Sending Hibernate Objects to a Java Web Start client, I've the following error :

Code:
Caused by: java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks)

   at java.security.AccessControlContext.checkPermission(Unknown Source)
   at java.security.AccessController.checkPermission(Unknown Source)
   at java.lang.SecurityManager.checkPermission(Unknown Source)
   at java.lang.reflect.AccessibleObject.setAccessible(Unknown Source)
   at net.sf.cglib.CodeGenerator.defineClass(CodeGenerator.java:195)
   at net.sf.cglib.CodeGenerator.define(CodeGenerator.java:175)
   at net.sf.cglib.MethodProxy.create(MethodProxy.java:124)


Visibly a problem with cglib proxy ? Any idea ?

Have you set your application to request all privileges in the JNLP File?

All jars are signed.

In JNLP, I've this :

Code:
   <security>
      <all-permissions/>
   </security>

Well this is clearly a missing reflection permission as you can see here:

Code:
   at java.lang.SecurityManager.checkPermission(Unknown Source)
   at java.lang.reflect.AccessibleObject.setAccessible(Unknown Source)

You have to dig into Security Managers, however i think all-premissions should be sufficient ...

I found some interesting things about JWS at :

http://lopica.sourceforge.net/faq.html


I added this in my static main :
Code:
System.setSecurityManager(null);

now it's ok...
