weblogic 9下,把stateless session bean发布为web services

假设我已经把EJB做好了，是一个HelloWorld，下面说如何发布 Bean文件如下:

 

package han.ejb;

 

import java.rmi.RemoteException;

import javax.ejb.EJBException;

import javax.ejb.SessionBean;

import javax.ejb.SessionContext;

import javax.ejb.CreateException;

/**

 * XDoclet-based session bean. The class must be declared

 * public according to the EJB specification.

 *

 * To generate the EJB related files to this EJB:

 *           - Add Standard EJB module to XDoclet project properties

 *           - Customize XDoclet configuration for your appserver

 *           - Run XDoclet

 * Below are the xdoclet-related tags needed for this EJB.

 * @ejb.bean name="HelloWorldBean"

 *           display-name="HelloWorld"

 *           description="Description for HelloWorld"

 *           jndi-name="ejb/HelloWorld"

 *           remote="HelloWorldRemote"

 *           type="Stateless"

 *           view-type="remote"

 */

public class HelloWorldBean implements SessionBean {

       private static final long serialVersionUID = 1L;

       public HelloWorldBean() {

              // TODO Auto-generated constructor stub

       }

       public void ejbActivate() throws EJBException, RemoteException {

              // TODO Auto-generated method stub

       }

       public void ejbPassivate() throws EJBException, RemoteException {

              // TODO Auto-generated method stub

       }

       public void ejbRemove() throws EJBException, RemoteException {

              // TODO Auto-generated method stub

       }

       /**

        * Set the associated session context. The container calls this method

        * after the instance creation.

        *

        * The enterprise bean instance should store the reference to the context

        * object in an instance variable.

        *

        * This method is called with no transaction context.

        *

        * @throws EJBException Thrown if method fails due to system-level error.

        */

       public void setSessionContext(SessionContext newContext)

              throws EJBException {

       }

       /**

        * An ejbCreate method as required by the EJB specification.

        *

        * The container calls the instance?s <code>ejbCreate</code> method whose

        * signature matches the signature of the <code>create</code> method invoked

        * by the client. The input parameters sent from the client are passed to

        * the <code>ejbCreate</code> method. Each session bean class must have at

        * least one <code>ejbCreate</code> method. The number and signatures

        * of a session bean?s <code>create</code> methods are specific to each

        * session bean class.

        *

        * @throws CreateException Thrown if method fails due to system-level error.

        *

        * @ejb.create-method

        *

        */

       public void ejbCreate() throws CreateException {

              // TODO Add ejbCreate method implementation

       }

       /**

        * An example business method

        *

        * @ejb.interface-method view-type = "remote"

        *

        * @throws EJBException Thrown if method fails due to system-level error.

        */

       @RemoteMethod()

       @WebMethod()

       public String sayhello() throws EJBException {

              // rename and start putting your business logic here

              return new String("Hello EJB!");

       }

}

事实上JSR 181是BEA提出的用于加速Web Services开发的一种基于注释驱动的编程模式，并被批准纳入到J2EE 1.5标准。JSR181提供了一种简单的Web Service开发编程模型和标准的编译及部署方式。只需要编写JSR-175风格的注释就可以制定WSDL，消息产生属性，安全认证方式，以及特定的消息头。

1.所以，如果要把SESSION BEAN发布为WEB服务，必须在JDK 1.5下做，安装MyEclipse的话，JDK会自动被升级到1.6,所以要先改回来。

Project->properties->java build path,选中JDK，EDIT

 

从Alternate JRE中选JDK 1.5，注意，如果是自己的JDK，版本一定不能高过BEA带的JDK

 

2.添加注释

@JndiName(remote="han.interfaces.HelloWorldBean")

@WebService(name="HelloWorldPortType",              //端口名

        serviceName="HelloWorldService",              //服务名

        targetNamespace="http://ejb.han")            //WebService注释是必须有的，下面的WLHttpTransport和SOAPBinding是推荐的

@WLHttpTransport(contextPath="Hello_EJB",        

             serviceUri="HelloWorldService",          //http://localhost:7001/contextPath/services/serviceUri?wsdl

             portName="HelloWorldPort")

@SOAPBinding(style=SOAPBinding.Style.DOCUMENT,   //好象都这么写

    use=SOAPBinding.Use.LITERAL,

    parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)

添加业务逻辑注释

    @RemoteMethod()

    @WebMethod()

导入相关包

import weblogic.jws.WLHttpTransport;

import javax.jws.WebMethod;

import javax.jws.WebService;

import javax.jws.soap.SOAPBinding;

import weblogic.ejbgen.JndiName;

import weblogic.ejbgen.RemoteMethod;

import weblogic.jws.WLHttpTransport;

 

3.创建build.xml文件(注释是后写的,所以不符合规范)

<projectname="webservice-HelloWorld"default="all">            //工程（默认的任务是all）

    <propertyname="example-output"value="output"/>          

    <propertyname="ear-dir"value="${example-output}"/>

    <propertyname="src-dir"value="./src"/>

    <taskdefname="jwsc"classname="weblogic.wsee.tools.anttasks.JwscTask"/> //Ant任务

    <targetname="all"depends="clean,build-service"/>            //target:all

    <targetname="clean">                                                         //target:clean

       <deletedir="${example-output}"/>                                    //文件目录

    </target>

    <targetname="build-service"depends="                              //target:build-service

       <jwscsrcdir="${src-dir}"destdir="${ear-dir}">                    //源目录和目标目录

           <module>                                                                     //添加jws文件（可以多个）

              <jwsfile="han/ejb/HelloWorldBean.java"/>               /jws文件（包含注释的文件）

           </module>

       </jwsc>

     </target>

</project>

 

4.Run Ant

 

会发现生成了两个文件（application.xml和weblogic-application.xml）和一个JAR（jws.jar）包

 

5.部署

启动服务器，进入console，手动部署

 

处于ACTIVE状态

然后写个客户断就可以测试了
