I have a project that uses EclipseLink 2.1.3 under Tomcat 7.

What’s bugging me is that the connection to the server doesn’t persist through all of the app’s life.
For a ServerSession to start I have to access the application manually.

Is there a way to automatically start a ServerSession when the application deploys and keep it running at all times ? So that I can access the application after a long idle time without having to wait ?

Thank you!

EDIT:
I have the following lines in persistence.xml

  <property name="eclipselink.jdbc.read-connections.min" value="5"/>
  <property name="eclipselink.jdbc.read-connections.max" value="10"/>
  <property name="eclipselink.jdbc.write-connections.min" value="6"/>
  <property name="eclipselink.jdbc.write-connections.max" value="12"/>

    Server applications usually use a JDBC connection pool to get connections and reuse them. Depending on the pool you use, you may configure it to keep a given number of connections open.
