Hi, I am trying basic examples of Hibernate. I am getting the following error while open the database connection.

I am using the hibernate-cfg.xml file as:

<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="hibernate.connection.url">jdbc:hsqldb:hsql://localhost</property>
<property name="hibernate.connection.username">sa</property>
<property name="connection.password"></property>
<property name="connection.pool_size">1</property>
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">create</property>
<mapping resource="com/web1/emp/Employee.hbm.xml"/>

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