I have been trying to connect netbean service for database explorer with Microsoft SQL Server JDBC Driver 3.0 but unsuccessful always.The zipped jdbc driver has two jars I tested it with sqljdbc but it says that is is not compatible with java 1.7 so I tried it with sqljdbc4 and now it shows following error:
I have enable TCP/IP connection to the server.
What is the right way to connect netbean service with sql server 2008?
I got the solution to this problem actuall you should use the port 57634 for TCP/IP connections. Well you can change the port if you want by going to :
Configuration Manager -> Protocols for SQL SQLEXPRESS > Properties of TCP/IP. In the IP Addresses tab, set the TCPPort in section IPAll to 1433.

currently, I am facing some odd behavior.
I have a Java EE Web Application that I am deploying to a wildfly server. This Java EE Application needs a database to which we need to connect via vpn. We are using OpenVPN. When I am using SSMS I have no problems connecting to the database. When I am using pure JDBC, there also is no problem.
But if I am creating a datasource in wildfly (and I am using the exact same jdbc connection url) it does not working. I am using the wildfly admin ui and click the test-button.
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host 10.1.115.51, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
I mean, the stack trace is pretty clear. However, the connection should be possbile as I connect via ssms and pure jdbc. Just wildfly datasource is not working.
Furhtermore, I have installed a MS SQL Server on the same mashine the wildfly is running on and using this MS SQL instance the datasource is working fine.
The jdbc url connection url is the following:
jdbc:sqlserver://< ip >:1433;databaseName=projdat;user= ** ;password= **
I have compared the jdbc url connection urls multiple times. Both in the pure jdbc and in the datasource they are the same.
Does anybody have any ideas? Is possible that I need to configure openvpn in a special way that wildfly can connect or do I need to configure Wildfly to be able to connect via vpn. Or do I have to configure the MS SQL Server in special way?
Version of MS SQL Server: 12
Version Wildfly: 19.0.0.Final
SQL Server driver: mssql-jdbc-8.2.2.jre8.jar
I apreciate any hint or advise.
Apparently, I was using an older version of Wildfly (in fact, it was wildfly 16). After I upgraded to Wildfly 19, it is now working. However, I have no clue why it was not working with wildfly 16.
I am using MyEclipse professional and trying to connect with the MS SQL SERVER 2016, i am using the jar file sqljdbc4-4.0 and driver
“class name= com.microsoft.sqlserver.jdbc.SQLServerDriver”
My connection URL is jdbc:sqlserver://hamdan:1433;databaseName=DWProject
where hamdan is the SQL server name, after giving the credentials i got the error of error while performing database login with the mysqlserver driver: the driver couldn't establish a secure connection to SQL server by using secure socket layer(SSL) encryption. Error java.lang.runtimeException, could not generate DH keypair.
However i have also set Force Encryption to "NO" in the protocol for sql server's properties in sql server configuration.
when i am changing the jar with the jar present on this link https://www.microsoft.com/en-us/download/details.aspx?id=11774 which is jdbc 6.0 and using jar for jre 8 which is sqljdbc42, i get error of driver class not found while using new database connection driver.
Any help will be highly appreciated, i am on this from more than one day,
I am new to eclipse.
This is the problem in windows 10, it encrypts the link between eclipse and SQL Server, so you should use latest myeclipse or try in different OS
i'm trying to connect to a newly installed SQLServer instance by my java application using jdbc.
When i try to open a connection the server return this error:
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'sa'.
Error Stack trace:
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'sa'. at

I've already enabled "SQL Server and Windows Authentication mode" option.
I also tried to connect to the database server with SquirreL but i had the same problem, but with SQL Server Management Studio i can connect to the db.
I have a SQLServer 2008 R2 express, jdk 6u41 and sqljdbc4.jar JDBC connectors.
I've tried the same application in an environment with SQLServer 2008 R2 express, jdk 6u33 and sqljdbc4.jar JDBC connectors and it work fine.
Are there some SQL server configuration that i need to modify?
I think, you have configured the SQL Server in Windows Authentication mode on the time of installation but, changing the settings in the program would not change it from Windows Authentication mode.
Can you do one thing? Remove the SQL Server 2008 and all related programs from your machine and install a fresh copy, this time with SQL Server Authentication. It will work...
I have a local MS SQL Server and I am trying to connect to it using JTDS in java. Here is the connection string:
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433/stock","sa","password");
And the server properties:
name: USER-PC\SQLEXPRESS
root directory: c:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL
I am getting a Exception in thread "main" java.sql.SQLException: Network error IOException: Connection refused: connect error.
How can I remedy this?
Check the following:
You have enabled mixed mode security, i.e. so you can connect with username/password (rather than using Windows authentication)
The TCP/IP protocol is enabled. Open SQL Server Configuration Manager, then in SQL Server Network config select Protocols and Enable TCP/IP.
Try passing just one String to getConnection using this format:
DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433/stock;instance=SQLEXPRESS;user=sa;password=password")
If you are using this format (naming the instance) then the SQL Server Browser service needs to be running (in Services). If this is greyed out then the Service is probably disabled, so enable it and then start it.
Port 1433 is the port used by the default instance. You're using SQLEXPRESS, which is a named instance. Your connection string should include something like:
sqlserver://localhost\SQLEXPRESS
SQL Server Browser service is disable by default. If you're developing .Net app, you do not need to start SQLBrowser, but if you're using JTDS in java, you will need it started.
I am using sqljdbc4.jar in the Build path of eclipse project.
I am trying to connect to SQL Server 2008 in a java program
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost:1433;" +
"databaseName=sis;user=sample;password=sample;";
connection = DriverManager.getConnection(connectionUrl);
But I am getting the following error.
The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect
I tried the following
Firewall off
Enabled TCP/IP in SQL Server configuration manager --> CLient protocols
SQL Server browser service is also running
Please let me know what other things should I try.
Thanks
Firewall off which way, this way??? open/enable port localhost:1433
run cmd and paste
netsh firewall set portopening protocol = TCP port = 1433
name = SQLPort mode = ENABLE scope = SUBNET profile = CURRENT
2/ change Sql Server authentication from
Windows authe... to Sql Server and Windows authentification (Mixed mode)
3) your version is SQL Server 2008 or SQL Server 2008 Express, if Express, then search on downloaded package (contains excelent help inc examples) how to connect Express on Localhost, there is difference localhost\sqlexpress
here and here and here
4) no idea how to connected, there are TCP/IP and Names Pipes too
EDIT:
5) in Management Studio you have to add new User (SQL autenthification) and assign to the decision Database (whatever or Model too) is there ??? aren't you
