SQL Server Express connection error (with Hibernate, Java-based web app, and Tomcat)
I am trying to resolve a database connection problem while trying to setup a Java-based web application.
There is a working Java-based web application (that uses Hibernate and MS SQL Server Express as a database, and Apache Tomcat as a web server).
I am trying to setup a copy of that web site on another computer (for development).
That another computer already has Apache Tomcat and the SQL Server Express installed, and I mad sure that both computers use the same version of Java.
I backed up the database from the working site and restored it on the new machine.
Then I created the war file on the working machine and expanded it on the new machine.
I made sure the database's setup, configuration, and user's login info is identical on both machines. The hibernate.properties files are identical on both machines (except the machine's name).
However the web application fails to be displayed, and Tomcat's log files show the database connection errors.that appear when the Tomcat service is being started, such as
"Login failed for user 'myUser'."
The hibernate.properties file contains these lines:
**************************
hibernate.connection.url=j
hibernate.connection.drive
hibernate.connection.usern
hibernate.connection.passw
hibernate.dialect=org.hibe
**************************
The errors from the catalina_xxx.log file are below (between the lines):

Again, the application is working on another machine, and the setup is identical (at least, I cannot see the difference).

Can you telnet to that address and port from the machine you're trying to run it on?

I am trying to access the site locally, from the same machine.
I can use the working site also locally, from the working machine.
Both machines are development machines.
On the new machine, if I try to display the web site, it is starting but fails when it tries to use DB data.
I don't have telnet on that machine.

I don't know about SQLEXPRESS but on standard SQL Server, I have a similar Hibernate config, but I always have to enable the SQL Server TCP port first. I use "SQL Server Configuration Manager" from the start menu and under SQL Server Network Configuration, enable TCP/IP, then set Listen all and IPall to port 1433
MySql must have granted permissions to connect from the host (machine) you're currently connecting from.

Oops sorry - wrong DB!. Nonetheless, make sure you have permission to connect from that host

I set it up exactly as on working machine: under SQL Server Network Configuration, enabled TCP/IP, and also enalbed TCP/IP under SQL Native Client Configuration.
1433 port is specified under SQL Native Client Configuration.- it is setup that way and works on another machine,

Your sqljdbc.jar (or whatever the source fource driver jar name is) is deployed with your web app or is it in Tomcat common lib?
It doesn't look like a missing jar, it looks like a permissions problems, but since I don't use that driver, I use the standard Microsoft one, I cannot say.

CEHJ, the user is setup as a database owner on that machine.
However, I would like to test a DB connection.
How can I test a DB connection? The tool that I am using, the SQL Server Management Studio Express, uses a Windows authentication, so username and password are not needed to connect to the database
