错误原因： 

认为是由于jdk1.5 与 tomcat5.0之间的关于 TransformerFactoryImpl
 类的冲突造成的。

tomcat-5.0.28/common/endorsed下有两个jar包：xercesImpl.jar和xml-apis.jar，其中的类 javax.xml.transform.TransformerFactory 与jdk1.5中的类org
.apache
.xalan
.processor
.TransformerFactoryImpl
其实是同一个类。

in tomcat java
 is called with the following argument:

-Djava.endorsed.dirs="X:/my_app/Portal/tomcat/common/endorsed"

In this directory you find two jar files: xercesImpl.jar and xml-apis.jar needed by tomcat and that must be loaded before all xmsl stuff present in the jdk (1.4 naming problem). And in the file xml-apis.jar the TransformerFactoryImpl
 is set to "org
.apache
.xalan
.processor
.TransformerFactoryImpl
".





解决办法：

1. 将xml-apis.jar移出endorsed文件夹。

2. 用xalan
系列jar包替换原来的xercesImpl.jar和xml-apis.jar。

   xalan
系列jar包：serializer.jar、xalan
.jar、xercesImpl.jar和xml-apis.jar。

3. For other application, just check this file or dom3-xml-apis.jar in your class path.





如果你不会这样做，就使用1.4的JDK和tomcat5.0

或者JDK1.5 tomcat5.5 这2种类型才是匹配的
