How to prevent downloading wsdl in weblogic web service client

Question

Hi,
I get a problem regarding weblogic web service client. My working environment:
weblogic server 8.1
Windows XP SP2
JDK 1.4
I use the weblogic tool to generate the client jar file from the wsdl file.
     <target name="generate-client">
          <clientgen wsdl="ACCESS.wsdl"
               packageName="xxxxxx.client"
               clientJar="${client}/${AccessClient_jar_file}"
               keepGenerated="true"
               saveWSDL="true"
          />
          <javac srcdir="${source}"
          destdir="${client}"
          includes="**/AccessClient.java">
          <classpath>
          <pathelement path="${client}/${AccessClient_jar_file}"/>
          </classpath>
          </javac>
     </target>
After that, I create a client java file to invoke the service deploy in the server.
public static void main(String[] argv)
throws Exception
     int transactionId = 100;
     int id = 1000;
// Setup the global JAXM message factory
System.setProperty("javax.xml.soap.MessageFactory", "weblogic.webservice.core.soap.MessageFactoryImpl");
// Setup the global JAX-RPC service factory
System.setProperty( "javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl");
AccessServicePorts ws = new AccessServicePorts_Impl(argv[0]);
AccessService port = ws.getAccessService();
// Resource - create
Resource resource = new Resource();
resource.setRES_CD("Create ResCo");
resource.setCODE_CODE("code_cod");
resource.setRES_TYPE("Resource typ");
resource.setCOMMON_FIELD(common);
AccessDefaultResult resultItems = port.createResource(resource);
System.out.println("createResource : " + resultItems);
I find that this web service client always issue 2 http requests to invoke an web service method deployed in server.
1st http reqeust:
GET /AccessEpol/EpolServiceSoap?WSDL HTTP/1.1
User-Agent: Java/1.4.2_08
Host: 127.0.0.1:8001
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
the return result is the wsdl downloaded from the server.
2nd http request is the real web service request.
The question is how could I eliminate the 1st http request because it's really unnecessary. I use other web service client like Axis 1.x, Axis client never has the http request to download the wsdl from the server.
I read through weblogic web service document. It do mentions that put saveWSDL="true" in the clientgen ant task. the default value for saveWSDL is true already. I did try saveWSDL="false" also. None of them can eliminate the 1st http request.
appreciate for any answer my question?

Hi David,
thanks for the reply.
More or less I agree some points you mentioned above.
I did use Axis 1.x to test the inter-operability. The web service was developed in Weblogic 8.1 and is a part of an existing web application. It will be merged to existing application deployed in weblogic 8.1.
I also program the web service client to test the web service.
The implementation of the server and client will be handed over the project team and training for supporting or continuous development have to be conducted by me. So I don't like to use two types of technologies which will make thing complex.
I found this issue when I tried to protected the web service endpoint, eg http://localhost:7001/epol/service, using the web application Basic mechanism. The wsdl URL http://localhost:7001/epol/service?WSDL is also protected in this case. Unfortunately the username/password pair is not sent to the server when the weblogic client download the WSDL from the server. In this case, the client failed and throw exception.
