thank you for the code send
i see deploymentDescriptor as a string attribute of mbean
org.apache.catalina.core.StandardContext
I also see com.sun.xml.rpc.tools.wsdeploy.DeploymentDescriptorParser class
but I am unable to locate the javadoc documentation for DeploymentDescriptor
could you display link for DeploymentDescriptor
thanks,
Martin
