jndi 在 jboss4.2.3 和 ejb3 上的绑定
我正在尝试使用 ejb3 注释在 jboss 4.2.3 上部署无状态 ejb。一切都正确构建和部署，并且当 jboss 启动时我没有收到任何错误。然而，当我查看 jboss 中的绑定时，ejb 并未绑定到任何用于查找的 JNDI 位置。下面是我的 ejb 的内容。
远程
@Remote
public interface TestWebService {
public String TestWebMethod(String param1, String param2);
}
无状态 EJB
@Stateless
@RemoteBinding(jndiBinding="TestWeb")
@Remote(TestWebService.class)
public class TestWebServiceBean implements TestWebService{
public String TestWebMethod(String param1, String param2) {
System.out.println("HELLO "+param1+" "+param2);
return "Welcome!!";
}
}
我尝试过不使用 @Remote 和 @RemoteBinding，但没有什么区别。我还添加了 ejb-jar.xml 文件（ejb3 不需要该文件），但这似乎没有什么区别。下面是我在启动时在 jboss 日志中看到的输出。
installing MBean: jboss.j2ee:ear=ejb_web_service_ear-0.0.1- SNAPSHOT.ear,jar=ejb_web_service-0.0.1-SNAPSHOT.jar,name=TestWebServiceBean,service=EJB3 with dependencies:
21:56:00,633 INFO [EJBContainer] STARTED EJB: com.tomax.ejb.TestWebServiceBean ejbName: TestWebServiceBean
I am trying to deploy a stateless ejb on jboss 4.2.3 using ejb3 annotations. Everything builds and deploys correctly, and I do not get any errors when jboss starts up. However the ejb is not getting bound to any JNDI location for lookup when I look at the bindings in jboss. Below is what I have for my ejb.
Remote
@Remote
public interface TestWebService {
public String TestWebMethod(String param1, String param2);
}
Stateless EJB
@Stateless
@RemoteBinding(jndiBinding="TestWeb")
@Remote(TestWebService.class)
public class TestWebServiceBean implements TestWebService{
public String TestWebMethod(String param1, String param2) {
System.out.println("HELLO "+param1+" "+param2);
return "Welcome!!";
}
}
I have tried not having the @Remote and @RemoteBinding and it doesn't make a difference. I have also added and ejb-jar.xml file (which should not be needed with ejb3) and that does not appear to make a difference. Below is the output I see in the jboss log on startup.
installing MBean: jboss.j2ee:ear=ejb_web_service_ear-0.0.1- SNAPSHOT.ear,jar=ejb_web_service-0.0.1-SNAPSHOT.jar,name=TestWebServiceBean,service=EJB3 with dependencies:
21:56:00,633 INFO [EJBContainer] STARTED EJB: com.tomax.ejb.TestWebServiceBean ejbName: TestWebServiceBean

我发现了这一点，所以如果其他人也遇到类似的问题，希望这会有所帮助。首先，我在 jboss 4.2.3 中的注释包不正确，对于这个版本的 jboss，它们应该是 org.jboss.anotation.ejb.*，在 5 及更高版本中，这已经改变了。此外，我的 Ear 文件中还有一些额外的依赖项 jar，这些依赖项不应包含在内，因为它们是由容器提供的。一旦我删除了它们，它就起作用了。
I figured this out, so in case anyone else has similar problems hopefully this will help. First I had the incorrect package for the annotations in jboss 4.2.3, they should be org.jboss.anotation.ejb.* for this version of jboss, in 5 and up this has changed. Also there were some additional dependency jars in my ear file that should not have been included since they are provided by the container. Once I removed those then it worked.
