Thanks for your answer, but it is not exactly what I mean.
I think, ihat I have misformulated my question and will ask with other words:


There are two different ways to create the webServices:

1) One is to create the WSDL-File manually and then autogenerate the 
Java-Files with "wsdl2java".



2) The way, which I use in the moment: (with jboss-net, the axis-Version, 
which is integrated in JBoss.)

I create the WSDD-Description manually, put it in a *.wsr 
WebService-Archive and JBoss generates automatically the
WSDL-File. I can watch this file with: 
http://<servername>/jboss-net/services/<servicename>?wsdl

Then I create a Service call in the client class:

String endpoint = "http://<servername>/jboss-net/services/<servicename>";
String methodName = "test";

Service service = new Service();
Call call = (Call) service.createCall();

call.setTargetEndpointAddress( new java.net.URL(endpoint) );

call.setOperationName(methodName);
Object ret = call.invoke(new Object[]{});


Now again my question:
Which is the better way for developing Web Services to use with existing 
JavaWebStartClient and EJBs.
Has the result of both ways the same performance?

They should be the same.
