Basic example java program connecting to Oracle Database using jdbc driver. 1) make sure your java enviroment is properly set. 2) create java source file testOrajdbc.java
//testOrajdbc.java
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.OracleDataSource;
class testOrajdbc
{
public static void main (String args[])
throws SQLException
{
OracleDataSource ods = new OracleDataSource();
//oracle coordinates:schema name, password, hostname/ip, db port and SID
ods.setURL("jdbc:oracle:thin:pbs01/pbs01@10.12.8.3:1521/CUST01");
Connection conn = ods.getConnection();
// Create Oracle DatabaseMetaData object
DatabaseMetaData meta = conn.getMetaData();
Statement stmt = conn.createStatement();
// gets driver info:
System.out.println("JDBC DRIVER VERSION: " + meta.getDriverVersion());
// a select query
ResultSet rset = stmt.executeQuery ("SELECT GLOBAL_NAME FROM GLOBAL_NAME");
while (rset.next()) {
System.out.println("DATABASE NAME = " + rset.getString(1));
}
}
}
3) Make sure your enviromeent include reference to oracle java jdbc library, you simply need to add to your CLASSPATH variable $ORACLE_HOME/jdbc/lib/classes12.jar, in unix HP for example:
export CLASSPATH=$CLASSPATH:/opt/oracle/product/10.2.0/db_1/jdbc/lib/classes12.jar
4) Compile the java program, the output should be the executable file testOrajdbc.class.
$ javac testOrajdbc.java
5) Run the java program testOrajdbc.class anc check the output:
$ java testOrajdbc
