Iterate Map on JSPX

Question

I appreciate if someone can help me to iterate Map on jspx via ADF components.
package view.mb;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import oracle.adf.model.BindingContext;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.binding.BindingContainer;
import view.vo.EmployeeVo;
public class PageController {
public PageController() {
private Map<String, EmployeeVo> employees = null;
public void loadData() {
employees = new HashMap<String, EmployeeVo>();
empList = new ArrayList<EmployeeVo>();
for (int i = 1; i < 10; i++) {
EmployeeVo vo = new EmployeeVo();
vo.setId("" + i);
vo.setName("username-" + i);
vo.setEmailId("username-" + i + "@yahoo.com");
employees.put("" + i, vo);
} // for (int i=0; i<10; i++)
refreshObject("employeesIterator");
private void refreshObject(String iterName) {
BindingContainer bindings =
BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBind = (DCIteratorBinding)bindings.get(iterName);
iterBind.executeQuery();
public void setEmployees(Map<String, EmployeeVo> employees) {
this.employees = employees;
public Map<String, EmployeeVo> getEmployees() {
return employees;

Answer 1

Hi,
delete previous binding for employee. add an iterator and a tree binding for that iterator in pageDef
suppose you name the treebinding as employees.
AFAIK you are trying to display id,name,emailid for each row... is that right ? then go through my following code.
<af:iterator value="#{bindings.employees.rangeSet}"
var="row">
<tr>
<td>
<af:outputText value="#{rowVo.id}"/>
</td>
<td>
<af:outputText value="#{rowVo.name}"/>
</td>
<td>
<af:outputText value="#{rowVo.emailId}"/>
</td>
</tr>
</af:iterator>Regards,
Santosh.
