Hello, I am using JBoss4.0DR2 and got this error:ClassCastException: This attachment implementation accepts only SOAPPart objects as the root part. My web services worked fine under Tomcat 4.1.24, so I don't know why they are failing under JBoss. I have never seen this error before, and don't even know where to start to resolve it. You can find my wsdl file at http://dante.acomp.usf.edu:8080/axis/services/GraphingTools?wsdl Thank you for any help.
