I try to use jasper field as an argument of a method which call using scriptlet inside the expression

[KavinduAkash]

I have a scriptlet named MainX_SCRIPTLET. Via this scriptlet able to call divider(String l1, String l2) method. Also, I have 2 fields named tDTO and kDTO, I want to set values of these fields into l1 and l2 parameters of the divider method. And I try to write an expression for the list element as follows using the scriptlet, then I have to face an error. Need a solution?

Expression >>

new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{MainX_SCRIPTLET}.divider($F{tDTO }, $F{kDTO}))[/code]

 

Error >>
