I have written a standalone Java program to generate report. I am using Java 8, BIRT 4.3.0. I created rptdesign in BIRT designer and simply using it in Java program. When I run the report, it gets printed in designer using Run->View report; but it doesn't work in Java program and strangely it just skips the actual graph and shows X and Y axis's properly. Everything else gets generated except actual graph. This is for all report formats lke PDF, HTML etc.
Any idea what could be missing?
