Webservice deployment dilemma using weblogic server.

[Guy Emerson]

Hello All,

I am new to webservice .. learning JAX-WS using Weblogic as a middle-ware.

I have seen in examples that there are two ways of deployment :---

1. using Endpoint.publish() method eg..

public class WsPublisher{
 
	public static void main(String[] args) {
	   Endpoint.publish("http://localhost:8888/ws/server", new ServerInfo());
	   
	   System.out.println("Service is published!");
    }

2. using a build.xml file eg..

<project name="webservices-hello_world" default="all">
  <!-- set global properties for this build -->
	<property name="wls.username" value="weblogic" />
	<property name="wls.password" value="weblogic12" />
	<property name="wls.hostname" value="localhost" />
	<property name="wls.port" value="7001" />
	<property name="wls.server.name" value="myManagedServer" />
	<property name="wls.server.port" value="7003" />
	<property name="ear.deployed.name" value="helloWorldEar" />
	<property name="example-output" value="output" />
	<property name="ear-dir" value="${example-output}/helloWorldEar" />
	<property name="clientclass-dir" value="${example-output}/clientclasses" />
	<path id="client.class.path">
		<pathelement path="${clientclass-dir}"/>
		<pathelement path="${java.class.path}"/>
	</path>
	<taskdef name="jwsc" classname="weblogic.wsee.tools.anttasks.JwscTask" />
	<taskdef name="clientgen" classname="weblogic.wsee.tools.anttasks.ClientGenTask" />
	<taskdef name="wldeploy" classname="weblogic.ant.taskdefs.management.WLDeploy"/>
	<target name="all" depends="clean,build-service,deploy,client" />
	<target name="clean" depends="undeploy">
		<delete dir="${example-output}"/>
	</target>
	<target name="build-service">
		<jwsc srcdir="src" destdir="${ear-dir}">
			<jws file="examples/webservices/hello_world/HelloWorldImpl.java" type="JAXWS"/>
		</jwsc>
	</target>
	<target name="deploy">
		<wldeploy action="deploy" name="${ear.deployed.name}" source="${ear-dir}" user="${wls.username}" password="${wls.password}" verbose="true" adminurl="t3://${wls.hostname}:${wls.port}" targets="${wls.server.name}" />
	</target>
	<target name="undeploy">
		<wldeploy action="undeploy" name="${ear.deployed.name}" failonerror="false" user="${wls.username}" password="${wls.password}" verbose="true" adminurl="t3://${wls.hostname}:${wls.port}" targets="${wls.server.name}" />
	</target>
	<target name="client">
		<clientgen wsdl="http://${wls.hostname}:${wls.server.port}/HelloWorldImpl/HelloWorldService?WSDL" destDir="${clientclass-dir}" packageName="examples.webservices.hello_world.client" type="JAXWS"/>
		<javac srcdir="${clientclass-dir}" destdir="${clientclass-dir}" includes="**/*.java"/>
		<javac srcdir="src" destdir="${clientclass-dir}" includes="examples/webservices/hello_world/client/**/*.java"/>
	</target>
	<target name="run">
		<java classname="examples.webservices.hello_world.client.Main" fork="true" failonerror="true">
			<classpath refid="client.class.path"/>
			<arg line="http://${wls.hostname}:${wls.port}/HelloWorldImpl/HelloWorldService" />
		</java>
	</target>
</project>

I want to know if we can use Endpoint.publish() for realtime projects.. What is the compelling reason to use this method of deployment why is better or worse to use Endpoint.publish over deployment through a build.xml script.


Is there another way of deployment by creating a war/ear file and then deploying it using the weblogic console

Is there a server independent deployment technique so that if I move the webservice code from one server to the other I dont have to follow server specific deployment processes as given in the above build.xml spefic for weblogic server



I have been surfing through many examples and articles in google.. but could not find a coherent answer to my questions... If I am being naive please excuse me but I need to clear these doubtful niggles that are pinching my comprehension of the Webservice concept..
