Hi, I tried the following webservice , package com.javasrc.webservices.age; public class AgeServlet { public String age( String name, Integer age ) { return name + " is " + age + " years old!"; } } SEI is , package com.javasrc.webservices.age; import java.rmi.Remote; import java.rmi.RemoteException; public interface Age extends Remote { public String age( String name, Integer age ) throws RemoteException; } web.xml <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4"> <servlet-name>AgeServlet</servlet-name> <servlet-class>com.javasrc.webservices.age.AgeServlet</servlet-class> <servlet-mapping> <servlet-name>AgeServlet</servlet-name> <url-pattern>/Age</url-pattern> </servlet-mapping> </web-app> used this config file <?xml version="1.0" encoding="UTF-8"?> to generate wsdl and mapping file using Webservices Developer Pack which runs on jre 1.5 and my jboss server runs on java 1.4 my directory structure looks like , age.war /WEB-INF /classes mapping.xml web.xml webservices.xml /wsdl AgeService.wsdl When I opened up mapping and webservices.xml in jboss IDE 2 Beta , it showed some schema errors. cvc-id.3: A field of identity constraint 'port-component-name-key' matched element 'webservice-description', but this element does not have a simple type. I resolved this by removing , 'http://java.sun.com/xml/ns/j2ee from the following <?xml version='1.0' encoding='UTF-8'?><java-wsdl-mapping version='1.1' xmlns='http://java.sun.com/xml/ns/j2ee' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://java.sun.com/xml/ns/j2ee http://www.ibm.com/webservices/xsd/j2ee_jaxrpc_mapping_1_1.xsd'>;. And then published using jboss IDE Beta. Though I see the webservice in the console http://localhost:8080/jbossws/services , I couldn't invoke the webservice using client program in which I was thrown with error 500. How do I resolve this ? Any help would be greatly appreciated. Is the jbossws is a suggested environment to develop webservices?
