Using Loop to Print Multiple Barcodes

2005-07-14 07:53

I am producing a report with iReport 0.5.0 which allows users to specify how many barcodes they would like printed off. This number will vary from one to four. The barcodes need to be the same for each set of multiples. For example, two barcodes for Jim, then two barcodes for Bob, etc.. I know that I could accomplish this with a for loop or something similar but I can't figure out how to produce this result.

 

I have a parameter called $P{NUMBER_OF_LABELS} which stores the value of how many labels the user would like printed off. I've tried just about everything that I can think of to accomplish this, but have come up short.

 

Thanks in advance. I hope someone out there can help me.

Just design your barcode report with a SubReport that just prints the barcode field in its detailband... the other data are printed by your MasterReport.

 

In your SubReport-Element you say as DataSource-Expression the following:

 

new JREmptyDataSource($P{NUMBER_OF_LABELS})

 

in your SubReport-Expression you point to the SubReport-JasperFile or you pass your SubReport as "JasperReport-Object" from outside into the MasterReport also as Parameter)...

 

If your Barcode is a fieldvalue just pass that field as parameter from MasterReport to SubReport (as you tell him to use an empty JRDataSource with $P{NUMBER_OF_LABELS} empty records you can't use any other datasource

 

When I understood your problem right, I'm sure that would work! :-)

 

Hope you get what I mean?!?!?
