我在这里遇到了EJB3的怪异问题。已部署EJB3,并且正在尝试从已部署实例访问业务方法。
执行查询时出现以下错误:


UserAuthenticationRemote是远程i / face
UserAuthenticationBean是Bean


代码(失败):

UserAuthenticationRemote remoteInterface = (UserAuthenticationRemote) context.lookup("UserAuthenticationBean/remote");


错误日志:

最佳答案

问题仅在于jar文件。因此,请删除您所投影的所有jar文件格式,然后从jboss-6.0.0.Final \ client文件夹中获取jar文件,这是您正在运行的服务器,并将其作为类路径放置,那么它将正常运行
