Java Servlet Hangs After Creating Barcode
If the Java Program or Servlet hangs after the creating barcode, use the System.exit(0); command to exit the method creating the barcode. If this does not resolve the issue, similar problems have been associated with a corrupt JVM so try another machine with a different version of the JVM. Usually the System.exit(0); command is placed after the encoder command.
barCodeEncoder bce = new barCodeEncoder(bc, "JPEG", "newfile.jpg"); System.exit(0);
