JavaEE@ejb vs@资源

Question

我有一个关于JavaEE bean的问题。我已经用Spring和Hibernate开发了很长时间，现在我改用JavaEE-所以很抱歉，如果这是一个非常简单的问题，但目前我不知道如何处理我的问题。

我有两个bean，它们在JNDI中注册（在JBoss上--参见上面）。-到目前为止还可以。如果我在Servlet中使用@ejb作为依赖项注入，它工作得很好：

@EJB(name = "jndi/TestClassBean")
public TestClass testClass;
@EJB(name = "jndi/OtherBean")
public OtherBean otherBean;

@Resource(name = "jndi/TestClassBean")
public TestClass testClass;
@Resource(name = "jndi/OtherBean")
public OtherBean otherBean;

java:module/OtherBean!at.....test.OtherBeanLocal
java:global/...-javaeetest-frontend/OtherBean!at.....test.OtherBean
java:app/...-javaeetest-frontend/OtherBean!at.....test.OtherBean
java:module/OtherBean!at.maxqu.test.OtherBean

尝试使用查找:

@Resource(lookup = "java:global/...-javaeetest-frontend/TestClassBean!at.....javaeesimpletest.TestClass")
public TestClass testClass;

@Resource(lookup = "java:global/salzburgag-javaeetest-frontend/OtherBean!at.maxqu.test.OtherBeanLocal")
public OtherBean otherBean;
