Put these jars in lib directory of your EAR or define such a lib
directory in the deployment descriptor and move the jars there. Have
you tried it already?

Doh, completely forgot about this nifty features. Thanks Kevan! I
think it's time to have a wiki page about how to deploy apps with jars
that are in different version than those provided by Geronimo.  It's
an excellent approach to get more involved in Geronimo development.
Anyone fancy looking into it?

I think you may need to be more specific about your dependencies and  
what problems you're running into...

Placing jars in your ear's lib directory will make their classes  
available to the ear classloader, but system classloaders will still  
have priority over your ear classloader.

You'll still need to invert classloading or hide classes for this to  
work. Parent classloaders will still have priority... Something like

     <hidden-classes>
       <filter>javax.xml.ws.</filter>
     </hidden-classes>

or

    <inverse-classloading>

Sounds like you've tried using inverse-classloading. What problems  
have you encountered?
