parameters of first method might have been simple/native types like int etc. which the Axis runtime could have intelligently (un)marshalled, and those of second might not have been so easy ones for which reason extra ParameterDesc object would have helped axis find the proper ser/deser factories to marshall/unmarshall the object.

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.

Looks like there is another jar implementing the javax.xml.rpc package in the classpath.
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.
Hope that helps,

Hi Johann,
but I do have jaxrpc.jar in the lib directory.

Hi,
Your import are correct, just the jaxrpc.jar is a dependance for Axis.
jaxrpc.jar must be in the same directory as axis.jar etc.
