Upgrading from old version of Jasper

[camilos]

Hi Guys, I'm hoping someone here can guide me.

I've inherited a Jasper Reporting project that is quite old. The project uses jasperreports-2.0.5.jar & iReport3.0.0.

I'd like to recommend that we upgrade to the latest versions JasperReports 4.5.1 & iReport 4.5.1. But I need to give the effort involved in doing this.

Can you guys let me know how big of an upgrade this would be. Would the jar file just need to be replaced & the existing java code would continue working as is?  What about the jrxml files? Will they continue to work properly? Or would this whole thing require a complete re-write?

If anyone can give me a general idea I'd be extremely grateful.

Thanks

You will need to update the jars to the latest version.

If you have written your own server to run the reports it should still work with 4.5. We upgraded from 1.3.3 to 3.7.4 without changing any of our backend code used to execute the reports.

You do not need to re-write any of you jrxml files though it would be a good idea to recomile them with the lastest version.
