Basic data source example in java

How do you create a DataSource?
To create a data source from a service, run the Data Source Configuration Wizard and choose the Service data-source type.
This action is just a shortcut to the Add Service Reference dialog box, which you can also access by right-clicking the project in Solution Explorer and selecting Add service reference..
How to create a DataSource in Java?
To create and deploy a DataSource object, you need to perform these tasks:
1Create an instance of the appropriate DataSource implementation.
2) Set the properties of the DataSource object.
3) Register the object with the Java Naming and Directory Interface (JNDI) naming service..

How to get database name from DataSource in Java?
One way to get the name of the underlying database you have connected with is by invoking the getDatabaseProductName() method of the DatabaseMetaData interface.
This method returns the name of the underlying database in String format..
How to get DataSource from connection in Java?
Use the DataSource. getConnection method to obtain the connection.
You can use one of the following forms of the getConnection method: getConnection(); getConnection(String user, String password);.
How to use DataSource in Java?
From your system administrator, obtain the logical name of the data source to which you need to connect.
Create a Context object to use in the next step.
The Context interface is part of the Java Naming and Directory Interface (JNDI), not JDBC..
What is BasicDataSource in Java?
public class BasicDataSource extends Object implements DataSource, BasicDataSourceMXBean, MBeanRegistration, AutoCloseable.
Basic implementation of javax. sql.
DataSource that is configured via JavaBeans properties..
What is data sources in Java?
A DataSource object is the representation of a data source in the Java programming language.
In basic terms, a data source is a facility for storing data.
It can be as sophisticated as a complex database for a large corporation or as simple as a file with rows and columns..
Why do we need DataSource?
A DataSource object holds the credentials needed to get a connection to the database.
Typically, a DataSource holds a user name recognized by the database server, a password for that user, and various settings to customize any future sessions with the database..
Why use DataSource in Java?
A DataSource object has properties that can be modified when necessary.
For example, if the data source is moved to a different server, the property for the server can be changed.
The benefit is that because the data source's properties can be changed, any code accessing that data source does not need to be changed..
A Data Source object enables JDBC applications to obtain a DBMS connection from a connection pool.
Each Data Source object binds to the JNDI tree and points to a connection pool or MultiPool.
Applications look up the Data Source on the JNDI tree and then request a connection from the Data Source.

For example MySQL JDBC Driver provides basic implementation of DataSource interface with com.mysql.jdbc.jdbc2.optional.MysqlDataSource class and

Create a BasicDataSource object and configure the database. Use setDriverClassName(String driverClassName) method to set the jdbc driver class name. Use setUrl(

Deploying Basic Datasource Objects

The system administrator needs to deploy DataSource objects so that The Coffee Break's programming team can start using them. Deploying a DataSourceobject consists of three tasks:.
1) Creating an instance of the DataSourceclass.
2) Setting its properties.
3) Registering it with a naming service that uses the Java Naming and Directory Interface (JNDI) .

Deploying Distributed Transactions

DataSource objects can be deployed to get connections that can be used in distributed transactions. As with connection pooling, two different class instances must be deployed: an XADataSource object and a DataSourceobject that is implemented to work with it. Suppose that the EJB server that The Coffee Break entrepreneur bought includes the DataSour.

Deploying Other Datasource Implementations

A system administrator or another person working in that capacity can deploy a DataSource object so that the connections it produces are pooled connections. To do this, he or she first deploys a ConnectionPoolDataSource object and then deploys a DataSource object implemented to work with it. The properties of the ConnectionPoolDataSource object are.

Getting and Using Pooled Connections

A connection poolis a cache of database connection objects. The objects represent physical database connections that can be used by an application to connect to a database. At run time, the application requests a connection from the pool. If the pool contains a connection that can satisfy the request, it returns the connection to the application. I.

Using Datasource Objects to Get A Connection

In Establishing a Connection, you learned how to get a connection using the DriverManager class. This section shows you how to use a DataSourceobject to get a connection to your data source, which is the preferred way. Objects instantiated by classes that implement the DataSource represent a particular DBMS or some other data source, such as a file.

What is a basic DataSource implementation?

A basic DataSource implementation produces standard Connection objects that are not pooled or used in a distributed transaction

A DataSource implementation that supports connection pooling produces Connection objects that participate in connection pooling, that is, connections that can be recycled

What is a basicdatasource connection?

Any connection produced by the BasicDataSource object ds will be a connection to the database CUSTOMER_ACCOUNTS

With the properties set, the system administrator can register the BasicDataSource object with a JNDI (Java Naming and Directory Interface) naming service

What is Java DataSource & JDBC DataSource programming?

Java DataSource and JDBC DataSource programming is the way to work with database in our java programs

We have already seen that JDBC DriverManager can be used to get relational database connections

But when it comes to actual programming, we want more than just connections

What is Java DataSource interface?

Java DataSource interface is present in javax

sql package and it only declare two overloaded methods getConnection () and getConnection (String str1,String str2)

It is the responsibility of different Database vendors to provide different kinds of implementation of DataSource interface

Executable Java file format

A Java class file is a file containing Java bytecode that can be executed on the Java Virtual Machine (JVM).
A Java class file is usually produced by a Java compiler from Java programming language source files containing Java classes.
If a source file has more than one class, each class is compiled into a separate class file.

Collections in Java

The Java collections framework is a set of classes and interfaces that implement commonly reusable collection data structures.
