How to get database connection in common java class

Question

hi friendz,
plz help me...
I am using JDEV 11.1.2.2.0 version.
my problem is I'm writing common java class which can reuse any application.
in this case when im create database connection like this,
String username = "a";
String password = "b";
String thinConn = "jdbc:oracle:thin:@IP:1521:database";
DriverManager.registerDriver(new OracleDriver());
Connection conn =
DriverManager.getConnection(thinConn, username, password);
conn.setAutoCommit(false);
return conn;
but this statement not working in java class.its working only backing bean.
import oracle.jdbc.OracleDriver;
DriverManager.registerDriver(new OracleDriver());
how can i do that??
hope your help

What is the error message in Java class?
With JDBC 4.0 driver the DriverManager class has added support for the Java SE Service Provider mechanism to the getConnection() and getDrivers() methods using which JDBC drivers may be loaded automatically. The following Class.forName() method is not required to be invoked.
Class.forName(“oracle.jdbc.OracleDriver”);
Only the following is required to obtain a connection.
String url="jdbc:oracle:thin:@localhost:1521:ORCL";
Connection connection = DriverManager.getConnection(url,"oe", "pw");
