multivalue parameter

2003-03-13 13:22

Hello people!

 

I was trying to use Jasper with Ireport and i´ve got some questions.

When i use a database connection with a SQL select it works realy fine. I

used a field on the IReport toll ($F{field_name}). In another java

class i needed to use a list of parameters, but i cant make it work. Does

anyone knows how can i put on the report an Array( collection, list,

...) on a parameter?

 

Thanks for your help

Hi,

 

This smells like subreports combined with

JRBeanCollectionDataSource.

You can pass your collection as a parameter,

but you need a subreport to iterate on it and

generate some output in the master document.

 

Check the "subreport" and the "datasource"

samples.

 

I hope this helps.

Teodor

Further to what Teodor wrote...

Remember to set the parameter class to "java.lang.Object". Then cast it

to the appropriate Type.

In my report I pass a HashMap as a parameter.

I've got a scriptlet that uses the HashMap to display totals in the

Summary section of the report.

This might be useful in your case...if so, check out the scriptlet

example, in the samples section.

 

Regards,

Enrico
