How to get login crenditials(Result) from the MBO in a js file

Question

Hi Experts,
    I got a table from oracle db, and i have deployed it and MBO is generated.
That table contains the login credentials which i am giving in the login page.
      I have created a login page with user id and password when i am trying to login by using the credentials which i have registered earlier the credentials are being checked in the table and it should return me yes or no if yes i have to move to next screen if no i should display some alert . My problem is that i am not knowing how to get that verified credentials and display them in my code. I am writing this line of code in java script and i am unable to know, how to handle the data after being checked from the MBO .. please help me out of this ..

Hi Lokesh,
You can write an object query for checking the credentials details.
Right click mbo>Attributes>Object query>Add
Add 2 parameters, give some name like usernameParam and passwordParam
Map these parameters to respective fields like username and password(from MBO)
Generate object query
     e.g. select x.username, y.password from ABC where x.username=:usernameParam and      y.password=:passwordParam
select Return type"as single object""
(assuming username and password are the parameters defined in the mbo ABC.)
redeploy mbo
call this object query to Login button and do all required mappings
For verification, if details are/not available in backend
You have to write some piece of code in customBeforeNavigateForward
e.g.
hwc.customBeforeNavigateForward = function(screenKey, destScreenKey) {
if(destScreenKey="Employee" && screenKey=="Start"){
//Here Employee is the MBO name
alert("test");
var message = getCurrentMessageValueCollection();
alert("test1");
var itemList = message.getData("Employee");
alert("test2");
var items = itemList.getValue();
var noOfItems = items.length;
alert("noOfItems="+noOfItems);
if(noOfItems==0){
alert("Invalid input");
return false;
