Scriptlet in groovy?

[harry.clarkknovalent.com]

Can I write a scriptlet in Groovy? I need to call some complicated Java in the iReport event model that scriptlets uses, at afterDetailEval and other spots. I want to make the Java available to non-programmers without having them write a Java scriptlet and make a jar. Can I put the Java call in a Groovy scriptlet? I need 3 lines, to get a field from a query, format it, and assign it to a report variable:

 

date = (java.math.BigDecimal)getFieldValue("T1_CAEJDT")

s1 = DateFormat.toString(date)

setVariableValue("invoiceDate", s1)

 

When I put this in the scriptlet editor it tries to compile it even if I set language=groovy

 

Is there a way to use the first 2 lines in an expression, without the last line, which now is the expression value on the report? Again, i'm trying to provide Java code without burdening non-programmers. Thanks.

I can call the Java from an expression, passing the field to be converted as an argument:

 

((net.sf.jasperreports.engine.VanguardDateFormat).vanguardToString($F{T1_CAEJDT}))

 

The Java goes into a jar, which the user has to install, but otherwise needn't bother with it. Good boy, Jasper. Have a bone.

It works in iReport but not in JasperServer. I've added a class to a package

 

net.sf.jasperreports.engine.VanguardDateFormat

 

and put the jar in the webapps/jasper/lib dir with the groovy jar. The class is found in iReport but not in JasperServer:
