关于在Tomcat5中使用jspsmartupload上传文件中的错误

Beiune

我用 Tomcat 5.0.28作为服务,然后使用jspsmartupload来实现文件的上传,开始设置测试成功.但是重新启动服务器后就出问题了,请高手给看一下.

我的负责接收上传的文件jsp 代码是:
<%@ page import ="com.jspsmart.upload.SmartUpload,java.util.*,java.io.*" %>
<%
int count=0;
SmartUpload su = new SmartUpload();
su.initialize(pageContext);
su.upload();
try{
int count=su.save("/upload/");
if (count==1) {out.print("sucess");}
else out.print("Failed");
}
catch(Exception e)
{
out.println(e.toString());
}
out.print("size:"+su.getSize());
%>
