Question

I’m trying to connect a Java program with MS SQL SERVER 2012 but Java throws the exception: java.lang.ClassNotFoundException.

I understand that the problem often is a result of that the CLASSPATH is not set up correctly for the driver. I have followed the directions from Oracle to add a CLASSPATH, but I still get the same exception. When I type “echo %CLASSPATH%" in the command prompt I get a correct response. What have I missed?

Code:

import java.sql.*;
public class JDBCTest {
    public static void main(String[ ] args) throws SQLException {
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
        } catch(Exception e) { 
            System.out.println("Can't find database driver: " + e);
        }
    }
}

The runtime environment for your application may not contain the appropriate jar file.
The path that you have checked is only for your console environment. The application classpath is different from this.
