I've found error:
Wrong:
<messageadapter>
<messagelistener>
<messagelistener-type>com.unknown.jee.omf.domain.SimpleOverloadListener</messagelistener-type>
</messagelistener>
<activationspec>
<activationspec-class>com.unknown.jee.omf.ActivationSpecImpl</activationspec-class>
</activationspec>
</messageadapter>
correct:
<messageadapter>
<messagelistener>
<messagelistener-type>com.unknown.jee.omf.domain.SimpleOverloadListener</messagelistener-type>
<activationspec>
<activationspec-class>com.unknown.jee.omf.ActivationSpecImpl</activationspec-class>
[b]</activationspec>
</messagelistener>
[/b]</messageadapter>
<activationspec> inside <messagelistener>, not in <messageadapter>.
