Follow my code:

Company cc = em.find(Company.class, clientUser.getCompany().getId());
System.out.println(cc.getCompany_code());

HashMap findProperties = new HashMap();
findProperties.put(QueryHints.CACHE_RETRIEVE_MODE, CacheRetrieveMode.BYPASS);

Company oo = em.find(Company.class, clientUser.getCompany().getId(), findProperties);
System.out.println(oo.getCompany_code());

Just like the example "Used as EntityManager properties". here

But, there are nothing different between the two outputs.

What outputs? The System.out.println outputs? There won't be any difference there. Why would you expect there to be any difference?

I presume you actually mean that you are running eclipselink in some detailed logging level, and that you have observed that eclipselink is NOT re-running the query on the dbase. Is this what you mean?

I Believe there was a bug in the BYPASS not by-passing the find() cache check. I believe this was fix in the latest 2.2 development builds.

You can also use the query hints, "eclipselink.refresh"="true" or "eclipselink.maintain-cache"="false"
