How can I debug the program ?

For web-start version, you should always observe the output from the Java Console Window. It usually provided the useful information. You can also use System.out.println() in your transaction source file to print out your own debug message. The output will also go to Java Console Window .

By default, the java console is not open.

1. Open the Java Web Start
2. File->Preference - > Advanced Panel -> check the "Show Java Console"

For executable jar version, you should start the tool from the command line rather than double click. The output goes to the command line window that you start the tool
