配置了spring的java application启动出错

今天启动CSS的后台服务CssServer的时候，出现以下错误：

to be solved….

--------------------------

一小时后被我搞定，通过把JAXP相关的jar包在classpath中的order提前，包括XercesImpl.jar,Xalan.jar,xml-api.jar。

之前我并不理解crimson的用途，经过google让我有了一些了解。对自己的环境我能确定的是所有的jar包都有了，而且原先包含这些jar都是能正确运行的，也就没有必要删除多余的jar，后来在google上搜到一个给了我帮助的帖子，上面说到“Jaxp只是个接口（规范），实际的实现是在Xerces或Crimson"，同时，“Crimson继承自Tr－X项目，性能太差，确已快淘汰，但未包含在Xerces中”，我的classpath没有crimson包（这里还有一点疑点，为什么会去找crimson？），但我想到把Xerces往前移应该就解决问题了。果然。

感谢google！        2010-02-22 22：30
