Presenting ResultSet into JSP using Struts <logic .. [help]

[CS Lover]

Iam trying to show some results from database - multi results - on JSP page using struts, already did the servlet code to fetch the data as follow :

private void manage(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException{
        ArrayList cats = new ArrayList();
        PrintWriter out = response.getWriter();
        try{
            db.rs = db.statement.executeQuery("select * from cats");
            while(db.rs.next()){
                out.println("z");
                cat cat = new cat();
                cat.setCatname(db.rs.getString("catname"));
                cat.setCatid(db.rs.getInt("catid"));
                cats.add(cat);
            }
            request.setAttribute("cats", cats);
                RequestDispatcher rr = request.getRequestDispatcher("./manage_cat.jsp");
                rr.include(request, response);
        }catch(Exception ex){
            out.println(ex.getMessage());
        }
        
    }

cat.java

package lib;

public class cat {
    private String catname;
    private int catid;

    public int getCatid() {
        return catid;
    }

    public void setCatid(int catid) {
        this.catid = catid;
    }

    public String getCatname() {
        return catname;
    }

    public void setCatname(String catname) {
        this.catname = catname;
    }
}

manage_cat.jsp

<logic:present name="cats">
    <logic:notEmpty name="cats">
        <logic:iterate id="cc" name="cats">
            <bean:write name="cc" property="catid" filter="true"/>
            <br/>
        </logic:iterate>
    </logic:notEmpty>
</logic:present>

Blank Page !
no output at all :D

I tried to print variable ${cats} and it seems it already have objects = records in db ..

So, i dun know i think manag_cat.jsp has something wrong or maybe i should do or configure xml files ?
