Scriptlet Issue

[ziden]

 Hello there everyone.

Im having a little issue using a pre-made scriptlet, and i belive this is related to classpathing.

 

This is the dir path to the scriptlets:

C:\DesenWeb\Acad\acad\WEB-INF\classes\pckAcadRelatorios\Scriptlets

 

this is the classpath ive added into ireport options

 

C:\DesenWeb\Acad\acad\WEB-INF\classes\

 

then , i added the scriptlet as:

pckAcadRelatorios.Scriptlets.HeadingsScriptlet

 

it finds the scriptlet to compile the report.

 

i also add the scriptlet using a parameter REPORT_SCRIPTLET like this:

HeadingsScriptlet myscriptlet = new HeadingsScriptlet();

        parameters.put("REPORT_SCRIPTLET", myscriptlet);

 

But then, during the report i have the following:

 

<printWhenExpression><![CDATA[(pckAcadRelatorios.Scriptlets.HeadingsScriptlet)($P{REPORT_SCRIPTLET}).addHeading("ShipCountryGroup")]]></printWhenExpression>

 

When i run the application that creates the PDF, it gets me the following error:

 

Error evaluating expression : 

        Source text: (pckAcadRelatorios.Scriptlets.HeadingsScriptlet)($P{REPORT_SCRIPTLET}).addHeading("ShipCountryGroup")

 

Anything am i doing wrong ? Ive tryed adding the wholeclasspath, no deal, tryed many things couldnt make this work. Any ideas ?

 

thanx for any attention !

It may not be your whole issue, but what I can say:

First, do not include the REPORT_SCRIPTLET parameter; you should only add the class name as the Report Scriptlet on the report properties; Jasper will create the scriptlet when needed;

Second, this code is wrong: (pckAcadRelatorios.Scriptlets.HeadingsScriptlet)($P{REPORT_SCRIPTLET}).addHeading("ShipCountryGroup")

This way you are casting to the scriptlet class the result of the 'addHeading' call. Rewrite it like this: $P{REPORT_SCRIPTLET}.addHeading("ShipCountryGroup")

Third, 'printWhenExpression' must evaluate to a boolean, telling if the field should be displayed (true) or not (false). 'addHeading' souds like a method that do the actual heading addition, so it should be in the 'expression' field.
