i am generating pdf report using jasper(1.2.6).Its a simple logic where i am passing data as string in to jasper.I am just using the string variable in jasper and printing the content which sometimes contains huge data.

 

I our app server while generating swap file it is eating around 14 GB memory and application got hanged.Please suggest the cause and solution if someone is familia with the issue

maybe the problem is in the compiling of the jrxml, that's a common memory leakage problem. Instead of something like this 

JasperCompileManager.compileReportToFile(inputFile, destinationFile);

try

String inputFile = 
session.getServletContext().getRealPath("InputFile.jrxml");

String destinationFile = 
session.getServletContext().getRealPath("InputFile.jasper");

File jasperFile = new File(destinationFile);

if(environmentBeanFile.exists() == false)
{
JasperCompileManager.compileReportToFile(inputFile, destinationFile);
}
