Hi BVO, We really need to know what ClassUtils.forName(pivotQName.getLocalPart()).newInstance().getClass() evaluates to in the case of error.
Jeff ----- Original Message ----- From: "BVG" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, June 15, 2005 4:35 AM Subject: Re: classloader problem Hi Jeff, The stub call is done in the JAAS module (file: SampleLoginModule.java), this module is configured on Tomcat application, and when I press the authentication form the JAAS module runs. When it runs, call the VerificaAutenticacao WebService, which returns some values to check if this user is authenticate. It's in this call that I got a CastClassException on the file WSDDTargetedChain.java:157(Axis code), and in there I see different ids for the same Handler: "ClassUtils.forName(pivotQName.getLocalPart()).newInstance().getClass().getS uperclass().getInterfaces()" = java.lang.Class[1] (id=85) "Class.forName("org.apache.axis.Handler")" = java.lang.Class (org.apache.axis.Handler) (id=91) But, if I call the same webservice but outside that JAAS module, everything works, and the ids are the same for the same handler: "ClassUtils.forName(pivotQName.getLocalPart()).newInstance().getClass().getS uperclass().getInterfaces()" = java.lang.Class[1] (id=85) "Class.forName("org.apache.axis.Handler")" = java.lang.Class (org.apache.axis.Handler) (id=85) Any ideas? humm.. :( Thanks one more time Jeff Jeff wrote: >In a discussion about error handling a while back, I mentioned to James >Taylor how insane it is to report a ClassCastException without citing the >offending class. > >Presumably you know which class your handler is or can look it up in the ><handler> element of your deployment descriptor.
