I've extracted the BDJ.JAR and the 77770.jar into the same directory. But trying to run the code fails:
Code:

Exception in thread "main" java.lang.NoSuchMethodError: main
And indeed none of the jar files contains a class with a "main" function. How is the code executed? I noticed that the *.bdjo files in the BDJO directory are referencing the class files in the jar. That's the 07777.bdjo:
Code:
