Hello

Try to assign the contents of your form parameters to variables...

Code:

<%@ page import="java.util.Map"%>
<%
Map params = request.getParameterMap();
String userName = "";
String fileName = "";
try{
  userName = ((String[])params.get("username"))[0];
}catch(Exception e){}
try{
  fileName = ((String[])params.get("filename"))[0];
}catch(Exception e){}
%>

...and include these variables again in your page:

Code:

username=<%=userName%>, filename=<%=fileName%>

Here's a complete example:

Code:

<%@ page import="java.util.Map"%>
<%@ page session="false"%>

<%
Map params = request.getParameterMap();
String userName = "";
String fileName = "";
try{
  userName = ((String[])params.get("username"))[0];
}catch(Exception e){}
try{
  fileName = ((String[])params.get("filename"))[0];
}catch(Exception e){}
%>
     <html>
     <head>
     <title>Test</title>
     </head>

     <body>
     <h1>Test</h1>
     <br>
     <form method="post" action="test.jsp">
     <table>
	     <tr><td> 
	     Username:
	     </td><td>
	     <input name="username" type="text" style="width:400;"/>
	     </td></tr>
	     
	     <tr><td> 
	     Filename:
	     </td><td>
	     <input name="filename" type="file" style="width:400;"/>
	     </td></tr>
	
	     <tr><td> 
	     &nbsp;
	     </td><td>
	     <input name="submit" type="submit" value="Submit"/>
	     </td></tr>
	
	     <tr><td> 
	     &nbsp;
	     </td><td>
	     &nbsp;
	     </td></tr>
	
	     <tr><td> 
	     Parameters:
	     </td><td>
	     username=<%=userName%>, filename=<%=fileName%> 
	     </td></tr>
     </table>
     </body>
     </html>
