1 to n reports in a single report.

[bobz28]

Hi All,

I am trying to create a template for a report that can be from 1 to many (around 10 reports) in one report output. Depending on the user input (~10 drop down lists and each list if selected will eventually populate a report). Ex. if user select inputs from 5 drop down lists then I will have to generate 5 reports, one after another, if they select 10 then create 10... What is a best way to accomplishing this?

Thanks-

Bob

Please find the below code. One report corresponds to the one jasper file. Appending one report with another can happen with the code given below. It will be an as-is append.

Code:

     for( int i = 0; i < listOfInputjasperpath.size(); i++ ) { try {        JasperPrint jasperPrint = JasperFillManager.fillReport(          listOfInputjasperpath.get( i ) + ".jasper", params );        listOfJasperPrint.add( jasperPrint );      } catch( JRException e ) {        throw new RuntimeException( "Exception related to Jasper Filling Data " + e );      }

Hi shrije,

 

Thanks for your reply, I am using Jasper with Spring framework and the Jasper template is the same for all reports... Can code similar to this happen inside the template or a scriptless?

It will stll with the same template since jasperPrint is the one which will be different for different reports in your case. Just that you have to provide different datasources to the same jasper file to get the jasper print object to finally append them.

Hi,

 

Such code needs to stay in your Spring application. I cannot be part of a report template or scriptlet.

It is your own application code.

 

I hope this helps.

Hi,

Can somebody help... How can I append one report after another in Spring Hibernate framework?

Here is what is look like in the controller:
Map<?,?> model = new HashMap<?,?>();
List<?> report = getReport();
String[] fields = new String[] {"a", "b", "c"};
HibernateDataSource ds = new HibernateDataSource(report, fileds);

model.put("title", title);
model.put("dataSource", ds);
...
return model;

Thanks a lot.

Hi All,

Well, I think I can create a subreport to handle this issue, but is there a way to call and pass it diff datasources?

 

Thanks-
