Connecting to SQL Server 2k using Thin drivers

Hi all,
I am new to java. I need to write an applet which takes input from user and
updates the database. I wrote a trusted applet but i was unable to access
network resources. Then i wrote thread inside an apllet which is working fine.
When I use JDBC-ODBC driver, its taking DSN from client machine and not from
server. Can i specify Server DSN?
When I use Thin Drivers, I am getting ClassNotFoundException in the
following line
Driver d =
(Driver)Class.forName("com.microsoft.jdbc.sqlserve r.SQLServerDriver").newInstance();
Here is my code, please let me know if anything is wrong
try {
Driver d =
(Driver)Class.forName("com.microsoft.jdbc.sqlserve r.SQLServerDriver").newInstance();
con =
DriverManager.getConnection("jdbc:microsoft:sqlser ver://wks01:1433";User=test;Password=pass");
}
catch(ClassNotFoundException e) { e.printStackTrace();}
catch(Exception e){ e.printStackTrace();}
finally {
try {
Statement stmt = con.createStatement();
stmt.executeUpdate("INSERT INTO lms " + "VALUES ('" + NewApplet.this.lmsVar
+ "')");
if(con != null)
con.close();
}
catch(Exception e) { }
}
Also, If i specify Database Server name as Server name will it resolve from
client

Hello,
Just to make sure we're on the same page, I'm assuming a "thin" JDBC driver
to mean a Type 4 driver. The Microsoft JDBC driver is one such driver.
For the ClassNotFoundException, you must ensure that the JDBC driver .jar
files are listed appropriately in your CLASSPATH environment variable or
properly specified in the "-cp" command line parameter of java.exe. The
server name used in the URL to make the connection will either specify the
database server name and instance port number OR the database server name
and SQL Server instance name:
jdbc:microsoft:sqlserver://dbserver\\instance1;User=test;Password=pass;
jdbc:microsoft:sqlserver://dbserver:1456;User=test;Password=pass;
If the SQL Server instance is a default instance, then you can simply use
port 1433 (unless you have changed this default value explicitly) as you
have indicated in your sample above.
Hope that helps!
