I wish I knew more about the subject. From what you are saying it looks
like you are also trying to compile Schemas at runtime. If that is the
case, then you will need to enable read access for xbean.jar as well
(even though it is already in the classpath).

Subject: Re: XMLBeans + security manager
I have partially solved this by explicitly giving read access to the
schema jar in the policy (even though it is already in the classpath).
However I now get:
org.apache.xmlbeans.XmlException: Thread main: The 0th supplied input is
not a schema document: its type is N=
Any ideas?
Thanks
PS. The exception I was previously getting (without schema jar read
permissions) was:
