Connect DB2 using Struts, Spring and Hibernate

I integrate struts, spring and Hibetnate together. When I tried connecting to DB2 :

    <property name="hibernateProperties">               
        <value>hibernate.dialect=org.hibernate.dialect.DB2Dialect</value>       
    </property>
</bean>

There are errors

The SQLCODE=-1031, SQLSTATE=58031 indicates that the database directory can't be found on the database server's filesystem.

See IBM's documentation on this error for more information.

Why are you using a driverClassName of com.ibm.db2.jcc.DB2SimpleDataSource instead of com.ibm.db2.jcc.DB2Driver?
