应该是驱动的问题 我的数据库版本是db2 8.1 哪位大侠遇到这样的问题怎么解决的 麻烦告知

------解决方案--------------------
was的jdk是1.4的 1.5的帮不起来 要不然升级jdk配环境变量或升级was到版本7
------解决方案--------------------
应该是jdk版本的问题；
websphere6.0支持jdk1.4,
6.1支持jdk1.5，
7.0支持1.6


------解决方案--------------------
你用jdk1.5编译出来的class文件，怎么能到jdk1.4上执行呢。修过环境变量，把path中的jdk.15对应的路径放在最前面。
------解决方案--------------------
这样的问题通常能在 ibm.com 上找到:
