Hi Everyone,
I am trying to adapt some of the logic from this signature capture java applet [http://www.planet-source-code.com/URLSEO/vb/scripts/ShowCode!asp/txtCodeId!110/lngWid!9/anyname.htm] into a bean that is usable with servoy. However, when I create the jar file and place it in the beans directory, and restart the repository, it doesn’t show up on my list of beans. I take it there is something wrong with my code but I have no idea what it is – if someone who has experience writing beans could take a look at it I would appreciate it.
