Export jsp to PDF

I want to export the web page developed using JSP to PDF. Please let me know if there is any software (of free cost) found for doing that.
I tried already with IReport and HighWire(CORDA product costs about $2999). I want to know the product of low cost. Please suggest me the product and if anyone have idea for getting the embedded HTML dynamically from the JSP Page, please let me know the idea.

Thanks
Ramya
