how to use two javabean datasources together

2006-04-11 01:13

 

I have a report with a crosstab and a chart, and they have different javabean datasources. Is there a way to pass two different javabean collection datasources to the JasperFillManager Object ??

 

For example :

 

jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

myCollection

);

 

I have one collection in the myCollection variable. How can I pass the other javabean collection to the constructor ? Or I must use in this particular case a connection ?

 

thanks in advance,

 

leti

I asked for this function about a year ago.

 

the only way is to have a single datasource, and have some switch logic to switch between the other 2.

There is no way to pass two data sources to a report, but if you only need a data source for a chart and the other for a crosstab (i.e. you don't have a detail band for the data), you can create two subdatasets for the chart and crosstab, pass your two bean collections as report parameters and use the parameters to instantiate the subdatasets.
