A User Agent, like a web browser, uses HTTP to request a HTML document
Php Funzione mail()
In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code. On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004 A User Agent, like a web browser, uses HTTP to request a HTML document

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
