Subject CVSSource
Date Thu, 21 Apr 2005 15:14:49 GMT
Hello,

I am trying to use the CVSSource on Cocoon 2.1.5.

What I tried is adding to cocoon.xconf:
(1 line context information)

    <component-instance
class="org.apache.cocoon.components.source.impl.ModuleSourceFactory"
name="module"/>
    <component-instance name="cocodoco-cvs"
class="com.anwrt.cocoon.cvssource.source.CVSSourceFactory">
      <hostname>cvs.apache.org</hostname>
      <repository>/home/cvspublic</repository>
      <module>xml-cocoon2/src/documentation</module>
      <username>anoncvs</username>
      <password>anoncvs</password>
      <!-- optionnal hierarchy refresh period (in seconds, defaults to 600) -->
      <refresh-period>3600</refresh-period>

      <!-- optionnal commit message expression (sitemap syntax) -->
      <commit-message-expr>{request-param:cvs-message}</commit-message-expr>
    </component-instance>
  </source-factories>

I did this because I did not find a "source-handlers" section.

The problem: StackOverflowException.
The repeating stack:

If I understand what is happening, cocoon is trying to initialize
everything recursively. IOW, the getVariable method of CVSSource needs
something from the component manager which is not ready until it is
fully initialized... but what?

Any hints? Thank you very much for your help.
