解决 struts2 in tomcat5.0 Error filterstart 问题
struts2 在 tomcat5.0下出现以下错误,而在tomcat5.5下则正常运行。
2008-8-1 11:19:56 org.apache.catalina.core.StandardHostDeployer install 信息: Installing web application at context path /struts2Test from URL file:D:\Tomcat 5.0\webapps\struts2Test2008-8-1 11:20:05 org.apache.catalina.core.StandardContext start 严重: Error filterStart 2008-8-1 11:20:05 org.apache.catalina.core.StandardContext start 严重: Context startup failed due to previous errors

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。
