Do you have the same problem with the Microsoft JDBC driver (http://www.microsoft.com/downloads/details.aspx?FamilyId=C47053EB-3B64-4794-950D-
81E1EC91C1BA&displaylang=en) using the code below?
import java.*;
public class Connect{
private java.sql.Connection con = null;
private final String url = "jdbc:sqlserver://";
private final String serverName= "evanbagx620\\sql2007";
private final String portNumber = "4141";
private final String databaseName= "AdventureWorks";
private final String userName = "username";
private final String password = "password";
// Informs the driver to use server a side-cursor,
// which permits more than one active statement
// on a connection.
private final String selectMethod = "cursor";
// Constructor
public Connect(){}
private String getConnectionUrl(){
return url+serverName+":" + portNumber +";databaseName="+databaseName+";selectMethod="+selectMethod+";";
}
private java.sql.Connection getConnection(){
try{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);
if(con!=null) System.out.println("Connection Successful!");
}catch(Exception e){
e.printStackTrace();
System.out.println("Error Trace in getConnection() : " + e.getMessage());

I'm having a problem connecting to SQL-Server 2005 using the JTDS 1.22 JDBC
driver.
This occurs for only one of two SQL-Server 2005 instances I have. The
specifics are:
I have two machines, each loaded with SQL-Server 2005, one a 64-bit Server,
and one a 32-bit Laptop for development/demo purposes. The setups are
similar, but obviously not identical.
Server -
WinXP 64-bit SP2
SQL-Server 2005 64-bit - Windows Authorization (WA) and sa/password logins
SouceForge JTBS 1.22 JDBC driver
Oracle SQL-Developer 1.54 (target app which needs JTBS driver - the MS JDBC
doesn't work)
Laptop -
WinXP 32-bit SP3
SQL-Server 2005 32-bit - Windows Authorization and sa/password logins
SouceForge JTBS 1.22 JDBC driver
Oracle SQL-Developer 1.54 (target app which needs JTBS driver - the MS JDBC
doesn't work)
In short - they are very similar and the PATH's and CLASSPATH's are
virtually identical (save for C:\Program Files and C:\Program Files (x68)
which are altered as needed.on the 64-bit machine).
What works: Both the Server and the Laptop can log into the SQL-Server
64-bit instance on the Server without difficulties using the JTBS driver.
From the Server, I can use both WA and SA/password login, and can use amachine name for either "localhost" or the server-name. From the Laptop, I
can use SA/password login and server-name. The JTBS driver is using port
1433 (default). Also, I can hit the Server database with the SQL-Server
native ODBC driver without difficulty from both machines (as expected).
What doesn't work: Both the Server and the Laptop *cannot* log into the
SQL-Server 32-bit instance on the Laptop using the JTBS driver. From the
Laptop, I've tried using both WA and SA/password login, and have tried using
both the "localhost" and the server-name, all without success. From the
Server, I've tried SA/password login and server-name, again without success.
The JTBS driver is using port 1433 (default). Each time I end up with
"cannot connect to database" errors, presumably from the JTBS driver.
Paradoxically, I can hit the Laptop database with the SQL-Server native ODBC
driver without difficulty from both machines.
This makes no sense to me given that I thought I had set up the SQL-Servers
almost identically, and that I can hit both databases with ODBC, but not
JDBC. One thought is there is some privileging problem, or maybe port 1433
is not the right one.
Any thoughts?
Thanks!
