Hi, I am attaching a wsdl that used to work nicely with JBoss 4.0.5. But when I try to generate the java files from the wsdl using the wstools shipped along with JBoss 4.2, it keeps giving me this error. Exception in thread "main" org.jboss.ws.WSException: [JAX-RPC 2.3.1.2] Unable to unwrap model group with multiple particles. at org.jboss.ws.tools.helpers.ReturnTypeUnwrapper.unwrapModelGroup(ReturnTypeUnwrapper.java:120) at org.jboss.ws.tools.helpers.ReturnTypeUnwrapper.unwrap(ReturnTypeUnwrapper.java:87) at org.jboss.ws.tools.WSDLToJava.getReturnType(WSDLToJava.java:632) at org.jboss.ws.tools.WSDLToJava.appendDocParameters(WSDLToJava.java:395) at org.jboss.ws.tools.WSDLToJava.appendMethods(WSDLToJava.java:290) at org.jboss.ws.tools.WSDLToJava.createSEIFile(WSDLToJava.java:588) at org.jboss.ws.tools.WSDLToJava.createSEI(WSDLToJava.java:618) at org.jboss.ws.tools.WSDLToJava.generateSEI(WSDLToJava.java:186) at org.jboss.ws.tools.helpers.ToolsHelper.handleWSDLToJavaGeneration(ToolsHelper.java:303) at org.jboss.ws.tools.WSTools.process(WSTools.java:137) at org.jboss.ws.tools.WSTools.generate(WSTools.java:69) at org.jboss.ws.tools.WSTools.generate(WSTools.java:119) at org.jboss.ws.tools.WSTools.main(WSTools.java:58) Can someone please look at the wsdl and point me the problem in the wsdl?
