POJO Cache supplies a pojocache-aop.xml that is required to be set via a system property: jboss.aop.path during compile- or load-time, or placed in the user's classpath. The file now consists of the interceptor stack specification, as well as annotations for POJO instrumentation. It is listed fully in the Appendix section. Note that the file should not normally need to be modified. Only an advanced use-case would require changes.
