[jboss-user] [JBoss Getting Started Documentation] - Getting AccessControlException from Applet trying to call EJ
I am getting the following exception while trying to access EJB deployed on JBoss 4.0.3SP1
from an Applet:
| java.lang.ExceptionInitializerError
| at org.jboss.proxy.SecurityInterceptor$3.run(SecurityInterceptor.java:87)
| ......
| ......
| Caused by:java.security.AccessControlException:access denied
(java.util.PropoertyPermission org.jboss.security.SecurityAssociation.ThreadLocal read)
| .....
|
The exception is thrown from the line "inBox = inBoxHome.create();" in the
following block of code:
| /**
| *
| * @return a InBoxBean object
| * @throws java.lang.Exception
| */
| public InBox getInBoxBean() throws Exception
| {
| InBox inBox = null;
| try
| {
| Object ref = null;
| try
| {
| //look up jndi name
| ref = _context.lookup("InBoxBean");
| }
| catch (Exception ex)
| {
| System.out.println("_context.lookup('InBoxBean') failed with:
"+ ex);
| //look up jndi name again
| ref = _context.lookup("InBoxBean");
| System.out.println("_context.lookup('InBoxBean')
succeeded:");
| }
| //then cast to Home interface
| InBoxHome inBoxHome = (InBoxHome)PortableRemoteObject.narrow(ref,
InBoxHome.class);
| // use Home interface to create remote interface
| inBox = inBoxHome.create();
| }
| catch (Exception e)
| {
| throw e;
| }
| return inBox;
| }
|
The only way I have been able make this work is by running the Java Plug-in on the client
with security manager with the following policy:
| grant {
| permission java.util.PropertyPermission
"org.jboss.security.SecurityAssociation.ThreadLocal", "read";
| permission java.lang.RuntimePermission
"org.jboss.security.SecurityAssociation.getPrincipalInfo";
| permission java.io.SerializablePermission "enableSubstitution";
| };
|
Is there a way to make this work without have to do anything special on the client
plug-in.
Thanks,
Rajeev
