I've implemented JRDataSourceProvider and JRDataSource interface to author JRXML. I've package them inside jar and added it to jasper project classpath and jasper studio plugin directory(inside studio installation directory). Afterdoing this configuration, i'm able to locate my Provider classes and fields while adapter definition. I used those fields and able to see the preview data, however after sometime i started getting ClassNotFound exceptions for the same classes which were visible to me earlier.
Went through studio ultimate guide, apart from adding custom jar to buildpath, i don't find any other recommendation for this. Can you please recommend if you know the solution for this?
