Thanks for suggestion. I have tried with virtualizer. But, still I am facing this problem.

4GB memory is being used for application. We can not increase more than that.

Please, consider the following code snippet - JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(jasperReportBeanList);String printFileName = JasperFillManager.fillReportToFile(templateFilePath, parameters, beanColDataSource);[/code]Here , jasperReportBeanList containing over 250000 records. Now, at the time of executing JasperFillManager.fillReportToFile(templateFilePath, parameters, beanColDataSource) method I am getting GC over exceeded error or out of memory error. Please, note that I have also added the following line in my code - DefaultJasperReportsContext context = DefaultJasperReportsContext.getInstance();JRPropertiesUtil.getInstance(context).setProperty("net.sf.jasperreports.xpath.executer.factory", "net.sf.jasperreports.engine.util.xml.JaxenXPathExecuterFactory");[/code]But, still I am getting error. Any help is appreciated.
