Hello. I am new to JesperReports and after doing some basic reports I am now facing a more complex task. The data to run a query on is distributed over monthly tables (one for August, one for September and so on). It seems to me that a regular SQL-query won´t help here when a time period is freely selectable. So my idea was to write my own JavaBean datasource (based upon the SampleJRDataSourceFactory), pass parameters to it (e.g. the time period) and run a query on those tables affected. Accidentially I have not found a way to pass parameters to this Factory. My questions basically are: - is there a way to pass parameters over to the JavaBean - is there another way to solve this problem. Thanks for all your help :) Greets Stefan
