HI younsoo
I have had the exact problem while using EJB in one of the nightly builds after beta 1 release. THis is working fine with beta 1 though. ( i havent tried beta 2 yet ). Vidyanand. -----Original Message----- From: Younsoo [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 02, 2002 7:08 PM To: [EMAIL PROTECTED] Subject: A problem in Axis Beta2 when the EJB is called I implemented a webservice with EJB in the Axis beta1. There is a problem in Axis beta2. When the EJB webservice is called, the axis returns a error message. My EJB webservice has 4 operations ( deposit, withdraw, getBalance, and getFormattedBalance ) Here is the error message : AXIS error Sorry, something seems to have gone wrong... here are the details: No such operation 'getBalance' I read the Axis beta2 source code and found the reason why the error occurred. The error position is RPCProvider.java , "processMessage" method. . . . . . . . . . . . . . . . // This may have changed, so get it again... // FIXME (there should be a cleaner way to do this) operation = msgContext.getOperation(); if (operation == null) { QName qname = new QName(body.getNamespaceURI(), body.getName()); operation = serviceDesc.getOperationByElementQName(qname); } if (operation == null) { throw new AxisFault(JavaUtils.getMessage("noSuchOperation", methodName)); <<<== Error occurs in this place. } // Create the array we'll use to hold the actual parameter // values. We know how big to make it from the metadata. Object[] argValues = new Object [operation.getNumParams()]; . . . . . . . . . . . . . . . I think that "server-config.wsdd" file is parsed in WSDDDeployment's constructor, and <service> element's contents are parsed into WSDDService class. public WSDDDeployment(Element e) throws WSDDException { super(e); Element [] elements = getChildElements(e, "handler"); int i; . . . . . . . . . . . . . . . elements = getChildElements(e, "service"); for (i = 0; i < elements.length; i++) { WSDDService service = new WSDDService(elements[i]); deployService(service); } . . . . . . . . . . . . . . . } When WSDDService instance created, WSDDService constructor parses <service> element and calls validateDescriptors () method. A <service> element's subelement, <parameter name="className" value="xxx"/>'s value, java class is loaded. public void validateDescriptors() { String className = this.getParameter("className"); if (className != null) { try { // Will this always be the right classloader? ClassLoader cl = Thread.currentThread().getContextClassLoader(); Class cls = cl.loadClass(className); <<== <parameter name="className" value="xxx">'s xxx class is loaded. desc.setImplClass(cls); initTMR(); String encStyle = (desc.getStyle() == ServiceDesc.STYLE_RPC) ? Constants.URI_CURRENT_SOAP_ENC : ""; desc.setTypeMapping((TypeMapping)tmr.getTypeMapping(encStyle)); } catch (Exception ex) { } } . . . . . . . . . . . . . . . } As you can see above source, the loaded class, cls is set into ServiceDesc.( desc.setImplClass(cls); ) In setImplClass () method operations(xxx class's methods) are instantiated into OperationDesc class. public void setImplClass(Class implClass) { if (this.implClass != null) throw new IllegalArgumentException( JavaUtils.getMessage("implAlreadySet")); this.implClass = implClass; if (Skeleton.class.isAssignableFrom(implClass)) { isSkeletonClass = true; loadSkeletonOperations(); <<== OperationDesc instances are set. } } Here is my "server-config.wsdd" file's part . There is no <parameter name="className"> subelement in EJB <service>. Therefore OperationDesc instances couldn't be created. msgContext.getOperation() and serviceDesc.getOperationByElementQName(qname) in RPCProvider.java , "processMessage" method couldn't retrieve OperationDesc instance. So AxisFault(JavaUtils.getMessage("noSuchOperation", methodName)) is thrown. <!-- As you can see, this is a webservice using general java class --> <service name="Add" provider="java:RPC"> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="Request"/> <parameter name="className" value="samples.TestWS.WebServiceTest"/> </service> <!-- a webservice using EJB --> <service name="MyAccount" provider="java:EJB"> <parameter name="allowedMethods" value="*"/> <parameter name="jndiURL" value="localhost"/> <parameter name="scope" value="request"/> <parameter name="beanJndiName" value="TestAccount"/> <parameter name="homeInterfaceName" value="testaccount.TestAccountHome"/> </service> How can I make a webservice using EJB?
