A developer wants to customize the Struts configuration file to support form field validation. What needs to be enabled to make the Store Struts application aware of the Validator framework?

  1. CustomPlugin

  2. ValidatorPlugIn

  3. FormValidationPlugin

  4. DefaultValidationPlugin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ValidatorPlugIn is the Struts plugin that integrates the Apache Commons Validator framework into a Struts application. It must be configured in struts-config.xml to enable declarative form validation rules, which the framework then processes automatically when forms are submitted.

The recommended method for retrieving and displaying error messages passed to a view from a controller command is to use a:

  1. StoreErrorDataBean

  2. ResourceBundle

  3. TypedProperty exception data

  4. error view name
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

StoreErrorDataBean is the recommended IBM WebSphere Commerce mechanism for passing error information from controller commands to views. It provides a structured way to access error messages and associated properties in JSP pages, following the framework's MVC pattern better than direct ResourceBundle or exception access.

Declaring EnableViewState="false" at page level will make a Textbox not to retain it's value between postbacks.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Setting EnableViewState="false" at the page level disables ViewState for all controls on that page, meaning TextBox values will not be retained between postbacks. Without ViewState, controls revert to their default values on each postback unless values are manually restored.

Which of the following statements describe generic building blocks

  1. A building block is a package of functionality defined to meet the business needs

  2. A building block has published interfaces to access the functionality

  3. A building block may be assembled from other building block

  4. A building block may have multiple implementations

  5. All of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Building blocks are modular packages of functionality that serve business needs, have defined published interfaces, can be composed from other blocks, and may have multiple implementations. All these characteristics are fundamental to the building block concept in enterprise architecture.

Which programming constructs can be grouped within a package?

  1. Cursor

  2. Trigger

  3. Sequence

  4. View
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PL/SQL packages can group related program units including procedures, functions, cursors, and variables. Option A (Cursor) is correct - cursors CAN be declared in a package specification. Triggers (B), Sequences (C), and Views (D) are standalone schema objects that CANNOT be part of packages.

We can create how many struts config file in an struts application?

  1. Only One

  2. Only Two

  3. As many we needed

  4. Zero
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Struts applications can have multiple configuration files to organize different modules or functional areas. The framework allows developers to create as many struts-config.xml files as needed for better modularity and maintainability. You are not limited to a single configuration file.

Multiple choice technology architecture

Frameworks can be defined in number ways, in a nutshell, these are widely applicable set of reusable code. Frameworks can also be expressed as below except

  1. An abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code, thus providing specific functionality

  2. A special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined Application Programming Interface

  3. A collection of resources to generate the code to achieve a generic functionality

  4. A template to show how things should be done consistently
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Options A, B, and D describe valid framework characteristics: abstractions with selective override, wrapped in APIs, and template-like consistency. Option C is incorrect - frameworks are code themselves, not resource collections that generate code. Frameworks provide executable code, not code generators.

Which of the below is a least relavant question while choosing a framework ?

  1. Whether framewoks has been deveoped using the coding standard that your organization follows

  2. What level of modularity will the framework provide and support?

  3. What development rules will the framework enforce?

  4. What will the learning curve be for application developers to learn the framework?
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When choosing a framework, factors like modularity (B), development rules enforced (C), and learning curve (D) are critical considerations. However, whether the framework was built using your organization's specific coding standards (A) is largely irrelevant - frameworks are built by vendors/communities with their own standards. You adapt to the framework's conventions, not the other way around.

Link / Delink Button in CIM application is found in

  1. Launch Pad Toolbox

  2. Global alerts Toolbox

  3. Customer Profile Toolbox

  4. My folders Toolbox

  5. Open Windows Toolbox
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Link/Delink button is located in the Customer Profile Toolbox within the CIM application. This placement is logical because the function deals with changing customer account responsibility and ownership, which are core customer profile management activities. CSRs access it when modifying account ownership structures.

In order to implement a custom UI component in JSF, what does the renderer class extend from?

  1. javax.faces.renderer.Renderer

  2. javax.faces.render.Renderer

  3. javax.faces.render.Render

  4. javax.faces.renderer.Render
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To implement a custom UI component in JSF, the renderer class must extend javax.faces.render.Renderer. This base class provides the framework for encoding and decoding component markup. Note the package structure is javax.faces.render, not javax.faces.renderer, making option B correct and A incorrect.
