Hi Chathuri,
Thanks for your reply, just an information,
a RabbitMQ server instance is included in the airavata installation (like zookeeper), or it
is necessary to install it separately? I presume I have to install it separately...

Hi Alfredo, 
If you are using XBaya to run experiments, you need to have rabbitMQ server up and running
in order to xbaya monitoring to work. To configure rabbitMQ with airavata, follow the below
steps. Start RabbitMQ server Stop the running airavata serverIn,
change the property "publish.rabbitmq" to true (publish.rabbitmq=true)Start the airavata server
againRun echo experiment from xbaya againLet us know whether this fix your problem.

Hello everyone,
I've downloaded the latest version from git repository and compiled airavata without test
(I've tried to build it normally but gives me error testing app-catalog module). I managed
to start airavata-server which but gave me some issues about zookeeper and rabbitMQ.

However, the server seems to be running. After that I've tried to create my own experiment
for a simple Echo executed on localhost.
(I skip the calls to registerXSEDEHosts and rregisterGatewayResourceProfile and commented
all the reference to XSEDE resources elsewhere)

The echo application seems to be registered correctly, but when I try to create a simple workflow
through airavata-xbaya (that throws errors about RabbitMQ on start) using the registered echo
it gives me an exception Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

What did I miss? Is it necessary a particular configuration about GatewayResourceProfile for

Thanks to all,
