Hi Ranjan,
Geronimo includes castor 1.0.5. I'm not positive, but I think it will =
probably be in one of your parent classloaders. So, if you require =
castor 1.1, you'll want to hide castor from your application. A =
deployment plan like the following should do that:

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<web-app xmlns=3D"http://geronimo.apache.org/xml/ns/j2ee/web-1.1" =
xmlns:dep=3D"http://geronimo.apache.org/xml/ns/deployment-1.1" =
xmlns:naming=3D"http://geronimo.apache.org/xml/ns/naming-1.1">
  <dep:environment>
    <dep:moduleId>
      <dep:groupId>org.mygroup</dep:groupId>
      <dep:artifactId>MyApp</dep:artifactId>
      <dep:version>1.1</dep:version>
      <dep:type>car</dep:type>
    </dep:moduleId>

    <dep:hidden-classes>
      <dep:filter>org.exolab</dep:filter>
      <dep:filter>org.castor</dep:filter>
    </dep:hidden-classes>
  </dep:environment>
</web-app>

To deploy, something like:

./bin/deploy.sh deploy <your-webapp.war> <your-xml-deployment-plan>

No guarantees that this will actually alter the behavior of your app... =
May need more information... But let's start by using a single version =
of castor...
