Question 1

Per wants to connect to a datasource using JDBC. What is the best way to do this?

A. He will need to download and install the relevant JDBC drivers and write SSJS or Java to call the required methods.

B. Write a LotusScript or Java agent and call it from Client-Side JavaScript, as he would have done in traditional Domino web applications.

C. He must use a third-party tool like DECS or LEI.

D. The necessary JDBC drivers will come pre-installed with Domino. He just needs to write SSJS or Java to call the required methods.

Question 2

Jeremy wants all of the dijit.Dialog boxes in his application to call a client side JavaScript function called "validateForm" whenever they are hidden. What is the best solution?

A. Whenever he initializes a new dijit.Dialog, add an onHide event like so:
var dialog = new dijit.Dialog({
onHide: validateForm
}
);

B. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

C. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

D. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

E. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

F. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new dijit.Dialog();

G. In the "Close" or "Cancel" button of each dialog add a call to validateForm in the onClick event.
