about JDBC

[bridges]

hi everybody.   I have one question of jdbc.   the code is here: ......    String driverName="sun.java.odbc.JdbcOdbcDriver";    String connectionURL="jdbc:odbc:107";//the ODBC dsn is 107    Connection con=null;    Statement stmt=null;      String sqlStatement="SELECT CHANNEL_ID,MPHONENO,MCC_ID,ZSMPHONENO FROM M_SMS_DISTRIBUTION_LIST";    ResultSet rs=null;      try{      /*      * register jdbc class      * where the error happened      */      Class.forName(driverName);         con=DriverManager.getConnection(connectionURL);      stmt=con.createStatement();      rs=stmt.executeQuery(sqlStatement);   there is always a exception throws when register jdbc class . The exception information is: java.lang.ClassNotFoundException: sun.java.odbc.JdbcOdbcDriver  at java.net.URLClassLoader$1.run(URLClassLoader.java:200)  at java.security.AccessController.doPrivileged(Native Method)  at java.net.URLClassLoader.findClass(URLClassLoader.java:188)  at java.lang.ClassLoader.loadClass(ClassLoader.java:297)  at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:286)  at java.lang.ClassLoader.loadClass(ClassLoader.java:253)  at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:313)  at java.lang.Class.forName0(Native Method)  at java.lang.Class.forName(Class.java:120)  at query.OraQuery.performQuery(OraQuery.java:42)  at query.OraQuery.main(OraQuery.java:23) I have set the classpath as c:\jdk1.3.1\lib, I think there must be something else I should do. but what's that?   thanks
