WTC的配置(二)

程序开发

编写WeblogicEJB.java

package org.flying.ejb;

 

import javax.ejb.CreateException;

import javax.ejb.SessionBean;

import javax.ejb.SessionContext;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.naming.NamingException;

 

import weblogic.wtc.jatmi.TPException;

import weblogic.wtc.jatmi.TypedString;

import weblogic.wtc.jatmi.Reply;

import weblogic.wtc.jatmi.TPServiceInformation;

 

public class WeblogicEjb implements SessionBean {

       private static final long serialVersionUID = 1L;

       static final boolean VERBOSE = true;

       private SessionContext ctx;

       /**

        * Sets the session context.

        * @param ctx

        *            SessionContext Context for session

        */

       public void setSessionContext(SessionContext ctx) {

              this.ctx = ctx;

       }

       /**

        * This method is required by the EJB Specification, but is not used by this

        * example.

        *

        */

       public void ejbActivate() {

       }

       /**

        * This method is required by the EJB Specification, but is not used by this

        * example.

        *

        */

       public void ejbPassivate() {

       }

       /**

        * This method is required by the EJB Specification, but is not used by this

        * example.

        *

        */

       public void ejbRemove() {

       }

       public void ejbCreate() throws CreateException {

       }

       public Reply service(TPServiceInformation mydata) throws TPException {

              TypedString data;

              String lowered;

              TypedString return_data;

              data = (TypedString) mydata.getServiceData();

              log("converting " + data);

              lowered = data.toString().toLowerCase();

              log("converted " + data);

              return_data = new TypedString(lowered);

              mydata.setReplyBuffer(return_data);

              return (mydata);

       }

       private void log(String s) {

              if (VERBOSE) {

                     System.out.println(s);

              }

       }

}

EJBHome和Romote接口不用写，稍后处理。

配置ejb-jar.xml

       xmlns:xsi=""

       xsi:schemaLocation=" /ejb-jar_2_1.xsd"

       version="2.1">

      

             

                     TOLOWEREJB

                     weblogic.wtc.jatmi.TuxedoServiceHome

                     weblogic.wtc.jatmi.TuxedoService

                     org.flying.ejb.WeblogicEjb

                     Stateless

                     Container

             

      

      

             

                    

                            TOLOWEREJB

                            *

                    

                     Supports

             

      

重要：配置中和被配置为weblogic.wtc.jatmi.TuxedoServiceHome和weblogic.wtc.jatmi.TuxedoService，这是WTC配置的要求，是他们tuxedo ejb服务的统一入口，所以开发中不用写home和romote接口。

配置weblogic-ejb-jar.xml

       xmlns:j2ee=""

       xmlns:xsi=""

       xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-ejb-jar.xsd">

      

              TOLOWEREJB

             

                    

                            100

                            5

                    

             

             

                     0

             

              true

              TOLOWER

      

程序打包成JAR

使用MyEclipse中的项目导出（Export）功能，将java文件导出成JAR文件EJB.jar。
