struts2 on gae java.lang.IncompatibleClassChangeError

来源:互联网 

It works good in eclipse with gae plugin, but when deploy to gae, I got the following exception.

它在使用gae插件的eclipse中运行良好,但是当部署到gae时,我得到以下异常。

I found there is a similar problem which happens in jersey, asm3.1 works against asm4.0, so I change datanucleus version to 1.x, and remove asm4.0.jar, but it still does not works...

我发现有一个类似的问题发生在球衣上,asm3.1对asm4.0有效,所以我将datanucleus版本更改为1.x,并删除asm4.0.jar,但它仍然不起作用...
