iReport connectivity with desing user interface in java

[hardikjadhav]

hello friends,

i have designed one user interface, which takes criteria for report.
i have desinged that report in iReport.

but what i want to do is, whatever the criteria i will pass through
interface the query should be generated and report should be generated.

What can i do for passing this criteria (attributes) to iReprot at runtime.
How can i connect to iReport at runtime.

please reply..thanks...
