无法使用jdbc连接到SQL Server 2008

Question

I'm trying to connect to a sql server with JDBC in java.

My server uses a windows authentication.

I use this code:

String url = "jdbc:sqlserver://MYPC\\MYSERVER;databaseName=MYDB;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url);

In my classpath i have the file: jtds-1.3.1.jar and sqljdbc4.jar

And i have a VM argument:

-Djava.library.path="SQLPATH\jtds\x64\SSO"

When i run the code, i have this exception:

com.microsoft.sqlserver.jdbc.SQLServerException: Unable to connect to the host MYPC

Do you know what is wrong?

Answer 1

The URL syntax is jdbc:sqlserver://[serverName[\\instanceName][:portNumber]][;property=value[;property=value]]

Did you try to ping your host using ping command ? Or try with IP address.

Answer 2

If //MYPC\\\\MYSERVER is a network path, I'd imagine it needs to look like this:

\\MYPC\\MYSERVER

Of course, if the SQL Server 2008 instance is setup as the default instance, the \\\\MYSERVER portion isn't necessary.
