从同事那里学到一种方便的注解SessionBean的方式。代码我放到github去了 https://github.com/EdisonXu/Test/commit/703d49123dca9e666269771b08cc45dea6bff616 或者直接看路径 https://github.com/EdisonXu/Test/tree/master/remote-bean-test其中test-local虽然打成了可执行jar包，但是依然无法直接通过Java -jar去执行。因为缺乏jboss相关依赖的包。我在网上没找到dependency，所以懒得搞了。直接把本地JBoss的包配到buildPath了，直接在eclipse中运行。关键有两点：1. 定义一个interface文件：public interface RemoteTest {    public static final String NAME = "Test/RemoteTest";    public static final String JNDI_NAME = "Test/RemoteTest/remote";    public String getTest();    /**     * Local interface for session bean     */    public static interface Local extends RemoteTest{}    /**     * Remote interface for session bean     */    public static interface Remote extends RemoteTest{}}这样在注入的时候直接@EJBRemoteTest.Local localRemoteTest;或者@EJBRemoteTest.Remote RemoteTest;值得注意的是，如果这里直接用 RemoteTest 去作为类型，在加载这个包时会报错，会提示定义的RemoteTest.NAME的值，即Test/RemoteTest不唯一。导致部署失败。2. 方便的JNDI Lookupejb3.1支持的几种JNDI LOOKUP：java:global/Get EJB instance by lookup global in java: Namespace. Syntax:         java:global/<ear-name>/<jar-name>/<bean-name>[!<fully-qualified-interface-name>]  Sample: SampleBean implements SampleBeanRemote interface  SampleBeanRemote {    JNDI_NAME="SampleBean";}sampleBeanInstance =  (SampleBeanRemote)lookupByGlobal(SampleBeanLocal.JNDI_NAME);java:app/Get EJB instance by lookup app in java: Namespace. Note: Only effect when  the expect bean is in the same ear file with the POJO calling this method.  Syntax:         java:app/<jar-name>/<bean-name>[!<fully-qualified-interface-name>]  Sample: SampleBean implements SampleBeanLocal interface  SampleBeanLocal {    NAME="SampleBean";}sampleBeanInstance = (SampleBeanLocal)lookupByApp(SampleBeanLocal.NAME);java:module/Get EJB instance by lookup module in java: Namespace. Note: Only effect  when the expect bean is in the same jar file with the POJO calling this method.  Syntax:         java:module/<bean-name>[!<fully-qualified-interface-name>]  Sample: SampleBean implements SampleBeanLocal SampleBeanLocal  {    NAME="SampleBean";}sampleBeanInstance =  (SampleBeanLocal)lookupByModule(SampleBeanLocal.NAME);其中global, app 需要提供包名，但有时候我们会在包名里面包含版本号，这样每次修改都要去改源代码，很不方便。而用上面提供的REMOTE/LOCAL绑定方式，现在直接用RemoteTest rt = (RemoteTest)ctx.lookup(RemoteTest.JNDI_NAME);方便快捷。另外，还有一种方式是在jar包里面添加ejb-jar.xml。里面显示的把去掉版本后的包名或别名写到 <moduleName>中去。这样用包名或别名替换掉原来带版本号的包名就行了。
