Hello, all. I have installed the IReports plugin for NetBeans 6.1, and am trying to create a new Report using a JRDataSourceProvider, with no luck. I've copied over the PersonBeansDataSource http://jsourcery.com/api/sourceforge/ireport/1.2.8/it/businesslogic/ireport/examples/PersonBeansDataSource.source.html#jj1537777112 and all the associated Beans (PersonBean, etc.) to my local NetBeans project. The class compiles correctly, so it must know where the JasperReports libraries are. When I go New > Other > Report > Report Next Next (use the default file name) select New (datasource) select JRDataSourceProvider and click Next name = "foo" JasperReports DataSourceProvider class = PersonBeansDataSource Click Test ClassNotFoundError! Msg PersonBeansDataSource Possible not found class PersonBeansDataSource check your classpath! ...okay. I'll try full.path.to.the.class.in.my.project.PersonBeansDataSourceProvider. I get a ClassNotFoundError! Msg: full.path.to....etc...PersonBeansDataSource. If I cancel, and use the default JRDataSourceProvider class, com.jaspersoft.ireport.examples.PersonBeansDataSource and click Test, I get Connection test successful!. Is there any way to get the IReport plugin to see a class in my file as a JRDataSourceProvider? Thanks for any help. -Ed
