I am running Orion on Linux.
The 'Product' application runs o.k when I use the
hypersonic database. But I get the following error
when trying to use postgreSQL:

"Error reading application-client descriptor. Error
looking up EJBHome. Disconnected.. Unknown command 7"

The data-source.xml looks as follows:

<?xml version="1.0"?>
<!DOCTYPE data-sources PUBLIC "Orion data-sources"
"http://www.orionserver.com/dtds/data-sources.dtd">

<data-sources>
        <!--
                An example/default DataSource that uses an ordinary
                JDBC-driver (in this case hsql) to create the
connections. 
                This tag creates all the needed kinds
                of data-sources, transactional, pooled and EJB-aware
sources.
                The source generally used in application code is the
"EJB"
                one - it provides transactional safety and
connection pooling.
        -->
        <!--
        <data-source
                class="com.evermind.sql.DriverManagerDataSource"
                name="Hypersonic"
                location="jdbc/HypersonicCoreDS"
                xa-location="jdbc/xa/HypersonicXADS"
                ejb-location="jdbc/HypersonicDS"
                connection-driver="org.hsql.jdbcDriver"
                username="sa"
                password=""
                url="jdbc:HypersonicSQL:./database/defaultdb"
                inactivity-timeout="30"
        />
        -->
        <data-source
                class="com.evermind.sql.ConnectionDataSource"
                name="postgresql"
                location="jdbc/postgreDS"
                xa-location="jdbc/xa/postgreXADS"
                ejb-location="jdbc/postgreEJBDS"
                connection-driver="org.postgresql.Driver"
                username="postgres"
                password="xxxx"
                url="jdbc:postgre:./database/postgredb"
                inactivity-timeout="30"
                schema="database-schemas/postgresql.xml"
        />
</data-sources>

Also, I included "postgres" as a user in the
"administrators" group in principals.xml

Also, I include:
default-data-source="jdbc/postgreEJBDS" in
orion-application.xml under deployment-directory.

Is there anything else I need to do? Do I need to do
any clean-up after I run the application using
hypersonic and before re-running it with postgres?

Thanks for your help
