摘要: 在weblogic 8.1上部署EJB时出错，在线等待

Unable to deploy EJB: E:/bea/user_projects/domains/mydomain/applications/okEJB from okEJB:

在weblogic控制台直接到文件目录中去部署
结构出下：
okEJB
--com
--ejb (TradeBean.class,TradeSession.class此类继承前面那个)
--interfaces (TradeLocal.class,TradeLocalHome.class)
--META-INF (ejb-jar.xml,weblogic-ejb-jar.xml)

其中weblogic-ejb-jar.xml内容如下：
<?xml version="1.0" encoding="UTF-8"?>

ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
