Struts2: how to display an Hashmap<Integer, Object> in jsp?

I'm using struts2. Through my action, I get a Hashmap from a Resultset of java:

ArrayList<HashMap<Integer,Object>> customer = new ArrayList<HashMap<Integer,Object>>();
if(!(finalQuery.equals(""))){
    ResultSet rsFinalQuery = conn.createStatement().executeQuery(finalQuery);
    ResultSetMetaData md = rsFinalQuery.getMetaData();
    int columnCount = md.getColumnCount();
    while (rsFinalQuery.next()){
         HashMap<Integer,Object> row = new HashMap<Integer,Object>();
         for(int i=1; i<=columnCount; ++i){           
             row.put(i,rsFinalQuery.getObject(i));
         }
         biReport.add(row);
    }
}

This is my action class:

public class Actionclass implements SessionAware {
    private Data db;
    private Map<String, Object> session;
    ArrayList<HashMap<Integer,Object>> customer = new ArrayList<HashMap<Integer,Object>>();

    public String execute() {
        db = (Data) session.get("db");
        this.customer = (ArrayList<HashMap<Integer, Object>>) 
                                   db.illustrateReport(this.reportID).get(1);

        return "success";    
    }

    public ArrayList<String> getColumnNames() {
        return columnNames;
    }

    public void setColumnNames(ArrayList<String> columnNames) {
        this.columnNames = columnNames;
    }

    public ArrayList<HashMap<Integer, Object>> getCustomer() {
        return customer;
    }

    public void setBiReport(ArrayList<HashMap<Integer, Object>> biCustomer) {
        this.customer = customer;
    }

    @Override
    public void setSession(Map arg0) {
        this.session = arg0;
    }
}

And this is my jsp:

<html>
<head>
</head>
<body>
<TABLE>       
<TR>
<s:iterator value="customer">
            <option value='<s:property value="value" />'></option> 
        </s:iterator>    
        </TR>     
</TABLE>
</body>
</html>

Now my issue is how can I display the table stored in my HashMap in jsp as a table using struts? I'm not using beans or HTTPservlet and I don't want to have java code in my jsp.

Would be great if you could help!

I finally solved it. This is the right code in the jsp file:

<tr>
    <s:iterator value="customer">
        <s:iterator value="top">
            <td><s:property value="value"/> </td>
        </s:iterator>    
    </s:iterator>
</tr>

Thank you everybody for your help!
