Hi,

I am new to Hibernate. I am not able to make connection. Below I placed all code which I have used to make connection to SQL Server 2008 but it's giving below error. Please check my configuration file as well and correct me.

Console Error:
Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Cannot open connection

Please verify the connection properties and check that a SQL Server instance is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port.

Below is code:

hibernate.cfg.xml file configuration:

<hibernate-configuration>

<session-factory>

<!-- Database connection settings -->
<property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=JDBC;</property>
<property name="connection.username">BABU-GOUDA/hp</property>
<property name="connection.password"></property>

<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>

<!-- Names the annotated entity class -->
<mapping class="org.babu.dto.UserDetails"/>

</session-factory>

</hibernate-configuration>

and HibernateTest.java class is:



Please check and tell me where went wrong and what's the problem.

Observing the Stack Trace, I believe, your application is unable to connect to the MS-SQLServer. Please check if TCP connections can be made with the MS-SQLServer at the given port.
