我有两个文件，一个是jsp文件，第二个是servlet文件。
当我在jsp文件中包含输入文本字段以将文本传递给servlet文件然后作为运行提供错误消息的程序的时间时，为什么会发生这种情况？
index.jsp代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>File Upload</title>
</head>
<body>
<center>
<h1>File Upload</h1>
<form method="post" action="UploadServlet"
enctype="multipart/form-data">
<table border="1">
<tr><td><h3>Input Text at Top of image :</h3> </td><td><input type="text" name="name1" /></td></tr>
<tr><td><h3>Input Text at Bottom of image :</h3> </td><td><input type="text" name="name2" /></td></tr>
</table><br>
Select file to upload: <input type="file" name="file" size="60" /><br />
<br /> <input type="submit" value="Upload" />
</form>
</center>
</body>
</html>
UploadServlet.java servlet文件：

public class UploadServlet extends HttpServlet
{
/**

private static final String SAVE_DIR = "uploadFiles";
/**

HttpServletResponse response) throws ServletException, IOException
{

{

// refines the fileName in case it is an absolute path
fileName = new File(fileName).getName();
part.write(savePath + File.separator + fileName);
}
String text1 = "";
String text2 = "";
text1 = request.getParameter("name1");
text2 = request.getParameter("name2");
request.setAttribute("message", "Upload has been done successfully!"+"<br>"+savePath);
getServletContext().getRequestDispatcher("/message.jsp").forward(
request, response);
}
/**

}
}
return "";

}
如何将从jsp传递给servlet的值传递给text1和text2字符串变量？ 错误附加为图片error after including the html code as follow :
<table border="1">
<tr><td><h3>Input Text at Top of image :</h3> </td><td><input type="text" name="name1" /></td></tr>
<tr><td><h3>Input Text at Bottom of image :</h3> </td><td><input type="text" name="name2" /></td></tr>
</table>
