從同事那裡學到一種方便的註解SessionBean的方式。程式碼我放到github去了 https://github.com/EdisonXu/Test/commit/703d49123dca9e666269771b08cc45dea6bff616 或者直接看路徑 https://github.com/EdisonXu/Test/tree/master/remote-bean-test其中test-local雖然打成了可執行jar包，但是依然無法直接通過Java -jar去執行。因為缺乏jboss相關依賴的包。我在網上沒找到dependency，所以懶得搞了。直接把本地JBoss的包配到buildPath了，直接在eclipse中執行。關鍵有兩點：1. 定義一個interface檔案：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{}}這樣在注入的時候直接@EJBRemoteTest.Local localRemoteTest;或者@EJBRemoteTest.Remote RemoteTest;值得注意的是，如果這裡直接用 RemoteTest 去作為型別，在載入這個包時會報錯，會提示定義的RemoteTest.NAME的值，即Test/RemoteTest不唯一。導致部署失敗。2. 方便的JNDI Lookupejb3.1支援的幾種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，但有時候我們會在包名裡面包含版本號，這樣每次修改都要去改原始碼，很不方便。而用上面提供的REMOTE/LOCAL繫結方式，現在直接用RemoteTest rt = (RemoteTest)ctx.lookup(RemoteTest.JNDI_NAME);方便快捷。另外，還有一種方式是在jar包裡面新增ejb-jar.xml。裡面顯示的把去掉版本後的包名或別名寫到 <moduleName>中去。這樣用包名或別名替換掉原來帶版本號的包名就行了。
