Accessing oracle DB from a java program - question for oracle driver

Question

Hi,
I have Oracle 10 G under vista on my desktop. I am trying to write a simple java program to access/update database tables. I saw in one of oracle example to import 2 packages - namely --- import oracle.jdbc.driver.*; import oracle.sql.*;
Where do I find these 2 packages. Also I read some documentation to download drivers. I would like to use 2 drivers, the thin driver and the OCI driver. Can someone tell me where I can find these drivers and where do I copy these two drivers - so javac and java command can recognize it.
I will greatly appreciate the help. Julia
My program is as follows
(It was working few years ago but things have changed now and I have Vista because my old machine died):
import java.sql.*; // JDBC package
//import com.inet.tds.JDBCRowSet;
import java.util.*;
import oracle.jdbc.driver.*;
import oracle.sql.*;
public class HomeDB
run as follows:
C:\Documents and Settings\MMM>cd \jj
C:\john>set CLASSPATH=.;c:\oracle9i\classes12;%CLASSPATH%
C:\john>javac HomeDB.java
C:\john>java HomeDB
King: 24000.0
Kochhar: 17000.0
De Haan: 17000.0
Hunold: 9000.0
Ernst: 6000.0
Austin: 4800.0
public static void main(String[] argv)throws SQLException
Connection conn=null;
try // may throw a SQLException
conn = getConnection();
doQuery (conn);
catch (SQLException e)
System.err.println(e.getErrorCode() + ": " + e.getMessage());
finally // make sure the connection is closed
if (conn != null) try {conn.close();} catch (SQLException e) {};
//out.close(); // close PrintWriter stream
private static Connection getConnection() throws SQLException
String username = "scott";
String password = "tiger";
String url = "jdbc:oracle:thin:@localhost:1521:newora";
// "jdbc:oracle:thin:@localhost:1521:COCKYJOB";
Connection conn = null;
String driver = "oracle.jdbc.driver.OracleDriver";
try {
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
} catch ( ClassNotFoundException cnfex ) {
System.err.println(
"Failed to load JDBC/ODBC driver." );
cnfex.printStackTrace();
}catch (Exception e){
e.printStackTrace();
//DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
conn = java.sql.DriverManager.getConnection(url,username,password);
conn.setAutoCommit(false);
return conn;
private static void doQuery (Connection c) throws SQLException
// statement to be executed
String query = "SELECT ename, job, mgr FROM EMP";
Statement st = null;
ResultSet rs = null;
try // make sure the close statements are executed (in the finally block)
// create the statement
st = c.createStatement();
// execute the query
rs = st.executeQuery(query);
// process results
while (rs.next())
// get the employee last name
String eName = rs.getString("ename");
String eJob = rs.getString("job");
String eMgr = rs.getString("mgr");
System.out.println("Emp Name:" + eName +
"Job: " + eJob +
"MGR: " + eMgr);
finally // make sure the close statements are executed
// close the result set if it exists
if (rs != null) try {rs.close();} catch (Exception e) {};
// close the statement if it exists
if (st != null) try {st.close();} catch (Exception e) {};

Answer 1

You can download the drivers from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html.
Note that oracle.jdbc.driver is desupported after 10.2, http://forums.oracle.com/forums/ann.jspa?annID=201, so you might want to consider using a DataSource to provide Connections.
