Using JDBC to connect oracle

[sachin mesala]

Hi everyone,

I am using oracle 10g, my jdk is 1.4 and my IDE is eclipse and I am trying to connect the oracle data base with the following code, but I am always getting some exception.

I know time is precious.

 
import java.sql.*;
import java.io.*;
 
public class NotesDB2 {
 
public static void main(String[] args) throws SQLException, IOException{ 
System.out.println ("Loading Oracle driver..."); 
try {
Class.forName ("oracle.jdbc.driver.OracleDriver");
System.out.println("Driver Loading!");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:aks","scott","tiger");
System.out.println("Got Connected" +con);
con.close();
               }

catch(Exception e)
{
e.printStackTrace();
System.out.println("exception occured" +e);
}
 
}
 
   }

What is "some exception"? In which line does it happen?

How are you adding the JDBC driver to the classpath? It apparently isn't part of it.

Hi, I gave in the environment variables , in the user variables I gave variable classpath and the value as . ;C:\oracle\ora92\jdbc\lib\classes12.jar.

But i even tried with the �. Classes14.jar

Still same error.

Are you running this from eclipse? If so, you must add the JAR file containing the driver to the build path.

Right click on the project and select Properties. In the left column select Java Build Path. To the right select the Libraries tab. Click the Add External JARs... button. Search through the file system until you find the JAR file and Click OK.

You may need to rebuild your project to pick up the latest classpath.
