Hi, I have made sure that none of the other jars implements the javax.xml.rpc package. But, never mind, it is now working. I have no idea why. There is still one thing that bothers me though. One of the services I am calling can be invoked by using just four lines of code, i.e.
Call call = (Call)service.createCall(); call.setTargetEndpointAddress(new URL(wsEndpoint)); call.setOperationName( new javax.xml.namespace.QName(wsNamespace,wsMethod)); ret = call.invoke(val); For another service this simple approach did not work. The invoked service complained that it did not correctly receive the input value. I needed additional code as such: oper = new org.apache.axis.description.OperationDesc(); org.apache.axis.description.ParameterDesc param = new ... oper.addParameter(param); oper.setReturnType(... call.setOperation(oper); Why is this ? Regards & thanks, Juliane. ________________________________ From: jayachandra [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 4.

If you copied jaxrpc and axis jars in your webapps context classpath (i.e. WEB-INF/lib) folder, do check what other jars you have and see if any of them have implementation of this package.
