Hi, I have the following problem: I need a JRBeanCollectionDataSource starting from a parameter for the query that have to be performed to populate itself. I would like to pass some parameters to MyBeanDataSourceProvider that extends JRAbstractBeanDataSourceProvider. I have the "JasperReport" parameter, and from it I can find out the name of my parameters, but I can't find out the values of that parameters, in order to perform the query that will populate the JRBeanCollectionDataSource(collection). Anyone of you can help me?? Michele
