Re: jSimpleBug: SimpleSwarmBug3

[Pietro Terna]

        Hi Duncan,

        the problem arises from lispAppArchiver (line 34 in 
StartSimpleBug.java) which is not able to find the SimpleBug.scm file.

        Are you using an IDE environment to run the code? If you simply 
run it from the bash shell with javaswarm StartSimpleBug may be the problem 
disappears.

        I'm waiting for your reaction before eploring other possibilities.

        Pietro
