83 Advanced Java | JDBC 4 | without using Class forName(-) oracle thin driver | adv java
 
12:36
Advanced Java Tutorail : JDBC 4 0. adv java | Java Database Connectivity JDBC Application to test the database without using Class.forName(-) method. JDBC 4.0 Specification: The important feature of JDBC 4.0 specification is automatic loading of java driver class from java.sql. Driver File available from jar file of jdbc driver i.e. (ojdbc6.jar in oracle 11g). This makes programmers to avoid Class.forName(-) statement in his java application while writing jdbc code. - All the jdbc drivers thar are given based on jdbc 4.0 specification are giving java.sql.Driver File in there jar files, So when these jar files are added to the classpath the driver manager class automatically collects the driver class from java.sql.Driver File, loads the driver class & registers that driver automatically with DriverManager service. ojdbc14.jar (given by oracle 10g) is based on jdbc 3.0 specification so it does not contain java.sql.Driver File . ojdbc6.jar (given by oracle 11g) is based on jdbc 4.0 specification, so it contain java.sql.Driver File as shown below java.sql.Driver------oracle.jdbc.OracleDriver postgresql-8.4-701.jdbc4.jar of posgresql is based on jdbc 4.0 specification, so it contains java.sql.Driver File as shown below java.sql.Driver------org.postgresql.Driver JDBC application to test the connection with oracle database without using Class.forName(-) ===================================================== Step 1) Set the jar to the classpath ( ojdbc6.jar) Step 2) create the jdbc application import java.sql.*; public class WithoutClassForName { public static void main(String[] args) throws Exception { Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "scott", "boss"); Statement st=con.createStatement(); st.executeUpdate("insert into student values(1000,'patil','Omerga')"); } } compile & run

26:23
Advanced Java Tutorial :adv java: JDBC Connection Pool and Its Utilization | java Database connectivity :JDBC Connection Pooling: JDBC Connection pool is a factory that contains set of readily available JDBC connection objects. Using JDBC Connection pool we can make more clients interacting with Database by using minimum JDBC connection objects. JDBC DataSource object represent JDBC Connection pool that means to access connection objects from connection pool we need to use DataSource object. DataSource Object means its the object of a class that implements javax.sql.DataSource interface There are two types of JDBC connection objects: ----------------------------------------------- 1) Direct Connection object: Created by programmer (manually) Ex. Class.forName("oracle.jdbc.driver.OralcleDriver"); Connection con=DriverManager.getConnection("url","user","pass"); 2)Pooled Connection object: It is the object that is collected from JDBC connection pool using JDBC DataSource object. Two types of JDBC connection pools: ----------------------------------- 1) DriverManaged JDBC Connection Pool: (Driver itself maintains connections) -Suitbale for standalone application. -Uses Type 1/2/4/5 drivers directly. -Only few JDBC drivers support this kind of JDBC connection pools ex. Oracle OCI, thin driver 2) Server managed JDBC connection pool: -Suitable for web applicatoin which runs on web/proxy server. -Uses type 3 with type 1/2/4/5 JDBC drivers. -Suitable for 3-tier/n-tier applicatoin which runs on server environment. Example JDBC application on Oracle thin driver to manage the JDBC connection pool for Oracle: ========================================================================= import java.sql.*; import javax.sql.*; import oracle.jdbc.pool.*; public class ConnectionPoolTest { public static void main(String[] args) throws Exception { //create the Empty jdbc datasource object representing driver managed Connection pool for oracle OracleConnectionPoolDataSource ds=new OracleConnectionPoolDataSource(); //give the details to create JDBC connection objects in the above empty datasource connection pool i.e 'ds' ds.setDriverType("thin"); ds.setServerName("localhost"); ds.setPortNumber(1521); ds.setServiceName("orcl"); ds.setUser("scott"); ds.setPassword("boss"); //Upto here JDBC connection pool ready with JDBC connection object //get one JDBC connection object from connnection pool Connection con=ds.getConnection(); // Write the JDBC persistant logic Statement st=con.createStatement(); ResultSet rs=st.executeQuery("select * from student"); while(rs.next()){ System.out.println(rs.getInt(1)+"\t"+rs.getString(2)+"\t"+ rs.getString(3)); } rs.close(); st.close(); con.close(); // --- returns/release the conection object back to JDBC connection pool } }

Aplicação Exemplo - Desenvolvimento Web
 
12:55
Vídeo para mostrar como fazer funcionar no NetBeans uma aplicação WEB simples feita com os frameworks JSF e JPA do JAVA URL da Aplicação no GitHub: https://github.com/Atanes/Projeto_Exemplo_DSD_JSF_JPA.git Não esqueçam de trocar, no arquivo PERSISTENCE.XML, o nome da base de dados para o nome que você criar na sua máquina ou no repositório de dados remoto e o usuário e senha para acesso ao seu banco de dados. Outra observação importante sobre o vídeo é que eu estou usando o banco de dados PostgreSQL e para outros bancos de dados vocês precisam fazer mais algumas alterações no arquivo persistence.xml conforme exemplos abaixo: Para Banco de Dados MySql: property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/nomedobanco" property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" Para Banco de Dados Oracle Thin (11g, 12G, etc.): property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver" property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:nomedobanco" property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect" É preciso colocar a biblioteca correspondente do banco na pasta de bibliotecas do projeto! Vocês podem fazer o download da biblioteca do Oracle em: http://www.oracle.com/technetwork/apps-tech/jdbc-112010-090769.html Para PostgreSQL e MySQL o NetBeans já tem as bibliotecas configuradas e nesse caso é só escolher a biblioteca correta na lista que aparece na opção adicionar biblioteca quando você clica com o botão direito em cima da pasta bibliotecas do projeto.

Lesson - 32 : Hibernate - server side connection pooling in Hibernate
 
25:42
Hibernate – Built-in Connection Pooling in Hibernate: 1. If a java program wants to obtain a connection with a database then java API as provided or JDBC API as provided two ways. A) java.sql.DriverManager class B) javax.sql.DataSource interface 2. If a java program want to get direct connection with the database then we use DriverManager class. 3. The connection returned by DriverManager class is a nonreusable connection. The non reusable connections will increase the burden on a database. 4. To overcome the above problem we got connection pooling technique in java. 5. In connection pooling a group of reusable connections(pooled connections) are stored in a pool and the connections are provided to the clients whenever required. 6. To obtain a connection from a connection pool we use DataSource interface in a java program In hibernate connection pooling mechanism is divided into three types 1. Built-in connection pooling / jdbc connection pooling 2. Standalone connection pooing/Third party connection pooling 3. Server side connection pooling Server-side connection pooling 1. In built in connection pooling and also in a stand alone/third party connection pooling. Hibernate itself creates a connection pool internally in case of this server side connection pooling. Hibernate only obtains a connection from a pool which is configured by the administrator at server side but hibernate does not create a connection pool at server side. 2. Hibernate uses DataSource object is created or configured by the administrator as a mediator , to obtain a connection from the pool. 3. If a java program wants to obtain a connection from the pool then a DataSource object will act as mediator between a java application and a connection pool. Steps to configure a connection pool in glassfish3.x: Glassfish 3.x server is automatically installed along with netbeans 7.x IDE. We can find the glassfish server installed with IDE in c:\program files folde 1. Copy driver jar file i.e ojdbc14.jar into c:\program files\glassfish-3.1.2.2\glassfish\domains\domain1\lib\ext folder. 2. Start the glassfish server write the on command line c:\program files\glassfish-3.1.2.2\glassfish\bin>as admin start-domain domain. 3. Open the browser and type the following request http://localhost:4848. 4. At left side expand resources->expand jdbc->select jdbc connection pool ->click on new ->enter the following details. 1. Pool name : samplepool 2. Resource type : javax.sql.DataSource 3. Database Driver Vendor : oracle->click on next 5. Enter the following three additional properties 1. User : system 2. Password : tiger 3. URL:jdbc:oracle:thin :@localhost:1521:orcl3 -> finish. 6. click on pool name(samplepool)->click on ping button->if ping succeded then the pool is created successfully, otherwise pool is not created. 7. At left side click on jdbc resources->new button->enter JNDI name:oraclejndi->pool name:samplepool->ok. Hibernate Examples Project Github Link : https://github.com/SadaLearningHub1/Hibernate-Projects

Standard Steps to Develop JDBC Application
 
02:01
This video actually shows what JDBC does and how to develop JDBC application by using these standard steps. Basic Components of JDBC:- 1. Driver: It is a translator to convert Java calls into Specific Database calls and Specific Database calls into Java calls. 2. Connection : To convert these calls(Java and DB calls) some connection must be required and that is nothing but Connection. In short, From Java Application to reach Database Connection must be required. 3. Statement: Its purpose is to send SQL Query to the DB under to bring the results from DB to Java Application. 4. ResultSet: It's nothing but set of Results processed in DB. From this ResultSet Java Application can get the result of SQL Query. **Standard Steps To Develop JDBC Application** 1.Load and Register Driver class. -Syntax: Class.forName(“Driver Class Name”); 2. Establish Connection Between Java Application and Database. - Syntax: Connection con=DriverManager.getConnection(“jdbc_url”,”user”,”pwd”); 3. Create Statement Object. - Syntax: Statement st=con.createStatement(); 4. Send and Execute SQL Query and Stored in Resultset. -Syntax: ResultSet rs=st.executeQuery(“select * from Employees”); 5. Process Result From ResultSet. while(rs.next) { Syntax: System.out.println(rs.getInt(1)+” ”+rs.getString(2)+” ”+rs.getString(3)); } Where rs.getInt(1) is the method contains first column of Employee table and its type is integer. Ex.eno is type Int. And same for String Type column 2 & 3 it may be ename & eadd. 6. Close the Connection. Syntax: con.close(); ***A Simple Java(JDBC) Program Using these Standard Steps:**** import java.sql.*; // package for SQL classes public class JdbcDriver { public static void main(String[] args) throws Exception { // Step1: Class.forName(“oracle.jdbc.OracleDriver”); // Step2: Connection con=DriverManager.getConnection(“jdbc:oracle:thin:@localhost:1521:XE”,”root”,”apple”); //Step 3: Statement st=con.createStatement(); // Step 4 & 5: ResultSet rs=st.executeQuery(select * from Employees); while(rs.next) { System.out.println(rs.getInt(1)+” ”+rs.getString(2)+’’ ”+rs.getString(3)); } // Step 6: con.close(); } //closing of main method } // closing of class Note: In this program ,we are using Type 4 Driver i.e We are loading Type 4 Driver. Conclusion: In these steps, Connection, DriverManager, Statement, ResultSet are the classes which are present in java.sql.*; package. So by using these Standard Steps We can Develop any JDBC Application.

As a programmer we are allowed to set the maximum pool size for hibernate built- in connection pool 3. If you want to set maximum pool size then we need to configure connection pool size property in hibernate.cfg.xml file 4. <property name=“hibernate.connection.pool_size”>10</property> 5. The built- in connection pool of hibernate is only for testing purpose, but it should not be used in real time application (production.system) Configurations: <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:xe</property> <property name="hibernate.connection.pool_size">50</property> <mapping resource="Payment.hbm.xml"/> </session-factory> </hibernate-configuration> Hibernate Examples Project Github Link : https://github.com/SadaLearningHub1/Hibernate-Projects
