Class BurlapProxyFactory

java.lang.Object

com.caucho.burlap.client.BurlapProxyFactory

All Implemented Interfaces:

ServiceProxyFactory, ObjectFactory

public class BurlapProxyFactory
extends Object
implements ServiceProxyFactory, ObjectFactory

Factory for creating Burlap client stubs. The returned stub will call the remote object for all methods.

 String url = "http://localhost:8080/ejb/hello";
 HelloHome hello = (HelloHome) factory.create(HelloHome.class, url);
 

After creation, the stub can be like a regular Java class. Because it makes remote calls, it can throw more exceptions than a Java class. In particular, it may throw protocol exceptions. The factory can also be configured as a JNDI resource. The factory expects to parameters: "type" and "url", corresponding to the two arguments to create In Resin 3.0, the above example would be configured as:

 <reference>
   <name>hessian/hello</name>
   <factory>com.caucho.hessian.client.HessianProxyFactory</factory>
   <init url="http://localhost:8080/ejb/hello"/>
         type="test.HelloHome"/>
 </reference>
 

To get the above resource, use JNDI as follows:

 Context ic = new InitialContext();
 HelloHome hello = (HelloHome) ic.lookup("java:comp/env/burlap/hello");

 System.out.println("Hello: " + hello.helloWorld());
 

Authentication

The proxy can use HTTP basic authentication if the user and the password are set.

 String url = "http://localhost:8080/ejb/hello");
 HelloHome hello = (HelloHome) factory.create(HelloHome.class, url);
 

Specified by:

create in interface ServiceProxyFactory

Parameters:

api - the interface the proxy class needs to implement

urlName - the URL where the client object is located.
