Java - Simple Design Engine API

This example demonstrate using the DE API to create a simple report. Add comments at the bottom of the example. Moved from the old Design Engine API area.

Thanks for the example. But mine is getting below error.While run as java standard alone program prompting below error. Please advise, much appriciate

I used same example and downloaded birt_runtime C:\birt-runtime-4_4_2\ReportEngine

Error : Error : A JNI error has occurred , please check your installation and try again.
