--  建议你打开 enable-call-by-reference 开关，优化应用程序性能，可以忽略

第二句："EJBModuleDemo.jar": WARNING: Warning from ejbc: <jndi-name> must be defined for a bean with remote interface. 'Student(Jar: C:\DOCUME~1\TianTeng\LOCALS~1\Temp\appcgen)' does not have a remote interface.

-- 建议你将Student这个bean定义一个jndi-name，可以忽略

第三句："EJBModuleDemo.jar": [J2EE:160127]ERROR: Could not delete previous archive: E:\JBuildWordSpace\FrameDemo\EJBModuleDemo.jar

检查下 E:\JBuildWordSpace\FrameDemo\EJBModuleDemo.jar  这个文件看看为啥不能删除，或者将工程clean一下

第四句："EJBModuleDemo.jar": WebLogic APPC tool invocation errors.

-- 这一句是上一句报错导致的，不用管
