SOAP Webservice in Java

  Web Service Components

There are three major web service components.

  1. SOAP
  2. WSDL
  3. UDDI

SOAP

SOAP is an acronym for Simple Object Access Protocol.

SOAP is a XML-based protocol for accessing web services.

SOAP is a W3C recommendation for communication between applications.

SOAP is XML based, so it is platform independent and language independent. In other words, it can be used with Java, .Net or PHP language on any platform.

WSDL

WSDL is an acronym for Web Services Description Language.

WSDL is a xml document containing information about web services such as method name, method parameter and how to access it.

WSDL is a part of UDDI. It acts as a interface between web service applications.

WSDL is pronounced as wiz-dull.

UDDI

UDDI is an acronym for Universal Description, Discovery and Integration.

UDDI is a XML based framework for describing, discovering and integrating web services.

UDDI is a directory of web service interfaces described by WSDL, containing information about web services.

SOAP Web Services

SOAP stands for Simple Object Access Protocol. It is a XML-based protocol for accessing web services.

SOAP is a W3C recommendation for communication between two applications.

SOAP is XML based protocol. It is platform independent and language independent. By using SOAP, you will be able to interact with other programming language applications.

Advantages of Soap Web Services

WS Security: SOAP defines its own security known as WS Security.

Language and Platform independent: SOAP web services can be written in any programming language and executed in any platform.

Disadvantages of Soap Web Services

Slow: SOAP uses XML format that must be parsed to be read. It defines many standards that must be followed while developing the SOAP applications. So it is slow and consumes more bandwidth and resource.

WSDL dependent: SOAP uses WSDL and doesn't have any other mechanism to discover the service.

  JSP - Java Server Pages Technology   Java Server Pages (JSP) technology allows you to easily create web content that has both static and dynamic components. JSP technology makes available all the dynamic capabilities of Java Servlet technology but provides a more natural approach to creating static content. The main features of JSP technology are as follows: ·          A language for developing JSP pages, which are text-based documents that describe how to process a request and construct a response ·          An expression language for accessing server-side objects ·          Mechanisms for defining extensions to the JSP language JSP technology also contains an API that is used by developers of web containers. Using this technology developer can design UI for client (browser) as well as business logic for communicating server. A JSP file contains HTML, JavaScript, CSS & Java codes.   JSP  technology is used to create web application just like Servlet technology.

Data Types in PL/SQL

  PL/SQL - Data Types In this chapter, we will discuss the Data Types in PL/SQL. The PL/SQL variables, constants and parameters must have a valid data type, which specifies a storage format, constraints, and a valid range of values. We will focus on the  SCALAR  and the  LOB  data types in this chapter. The other two data types will be covered in other chapters.   S.No Category & Description 1 Scalar Single values with no internal components, such as a  NUMBER, DATE,  or  BOOLEAN . 2 Large Object (LOB) Pointers to large objects that are stored separately from other data items, such as text, graphic images, video clips, and sound waveforms. 3 Composite Data items that have internal components that can be accessed individually. For example, collections and records. 4 Reference Pointers to other data items. PL/SQL Scalar Data Types and Subtypes

What is JDBC ?

Introduction JDBC stands for Java Database Connectivity. It is a Java API that defines how a Java program can connect and execute queries with a database. It is a part of the Java Standard Edition platform, from Oracle Corporation. JDBC API uses JDBC drivers to communicate with different types of databases. There are four types of JDBC drivers: JDBC-ODBC Bridge Driver, JDBC Native Driver, JDBC Network Protocol Driver, and JDBC Thin Driver The most commonly used type is the Thin Driver, which is database-specific and platform-independent The Statement interface is used to create SQL basic statements in Java it provides methods to execute queries with the database.

What is Hibernate in java ?

Introduction to hibernate  Hibernate ORM is an object–relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate is a Java framework used for the development of Java application to interact with the database. It is an open source, lightweight, Object Relational Mapping tool. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence.  Java Hibernate is an object-relational mapping tool allowing the mapping of object-oriented models to relational databases for  web applications  by providing a framework. Mapping of entities in a Java class to tables created in a database and mapping from Java data types to  SQL data types  is one of the primary functions of Hibernate. You can also retrieve data using Hibernate. It is the alternate for developer from manually handling the database using JDBC. Hibernate is an open-source object-relational mapping (ORM) fr
