Hi,
please read following thead:
http://old.nabble.com/Integrating-BTM-with-Hibernate-%2B-Infinispan-as-2L-cache%3A-BitronixSystemException-%3A-unknown-XAResource-ts26964799.html#a27010267
Apparently Infinispan is not fully XA compliant !
Overmore the thread is discouraging from running any Infinispan-with-XA code in production.
regards
G.D.
