Hi, I get the same warning, but due to jboss.server.data.dir pointing to a custom directory. jbossjta-properties.xml has com.arjuna.ats.arjuna.xa.nodeIdentifier specified. The default layout jboss - server -- default ---- data works, but my layout: root - data - jboss -- configname results in Name of XA node not defined. Already tried to add root/data and root/data/tx-object-store to the CP, which did not help. Could you exlain what was meant with "jbossts etc dir"?
