Accessing non-weblogic SOAP

Question

Hello,
I'm trying to access some simple web services which are implemented using
some Perl module (don't ask ....).
After I've gotten their WSDL file, I can successfully generate stubs using
the clientgen ant task.
However, when I try to access the webservice from within my EJB's, I get the
following error message:
An IOException was thrown trying to access the WSDL at the given URL.
java.io.FileNotFoundException: Response: '411: Length Required' for url:
'http://petest01:8082/cgi-bin/WebStore.cgi'
It seems as if the perl SOAP implementation doesn't allow me to check their
WSDL file. Just sending the SOAP POST messages works fine.
I explicitly specified the 'saveWSDL' option to the clientgen task, but it
still tries to access the WSDL file at runtime. Any way to resolv this
issue?
Regards,
Francois Staes.

Hi Francois,
The JAR file generated by the <clientgen> Ant task, has a static WSDL inside it.
To get your JAX-RPC client to use it, write code that looks like this:
MyService_Impl service = null;
MyServicePort port = null;
try
// There are two constructors for every XXX_Impl class.
// The one that accepts a wsdlURL (as a String) will
// request the WSDL from the service provider. The
// no-arg one will just use the statis WSDL in the
// client.jar generated by the <clientgen> Ant task.
service = new MyService_Impl();
port = service.getMyServicePort();
MyObject response = port.myServiceOperation();
Again, this will cause the WLS client-side JAX-RPC classes, in the webserviceclient.jar,
to use the static WSDL (in the client.jar generated by the <clientgen> Ant task)
to invoke the target web service. It will not send a request to the target web
service to retrieve it's WSDL, because it already has it.
