我定义了一个EJB,我试图在另一场战争中使用它:
在ejb-api.jar
:
@Remote
public interface Example {
// ...
}
在ejb-impl.war
中(使用ejb-api.jar
):
@Stateless(mappedName = "ExampleEjb")
public class ExampleBean implements Example {
// ...
}
在ejb-user.war
中(使用ejb-api.jar
):
@WebServlet("/ejbuser")
public class UserServlet extends HttpServlet {
@Override
public void doGet(...) throws Exception {
Example example = null;
try {
InitialContext context = new InitialContext();
example = (Example)context.lookup("ExampleEjb");
} catch (NamingException e) {
e.printStackTrace();
}
}
}
我将ejb-impl.war
和ejb-user.war
部署到JBoss AS 7.1的实例中。
如果我将所有类放在同一个war文件中,那么就找到了EJB。但是这样,它不是(我得到NamingException
)。
此外,如果我添加一个包含这些内容的jndi.properties
文件......
java.naming.factory.initial = org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url = remote://localhost:4447
jboss.naming.client.ejb.context = true
java.naming.factory.url.pkgs = org.jboss.ejb.client.naming
...然后我收到了这样的警告:

你知道我做错了吗?
答案 0 :(得分:4)
根据@Stateless' documentation,“应用服务器不需要支持任何特定形式或类型的映射名称,也不需要使用映射名称。”因此,使用它来更改bean的映射名称IMHO不是一个好主意。
我们试试
java:global[/application name]/module name/enterprise bean name[/interface name]

<强>编辑:强> 您将两个模块部署到同一个应用服务器,不是吗?然后,您不需要jndi.properties文件,让我们尝试不使用它。
