A report with Scriplet does not run on Jasper Server

[chsam27]

I am new to Jasper reporting and I have a report with a simple scriplet that only return a string. When previewing it with Jasper studio 6.5.0, I was able to see the results but when I try deploy the same report on my local jasper server, it throws the error:

Caused by: java.lang.ClassCastException: <class> cannot be cast to net.sf.jasperreports.engine.JRAbstractScriptlet
    at net.sf.jasperreports.engine.scriptlets.DefaultScriptletFactory.getScriptlet(DefaultScriptletFactory.java:109)
    ... 178 more]]

I am running the server on Glassfish 4.1.1, included the scriplet jar file in the lib folder and changed the import in the scriplet according to https://community.jaspersoft.com/wiki/classcast-exception-when-running-report-containing-scriptlet

Below is the scriplet:

import net.sf.jasperreports.engine.*;public class DemoScriplet extends JRDefaultScriptlet{        public String getHello() throws JRScriptletException{        return "This is from a scriplet!";    }}[/code]

Has anyone encountered this issue?

Hey, I would suggest following this video tutorial for scriptlets in JasperServer:

In your case I'd try to upload scriptlet as a report resource instead of adding it to lib.
