How to pass in all data

2003-12-10 09:02

If I already have a Collection of data that I want to use in a report, how do I pass that in instead of specifying a query in my report.

 

I looked for examples and searched the archvies, but couldn't find anything about this. Can some one point me to some info on this?

Hi,

 

All you have to do is to wrap your collection inside

a JRBeanCollectionDataSource.

Take a look at the "datasource" sample provided

with the project source files.

 

I hope this helps.

Actually..there is another way to do it...what i did is that i have my data in a databean say "ReportBean"...i put the object as a parameter and pass it to the runreport api...

 

HashMap parameters = new HashMap();

parameters.put("report", retData);

 

here "retData" is an instance of my data bean..having all my data..then...

 

JasperRunManager.runReportToPdf(<name of template>, parameters, <some dummy data source>);

 

in the report i get this parameter (named "report" while putting) and i can use the usual getter methods to get the data...

 

hope that helps
