Hi, at the beginning i used DataStore ds= DataStoreFinder.getDataStore(propertiesMap); After that i got my FeatureSource with SimpleFeatureSource source = ds.getFeatureSource("Table_A"); After Ron's reply (thanks Ron!) i changed the DataSource to JDBCDataStore ds = (JDBCDataStore) DataStoreFinder.getDataStore(propertiesMap); ds.setExposePrimaryKeyColumns(true); Now the primary keys get found and i can use them in the Join-Statement, but i get an SQLException (Invalid column index). I think i'v got another mistake now.
