Dynamic data as parameters

2003-07-23 09:47

Hello,

 

I am trying to pass rows generated by a Java program as parameters to the report. For instance, one of my reports generates has three columns, client order, date and amount ( similar to one of the sample reports ) and at runtime I populate these columns with numerous rows depending upon certain constraits. The Java program currently generates these rows, so I was wondering if I can directly passes these rows to the report.

 

I understand that in one of the examples the parameters are stored in a Map. The reason why I am not embedding a sql directly within the report is, I am migrating from an old framework to Jasper and it would be easier if I just pass the data than to re-write all sqls again.

 

Thank you all in advance.

If you don't want to use JRResultSetDataSource (which is the default when you embed sql in the template), just define your own. In my reporting work, I always use a custom datasource that reads from an ArrayList containing the rows stored as Object[].
