为什么我的实体bean发布总失败啊!高分求救!

[dennis03]

俺跟着吴其庆编写的<<J2EE编程思想与实践>>学习实体bean,生成jar和ear都没有问题,在weblogic7上布署ear时就报错,而布署书中示例ear就正常发布使用，晕死我了,对比了源程序和所有xml源文件都相同,就是布署自已编写的EJB就会失败,我用的是JBuilder9,请各位大佬鼎力相助啊!问题解决即结贴!


以下是发布时weblogic的报错提示:

我发现JBuilder9根本就不能编实体bean,我改用JBuilderX后就可以正常编实体bean,并将ear文件正常在weblogic7中布署,可是客户端程序又报告下面错误,我现在觉得JBuilder真是一个鸡肋!

你可以配置JB9和WB7一起用啊，很方便的。
JB中TOOLS菜单中可以配置服务器的

经过我的不断测试,终于发现问题的所在,用JBuilder9开发了bmp后,编译生成jar文件,用winrar解压后,发现形成ejb的三个主要class文件不能反编译,其它文件大小和内容与随书附例则完全一至,所以问题最终定位在为什么JBuilder9编译的实体bean三个主要class文件为什么坏了,这也是导至weblogic7发布jar或ear最终失败的原因.
于是我尝试解决问题,先将原书<<J2EE编程思想与实践>>中的关于bmp示例用JBuilder9打开,将ejb打包成jar文件,再解压反编译,全部正常,证明原例在JBuilder9中是正常的,将ejb的三个文件的原文件内容粘贴覆盖自已编写的ejb的三个java文件,保存后重编译打包,再解压反编译,三个主class文件依然不能反编译,目前我还没找到问题的原因所在,是JBuilder9的一个bug还是另有其他编译前的隐秘设置我不清楚,希望JBuilder高手们出手帮助,我现在也在解决中,相信这一问题的解决会使一大批从JBuilder开始学习bmp而倒下的人重新站立起来!

[dennis03]

问题已解决,JBuilder9在编译bmp时生成的class文件的确有问题,<<J2EE编程思想与实践>>这本书中的例子是用JBuilder8编写的,所以大家还是不要用JBuilder9了,用JBuilderX吧!
同时谢谢orant(仗剑走天涯) 的回复,虽然不能解决问题,但有回复总比没回复强,所以这100分全给你了!
