I've used the CCS file upload form... are you having a specific problem? I'm using it to upload files for batch processing purposes. The form inserts a record into my database that contains the uploaded file name and a backend Java process wakes up at scheduled times to query the database for new files to process. I can provide more detail or you can have a look at the examples in CCS help.
Regards,
Curtis

You would not want to upload a image into the database.
What if the image is large ?
Also retrieving the image would be a problem too.

Well Friend, I worked on this code successfull ; I hope it will solve your problem too :)
<!-- upload.jsp -->
<%@ page import="java.io.*" %>
<%
String contentType = request.getContentType();
System.out.println("Content type is :: " +contentType);
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;
}
String file = new String(dataBytes);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
//out.print(dataBytes);
int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1,contentType.length());
//out.println(boundary);
int pos;
pos = file.indexOf("filename=\"");
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;
FileOutputStream fileOut = new FileOutputStream(saveFile);
//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();
out.println("File saved as " +saveFile);

Which is the example in codecharge/CSS for usage of FIle Upload (java/jsp)?
I was able to save the filename in the db column using the FIle Upload control in a record form. But when I edit the record, I see the file name as static text with the delete check box besides it. Is there a way i can access the file (probably open it for reading or download it to local space) instead of just seeing the name ? Or am i using it wrong?
Can anyone help with how of if I can use CSS File Upload for doing the above task?

Hai to Every one I have a solution to JSP Insert image into Database
<%-- This jsp Page is Uploding The Image into Database using MultipartRequest class
FileSystem concepts and ByteArray.
--%>
<%@ page import="java.sql.*,java.io.*,java.util.*,com.oreilly.servlet.MultipartRequest,com.microsoft.jdbc.sqlserver.SQLServerDriver;"%>
<%
/* The Following Code is Used To Insert An Image Into Database */
String filename="";
try
{
//Download com.oreilly package
MultipartRequest multi= new MultipartRequest(request,".",5*1024*1024);
Enumeration files=multi.getFileNames();
File f=null;
while(files.hasMoreElements())
{
String name=(String)files.nextElement();
filename=multi.getFilesystemName(name);
String type=multi.getContentType(name);
f=multi.getFile(name);
System.out.println("The File is "+f);
}
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection con = DriverManager.getConnection("jdbc:microsoft:sqlserver;databasename="xxx","username","password");
Statement stmt = con.createStatement();
InputStream is = new FileInputStream(f);
byte b[]=new byte[is.available()];
is.read(b);
String sql = "INSERT into photo_test (\"Photo\") values('" + b + "')";
stmt.execute(sql);
stmt.close();
}catch(Exception e)
{
System.out.println(e);
}
out.println("The Image is Added into Database");
This code is perfectly working , I could store an image into database using this program but i am unable to retrieve the page. The image is getting decoded but when i am trying to send the content to a file and open it, it is giving me the name fo the file but the picture is not getting opened. So any one can help me.
Thanks advans

Hi! I am also looking at loading a file into database. can you guys please assist me with the following questions:
1. What datatype should I have in the database? CLOB or BLOB?
2. How could I use a form post for user to select the file and then use the above code to do the upload?
3. Say if I uploaded a pdf file, any one has example how I could display a pdf icon and when click on it, the acrobat read will be activated?
Thank you.

<input type="submit" name="Submit" value="Submit">
<input type="reset" name="Reset" value="Reset">
