Test application running error

ttbachyinsda commented 6 years ago

Hi, I am trying to test some functions of athena, and I have made a successful compilation in ubuntu 14.04 64bit and oracle JDK 8. But the command ./athena-run-realtime throws an exception like this: SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/home/ttbachyinsda/athena-1.6/athena-tester/target/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/ttbachyinsda/athena-1.6/athena-tester/target/lib/slf4j-simple-1.7.6.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/ttbachyinsda/athena-1.6/athena-tester/target/lib/slf4j-jdk14-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

I think this exception may due to multiple SLF4J bindings, but I have not found the reason. Could you help me to find that?

Hello, According to the debugging messages, I think you miss to run a controller instance. The debugging message (Exception in thread "main" java.lang.NullPointerException at athena.util.ControllerConnector.sendToController(ControllerConnector.java:109) at ) indicates that there is no controller to register the event handler. Before starting to the athena application, please run the controller to delivery Athena features in run-time.

If you want to run Athena application in a batch manner, you don`t need to register an event handler.

Thanks.

I have carefully checked my "make install" step, and I'm sure now some athena modules are running in ONOS, but the error still exists. I guess there might be some connection errors. But I run ONOS in one bash and test program in another bash, there should be no connection problem. So could you please show me the environment and tools that you used to run athena, maybe I used a problematic environment. Thanks! Below are the console output of onos:

onos> app activate org.onosproject.athenaproxy onos> app activate org.onosproject.framework onos> feature:list Name | Version | Installed | Repository | Description

Sorry for the late. I need to update the notification settings. Here is the answer what I reply by an email.

Hello FangZe, The exception means “the Athena application fails to connect the Athena framework instance running on the controller”. The problem is the current version of Athena does not have graceful connections. So, An order of executions is crucial to avoid exceptions. So, Please do followings to fix the problem;

1) First of all, turn of an Athena framework instance on ONOS CLI (app activate org.onosproject.framework) 2) Then, run the proxy instance (app activate org.onosproject.athenaproxy) 3) Finally, execute the Athena application instance.

That would be working.

Sincerely,

Seunghyeon.
