    JDBC connection problem

    979522
      Hello.
      I'm trying to establish a connection with Oracle DB (11g, JDK: 1.5)
      Source code:
      ________________________________________________________________
      import java.sql.*;
      import oracle.jdbc.*;
      
      class Conn {
        public static void main (String args []) throws Exception
        {
      
              Connection conn = DriverManager.getConnection
                   ("jdbc:oracle:thin:@//localhost:1521/SERVER", "v", "QAZwsx111");  }
      }
      ________________________________________________________________

      javac Conn.java // succeeds
      java Conn // throws Exception:
      __________________________________________________________________
      Exception in thread "main" java.lang.NoClassDefFoundError: Conn
      Caused by: java.lang.ClassNotFoundException: Conn
      __________________________________________________________________

      I have tried many CLASSPATH definitions but nothing helps.
      However, JDeveloper succeeds with connection (perhaps it uses its own libaries)

      Help me please solve this, I'v stucked with it for two days.
      Btw, sorry for the newbie post.
