Hmmm...could it be that you are (incorrectly?) instantiating the
BusFactory twice, and it is failing on the second attempt?

I also tried using this:
<code>
Service service = Service.create(SERVICE_NAME);
String endpointAddress =
EDocDocumentumPluginParam.EDocDocumentumPluginParam_EndpointAddress;
service.addPort(PORT_NAME, SOAPBinding.SOAP12HTTP_BINDING,
endpointAddress);
_myPort = service.getPort(MyRequest.class);
</code>
instead of:
<code>
MyService ss = new MyService(wsdlURL,SERVICE_NAME);
_myPort = ss.getMyServicePort();
</code>
To get a reference on the port and I still have the same problem...Calling
several times one service is ok, but callin a service then another one leads
to the same ClassCastException...:-/

Hi!
This morning, I've tried putting the initialization stuff in an
initialization methode which is called only one. And I still have the same
problem...
I will try to do what you're tellin later...
Thanks.

Re: Problems calling 2 different web services from the same Eclipse

Posted by Glen Mazza <gl...@verizon.net>.
BTW, may I ask, why do you need a different wsdl "each time"? As far as
I can see you just need two WSDLs, one for each service. If it is
because the endpoint changes, you can change the endpoint URL
programmatically--see Step #7 here[1].
Also, you said you are calling a different web service from two
different places. What happens if you call the *same* web service from
those two different places--does it work then or break? If the latter,
the fact that you are calling two different services may be just an
irrelevant distraction to finding the real problem.
What we will probably need from you next is a very simple one-class Java
application that iteratively asks a user if they want to call web
service #1 or #2, and then have two methods, one that calls each web
service. Use the CXF samples in the /samples directory for web services
to call (call "ant server" on two of our web services). If you can get
this program to work, that would mean the problem is somewhere else. If
you cannot get the simple program to work, then send the program to us
in a JIRA report--it would be easier to then duplicate and then hunt
down the problem.

I can call the same service 10 times, so I don't think it could come from
that...The problem only comes when I call one service, the another one...
On top of that, I'm currently doing tests to use CXF, and I need to be able
to call the service with a different wsdl each time (I have to test the same

I would try to put your port and service initialization in a constructor
or initialize() method or similar--so it is only done once. Presently
you are initializing these variables with every web service call, which
would be slow anyway. Let us know if that worked.

I don't know but I don't handle myself the BusFatory instanciation.
I just have a client in each of my plugins which looks like the clients CXF
generates automatically:
<code>
String wsdlUrl = "my wsdl path";
File wsdlFile = new File(wsdlUrl);
try {
if (wsdlFile.exists()) {
wsdlURL = wsdlFile.toURL();
} else {
wsdlURL = new URL(wsdlUrl);
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
System.out.println("Using WSDL: " + wsdlURL);
MyRequestService ss = new MyRequestService(wsdlURL,
SERVICE_NAME);
MyRequest port = ss.getMyRequestPort();
// Uses the Web Service:
//
//Then, calls the method of port
</code>
