I'm working on my final year project using java swings and jasper reports for reporting.The application including the reports work fine when I run the application in netbeans but when I deploy it to a jar file and then try to execute it using my command prompt I see this huge text of exception.

The following function invokes the jasper report :
public void printReport(String adID){
try {
Map parameters = new HashMap();
InputStream jasperIS =this.getClass().getResourceAsStream("/Reports/AllHoardings.jasper");
User connect=new User();
JasperPrint print=JasperFillManager.fillReport(jasperIS,parameters,connect.getConnection());
JasperViewer.viewReport(print,false);
}catch(JRException je){
System.out.println(je.toString() +" @ line 2043");
}catch (Exception e) { System.out.println(e.toString()); }
}

This error suggests to me that NetBeans is solving your issues with Groovy and Jasper Reports in a way that your JAR file is not. Check to see if there are JARs missing from your JAR manifest that pertain to Groovy. If yes, add them.
