hard friday
ds-tesst.jsp passed the test. Configure cache and JPA API
Work fine. Configured ehcache for hibernate NOT for Spring so cannot use @Cacheable jee annotation. Only work through spring. Don't know if a ehcache hooks BitronixTransactionManager. TODO: test it

Hint: skip it. Set up a web-app then play with @Cacheable and @Transactional
