Hi

> Hi, I am use the File Upload. I need to read the whole file contents in a
String buffer.

Why into a String buffer?
This is propably a charset encoding problem.
Do NOT read it into a stringbuffer.

See FileWriter documentation:
> FileWriter is meant for writing streams of characters. For writing streams
of raw bytes, consider using a FileOutputStream.

So change your method:

    .....
    int nSize=0;
    // now !item.isFormField()
    java.io.InputStream fstrm = item.getInputStream();
    int rnum=0;
    buf = new byte[262144];       // the doc file size I am testing is
13XXXX buyes.
    while (rnum>=0){              // I have to read all the contents
      rnum = fstrm.read(buf, (int)nSize, 100);
      if (rnum> 0) nSize += rnum;
    }
    fstrm.close();

    if ( nSize>0) {
      // I like to test if it read correctly:
      FileOutputStream fileOut = new
FileOutputStream("C:/DocAttachment/strFileName.doc");
      fileOut.write(buf, 0, nSize);
      fileOut.flush();
      fileOut.close();
       ......
     }


Beside that:
You know that you could simply do:
   item.write( new File( "C:/DocAttachment/strFileName.doc" ) );

  Steffen
