I realy don't have an idea where my mistake is.
I just can't connect to the Database.

JTDS 1.2
Sql-Server 2000
Sun's Glassfish

JbpmConfiguration.getInstance().createSchema();

- <!-- jdbc connection properties
 -->
 <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
- <!-- property name="hibernate.connection.datasource">JbpmDS</property
 -->
 <property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
 <property name="hibernate.connection.url">jdbc:jtds:sqlserver://192.168.250.70:1433;DatabaseName=JBPM</property>
 <property name="hibernate.connection.username">Me</property>
 <property name="hibernate.connection.password">MyPassword</property>
