Hi,

I want to keep on concatinating a field from the detail section to a variable and display this variable in some other section. How can i achieve this?

Hi,

 

A nice solution to this would be to use custom

implementations of the JRIncrementer and JRIncrementerFactory interfaces along with the

"incrementerFactroryClass" associated with a report

variable.

 

With these, you'll basically teach JasperReports how

to make a sum out of String elements.

 

To learn how to implement these interfaces, take a look

at the existing implementation that are in the source files

of JasperReports and deal with day-to-day incrementations like sums, average, min, max, etc.

 

Or, you could simply use scriptlets like shown in the

provided "scriptlet" sample where we concatenate city names.

 

I hope this helps.

To teodor: Much to complicated for users who can make reports but no Java.

 

Suggestion, make this possible through a new tag in JRXML
