Jasper reports problem with huge data

[shivamadagani]

Hi,

We are trying to export data to excel using jasper reports. The size of data varies from 1 MB to 1 GB.

When huge data is to be filled into the jasper report, it is taking much time for the report generation. It took 5-10 mins to generate one of my report.

Please help me with a solution where I can optimize this filling process of the jasper report, so that reports can be generated quickly?

We are using jasperreports-3.0.0.jar and jdk1.5 in my application.

Please provide with any source code if available.

Thanks
Shiva
