本文主要介绍如何Xdoclet标注开发EJB，以及如何发布到weblogic。
如何发布WAR，EAR到weblogic。
新建一个java文件，EJB的bean文件，如下，标注为蓝色的为xdoclet注解，会用了生成ejb的descriptor文件。
具体可参考xdoclet文档。
package com.bt.presentation.demo.ejb;
/**
* @ejb:bean type="Stateless" name="com.bt.presentation.demo.ejb.EJBDemo"
* jndi-name="ejb/ejbdemo" display-name="EJB global transaction demo"
*/
public class EJBDemoBean implements SessionBean {
private static final boolean VERBOSE = true;
private SessionContext ctx;
private void log(String s) {
if (VERBOSE)
System.out.println(s);
}
public void ejbActivate() {
log("ejbActivate called");
}
public void ejbRemove() {
log("ejbRemove called");
}
public void ejbPassivate() {
log("ejbPassivate called");
}
public void setSessionContext(SessionContext ctx) {
log("setSessionContext called");
this.ctx = ctx;
}
public void ejbCreate() throws CreateException {
log("ejbCreate called");
}
/**
* @ejb:interface-method view-type="both"
* @ejb:transaction type="Required"
*/
public void testRef(DataStr data) {
System.out.println("testRef Started.");
data.setStr("testRef");
}
}
准备一个application.xml文件如下。
<?xml version="1.0" encoding="UTF-8"?>
<application id="Application_ID" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd">
<display-name>PresentationDemoEAR</display-name>
<module>
<ejb>PresentationDemoEJB.jar</ejb>
</module>
<module>
<web>
<web-uri>PresentationDemoWeb.war</web-uri>
<context-root>PresentationDemoWeb</context-root>
</web>
</module>
</application>
准备一个build.properties，如下：
#set property
WL_HOME=C:/bea/weblogic92
PORT=7001
DEVELOPMENTSERVER=t3://localhost:7001
DEVELOPMENTUSER=weblogic
DEVELOPMENTUSERPASSWORD=weblogic
准备一个build.xml,如下：

<property name="util.src.dir" value="D:/JAVAWorkspace/Test/PresentationUtil/src" />

上面的ejb.src.dir，web.src.dir根据你自己的情况调整，application.xml，build.properties，build.xml放在同一个文件夹下。
