exception isn't caught

[tremalnaik]

Hi, I have already posted this on the Tomcat/Servlet forum, because I thought it was a Servlet problem, now I'm not so sure. I hope this is the correct forum.

Have a look to the following piece of code, please. It's a struts action, calling a method on a EJB, throwing a InvalidPasswordException:

public ActionForward execute(...) throws Exception
{
//......
ibsd.saveUserPassword(....);
//........
catch (InvalidPasswordException ipe)
{
ipe.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}

if I deploy the code into jboss version 4.0.0RC1 the exception is caught in the first catch, as expected. Deploying the SAME code into jboss version 4.0.2 leads to an unexpected result: the exception is caught in the secong block, while its stack trace tells it's an InvalidPasswordException:

2005-08-12 16:54:08,343 [http-0.0.0.0-8443-1] ERROR [ROM] com.xxx.web.utilities.InvalidPasswordException: Cannot change password, old password does not match with current password
 at com.xxx.business.util.CurveUserHelper.saveUserPassword(UserHelper.java:523)
 at com.xxx.business.ejbs.implementations.StarClientDataBean.saveUserPassword(StarClientDataBean.java:282)
 at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

can someone tell me why this happens?

thanks

Debugging jboss code I see now that there is a moment in which the exception is embedded in a MBeanException. Is this useful to understand the cause of this strange behaviour?

thanks,

For JBoss 4.0.2 the classloading was changed so that web applications are isolated from other deployments.

Have you packed your exception twice? Once in the war and once in the jar? If the exception is loaded by two classloaders it is likely that it will appear to be a different class which is why it is skipping the first catch.

You made te right assumption, I deployed a JAR file for EJBs and a WAR file for Servlets and JSP. The exceptions package is included in both. Thanks very much for your help.
