Answer 1

Hi,
1.I want to validate if the value entered is pure integer
Option 1-
select the component and in the Property Inspector, in the "Core" category select a "Converter" format, select javax.faces.Number, if the user put a string, adf show a dialog error or message error...
Option 2-
or use the Regular expression:-

Option 3-
Frank in his great book 'Oracle Fusion Developer Guide' shows a example using a javascript for input which is allowed only for numbers. You can manipulate for your requirement.
Here is the code:
function filterForNumbers(evt) {
    //get ADF Faces event source, InputText.js
    var inputField = evt.getSource();
    var oldValue = inputField.getValue();
    var ignoredControlKeys = new Array(AdfKeyStroke.BACKSPACE_KEY, AdfKeyStroke.TAB_KEY, AdfKeyStroke.ARROWLEFT_KEY, AdfKeyStroke.ARROWRIGHT_KEY, AdfKeyStroke.ESC_KEY, AdfKeyStroke.ENTER_KEY, AdfKeyStroke.DELETE_KEY);
    //define the key range to exclude from field input
    var minNumberKeyCode = 48;
    var maxNumberKeyCode = 57;
    var minNumberPadKeyCode = 96;
    var maxNumberPadKeyCode = 105;
    //key pressed by the user
    var keyCodePressed = evt.getKeyCode();
    //if it is a control key, don't suppress it
    var ignoreKey = false;
    for (keyPos in ignoredControlKeys) {
        if (keyCodePressed == ignoredControlKeys[keyPos]) {
            ignoreKey = true;
            break;
    //return if key should be ignored
    if (ignoreKey == true) {
        return true;
    //filter keyboard input
    if (keyCodePressed < minNumberKeyCode || keyCodePressed > maxNumberPadKeyCode) {
        //set value back to previous value
        inputField.setValue(oldValue);
        //no need for the event to propagate to the server, so cancel
        //it
        evt.cancel();
        return true;
    if (keyCodePressed > maxNumberKeyCode && keyCodePressed < minNumberPadKeyCode) {
        //set value back to previous value
        inputField.setValue(oldValue);
        evt.cancel();
        return true;
2.I want to check if the value exists in my respective DB You must be having EO or VO if you want to validate with database in that case use the solution suggested by Timo.
Thanks
