RunAndRender - Null Pointer Exception

Hello,

Two days ago it was my first attempt of deploying grails aplication (Birt plugin included) on Tomcat server. While deploying my application on STS embedded TC Server (local host) there werent any problems doing it. The story turns out different when I produce a war file (-grails war) and deploy it on remote Tomcat server.

Application works well till it reaches the point where it has to generate html report with calling runAndRender method.

birtReportService.runAndRender(reportName, reportParams, htmlOptions)

So I started debugging it and found out that the error happens in this line (Null Pointer Exception) :

task.run()

And here is the comparison of IRunAndRenderTask task structure from running application in local or remote mode:

Local:

"task"	 (pending)	
	cancelFlag	false	
	dataSource	null	
	dataSourceReportlet	null	
	defaultValues	HashMap<K,V>  (id=610)	
	emitterID	"org.eclipse.birt.report.engine.emitter.html" (id=611)	
	engine	ReportEngine  (id=377)	
	executionContext	ExecutionContext  (id=612)	
	format	"html" (id=614)	
	inputValues	HashMap<K,V>  (id=615)	
	layoutEngine	HTMLReportLayoutEngine  (id=616)	
	log	Logger  (id=619)	
	pageHandler	null	
	pagination	"page-break-pagination" (id=624)	
	parameterChanged	false	
	platformContext	null	
	progressMonitor	null	
	renderOptions	HTMLRenderOption  (id=415)	
	resourceLocator	ResourceLocatorWrapper  (id=630)	
	runningStatus	2	
	runValues	HashMap<K,V>  (id=633)	
	statusHandler	null	
	taskID	32	
	taskType	3	
	timeZone	JavaTimeZone  (id=637)	
	ulocale	ULocale  (id=641)	
	userAcls	null

Remote:

"task"	 (pending)	
	cancelFlag	false	
	dataSource	null	
	dataSourceReportlet	null	
	defaultValues	HashMap<K,V>  (id=409)	
	emitterID	null
	engine	ReportEngine  (id=410)	
	executionContext	ExecutionContext  (id=413)	
	format	null	
	inputValues	HashMap<K,V>  (id=415)	
	layoutEngine	null	
	log	Logger  (id=416)	
	pageHandler	null	
	pagination	null	
	parameterChanged	false	
	platformContext	null	
	progressMonitor	null	
	renderOptions	HTMLRenderOption  (id=379)	
	resourceLocator	ResourceLocatorWrapper  (id=419)	
	runningStatus	0	
	runValues	HashMap<K,V>  (id=421)	
	statusHandler	null	
	taskID	18	
	taskType	3	
	timeZone	JavaTimeZone  (id=422)	
	ulocale	ULocale  (id=424)	
	userAcls	null

As you can see the difference is in EmitterID and format option.
I am stuck right now because I have no idea what is going wrong and how to debug deeper, so I would really appreciate any help you guys can give me.
