droolsoptaplannerrunnable-jar

Why appear this error when run optaplanner .jar?

I have an optaplanner aplication, and i want to export it as a runnable jar, but when i run the jar, appear a error and I don't know why.

I'm using the Vehicle Routing example, and i want to use the GUI interface without eclipse.

Solution

  • Because Drools is incompatible with uber jars. Use one of the other score calculators if you really want to run with an uber jar...
