xport V6.6 to newers, java applet gives nullpointer exception

[onair]

Hi,
I was using xport 04 with a Java applet for remote control of a tranciever. I bought the java applet from a programmer as a .cob file. It was working properly, but after xport version 6.7 it is not working. java gives nullpointerexception error, java console:

How could i solve the problem? I am not good enough at Java, is it possible to solve with little changings?

There is no gtp1 reference in the sample java web files (web.zip) distributed by Lantronix.
Without the source code, or at least the archive name, I will not be able to trace this further.
This: Connecting to 192.168.2.28:30718 failed!
might be an indication of the increased enforcement of the 77FEh protocol we started in V6.7. I would suggest the original coding did not follow the specification.

I can share the .cob file with you.
How much work or changing is required to make applet proper for new 77FEh protocol?

The COB file is not helpful. The underlying JAVA files are compiled into CLASS files that are likely in the COB archive. You can send me the COB and I will inspect it. Send it to:
