View JPG Image from Servlet File

[Kondal reddy]

how can I show JPG file in my jsp ...that jpg coming in servlet as a File format...if any one know help me.

The same way that you show any other image: with an <img> tag. If the image data is being served up by a servlet, be sure that the src attribute of the tag references the servlet as appropriate.

Hi bear thanq for responding ...actually my servlet getting like this :



FTPFile[] files = lObjRemote.list();
File file = null;


for (int i = 0; i < files.length ; i++) {
String fileName = files[i].getName();
// ?? ??? ??? ??
String extension = fileName.substring(fileName.lastIndexOf(".") + 1);

//System.out.println("fileName = "+fileName);
System.out.println("in servlet fileName = "+fileName);
long size = files[i].getSize();
//System.out.println("size +"+size);
// ?? ??? 0?? ?? ?? ??? ???
//System.out.println("bfore size");


if ( (size > 0) && ((extension.equalsIgnoreCase("jpg"))||(extension.equalsIgnoreCase("xml")) )) {
file = lObjRemote.get(fileName, fileName);
System.out.println("inside servlet jpg file *** = "+file);
//ftp.put("c://jk","");

}
}


System.out.println("file = "+file);
System.out.println("files = "+files);

so how can take that file into Jsp...have to use FIstream...

Ah, you need some help with the servlet itself. I'll move this to the servlets forum for you.

Try something like the following code for sending the file to the client:

response.setContentLength(file.getSize()); //assuming file is an Object of class File
FileInputStream readFile = new FileInputStream(file);
BufferedOutputStream writeToClient = response.getOutputStream();
int byteRead;
while((byteRead = readFile.read()) != -1){

writeToClient.write(byteRead);
}
