Getting ServiceSelector instead of ComponentSelector

[Andreas Hartmann]

Hi Cocoon developers,

I define a component selector in my roles file:

<role name="org.apache.lenya.cms.ac2.AccreditableManagerSelector"
      shorthand="accreditable-managers"
      default-class="org.apache.avalon.excalibur
                .component.ExcaliburComponentSelector">
  ...
</role>
and set it up in cocoon.xconf:

<accreditable-managers>
  <component-instance logger="lenya.ac.accreditablemanager"
    class="org.apache.lenya.cms.ac2.file.FileAccreditableManager"
    name="file"/>
</accreditable-managers>
But when I try to get the selector in my Java class, I get
an org.apache.avalon.framework.service.WrapperServiceSelector
instead of the ExcaliburComponentSelector. Can anyone tell me
how to avoid this? Is it because my client object is a Serviceable
and not a Composable?
BTW, which class should one use as the default ServiceSelector
instead of the ExcaliburComponentSelector that depends on the
deprecated ComponentSelector?
Thanks in advance!
Andreas
