If you prefer to use jboss connection  pool,
1- define your datasource in jboss, ( you can find sample data source definitions in jboss.org)
2- change your hibernate.cfg to use the defined datasource.

Then you have to decide whether you like to use CMT or BMT transaction management ( in normal scenarios it's better to use CMT - because everything is handled by the container ), so you have to add the following entries to your hibernate.cfg as well ( in CMT ):

<property name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>

your error information doesn't provide enough info, but
it seems your connection  properties are wrong !? like connection URL
(port, ...) If you're using Microsoft's JDBC Driver for SQLServer
change it to someother available ones (just google search, I'd used
some other SQL Server JDBC driver called jta-[something].jar )
and make sure your SQLServer is configured properly at the right port.

Could you provide us with the full stack trace of the exception you're getting
as well as some
information regarding your data source settings?
