Yes and no... it could be done in the eclipse.ini,
but I prefer to set this as 
eclipse.product in the config.ini. This is done in EPP by setting the 
eclipseProductId attribute

  <product
    name="eclipse-jee-ganymede-M5"
    eclipseProductId="org.eclipse.platform.ide"
    initialPerspectiveId="org.eclipse.jst.j2ee.J2EEPerspective"
/>

The other attribute initialPerspectiveId might be interesting for you as
well. 
This entry will be added to the platform_customization.ini.
