I am sending a List as a parameter to a jasperreport as a collection type on the report end. How do I parse the collection to display teh items in the necessary report fields?

Still need some help with this. I have not been able to take a collection type parameter and parse out the specific elements to use in my report fields.

Thanks for your reply Martijn.

I am Still Waiting for the solution.

Now I have got one more issue.
i.e i am passing an Integer[] as parameter to the .jrxml file .
in my .jrxml i have
<parameter name="id" class="java.lang.Integer"/>

Now its throwing me exception
"JRException: Incompatible [Ljava.lang.Integer; value assigned to parameter"

i m not sure how to resolve this..

Well you're trying to pass an _array_ of Integers into an Integer, so that's not going to work, you need to look up how to pass in Arrays (or Lists).

I have tried passing an List.. But as the field in my data base is of int type, its not working... well that was obvious.. Is there any other alternative???
