[200分]求救,急死我了,都弄了好几天了,把Beans部署到JBoss 4

/*******************************************************************************/
问题描述:我装下面的的ejb部署到jboss 4 sp1里,jboss没有出现任何的反溃信息,一般情况下
        部署EJB无论是成功还是失败,JBOSS都会出现一些反溃信息的,可这连个异常也不给
        我抛出客户端测试也不成功,这个问题困扰了我快一个星期.
        救各位帮我看看,是我Beans写错了,还是部署文件写错,或是两者都有错.

部署出问题一般都是配置文件有问题，或者配置文件和类文件不对应。。。光给类文件是没用的

#3

沉了.....

#4

你用的IDE是什么呢？如果是Eclipse和Limboz的话，我有一个例子可以给你看看。

我的问题解决了,原来是键误
原来我是:jar cvf Product.jar examples meta-inf 这样打包的,部署不成功,并且在Jboss上不会显示任何的反溃信息

后来改成:jar cvf Product.jar examples META-INF,这样就成功了

原来编译和打抱的时候也要区分大小写的
