The backend array is passed to the frontend <script>

Create an array of integers in the background

import java.util.ArrayList;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class JsonAction extends ActionSupport {

    private static final long serialVersionUID = 1L;

    public String execute() throws Exception {

        ActionContext context=ActionContext.getContext();
        ArrayList<Integer> list=new ArrayList<Integer>();
        for(int i=0;i<12;i++)
            list.add(i);
        context.getSession().put("list", list);
        return SUCCESS;
    }

}

The foreground uses the jstl standard tag library to obtain array objects

<c:set var="list" value="${list }" scope="session" />

Use EL expression to assign list object to javaScript object

<script language="JavaScript">
var arrayList=${list};
</script>
