NoClassDefFoundError HierarchicalStreamDriver when using STOMP

[braiam]

Hello.

Well, even with my long experience working with ESBs (an experience that spans for the last four hours working with Fuse ESB ) I am not able to establish a communication between Fuse ESB and the PHP STOMP client (http://stomp.fusesource.org/)

Fuse ESB starts correctly, and I'm able to use the web console. I've tried some xml examples of publishing to the ActiveMQ and everything works perfectly. But now I'm trying to publish a message using the PHP Stomp client

$con = new Stomp("tcp://localhost:61613");

$con->connect();

$con->send("/queue/test", "test");

$con->disconnect();

The request times out and prints this in the browser

Fatal error

and this gets logged into the karaf console

What action should I perform to let Fuse ESB know where HierarchicalStreamDriver is? Should I install any feature? Should I run any maven command?

Thank you!

Hi

You may consider to install the feature of camel-xstream which has the dependency of the xstream bundle.

Worked perfectly!

Thanks njiang!

The xstream support in AMQ is from the activemq-optional. Fuse ESB should IMHO have a feature to install that. So I have logged a ticket
