-----------------------------------
With all due respect this kind of behavior is a real pain especially if you are
in the middle of heavy refactoring. This is maybe not a problem but for sure a
pain.
If you could pinpoint in the output to:
- the XML file which cannot be used for the configuration (or lets dream the
line too)
- the class which is not found
this would be much helpful.
I do not know about other files used by Struts2 such as Validator.xml can have
the same problems but if this this the case then same expected behavior.
BTW I do not use Spring at all in my project, there is no Spring library in my
environment.
>From what I have seen in ObjectFactory.getClassInstance() of xworks2.0.4.jar
>the call does not log a message.
The same for ClassLoaderUtil.loadClass() in the same file.
ObjectFactory IMO should log something.
Thanks

> Project: Struts 2
> Issue Type: Improvement
> Components: XML Configuration
> Affects Versions: 2.0.11
> Environment: Windows XP SP2, Tomcat 5.5 JDK 1.5.0.12

> A ServletException without details seems thrown when an action listed in
> Struts.xml is not found, add details in the exception and log a fatal error
> Take your struts.xml which runs fine and having a line such as
> <action name="home"
> class="pwgsc.rpgis.struts.common.HomeAction">
> <result type="tiles" name="success">home</result>
> </action>
> Now in your IDE, rename the class HomeAction to HomePageAction or move it in
> a different package.
> My RSA IDE knows nothing about Struts 2 so suddenly struts.xml is no more
> accurate.
> Start the server, on the initialization of the Struts2 filter, in init() the
> file seems to be parsed and certainly instances of the actions created.
> Whatever, the init() fails and all I get from the Tomcat output is "SEVERE:
> Error filterStart."
> I have tried to increase the logging, log4j being configured and initialized
> before Struts2 with Struts2 and XWork both configured as DEBUG
> I have struts.devMode = true in struts.properties
> No way to figure out what it was. It took me some time to figure out what was
> the issue.
> The problem can be reproduced every time.
> I strongly suggest to create a clear ServletException in your filter using
> the constructor with the String specifying the offending class or the part of
> the configuration file(s) which is bad (file + line)
> In addition of that, I would suggest to use commons logging to display a
> clear fatal message with details.
> It's quite weird to see all the amount of logging when it is turned on when
> processing a request while nothing is logged at the initialization of the
> filter.
