Topaz Signature Applet not connecting to Serial ClipGem on COM1


Here is my problem:

I cannot connect to serial port COM1 using ClipGem (Model: T-C912-B1) in a Java Applet.

I have verified that the Java class I built works as desktop application extending Frame and I can successfully capture signatures on COM1 and also on a ClipGem USB (Model: T-C912-HSB-R)

public class SigPlusSimpleDemo extends Frame

Next, I changed Frame to JApplet and try again using my new applet with the USB ClipGem to verify the applet is still successfully capturing signatures and USB still works as expected and it does.

However, when I try the same applet on serial port signature pad, I cannot connect to it. Remember, I already verified that it's working as a desktop application.

Does anyone know some reasons that can be causing this problem on COM1?

Has anyone experienced this problem?

Am I missing something?

Note: I am familiar with Java and have some programming experience, but I am no expert. Also, I have been going back and forth with Topaz Systems looking for a solution and I am currently waiting for another reply from them.


Solution

  • If the code works fine as a desktop application, a way to work around this issue would be to deploy your application as a Java Web Start application instead of an applet.
