Connecting a groovy application to SQL server Express

I was following the tutorial below but there must be some significant steps where knowledge, that I don't have, is being assumed.

http://padcom13.blogspot.co.uk/2011/01/setting-up-sql-server-2008-express-to.html

below is the setup in my datasource.groovy

username = "sa"
password = ""
url = "jdbc:sqlserver://localhost:1433;databaseName=Sandpit"
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
dialect = "org.hibernate.dialect.SQLServerDialect"

and below is the error popping up on run app command 

ERROR context.GrailsContextLoader  - Error executing bootstraps: 
Error creating bean with name 'transactionManagerPostProcessor': 
Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException:

Been working on this a couple of days without seeing my app run..... any advice?

We are doing the same thing like you. Therefor, we have the sqljdbc.jar in our /lib -directory.

In our DataSource.groovy we have then:

dbCreate = "update" // one of 'create', 'create-drop','update'
username = "dbo"
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
url = "jdbc:sqlserver://devdb02:1433;databaseName=my_database;"

I remember that just the .jar is not enough, I think you need to install a small part into your windows/unix-directory e.g. from here:

http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774

(that's also needed if you maybe use PHP with MSSQL)

The root cause is Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'

That's because your driver is missing in the classpath. In the case of SQL Server you need to copy the jar to the lib folder.

In other cases like MySQL you can declare as a maven dependency.
