JDBC Connection between Unix and SQL Server 2000

Question

I have SQL Server 2000 installed in a pc as a data server and SQL Server 2000 JDBC Drive installed in a Unix machine. Both machines are connected and can ping each other. After setting up the environment data, I ran a test code to test the connection and got exceptions. ( I did the same process between a pc and the data server, it works well.)
Attached are the test code and error message. Hope someone can help me.
******* Test Code ********
import java.sql.*;
* Microsoft SQL Server JDBC test program
public class Test {
public Test() throws Exception {
// Get connection
DriverManager.registerDriver(new
com.microsoft.jdbc.sqlserver.SQLServerDriver());
Connection connection = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://<hostname>","<username>","<password>");
if (connection != null) {
System.out.println();
System.out.println("Successfully connected");
System.out.println();
// Meta data
DatabaseMetaData meta = connection.getMetaData();
System.out.println("\nDriver Information");
System.out.println("Driver Name: "
+ meta.getDriverName());
System.out.println("Driver Version: "
+ meta.getDriverVersion());
System.out.println("\nDatabase Information ");
System.out.println("Database Name: "
+ meta.getDatabaseProductName());
System.out.println("Database Version: "+
meta.getDatabaseProductVersion());
} // Test
public static void main (String args[]) throws Exception {
Test test = new Test();
******* error message ********

Answer 1

If it works from a PC and not from the Unix box then you may have a network issue of some sort, I.E. firewall not letting it through etc.
Try using telnet on the Unix box to see if you can connect to the sql server on the port that the SQL server is listening.
E.G.
telnet server_name 1433
You may need to change the port number to the one that the SQL server is using.
