You can upload and download files without any dll or other.
Just use CCS Upload component.
And if you have any wxpirience with java you can create own servlets for upload or download if you need something special.

hi..
i have tried this code..
<!-- upload.jsp -->
<%@ page import="java.io.*" %>
<%String contentType = request.getContentType();
String file = "";
String saveFile = "";
FileOutputStream fileOut = null;
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
{
DataInputStream in = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();
byte dataBytes[] = new byte[formDataLength];
int byteRead = 0;
int totalBytesRead = 0;
while (totalBytesRead < formDataLength)
{
byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
totalBytesRead += byteRead;
}
try {
file = new String(dataBytes);
saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("/") + 1,saveFile.indexOf("\""));
int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1,contentType.length());
int pos;
pos = file.indexOf("filename=/" + 1);
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
int boundaryLocation = file.indexOf(boundary, pos) - 4;
int startPos = ((file.substring(0, pos)).getBytes()).length;
int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;
String folder = "/tmp/";
fileOut = new FileOutputStream(folder + saveFile);
//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
out.println("FileUploaded Succefully");
fileOut.flush(); } catch(Exception e) { out.print(e);
} finally
{ try
{fileOut.close();
}catch(Exception err)

1. Upload nad download it's 2 different processes.
2. For upload some file you don't need any custom or written manually code. Just use fileUpload component.
3. For donload from server you should adjust tomcat for this or use servlet which return file.

Not CSS but CCS.
If you are not a CCS user, I suggest posting your Java questions
on one of the many Java forums.
This is a forum for CCS CodeCharge Studio Users using the Java flavour.

The above file upload can be also done as
// Hi Fnds,
//This is the Simple Code that works well to upload any File Checkout
//Html Code for Browsing Purpose
<html>
<head>
<form action="NewUpload.jsp" name="upform" enctype="multipart/form-data">
<table width="60%" border="0" cellspacing="1" cellpadding="1" align="center" class="style1">
<tr>
<td align="left"><b>Select a file to upload :</b></td>
</tr>
<tr>
<td align="left">
<input type="file" name="filename" size="50">
</td>
</tr>
<tr>
<td align="left">
<input type="hidden" name="todo" value="upload">
<input type="submit" name="Submit" value="Upload">
<input type="reset" name="Reset" value="Cancel">
</td>
</tr>
</table>
</form>
</body>
</html>
//**************************************************************************//
// this is the JSP Code//
<%@ page import="java.util.*,java.io.*"%>
<%
String path=request.getParameter("filename");
String newPath="";
int count=0;
if(path!=null)
{
ArrayList arr=new ArrayList();
StringTokenizer st=new StringTokenizer(path,"\\");
while(st.hasMoreTokens())
{
arr.add(count,st.nextToken());
count++;
}
// create ur own path
newPath="c:/Ravii/"+arr.get(count-1);
int c;
FileInputStream fis=new FileInputStream(path);
FileOutputStream fos=new FileOutputStream(newPath);
while((c=fis.read())!=-1)
{
fos.write((char)c);
}
}
out.println("Thanks for using");
out.println("<br>");
out.println("<br>");
out.println("1.File1 Uploaded from :: "+path);
out.println("<br>");
out.println("<br>");
out.println("2.Uploaded File1 is Saved in :: "+newPath);
%>
Regards,
Senthil

You could try JSP Upload script sample at:
http://www.jfileupload.com/products/tools/index.html
If HTML form upload doesn't fit to your need then you could try an upload applet named JFileUpload. It could also work with the same JSP upload script:
http://www.jfileupload.com/products/jfileupload/index.html
I hope it helps.
