Chapter 36. Web Service Interoperability between JOnAS and BEA WebLogic 259
36.2.2.1. Generation of Web Service Client Class
To access the web service, generate the client class using the Ant task
clientgen
. For example:
clientgen wsdl=" wsdl_url " packageName="my.package"
clientJar="client.jar" generatePublicFields="True"
keep generated="True"/
This command creates four classes:
•
Service implementation
•
Java interface
•
Stub class
•
Service interface to the corresponding web service.
The tool can also generate the Java classes corresponding to future complex types of web services.
36.2.2.2. Build the EJB
Then, call the web service in the EJB proxy code using the generated classes. For example:
try {
WSNAME_Impl tsl=new WSNAME_Impl(); // access web service impl
EJB_endpoint tsp = tsl.getEJB_endpoint();
// access WS endpoint interface
ComplexType tr=tsp.method(param);
} catch (Exception e) {
e.printStackTrace(System.err);
};
36.2.2.3. Deploy the EJB on WebLogic Server
Deploy this EJB using the WebLogic administration console.
36.3. Accessing a WebLogic Web Service from a JOnAS EJB
36.3.1. Web Service Development for WebLogic Server
36.3.1.1. Creation of an Application
To create a web service, first develop the corresponding EJB application. Compile the EJB classes and
create a JAR file. To create the EJB’s container, apply the ant task
wlappc
to the JAR file. For example:
wlappc debug="${debug}" source="interface_ws_jonas.jar"
classpath="{java.class.path}:interface_ws_jonas.jar"
Then, use the ant task servicegen to create the ear application containing the web service.
