DeployManager in G-Jetty says "No configurer for module type: war registered"

[Shiva Kumar H R]

I am calling below code from within PlanCreator:
        DeploymentFactory factory = new DeploymentFactoryWithKernel(
PortletManager.getKernel());
        DeploymentManager deploymentManager =
factory.getDeploymentManager("deployer:geronimo:inVM",
null, null);
        DeploymentConfiguration deploymentConfiguration =
deploymentManager.createConfiguration(webDeployable);

And this is failing in Geronimo-Jetty by saying (the same code however works
in Geronimo-Tomcat):
    ERROR [DisplayPlanHandler] No configurer for module type: war registered
    javax.enterprise.deploy.spi.exceptions.InvalidModuleException: No
configurer for module type: war registered
        at
org.apache.geronimo.deployment.plugin.jmx.JMXDeploymentManager.createConfiguration
(JMXDeploymentManager.java:311)
        at
org.apache.geronimo.console.configcreator.JSR88_Util.createDeploymentPlan
(JSR88_Util.java:300)

Am I missing some configuration?
