    I implemented my own data source which is JasperReports DataSource Provider. It works in iReport, but doesn't for Jaspersoft Studio.

     

    When I press the test button for DataAdapter Wizard I get the following exception:

     

    java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/data/JRAbstractBeanDataSourceProvider

    A attach the screenshot for DataAdapter Wizard. The added jar in the file path, on the screenshot, is of course my library which has the data source.

     

    Based on above exception it seems that the JasperReports jar is missing in classpath. I think I shouldn't add it in the dialog because it should be already provided. However, if I add it, the above exception disappear, but the new rise:

    java.lang.ClassCastException: de.psi.ee.xch.jr.dataSource.timeseries.TimeSeriesDataSourceProvider cannot be cast to net.sf.jasperreports.engine.JRDataSourceProvider

    I've experienced it on version 6.1.1.The problem is when you try to pick in customDS class extending net.sf.jasperreports.engine.data.JRAbstractBeanDataSourceProvider.I've traced it to missing part of the class path in:jaspersoftstudio-6.6.1-win64\plugins\com.jaspersoft.studio_6.1.1.final.jar\META-INF\MANIFEST.MF added additional package on: (net.sf.jasperreports.engine.data)com.jaspersoft.studio.wizards; uses:="net.sf.jasperreports.engine.dataand then I can create the DataAdapter with DataSource.Although I've managed by this fix CREATE the DS (the TEST does not fail with the NoClassDefFound) I can't really use it later on. I can't pick classes on DataSet Query Dialog => Java Bean. So there is more into it in other places probably.
