Hi there! I have posted over a dozen questions in this forum but haven't gotten a reply to even one. I hope atleast this one qualifies for a reply. I am using jbossws 1.2.0 installed in jboss server 4.0.5. i try to deploy a jaxws webservice that consists of methods accepting an array of custom classes as a parameter and returning an array of strings. i get an exception on deployment which is quite tough to debug. any help/insight into this would be a big help. i am in a fix, and need a solution quickly. the exception i get is : [ServiceEndpointDeployer] Cannot create service endpoint java.lang.ClassCastException: com.sun.xml.bind.v2.model.impl.RuntimeBuiltinLeafInfoImpl$5 The complete stack trace is below: 22:04:35,219 ERROR
