Everything works smooth, when I'm not using threads in application, while calling jasper API to generate reports. But as I saw, if I will use java thread pools, I could generate reports much faster. Only one problem. When I use thread pools, some reports are generated wrong - without parameters filled.
...ExecutorService executor = Executors.newFixedThreadPool(5);for(int i = 0; i < 1000; i++){ Runnable runnable = new Generator(parameters, "target/resources/Invoice.jasper", "Invoice", i); executor.execute(runnable);}...public class Generator implements Runnable {...@Overridepublic void run() { try { JasperPrint jp = JasperFillManager.fillReport(sourceFileName, params, new JREmptyDataSource()); JasperExportManager.exportReportToPdfFile(jp, "./target/resources/" + printFileName + "-" + counter + ".pdf");...[/code]
I know, that it can be related with subreprot filling, because these jasper API generating methods already working in multi-threading. Maybe anyone can comment on that? Is it possible to ganerate a lot of reports while using executor pool?
Some generated reports are not filled with parameters
