 晕啊。。。。。。。用2。0的包就没事于是疯狂的Google baidu 结果。。。。。。无

求教很人。。。。结果 呵呵！！！

你注意看struts-default.xml文件里有这么几句

XML code

     />
     
     
     
      
     
     
     
     <

     />
     
     
     
      
    
    
    
    

Caused by: Unable to load bean: type:org.apache.struts2.dispatcher.multipart.MultiPartRequest class:org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequest 就是出在这里，因为加载这个类的时候org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequest 你可以查看这个类的源文件 其中前面有这样几句

在这个类中必须引入org.apache.commons.fileupload.*; 而你也许没有加载这个文件上传包所以找不到类 提示错误java.lang.NoClassDefFoundError: org/apache/commons/fileupload/RequestContext 建议你先导入2个jar文件 文件名为commons-fileupload-1.2.1.jar .jar 和 commons-io-1.3.2.jar
