Question

请教下jsp上传文件,没有用struts2标签html页面使用 file form有 enctype属性 只要选择文件就报错

<form method=“post” action="uploadaction" enctype="multipart/form-data" >
页面标签<input type="file" name="uploadImg" /> 多文件上传
action:
private File[] uploadImg;
private String[] uploadName;
private String[] uploadImgFileName;
private String[] uploadImgContentType;

struts.xml中也设置了存放文件的临时目录
运行时只要选择了文件 就报错。
报错信息：

注意：form的action 输入错误了 应该是 byishenAction 。不好意思。请问该如何解决此问题？
