　　拿直原始的武器来解决原始的问题：）

一、找这个类antlr.CommonToken
F:\>java -cp . JarClassFind D:\BEA\WebLogic81 antlr.CommonToken
Find class [antlr.CommonToken] in Path [D:\BEA\WebLogic81] Results:
No.1
Jar Package:D:\BEA\WebLogic81\server\lib\weblogic.jar
antlr/CommonToken.class
Find Process Ended! Total Results:1

2、分析配置文件
由于我在weblogic.xml里设置前加载
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

而且我的WEB-INF\lib\下有antlr-2.7.6rc1.jar的包，于是冲突了！导致ClassCastException

三、解决方法：
1、去掉前加载的配置；
2、去掉应用WEB-INF\lib\下的包含antlr.CommonToken类的antlr-2.7.6rc1.jar的包
