Could not connect to oracle8.1.5

[Andreas Reckmann]

Hi,

I try to establish a connection to oracle 8.1.5.
My entry in the data-sources.xml is:

        <data-source
                name="STP data-source"
                class="com.evermind.sql.ConnectionDataSource"
                location="jdbc/DefaultDS"
                pooled-location="jdbc/DefaultPooledDS"
                xa-location="jdbc/xa/DefaultXADS"
                ejb-location="jdbc/stp"
                url="jdbc:oracle:thin:@localhost:1521:stp"
                connection-driver="oracle.jdbc.driver.OracleDriver"
                username="stp"
                password="stp"
                schema="database-schemas/oracle.xml"
        />                     

The orionserver starts without errors.

When I try to connect to the database through a bean i get
an EJBException (null) in alle "database"-methods.

When i use orion1.2 with console (java -jar orion.jar -console2)
it is possible to use a datasource and call sql-statements.
I get the error:
E/A-Exception: The Network Adapter could not establish the connection.

Can someone help me. 

Thanks 
   Andreas
