Question

我正在使用JEE6和Glassfish 3.1以及Eclipse helios。我一直用数据库运行几个EJB，servlet和JPA。现在我只是尝试创建另一个EJB @Statless和@LocalBean。当我将这个bean注入另一个bean以便我可以从那里调用它时，我会遇到部署错误。

并且

最后：

Caused by: javax.naming.NamingException: Exception resolving Ejb for 'Remote ejb-ref name=com.logic.bean/tclient,Remote 3.x interface =com.thrift.ThriftClient,ejb-link=null,lookup=,mappedName=,jndi-name=com.thrift.ThriftClient,refType=Session' .

    at com.sun.enterprise.container.common.impl.ComponentEnvManagerImpl$EjbReferenceProxy.create(ComponentEnvManagerImpl.java:1106)

这是新的EJB代码：

...imports...
@Stateless
@LocalBean
public class ThriftClient {


public ThriftClient(){}

...other code....

以及我如何注射它：

@EJB ThriftClient tclient;

我将它注入到另一个无状态bean中，该bean具有其他可用的EJB注入。

检查Glassfish控制台是否正确部署了bean并使用了什么JNDI名称。我知道它应该开箱即用，但也许值得玩@EJB注释参数使它指向正确的JNDI名称。这可以帮助您找到真正的问题，因为它与JNDI命名明显相关。您也可以尝试通过显式JNDI查找来查找bean而不是注入它，然后您可能会注意到问题。

尝试将一个EJB注入另一个EJB后，CreateException和NamingException
