Hello,
I'm currently trying to get a CORBA (David) object to work as an applet. As a first
step, I use the appletviewer.
My problem is that the applet gets an exception when trying to call another CORBA
object or itself, and the applet's clients also get the same exception:
org.omg.CORBA.BAD_PARAM: org.omg.CfMAF._<IDL_interface>Stub
thrown by <IDL_interface>Helper.narrow()
(where <IDL_interface> is one of my own interfaces' name)
The funny thing is that the applet can deal with CORBA naming service!
In fact, as we see below, there is a ClassLoader issue...
Does anyone have a suggestion?
example/more details
====================
By adding a printStackTrace() in MAFAgentSystemHelper.narrow(), I get the following
trace:
java.lang.ClassNotFoundException: org.omg.CfMAF._MAFAgentSystemStub
