Applet jar requirements for BIRT (4.2) ReportEngine [message #906016]

Hello.

I want to (need to) write an Applet that allows me to generate parametrised reports (in PDF format) using a Java Applet, but I cannot find anything online that tells me what dependencies (BIRT jar files) need to deployed along with it.

As you'll know I have to list the jars in the applet tag of the web page but I can't find a list of the jars needed. I know the required jar files vary depending on the abilities of my reports (which include charts), but even a minimal list of core required jar files is very elusive.

Can anyone help me here either in the form of a link or a list of jar files that I need to make available.

If you download the birt runtime, the required jars are in the
reportengine/lib directory. You can remove data source jars that you do
not need as a start.

Thanks for the time Jason. I've downloaded the runtime and copied the runtime_4.2 jar file to the same place as my web page containing the applet.

I've added the jar file to the archive attribute, but I now get an error at start up saying it can't find :

org/eclipse/core/runtime/CoreException

System.out.println("Starting...");
eConfig = new EngineConfig() ;
eConfig.setLogConfig(HOME + "/", Level.SEVERE) ;
eConfig.setLogFile("BirtLog.log") ;
eConfig.setTempDir(HOME);
try {
	System.out.println("Creating Platform Config");
	pConfig = new PlatformConfig() ;
	eConfig.setPlatformContext(new PlatformFileContext(pConfig)) ;
	Platform.startup(eConfig) ;
	System.out.println("Creating Report Factory");
	eFactory = (IReportEngineFactory) Platform.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY) ;
System.out.println("Creating Report Engine");
rEngine = eFactory.createReportEngine(eConfig) ;
}
catch (BirtException e)
{
	e.printStackTrace() ;
}

I would really appreciate some help here I'm making no progress whatsoever.

Start off by trying to add all the jars from the
\birt-runtime-4_2_0\ReportEngine\lib directory. You can prune them once
you get it working.
