How Can I use a Variable in Data Controls query. Frank Kindly check...

Question

Hii,
I am using JDeveloper 11g ADF BC.
My Requirement is that I hv a login screen which is taken from [http://blogs.oracle.com/shay/simpleJSFDBlogin.zip].
I hv attached BC in this application. I want to use the login usercode in the next pages after login screen. Next screen contains 3 list items which will be populating based on the user. So I created <af:selectOneChoice> using the BC( Just drag & dropped the column into the page from the data controls). But in the data control i want to use this usercode for passing the condition. Now Data is coming without any condition.
So How can I use the usercode in the Data controls query.
When I tried to display the usercode in the next page it is showing by binding the value. its code is follows
<af:outputText value="#{backing_getUser.uid}"
The program for checking the username & Password is follows.
package login.backing;
import oracle.adf.view.rich.component.rich.RichDocument;
import oracle.adf.view.rich.component.rich.RichForm;
import oracle.adf.view.rich.component.rich.input.RichInputText;
import oracle.adf.view.rich.component.rich.layout.RichPanelFormLayout;
import oracle.adf.view.rich.component.rich.nav.RichCommandButton;
import java.sql.*;
import java.util.List;
import java.util.Map;
import oracle.adf.view.rich.component.rich.output.RichMessage;
import oracle.jdbc.OracleDriver;
public class GetUser {
private RichInputText uid;
private RichInputText pid;
private RichCommandButton commandButton1;
private RichInputText inputText1;
private RichInputText inputText2;
public void setUid(RichInputText inputText1) {
this.uid = inputText1;
public void setPid(RichInputText inputText2) {
this.pid = inputText2;
public RichInputText getUid() {
return uid;
public RichInputText getPid() {
return pid;
public void setCommandButton1(RichCommandButton commandButton1) {
this.commandButton1 = commandButton1;
public RichCommandButton getCommandButton1() {
return commandButton1;
public String login_action() {
// Add event code here...
String user = this.getUid().getValue().toString();
// String pass = inputText2.getValue().toString();
String pid = this.getPid().getValue().toString();
Connection conn;
conn = getConnection();
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery ("SELECT usercode FROM guser where usercode = '"+user.toUpperCase()+"' and pwd=F_TEST('"+pid.toUpperCase()+"')");
if (rset.next()) {
conn.close();
return "good";
conn.close();
} catch (SQLException e) {
System.out.println(e);
return "bad";
public static Connection getConnection() throws SQLException {
String username = "ACCTS";
String password = "ACCTS";
String thinConn = "jdbc:oracle:thin:@SERVER1:1521:G5PS";
DriverManager.registerDriver(new OracleDriver());
Connection conn =
DriverManager.getConnection(thinConn, username, password);
conn.setAutoCommit(false);
return conn;
public void setInputText1(RichInputText inputText1) {
this.inputText1 = inputText1;
public RichInputText getInputText1() {
return inputText1;
public void setInputText2(RichInputText inputText2) {
this.inputText2 = inputText2;
public RichInputText getInputText2() {
return inputText2;

Hi,
I didn't look at the example, but if you want to secure your application then you should use container managed security. Read this .
Anyway, you could add this before return "good"; in your login_action()
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("username", user);Then, you can access this from anywhere in the application by using #{sessionScope.username}.
