哦跟ACTION没关系吧
去掉enctype="multipart/form-data" 就正常了

Answer 2

argument type mismatch是什么错误啊？
关注中，帮不上忙，帮你顶一下

Answer 3

这是因为jspSmartUpload上传组件不符合STRUTS标准,所以当你在STRUTS里面调用它时,就会出现以上错误,建议使用STRUTS的上传组件,否则在这个页不要使用STRUTS,直接用JSP就行了

Answer 4

能给个STRUTS的上传组件的例子吗？

Answer 5

action="registerUsersAction.do"，你把action提交页换成一个jsp页试试

}
我换成Struts的编译时出错了！
