Hibernate version: 3

I am using Hibernate 3 in EJB. When I trying to create session factory exception thrown:

com.sun.ejb.containers.EJBLocalObjectInvocationHandler.invoke(EJBLocalObjectInvocationHandler.java:128) ... 33 more Caused by: java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at java.lang.reflect.AccessibleObject.setAccessible(AccessibleObject.java:107) at net.sf.cglib.core.ReflectUtils.getConstructor(ReflectUtils.java:245) at net.sf.cglib.core.ReflectUtils.newInstance(ReflectUtils.java:220) at net.sf.cglib.core.ReflectUtils.newInstance(ReflectUtils.java:216) at net.sf.cglib.core.KeyFactory$Generator.firstInstance(KeyFactory.java:157) at net.sf.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:220) at net.sf.cglib.core.KeyFactory$Generator.create(KeyFactory.java:145) at net.sf.cglib.core.KeyFactory.create(KeyFactory.java:117) at net.sf.cglib.core.KeyFactory.create(KeyFactory.java:108) at net.sf.cglib.core.KeyFactory.create(KeyFactory.java:104) at org.hibernate.impl.SessionFactoryImpl.(SessionFactoryImpl.java:321) ... 41 more

in java.security I enable this library:
grant codeBase "file:/home/work/lib/hibernate-3.0/lib/cglib-2.1.jar" {
permission java.security.AllPermission;
};

path to cglib defined in app server classpath (I am using Sun JS AppServer).

Cglib does not wrapp security sensetive calls in "doPrivileged", wrapp it yourself and grant permissions for your code.
see http://java.sun.com/j2se/1.4.2/docs/api ... ction.html

Code:

public static SessionFactory create() {
         AccessController.doPrivileged(new PrivilegedAction() {
              public Object run() {
                  
                    return buildSessionFactory();

              }
         });
     }

And grant permissions for caller code, jar with "buildSessionFactory" inside:

Code:

grant codeBase "file:/home/work/lib/my.jar" { 
permission java.security.AllPermission; 
};
