Using Axis 1.0 RC2, WebLogic 7.0.1, and EJB Provider. Deployed a HelloWorld stateless session bean with a hello() method that returns a String. No problem calling it from a Java client using JNDI. Now exposed this EJB as a Web Service. Assume this was done successfully because I could get the WSDL file from http://localhost:8080/axis/services/HelloEJBService?wsdl. Used the WSDL2Java util to generate all the client-side service locator and SOAP binding stub classes. Wrote my little test client using these classes. Ran this test class, got AxisFault with underlying NullPointerException. Then tried a VB6 client using MSXML.XMLHttpRequest object and posting a SOAP request. Got the same AxisFault back. Has anyone successfully used the Axis EJB Provider with WebLogic? My code is attached. Thanks.
