EJB部署出错: Unable to load a class specified in your ejb-jar.xml

摘要: EJB部署出错: Unable to load a class specified in your ejb-jar.xml

如题,我的开发环境是:Eclipse3.12+myEclipse4.0,EJB容器是weblogic server 9.1.在部署EJB时出现错误,具体如下:
激活更改期间出错，有关详细信息，请查看日志。
Exception preparing module: EJBModule(HelloWorld) Unable to deploy EJB: C:/eclipse/workspace/EJBHelloworld/classes/HelloWorld.jar from HelloWorld.jar: Unable to load a class specified in your ejb-jar.xml: exapmleOne.ejb.HelloBean
Substituted for the exception weblogic.ejb.container.deployer.DeploymentDescriptorException which lacks a String contructor, original message - Unable to load a class specified in your ejb-jar.xml: exapmleOne.ejb.HelloBean
请达人请点.另外,我也不太清楚怎么部署EJB,只是通过http://localhost:7001/console在"域结构"下的"部署"那里直接点"安装",不知对不对,请不吝赐教.谢谢!!!

但是里面明明就有那个类,为什么会找不到呢?

---

请问weblogic server 9.1中的EJB配置描述weblogic-ejb-jar.xml中的第二句应该怎么写,如 weblogic-ejb-jar PUBLIC "-//BEA Systems, Inc.//DTD WebLogic 8.1.0 EJB//EN" "wls810_weblogic-ejb-jar.dtd" >这一句在9.1中应该换成什么?
