Spring + Hibernate + Sql Server connection failing

I am getting the following error when I am using a combination of Spring, Hibernate and SQL Server.

19:17:09,137 ERROR [org.hibernate.tool.hbm2ddl.SchemaValidator] (MSC service thread 1-8) HHH000319: Could not get database metadata: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host falmumapp20/testdb, port 1433 has failed. Error: "null. 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.".

It could not be just a TCP IP problem, because if I work without Spring, I am able to connect to SQL Server using hibernate.

Below is my applicationContext.xml

<!-- Resource Definition -->
<!-- Data Source Connection Pool -->

And here is my Hibernate Configuration file -
