This following error message can occurs in different use case:
{code}
sample-0 2013/04/18 09:34:07,473 GMT+0200 SEVERE [Petals.Communication.RMIConnector] : Failed to start JMX RMI connector service
java.io.IOException: Cannot bind to URL [rmi://localhost:7700/jmxRmiConnector]
{code}
The known use cases for which the problem can occurs are:
* a topology containing only one node,
* a topology containing several nodes
h2. Topology with only one node
*Operating system:* All
*Symptoms:*
# You have configured your topology with only one Petals node declared as master,
# You try to start your Petals node for the first time and you get the following error message:

*Solutions/Explanations:*
The name of the machine on which Petals ESB runs cannot be correctly determined. The main error source is an invalid entry in your DNS configuration or in your file {{etc/hosts}}. The name of your machine is not associated to the correct IP address. Setting the right IP address to your machine name should solve the problem.
h2. Topology with several nodes
*Operating system:* All
*Symptoms:*
# You have configured your topology with several Petals nodes declared as slave,
# Your Petals node declared as master starts correctly,
# You try to start your Petals slave for the first time with this distributed topology,
# You get the following error message:

*Solutions/Explanations:*
You have missed to configure the Petals container name in your $PETALS_HOME/conf/server.properties. The default Petals container name '0' is used and it is associated to Petals ESB master node that is configured in your topology with a different IP address that is not local to your Petals slave node.
