环境：sun jdk1.5.0_15 + tomcat 5.0.28

原本以为自己玩了eclipse和myeclipse这么多年，一向项目的配置发布用myeclipse虽然没有驾轻就熟，但是至少不会被难道，这次确倒在了这个jdk 1.5及tomcat 5.0.28的环境上。谁叫以前一直没有试过在tomcat5.0.28上发布struts2呢，刚好现在客户说一定要用struts2，刚好自己也想偿偿新，却偿到了这个苦头。开始还以为是自己用myelipse deploy的问题，结果却不是，为啥别人的tomcat5.5就能好好的run呢？废话不少说，现在就看以下exception：

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.

（以上参考小立飞刀的TransformerFactoryImpl not found exception一文，也谢谢作者解答这个难题）
