　　在做单元测试出现这个问题
　　在网上查找原因如下：
　　


這個問題是在解析xml時出現的問題,很明顯,是parser不支持schema,只支持低版本的dtd,兩種可能性,一種你使用的是只支持dtd解析的parser,另一種就是,你的類路徑中包含了不同版本的xml-api或parser,比如:你使用的是j2ee1.4的xml-api,而又在類路徑中加入了xerces.jar
具體的情況可能不同,你分析一下自己引入的jar
　　解决：
　　


确实是在jar包引入上重复了，:你使用的是j2ee1.4的xml-api,而又在類路徑中加入了xerces.jar
在eclipse中我将xerces.jar 上移到xmp-api上面，可能原先的xml-api 版本不对造成
