Discussion:

2014-06-03 14:45:32 UTC

Hi, i started using Jade recently, and i have some problem with the
JadeGateway configuration.

1) I start jade RMA by terminal using java jade.Boot -gui
(in the CLASSPATH i've added jade.jar and mywebapp.jar that include
AgenteGateway class and User class)

2) to running the web app i use eclipse and Tomcat (with jade.jar)

...also in localhost:

3) if i run Tomcat Server without mywebapp.jar the error is this:

(during jadeGateway.execute("agents.AgenteGateway", null))

Hi Gianvito,

I am making a project with servlets, Tomcat and Eclipse too. In the
classpath (run configurations) of my project I included myproject.jar,
jade.jar and the commons-codec-1.3.jar. And it is important to include this
when you run the agent, like the following:

java -cp
lib\jade.jar;lib\commons-codec\commons-codec-1.3.jar;lib\MyProject.jar
jade.Boot -gui -container -agents myagent:agent.AgentExample

If you have problems you can write me and I will be glad to help you.

Hi Gianvito,

I don?t run the Gateway agent by the console. I start it in the servlet.
You can find an example in the folder doc/tutorials/JadeGateway.pdf of
jade.

I run the gateway like this:

*public* *void* init() *throws* ServletException {

JadeGateway.*init*("agentpackage.myAgent",*null*);

}

So you can use it when you write:

*try* {

JadeGateway.*execute*(myMessage);

} *catch*(Exception e) {

System.*out*.println(e);

}

Kind regards.
