JADE cannot find agent


I'm new to JADE and am having a bit of trouble loading agents.

I created a new IntelliJ project and added "jade.jar" and "commons-codec-1.3.jar" (I'm using JADE 4.1.1) in "Dependencies" and ticked the export boxes (I've also tried without them ticked). I then added the "HelloWorldAgent.java" that comes in the examples to the src. I set up the run configurations as:

When I run using this configuration the JADE guy does start but it does not find the "HelloWorldAgent". The output is:

The key problem clearly being:

SEVERE: Cannot create agent testAgent: Class HelloWorldAgent for agent ( agent-identifier :name testAgent@192.168.1.66:1099/JADE ) not found [nested java.lang.ClassNotFoundException: HelloWorldAgent]

I've tried using eclipse but I get the same problem, I also tried using a earlier version of JADE but again, no luck. Any help would be much appreciated.

Many Thanks

Solution

  • It seems that the location I put the "jade.jar" and "commons-codec-1.3.jar" was the problem (I originally put them in /Library/Java/Extensions (in OSX lion)). I tried removing them, putting them somewhere else and tried again and now it works. Not entirely sure why mind!
