Teodor Danciu Posted October 23, 2006 Share Posted October 23, 2006 Hi, When upgrading, pay attention to the "Requirements" page in our documentation. They might have changed in the meantime.http://jasperforge.org/sf/wiki/do/viewPage/projects.jasperreports/wiki/Requirements I hope this helps.Teodor Link to comment Share on other sites More sharing options...
