JADE cannot find agent

Question

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:

• Main class: jade.Boot
• program arguments: -gui testAgent:HelloWorldAgent
• Use class path of module: jadeCW (my projects name)

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 [email protected]: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

Answer 1

You need to pass the fully qualified name of the class when you start it. On my old version of JADE, the HelloWorldAgent is in the examples.hello package. Thus you should specify the program arguments: -gui testAgent:examples.hello.HelloWorldAgent.

Answer 2

Just add the Package Name before the class Name

-gui testAgent:packageName.HelloWorldAgent

Answer 3

You need to add:

-gui nameAgent:packageName.className
