Where to place my .jar in SoapUI directory

Hi,

Looking forward to access java code using SoapUI (free version), but failing to do so. Listing below the 'java code + Groovy Script' and steps i followed, it would be great if I can be guided on this

1. Create code in java using eclipse
package com.sumit;

public class access {

public String access1(){
return "Sumit Baliyan";
}
}

2. Created jar of it
3. Copied jar file in 'lib' folder of SoapUI
4. Now Launched SoapUI
5. Write below code in Groovy Test Step
import com.sumit.*

access ac = new access()
def b = ac.access1()
log.info b
6. Run code and I get this error
groovy.lang.MissingMethodException: No signature of method: Script8.access() is applicable for argument types: (com.sumit.access) values: [com.sumit.access@cc0596]

Note: When i access same jar file in another java program using eclipse it works fine, below is the java code to use jar file code

import com.sumit.access;
public class HelloWorld {
public static void main(String[] args) {
access ac = new access();
String b = ac.access1();
System.out.println(b);
}
}
