hi,
this is the code :
public class TableBean {
Connection con ;
Statement ps;
ResultSet rs;
private List perInfoAll = new ArrayList();
public List getperInfoAll() {
int i = 0;
try
con = DriverManager.getConnection("url","root","root");
ps = con.createStatement();
rs = ps.executeQuery("select * from user");
while(rs.next()){
System.out.println(rs.getString(1));
perInfoAll.add(i,new perInfo(rs.getString(1),rs.getString(2),rs.getString(3)));
i++;
catch (Exception e)
System.out.println("Error Data : " + e.getMessage());
return perInfoAll;
public class perInfo {
String uname;
String firstName;
String lastName;
public perInfo(String firstName,String lastName,String uname) {
this.uname = uname;
this.firstName = firstName;
this.lastName = lastName;
public String getUname() {
return uname;
public String getFirstName() {
return firstName;
public String getLastName() {
return lastName;
ADF table code:
<af:table value="#{tableBean.perInfoAll}" var="row"
binding="#{backing_Display.table1}" id="table1">
<af:column sortable="false" headerText=""
align="start">
<af:outputText value="#{row.firstName"/>//---> Jdeveloper 11g doesn't allow me to use this.. it says firstName is an unknown property..
</af:column>
</af:table>
Please tell me is this the way to do it.. or is it a must to use the DataCollection from the data controls panel...
Thanks...
