J'ai un pb pour récupérer une variable depuis une scriplet.

J'ai écrit la scriplet qui me retourne simplement une chaîne de caractères.
Le code de la scriptlet

import net.sf.jasperreports.engine.*;

public class TestScriptlet extends net.sf.jasperreports.engine.JRDefaultScriptlet {
//La valeur qui sera affichée dans le rapport
private String montantChiffreLettre = null;
/** Creates a new instance of JRIreportDefaultScriptlet */
public TestScriptlet() {
montantChiffreLettre = "test";

}

//Variable qui sera utilisée ans le rapport
public String getMontantChiffreLettre() {

return montantChiffreLettre;
}


/** Begin EVENT_AFTER_COLUMN_INIT This line is generated by iReport. Don't modify or move please! */
public void afterColumnInit() throws JRScriptletException
{
super.beforeColumnInit();
}
/** End EVENT_AFTER_COLUMN_INIT This line is generated by iReport. Don't modify or move please! */
/** Begin EVENT_AFTER_DETAIL_EVAL This line is generated by iReport. Don't modify or move please! */
public void afterDetailEval() throws JRScriptletException
{
super.afterDetailEval();
}

public void afterGroupInit(String groupName) throws JRScriptletException
{
super.afterGroupInit(groupName);
}
/** End EVENT_AFTER_GROUP_INIT This line is generated by iReport. Don't modify or move please! */
/** Begin EVENT_AFTER_PAGE_INIT This line is generated by iReport. Don't modify or move please! */
public void afterPageInit() throws JRScriptletException
{
super.afterPageInit();
montantChiffreLettre = "test";
}
