jsp、servlet上传文件遇到的问题

代码很简单，网上书上都有的，也都对，点击提交后没能正确上传是因为我网址输错了，(￣▽￣")

正确输入方式：http://localhost:8080/Up/UploadFile.jsp

注意：Up是工程名。UploadFile.jsp是提交上传文件的页面。

另外，转移到上传结果页面用到这句：request.getRequestDispatcher("/UploadResult.jsp").forward(request, response);

web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>

<servlet-name>UpServlet</servlet-name>

<servlet-class>com.snp.UpServlet</servlet-class>

<init-param>

<param-name>savePath</param-name>

<param-value>/uploads</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>UpServlet</servlet-name>

<url-pattern>/servlet/upload
</url-pattern>

</servlet-mapping>

</web-app>

相应的UploadFile.jsp中;

<form action="<%=request.getContextPath()%>/servlet/upload
" method="post" enctype="multipart/form-data" name="form1" id="form1">
