Hi to all!
I'm trying to run BIRT (in a Webapp) so to learn how to use it I'm running a test class in Eclipse with a main method to produce the report.
My strategy for the test (I'm new to BIRT) is to use to follow the ScriptedDataSource design example so I have a couple of classes to supply the Data Sources for the reportDesign ( which has 2 tables.. like 2 subreports I hope). If I run and view the report PDF using the IDE (Ecipse).. it work !
How can I run and view the report using my main method programmatically (as if by the WebApp)?
Am I using the right approach? Do you/how can you use a scriptedDatasource ? Maybe you don't use a ScripteddataSource to use BIRT in a WebApp ?
Please give any feedback you can, it will help ?
Thank you in advance !
it crashes at task.run();
I will attach my classes and report design ...
Below is the Error and reportGenerator.java
SEVERE: The output format pdf is not supported.
org.eclipse.birt.report.engine.api.UnsupportedFormatException: The output format pdf is not supported.
