Explain different Java Web Frameworks.

 INTRODUCTION TO JAVA WEB FRAMEWORKS

Frameworks are large bodies of pre-written code to which you add your own code in order to solve a problem. You make use of a framework by calling its methods, inheritance, and supplying callbacks, listeners, or other implementations of the patterns. A framework will often dictate the structure of an application. Some frameworks even supply so much code that you have to do very little to write your application. Three major java web frameworks are briefly discussed below.

Struts: Struts is a Java-based open-sourced framework that helps in developing web application in J2EE. It extends the Java Servlet API and promotes the Model, View, Controller (MVC) architecture. This makes the web applications developed in standard technologies like JSP, JavaBeans, and XML, more maintainable, extensible,and flexible. The framework is designed to streamline the full development cycle, from building, to deploying, to maintaining applications over time. Struts provide various other features to make web development easier for the developers such as POJO forms and POJO actions, Tag Support, AJAX support, easy Integration and many

Spring: Spring is a powerful lightweight application development framework used for Java Enterprise Edition (JEE). In a way, it is a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. The framework in a broader sense can be defined as a structure using which can solve many technical problems. You can say that the Spring Framework is a comprehensive tool for supporting applications using Java programming language. you

. Hibernate: Hibernate is a framework in Java which comes with an abstraction layer and handles the implementations internally. The implementations include tasks like writing a query for CRUD operations or establishing a connection with the databases, etc. Hibernate develops persistence logic, which stores and processes the data for longer use. It is lightweight and an Objection-relational Mapping (ORM) tool, and most importantly open-source which gives it an edge over other frameworks. ORM is a technique that maps the object stored in the database. An ORM tool simplifies data creation, manipulation, and access. It internally uses the Java API to interact with the databases.

What are different steps used in JDBC? Write down a small program showing all steps.

-
 T he fundamental steps involved in the process of connecting to a database and executing a query consist of the following: Import JDBC packages. Load and register the JDBC driver. Open a connection to the database. Create a statement object to perform a query. Execute the statement object and return a query resultset. Process the resultset. Close the resultset and statement objects. Close the connection. These steps are described in detail in the sections that follow. 1. Import JDBC Packages This is for making the JDBC API classes immediately available to the application program. The following import statement should be included in the program irrespective of the JDBC driver being used: import java.sql.*; Additionally, depending on the features being used, Oracle-supplied JDBC packages might need to be imported. For example, the following packages might need to be imported while using the Oracle extensions to JDBC such as using advanced data types such as BLOB, and so on. import o...

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Pure Versus Partial EC

Image
Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online. Partial E-Commerce on the other hand refers to a slightly opposite situation where a business has an online presence, but still has a physical location for the goods and services it sells. For example, Amazon, Walmart, and any other you can think of. you buy the goods online but receive them physically.                   ...
