All demos provided with Aspose.Slides for JasperReports are changed standard demos. It’s better to copy all demos to the JasperReports demo folder:
...\jasperreports-2.0.5\demo\samples\
And use standard commands sequence to build and export reports:
ant javac
ant compile
ant fill
ant ppt
Please do not forget to run HSQLDB with test database to fill reports with data.
Most of demos (except Charts) already have generated presentations so you can skip all “ant” steps and check results immediately.
