problem in jasper report and subreport

[singh Mari]

i am using jasper report and subreport for print purposes. when subreport are using the following error messages came.

" The supplied java.sql.connectionobject is null"

Are you trying to pass the connection Object to the subreport?

Ideally if you are using subreports in Jasper, you should get all your data in a collection and then pass all the data to main report which again can pass the data to sub report.

This is the way I have done the Jasper report.

I am sorry to say, but how is this problem related to JSF?

[Anurag Blore]

This problem is not related to J?SF it related to Japer Rports
