我是EJB和Geronimo服务器的新手。 我想在Geronimo Server上为EJB创建Junit POC。 但是在向无状态会话bean进行查找时，它给了我这个错误。
请在下面找到例外情况
javax.naming.NamingException: Cannot lookup '/MyStatelessSessionBeanRemote'. [Root exception is java.rmi.RemoteException: Cannot read the response from the server. The class for an object being returned is not located in this system:; nested exception is:
java.lang.ClassNotFoundException: sampleear.RemoteBusinessInterface]
at org.apache.openejb.client.JNDIContext.lookup(JNDIContext.java:240)
at javax.naming.InitialContext.lookup(InitialContext.java:363)
at test.SampleTest.setUp(SampleTest.java:44)
at junit.framework.TestSuite.runTest(TestSuite.java:208)
我正在使用Geronimo服务器2.1，并且还在geronimo服务器中部署了EAR文件。 EAR文件已成功部署，显示在Geronimo服务器上。
请在下面找到日志
