FYI, this is what's causing configurationAsXmlString to fail:

That attribute doesn't seem to be working for me. When I try to access it in jconsole, I get this in the server log:

10:56:53,338 WARN  [org.infinispan.jmx.ResourceDMBean] (RMI TCP Connection(2)-127.0.0.1) ISPN000036: Did not find attribute configurationAsXmlString

If I try to access it programmatically, through the MBeanServer, I get this in the server log:

10:49:27,598 ERROR [stderr] (http-/127.0.0.1:8180-1) javax.management.AttributeNotFoundException: Unknown attribute 'configurationAsXmlString'. Known attributes names are: [cacheName, cacheStatus, configurationAsXmlString]

which seems strange, since it's reported among the "known attribute names". Nothing obvious jumps out at me from looking at the code for ResourceDMBean.

Did you try: Cache.ConfigurationAsXmlString jmx property?
