Hibernation2.1.1

When I call new Configuration() in servlet init() method,it throws java.lang.ExceptionInInitializerError. I look up the hibernate source code
and found that it seems that in Environment class when it call System.getProperties() it throws java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write).

I have tried 2 case:
(1) put the hibernate.properties(or hibernate.cfg.xml) in WEB-INF/classes directory.
(2) not put any hibernate property files(hibernate.properties or hibernate.cfg.xml) in WEB-INF/classes directory.
both cases failed when I call new Configuration().

I don't know what cause the System can not get properties.

the exception trace as follows:

Hi,



Looks like you have a security policy on your server which is peventing the reading of a file (the hibnerate configuration file). Change the security policy to allow this.
