When you start Tomcat or other application servers you should see the connection Pool initialization; a text similar to the following:

OBEROn Platform
Version: 4.1 - Build 0071

-----------------------------------------------------------
Mail Server: localhost
------------------- Opening DB Connection POOL ----------------------
Opening connection [1] to OBEROn DB .....
Connecting to database 'XE' - URL: jdbc:oracle:thin:@127.0.0.1:1521:XE
SQL Connected to database 'XE'
... Local DB connection [1] is ready
Opening connection [2] to OBEROn DB .....
....
Connection successful!
Total DB connections Opened: 10
**************************************************************************
*** Servlet Initialized successfully *** [DB-Build = 0071]
**************************************************************************

If this message is not present, probably you missed to declare in the web.xml file the ServletInitializer servlet:


<servlet>
 <servlet-name>ServletInitializer</servlet-name>
 <servlet-class>com.oberon.ooql.connection.ServletInitializer</servlet-class>
 <load-on-startup>1</load-on-startup>
</servlet>


Without the connection pool initialization the application server will not able to connect to the OBEROn DB
