Hi

I am also facing the problem to upload files in weblogic.
I got following exception like
java.net.ProtocolException: EOF after reading only: '16384' of: '269635' promised bytes, out of which at least: '0' were already buffered.

I am uploading one file in server but my code is working fine if the file size is less than 4096 bytes, if i hv given more than that i got exception.
if u refer my code, u can get some idea, simmilarly if u get the solution for that it will be helpful for me..

my code is...
private void uploadFunction(HttpServletRequest req,HttpServletResponse res){


String contentType = req.getContentType();
System.out.println("Content type is :: " +contentType);
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
try{
DataInputStream in = new DataInputStream(req.getInputStream());
int formDataLength = req.getContentLength();

if(formDataLength<=5000000){

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("\""));



int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1,contentType.length());
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;
if(saveFile.length()!=0){
saveFile="D:\\soft\\"+saveFile;
FileOutputStream fileOut = new FileOutputStream(saveFile);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();
}


}
}catch(IOException e){
System.out.println("except.........."+e);
e.printStackTrace();
}
}
thx in advance
