hi

<%

String url="http:| \\-/ |"+request.getLocalName()+":"+request.getLocalPort()+request.getContextPath()+"/images/";
String contentType = request.getContentType();
System.out.println("444444444444444444 "+url);
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;
//out.println(url);
String demo="http://localhost:8080/challenge/images/200.jpg";
System.out.println("http://localhost:8080/challenge/images/200.jpg");
FileOutputStream fileOut = new FileOutputStream("326.jpg");


//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();

//out.println("File saved as " +saveFile);

Just one question, is your db server the same as your JSP server ?
If not I can't tell you how to do it because the upload happen from the JSP client to the JSP server regardless to the db Server...
