Hi,
here is my piece of source code for that problem:
stream = file.getInputStream();
zipFile = new File( user.path, user.kurzname + "-upload.zip" );
bos = new BufferedOutputStream( new FileOutputStream( zipFile ) );
int bytesRead = 0;
int count = 0;
byte[] buffer = new byte[ 8192 ];
while ( ( bytesRead = stream.read( buffer, 0, 8192 ) ) != -1 )
{
bos.write(buffer, 0, bytesRead);
count += bytesRead;
if ( count > 2000000 ) // THIS IS THE MAXIMUM SIZE
{
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError( "error.upload.file" ) );
return mapping.findForward( "failure" );
}
}
And I have a finally block surrounding this where I close all streams :-)
