There is no provision for notification on new transactions, and it might be difficult to separate those for events of interest in your app and those of for instance other apps. Also, although xids are in fact currently created using a incremented number, this is really a hidden detail, and before jboss 4 these numbers repeat on jboss restart. You could probably most easily make an XidFactory that would notify you on new tx. > > I am quite happy to use oracle triggers and oracle > variables in global packages etc. The tricky bit is > how to pass the extra information that I need in the > master audit table and how to link the small audit > tables with the foreign key to the master one. Indeed. That's why I think using cmp2 is worth a look. david jencks > > I have read here people tried to inherit some jboss > interceptors to achieve this. Can anyone share a > sample code?
