subreport list of data

[frblusso]

Hello

 

i have the problem below :

 

i have a list of Planes. A plane contains text fields (id, name) and a list of flights(object B)

Each flight has text fields f1, f2 ...; .

I want to create a report to list all the Planes id ,names and flights details

 

For example :

plane1 A320

volAF

volKLM

volXXX

plane2 A330

volAF

volXXX

 

 

i have created in my java programm a JRBeanCollectionDataSource(PlanesList) that have all the information it contains a list of (id, name ,flightList) but how could i

put flightList detail information in the report?

 

I think I have to use a subreport , the main report is used to generate the list of planes whith text fields id and name.

In the subreport I list the text attibutes of one flight.

The problem is that I do not know how to specify that the subreport needs to read (as its own datasource) the list flightList found in the main report.

 

i search in the forum for any information but i only found a solution if the first list has only one object.

 

i really need help, thancks!

 

Regards

I found this solution to my problem :

i have a bean Avion (id, name, java.util.List flightlist)

in the main report, I insert a subreport, with this property,

use datasource expression

new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{flightlist})

 

In Subreport(other) i put the path to the subreport.

and in my java application, i have just to create the JRDatasource to give me the data Avion.

 

regards
