I'm using Hibernate to connect to an SQL Server 2008 named instance.
This works if I use the default instance name but not when using the "named" instance.
config.setProperty("hibernate.connection.url","jdbc:sqlserver://127.0.0.1\INSTANCE_NAME:1433;databaseName=DB_NAME;autoReconnect=true");
Any ideas why this happens?
Thanks in advance.
A named instance does not listen on port 1433, only the default instance
You should not need the :1433 bit
Default vs named instances is mentioned in the MS JDBC info on MSDN

I need to connect to SQL Server from Glue via JDBC, can someone advise how to specify instance name in JDBC.
The following connection string works for the default instance however I need to pass instance name to it.
jdbc:sqlserver://xxx-cluster.cluster-xxx.us-east-1.rds.amazonaws.com:1433;databaseName=employee
This looks correct as your endpoint contains the instance address only.
What problem you are facing?
Can you change a SQL port at the database level rather than the instance level? Trying to force an application using SQL at the database level. General question only thanks.
No, the port cannot be changed at a database level, assuming you are using SQL Server. It can be changed at only the server/instance level.
Know that the instance is serving connections. Once you connect to the server, then you choose the database and then the objects under that database. The port of entry is the server and that's where the port is defined.
In case you haven't run into this doc, check it out: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/configure-a-server-to-listen-on-a-specific-tcp-port?view=sql-server-ver15
Is there a way with the SQL Server (2008 or newer) to fake a connection to a named instance so that it appears to look like the default instance to applications?
I have an application that has many connection strings hard coded to a default instance, and I would like to run it on a named instance.
Thanks in advance for any help on this.
You can do this using an alias to create a common name for clients that can point to different instances:

I've never liked the User instance when attaching a database in linqpad. It only seemed to work for the SQLExpress edition not the full one. Now it's being depreciated in SQL Server 2012 (which is now released), do you intend to use the new localdb feature instead or in addition to the user instance?
LINQPad unticks the 'User Instance' checkbox by default if your server name doesn't contain "SQLEXPRESS". However, it does not disable the checkbox because it cannot be certain that that instance is not a SQL Express instance simply by the name.
LINQPad will still need to support user instances because it must still support SQL Express 2008 and SQL Express 2005.
Does it let you connect to a SQL 2012 localdb if you enter "(localdb)\v11.0" into the Server box?
Say I have a Server named "MyServerABC", on which I have Sql Server 2005 installed with a Default Instance. Thus I can always connect to my sql server just by specifying "MyServerABC".
Now, I change my server's name to "MyServerDEF". Will I now be able to connect to the sql server by just specifying "MyServerDEF"?
Are there any holes in my thinking? Is it really that simple, or are there additional steps involved, or potential problem areas?
Yes, that's correct from a remote connection view if you change MyServerABC to MyServerDEF in connection strings.
There are a few more things to consider (##SERVERNAME will not change by default for example) so have a look here: How to: Rename a Computer that Hosts a Stand-Alone Instance of SQL Server
Often, you'd use MyServerPermanentAlias as a network DNS entry too so the actual server name is irrelevant.
If you use the machine name to connect, you will have to change your connection strings. If that's what you are looking for, then yes, it's that easy - no additional steps needed.
That's why you can also use (local) or just "." as shortcuts for the local machine.
