YAWL 4 Codelet

Printer-friendly version


There is no tutorial on how to import custom-made codelets into YAWL 4. It has changed a lot since version 2, and I honestly don't understand how to do that, since I'm a beginner at YAWL and any workflow problems for that matter.

Is there anyone who can tell/show me how to import codelets to YAWL 4? I need some tutorial like YAWL4 for dummies :)

Thanks a lot!


The change from version 2 is not that dramatic - there have been 4 methods added to AbstractCodelet that provide the option to override for finer grained control.

See the bottom of the AbstractCodelet class for detail on what those optional methods do. See ExampleCodelet for detail on how to write a codelet.

I have written a new tutorial:


Let me know if this works.

Hi, I tried both tutorials but I was unable to use my codelet. I get no error but it doesn't appear in menu when I try to use it.

still couldn't do it. tried a lot of things but no luck...
