[jboss-user] [Remoting] - Remoting from unsigned applet - ClassLoader security excepti

[fatbatman]

Hi,

I need to try and get JBoss remoting (the latest version from cvs) working in an unsigned applet, as quickly as possible :)

I first got a security exception from the code in org.jboss.remoting.Version that checks the system property for the remoting version e.g. System.getProperty(PRE_2_0_COMPATIBLE).  I've hard coded(hacked) this to the values I require, that's ok for now.


I've now come across something else though that looks a bit more involved;
java.lang.reflect.InvocationTargetException

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

	at org.jboss.remoting.transport.http.TransportClientFactory.createClientInvoker(TransportClientFactory.java:38)

Does anyone have any suggestions for how I might quickly get around this, or is not possible without significant work? 

Thanks in advance

James
