SCRIPTLET uses problem

[mhbashar1]

I m a newbie.Can anybody tell me how to create scriptlet.I tried but it didnt work.I use iReport 2.0.2.What I did was-first going to Edit>Scriptlet editor,I write the following code-

Code:

import net.sf.jasperreports.engine.*;
public class Utility extends it.businesslogic.ireport.IReportScriptlet {
  
/** Creates a new instance of JRIreportDefaultScriptlet */
public Utility() {
}
public String getText()
{
return "Hello world";
}
}

Then I saw that a java file named DemoScriptlet.java is created where I saved my report file.But if I name the class- Utility,then how did iReport name it-DemoScriptlet.java.?Then I first wrote-

" new Utility().getText()" in the expression editor of a text field,then I wrote "$P{REPORT_SCRIPTLET}.getText()" but none worked,it says-

net.sf.jasperreports.engine.JRException: Error compiling report java source files : D:Documents and SettingsTonuMy DocumentsMyProjectMemoRmiReportDemoScriptlet.java

Where was my problem,Can anybody give me a clear idea about SCRIPTLET pls
