I Using Apache derby in embedded network server mode through hibernate.


                  <property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect" />

                  <property name="hibernate.hbm2ddl.auto" value="update" />

                  <property name="hibernate.show_sql" value="false" />

                  <property name="hibernate.format_sql" value="false" />

                  <property name="connection.autocommit" value="true"/>

                  <property name="hibernate.connection.url"

                        value="jdbc:derby://localhost:8011/MY_DB;create=true" />

                  <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.EmbeddedDriver" />


When I start my application I pass to the JVM the following properties to start the network server:

-Dderby.drda.startNetworkServer=true -Dderby.drda.portNumber=8011


Everything works fine.

But if at the same time if I’ll open a new CMD and start my application from a different JVM, the connection of first application will be reset.


I need to support using two or more applications that can reference MY_DB.

The Embedded Server Mode should support this:  http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#Embedded+Server


What I’m doing wrong ?


Please help…
