Hi,
My requirement is to generate birt report by passing XML files. I tried the below code, but the final reportis blank..Please help me on this..
import java.util.logging.Level;
import java.util.HashMap;
import java.io.*;
import java.net.URL;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
