sub report in jasper

[johnkennedy antony]

hi friends,

i am new to jasper, i face some problem while generating the sub-report. when i generate the sub report static content and parameter value has displayed but i can't display the list value. Actually i used data source in sub-report if i run the sub report separately that list value is come but if i make it as sub-report that list value is not come. can any one explain how to display the list value in sub-report.
