java.lang.NoClassDefFoundError: org/apache/xerces/util/EncodingMap

[weimu2002]

这个项目是直接从公司svn上下的，下了后就出现下面的问题了，项目要求是jdk1.5和tomcat5.5，本机装的是1.6版本的，jdk1.5是在eclipse里直接引入的。也在网上查了很多，但是还是不对，我在tomcat里也把关于xerces.jar放到tomcat的lib下了，也尝试在工程里删除重新导入，但是还是不行。求大神指导。忘了补充了，这是2个项目中的其中一个，另外一个部署没问题的，就这个出问题了，所以我认为jdk1.5我应该部署正确了，org.apache.xerces.util.EncodingMap这里有这个包的。

[weimu2002]

造成的原因是tomcat5.5和jdk1.5一起用的结果。需要配置一些文件，比如xerces.jar的问题。

[panzhixiong_cn]

项目编译通过了吗？

哦，不错啊，自己解决了。有没有什么心得可以分享一下给大家啊？

我现在也遇到了tomcat5.5.30与xerces.jar不兼容的问题，jdk是1.5.0.8的，能给个解决方法么？3q。。。
