Use the version of

provided with WebLogic Server.
36.3.1.2. WebService Deployment
Deploy the webservice using the WebLogic administration console, and deploy the corresponding
application.
The WSDL is accessible at
http:// host : port /webservice/web_services?WSDL
36.3.2. EJB Proxy Development for JOnAS
This EJB provides access to the web service deployed on WebLogic from JOnAS.
36.3.2.1. Generation of Web Service Client Class
To access a web service, generate a client class using the Axis tool WSDL2Java webservice-url-
wsdl . This command creates four classes:
•
WSNAME_Locator.java: Service implementation
•
WSNAME_Port.java: Java Interface
•
WSNAME_PortStub.java: Stub class
•
WSNAME.java: Service interface to the corresponding web service.
The tool can also generate the Java classes corresponding to future complex types of web services.
36.3.2.2. Build the EJB
Then, use this generated class to call the web service in the EJB proxy code. For example:
try {
WSNAMELocator tsl=new WSNAMELocator();
WSNAMEPort tsp = tsl.getWSNAMEPort();
ComplexType tr=tsp.method(param);
...
} catch (Exception e) {
e.printStackTrace(System.err);
};
