Birt configuration

james681

Hi,


I am a newbie in java and birt so i wanted to integrate Birt in java in order to build a simple report and here is the exception that i got:



org.eclipse.birt.core.exception.BirtException: Cant startup the OSGI framework
at org.eclipse.birt.core.framework.Platform.startup(Platform.java:91)
at test.DeDemo.buildReport(DeDemo.java:75)
at test.DeDemo.main(DeDemo.java:37)
Caused by: org.eclipse.birt.core.exception.CoreException
at org.eclipse.birt.core.framework.osgi.OSGILauncher.startup(OSGILauncher.java:90)
at org.eclipse.birt.core.framework.Platform.startup(Platform.java:79)
... 2 more

Exception in thread "main" java.lang.NullPointerException
at test.DeDemo.buildReport(DeDemo.java:90)
at test.DeDemo.main(DeDemo.java:37)

I have the eclipse IDE for java devlopers and i have installed birt by update manager.

Any help will be appreciated!
thanks

Happy

Probably missing classpath entries, or have too many.<br />
<br />
You should only import the contents of the ReportEngine/Lib directory into your classpath (plus whatever non-birt related entries you need). If you import the ReportEngine/Plugins directory, you will get many many errors.<br />
<br />
As an example, here is what I did:<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
String BIRT_HOME = "D:Appsbirt-runtime-2_5_0ReportEngine";
EngineConfig ec = new EngineConfig();
ec.setBIRTHome(BIRT_HOME); // Probably do not need this step
ec.setEngineHome(BIRT_HOME);
try {
System.out.println("Starting up Platform");
Platform.startup(ec);
IReportEngineFactory factory = (IReportEngineFactory) Platform.
createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
IReportEngine engine = factory.createReportEngine(ec);

// Do run and render code
engine.destroy();
} catch (BirtException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally
{

Platform.shutdown();
}
</pre>
