将项目从tomcat 迁移到JBoss5.0

http://java-boy.iteye.com/blog/531411从Tomcat升级到JBoss5.1真是一个痛苦的过程，可能遇到很多问题。以下是我碰到的问题，及解决方法。

一.Hibernate不兼容问题。

JBoss5.1中内置了hibernate，以前4.x的时候还是在server/default/lib里，但在JBoss5.1的时候已经升级到了common/lib下面。4.x时我直接删掉hibernate等的jar就可以了，但5.1不行，否则会抛很多错误。只能一步步解决。

我首先碰到的问题是hibernate配置文件名字错误，可笑是吗？在JBoss5.1下会首先搜索*-hibernate.xml的文件。如果有就当成jboss hibernate配置的文件，进行加载。而我的项目里的spring下的hibernate配置文件正使用了该结尾，可想而知了。抛出 is in error due to the following reason(s): java.lang.ClassCastException错误。找了好久才找到原因。改一下名字就可以了，如 *-forhibernate.xml

之后是ClassLoad问题。解决上一个问题后，碰到如下异常。
