[Springframework-developer] Help!!!

[Kopylenko, D. <dko...@ac...>]

Hello everybody. I have a big problem and if anybody could help I would
definitely appreciate it.

In the nutshel, I have a MultiActionController with one of the request
handling methods which does retrieve three lists of "reference data" from
ApplicationContext (I load the reference data at the bootstrap, similarly to
CachingCalendar in the BoxOffice application) and puts the "lists" in the
model Map to make it available to a View:

public ModelAndView processProgramInquiryAdd(HttpServletRequest request,
HttpServletResponse response)
	throws ServletException {

		Map model = new HashMap();
		model.put("programLookup", ((GradApplicationReferenceData)
getApplicationContext().getBean		
	
("gradApplicationReferenceData")).getPrograms());
		model.put("stateLookup", ((GradApplicationReferenceData)
getApplicationContext().getBean
	
("gradApplicationReferenceData")).getStates());
		model.put("countryLookup", ((GradApplicationReferenceData)
getApplicationContext().getBean
	
("gradApplicationReferenceData")).getCountries());

		// Rest of the processing
		.........................
		return new ModelAndView(ESTABLISH_NEW_PROGRAM_INQUIRY_VIEW,
model);
}

My dev. environment is NT4 with around 300M of RAM, Sun's JDK 1.4 and JBoss
3.0.4
When I run this request handling method several times (e.g. hit the submit
button on the web page), after about the third time the JVM dies with:

Exception in thread "CompileThread0" java.lang.OutOfMemoryError: requested
32756 bytes

When I comment out the block of code which puts the "reference lists" into a
model Map, it runs fine.
Could anybody, please tell me if the code is ok and it does not create a
problem. And what could it be?

Thanks,

Dmitriy.
