This is a program to accept the file from user using JSP and then uploads the file into the target server. It uses the jsch api.
You need to download the JSch api and include in the jars.Upload.jsp :
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<center>
<H1> APPLICATION TO PUSH FILES [ SAMS ]</H1>
<form method="post" action="singleFileUpload" enctype="multipart/form-data">
<br>
Select file to upload:
<input type="file" name="uploadFile" />
<br/><br/>
<input type="submit" value="Upload" />
</form>
</center>
</body>
