Displaying Rows from a collection ?? HELP

[javapedant]

Hi

I have a collection that is to be passed to the report for displaying.

When I pass the collection through JRMapCollectionDataSource,  the entire report is being generated for each row of the collection.

But I want to display all the rows in the same area .

I'm sorry if my english is poor. But please go through the attached files and i'm sure u'll understand what i mean.

 

Attached are my files

 

 java file - GenerateReports.java

JRXML - FlightReport.jrxml

PDF report i'm able to generate currently : FlightReport.pdf

My required output : show.bmp ( which i'm desperately in need of )

 

Please help me with a possible solution.

 

Thanks in Advance

It's not the "right" way to use jasperreports... each element of a colelction corresponds to a row in the report... hovewer you can can pass a string field like this (your filed has expression $F{something} )

Thanks for the reply.

SO do you mean  need to convert all my fields in a row to string and pass ??

Only if you don't understand subreport (and Collection) concepts...

Thank you for your reply.

I started making a subreport for displaying my collection.

But i'm not sure wether to pass my collection through the main rreport datasource.

DO I actually need to create a new datasource for subreport??

your bean must be something like this:

in the report you have 3 filed:

flightNumber

flightName

flightDescription

then pass at your report a Colection<FlightBean > ...

Code:

import java.io.Serializable;public class FlightBean implements Serializable {    public String getFlightNumber() {        return ...    }    public String getFlightName() {        return ...    }    public String getFlightDescription() {        return ...    }}

Ohh..Thanks for the reply agn.

Ok. I'm doing the same thing.

But do I need to pass this as a datasource to my main reoprt or the subreport.

 

And if it is to the main report..How about the other collections..do i need to have everything into the same bean ?

sorry, yesterday I did not understand ... No subreport is required, this report is very easy: see the code...

I've used the same method name as you in your code... that's ok? ;)

I found a similar example as you have told above. When I try to implement the o/p is still the same. A new page is being created for each row in the data source. And so 4 pages are being created. I understand it should be in 1 page..But unable to figure why multiple pages are being created. Any idea ??

Reduce the heigth of the "detail" band!! And use column header band for title! see the attachment!
