managed by the interceptor. If you threw the same
exception from within the execute() method of an action, it would be
handled as you are expecting.
I think this comes down to the reasoning behind the interceptor. I see
it as a means to manage the run-time business logic, and not
developer-based configuration which will usually be managed during the
construction phase.

Re: Struts 2: Unable to catch exceptions via
global-exception-mappings
Posted by mikeh96 <mi...@ncsa.edu>.
thanks for looking. I pasted the full stack trace below. I am not using
any home grown action code (yet). This is coming from the
DefaultActionSupport during the rendering stage.
com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:348)
Do I need to subclass and do something in the action.execute() code ?
here's the full trace

Re: Struts 2: Unable to catch exceptions via global-exception-mappings
Posted by Ian Roughley <ia...@fdar.com>.
Is the exception occurring during the call to execute() (or equivalent)
business logic method? This is where the exception handler interceptor
is applied. It seems like the exception you are receiving is from a
rendering phase outside the execution of the actions logic.

Thanks for taking the time.. unfortunately, the exceptions are still
percolating up.
Do you have it working?

I am not 100% sure on this, but I think you need to have
struts.devMode = false in struts.properties.
Give that a whirl.
