JRSwapFileVirtualizer Problem

[satragyaha]

Hi

 

In my client/server web application, i want to generate pdf reports for clients.

I have a 20 thousand recorded dataset (approximately 10 thousand pdf pages)

I tried JRFileVirtualizer but it didn't work for this huge set. Indeed, it worked fine for

nearly 2500 recorded sets. And then i used JRSwapFileVirtualizer but it did not work too.

 

My report consists of 2 subreports and a two times repeating image per a page. After my attempts

i got some error messages like these:

 

FATAL ERROR in native method: JDWP NewGlobalRef, jvmtiError=JVMTI_ERROR_NULL_POINTER(100)

JDWP exit error JVMTI_ERROR_NULL_POINTER(100): NewGlobalRef

 

or

 

No input source supplied to the exporter.

 

Here is some of my code snippet:

 

Code:

JRSwapFile mySwap = new JRSwapFile(TEMP_FILE_PATH,100,100);		
JRSwapFileVirtualizer swapVirtualizer = new JRSwapFileVirtualizer(JRFILEVIRTUALIZER_OBJECT_COUNT_INVOICE,mySwap);	
swapVirtualizer.setReadOnly(true);					

Map parameters = new HashMap();
parameters.put("INVOICE_SUBREPORT_1", subreport1);
parameters.put("INVOICE_SUBREPORT_2", subreport2);
parameters.put(JRParameter.REPORT_VIRTUALIZER, swapVirtualizer);
	

jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, obj);		

 

Any help would be appreciated.

Thanks in advance.
