This error could have occurred when the variable debug_ which you have binded in the class Tracefile has not been initialised or provided with a value in your tcl script. I received a similar error when trying to run a tcl script over an agent (MyAgent) I have been using. The error was something like: warning: no class variable Agent/Myagent::myval_ I solved this problem by including the following line in my tcl script: Agent/MyAgent set myVal_ 0 - --- ManojKumar.A --- Blog: http://getch.wordpress,com Mailing list guidelines: http://goo.gl/xC874 -- View this message in context: http://old.nabble.com/no-class-variable-Tracefile%3A%3Adebug_-tp21948143p31317010.html Sent from the ns-users mailing list archive at Nabble.com.

You havent taken an effort to do so. A mailing list should be the ultimate place to post your queries when you haven't got the solution from other means.
