Hi Everyone, After the installation and the executon of rabbitMQ I successfully launch echo application from XBaya gui.
I've a couple of more questions: - Where I can find the result/output of the experiment? (The monitoring panel gives me only the STATUS) - Navigating the code I found some reference that makes me a little confused. Keeping the "echo application" as example, we declare an Application Input which I suppose to represent the "string" that we want to "echo", and an Application Output which I expect to be the "output" of the echo command (thus, is exactly the same string that we provide as input). If my assumptions are correct, what is the purpose of the "applicationArgument" and "StandardInput" member into InputDataObjectType class? applicationArgument is to be used to represent complex structures? How can I use them?

Thanks, Shameera.

I presume I have to install it separately...

To configure rabbitMQ with airavata, follow the below steps. Start RabbitMQ server Stop the running airavata serverIn airavata-server.properties, 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. Thanks..Chathuri On Tue, Nov 4, 2014 at 10:05 AM, SmashRod Alfredo <[email protected]> wrote: 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 localhost?
