.jrxml or .jasper?

[bobg1will]

Hello,

 

I'm running a web app that submits a request to a servlet which serves up a jasper report.  The servlet is running on tomcat.

Everything was going great until i started some load testing.  Tomcat is not releasing the memory used by the servlet to generate a report.

I have stripped the servlet down to the bare bones -

  - JasperDesign = load jrxml file

  - Replace certain values in the sql query obtained from the JasperDesign object

  - Compile the JasperDesign object

  - Use a JRHtmlExporter to export the report.

Is this the most efficient way to do this?  I realise the JasperDesign object is loaded into memory, is there a way to have the memory it uses recycled after the report has been printed?

I'm really struggling with this and would appreciate any help suggestions?  I can post my code if required.

Thanks,

Bobby
