B4J Question SLC error

[elitevenkat]

I tried to wrap a jar file and got he following error. The library is listed in the b4j lib manager. however after selecting it does not allow me to create an instance (dim pb as PrintBill) in the code.

What could be the problem ?

You need to add @ShortName("PrintBill") to the class.
