Bean not showing up in add bean dialog

I have been unable to get the bean I wrote to show up in the add bean dialog.

What possible errors could I have made along the way?

My class is a simple class that follows bean design patterns, No args constructor etc.
It is compiled into a jar file and placed into the servoy/bean directory.
I restarted servoy developer. It won’t show in the dialog.

Is it marked as being a bean in the jar manifest file? (see other beans as example)

Okay that was it. Thx.
