    Remoting from unsigned applet - ClassLoader security excepti

    fatbatman Novice

      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;

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

      Thanks in advance
