Servlet Tutorials

Q.How to upload an image from servlet/jsp into server from clients machine?

In the JSP

<form name="regform2" method="post" enctype="multipart/form-data">

<input type="file" name="ImageFile" id="ImageFile" onChange="uploadImage()"/>


uploadImage() - java script - document.regform.action ="<%=request.getContextPath()%>/dfdmin?cmd=uploadimage";


In the servlet - add the below code.

String rtempfile = File.createTempFile("temp","1").getParent();

MultipartRequest multi = new MultipartRequest(request, rtempfile, 500000 * 1024);

File rnewfile=null;

rnewfile = new File(CommonArt.IMAGE_PATH+"jsp"+File.separator+"images"+File.separator+"uploadImage"+File.separator);





//Enumeration files = multi.getFileNames();

//while (files.hasMoreElements()) {

File f = multi.getFile("ImageFile");


FileInputStream fin =new FileInputStream(f);

RandomAccessFile r = new RandomAccessFile(rnewfile+File.separator+f.getName(),"rw");

filename = f.getName();

// FileOutputStream fos =new FileOutputStream(rnewfile);

byte sizefile[] = new byte[5000000];


// fos.write(sizefile);





This will upload multipart file to your path.

Note : get cos.jar from oreilly website.
