copying file into database

[Monty Guppy]

This is the gist of what I am trying to do:
- I need to read a PDF file located on my machine through my java program.
- The PDF file needs to be then converted into a byte array
- The byte array then needs to be inserted into a (MS-SQL) table field (type=image)
- The PDF file then needs to be deleted from my machine
I am getting very confused with the different types of inputStreams, and how to use them.
Any help would be greatly appreciated.

// handle to file
java.io.File file = new java.io.File("filename.pdf");
// read contents of file into byte array
byte[] buff = new byte[2048];
// use FileInputStream to read bytes from file.
java.io.FileInputStream in = new java.io.FileInputStream(file);
// use ByteOutputStream to construct byte array.
java.io.ByteOutputStream out = new java.io.ByteOutputStream(2048);
int c = in.read(buff, 0, buff.length);
while(c == buff.length){
    out.write(buff, 0, c);
    c = in.read(buff, 0, buff.length);
}
if(c != -1){
    out.write(buff, 0, c);
}
contents = out.toByteArray();
in.close();
out.close();
// write contents to database as you see fit.
// delete the file
file.delete();
