Hi Erik
Yes, you can certainly configure several settings.
I do realize that our documentation on this is sparse.
I will take that as a to do to address. Perhaps we should expose a JMX
MBean that allows users to view through JConsole or a management UI
specifics about Shoal communication through Jxta and the configuration
settings.
In the least, the multicast address and port can be specified.
Look in the ServiceProviderConfigurationKeys.java
<
https://shoal.dev.java.net/source/browse/shoal/gms/src/java/com/sun/enterprise/ee/cms/core/ServiceProviderConfigurationKeys.java?rev=1.7&view=markup>
for all properties that can be set.
The Application Server demo code
<
http://b.amiot.free.fr/index.php?entry=entry080114-055255> that is part
of shoal's tests directory shows how these configurations can be specified.
Hope this helps while we get these configs better documented.
Cheers
Shreedhar
