RE: using jt400 in a java applet

[Mike Cunningham <mcunning@xxxxxxx>]

Well it didn't take as long as I though. The error was on reflect permissions so I added this grant clause to the local policy file and it worked

permission java.lang.reflect.ReflectPermission "suppressAccessChecks";

Subject: using jt400 in a java applet

Has anyone ever used the IBM supplied jt400.jar in a java applet application that is sent to the client and executed from the PC?  I have a java application that will run from my PC but when I deploy it as an applet it fails with a permissions error.  It is acting like the jt400.jar files is trying to run outside the JRE and is being denied permission.
