Multi-thread access to single EM's entities

If my entity classes have synchronized getters and setters, is it reliable for multiple threads to access a single EM's managed entities, as long as only the thread that created the EM interacts directly with it?  I've tested this and it seems to work... but I know better than to depend on the observable behavior of multithreaded code. When I run this example and examine the database, the entity contains the value set by the second thread, as expected.   #1 2012-04-09 02:22 If my entity classes have synchronized getters and setters, is it reliable for multiple threads to access a singl ...

GlassFish 3.1.2.2/JBoss 7.1.1

Good day, We have few troubles with GlassFish on @remote. When we wants to get entity from remote interface, but in the result we have null in all entity fields. As I see there is a GlassFish problem (http://www.java.net/forum/topic/glassfish/glassfish/cant-return-entity-ejbs-remote-ejb). May be you have some ideas?  When we just try JBoss 7.1.1 nothing works at all.

Recommendation - concurrent access multiple class v

Hi! I've just started to architect a new system, stateless JSON API, which is expected to have very high load and to require more servers for parallel deployments (same app across multiple servers). I am considering using ObjectDB, because of its advantages and easy usage, but I'm afraid that it might get corrupted because the manual says that we must not access ObjectDB with different versions of a class. Let's take the following scenario: ... Hi! I've just started to architect a new system, stateless JSON API, which is expected to ...

JVM crash when using IBM JDK 1.6.0

Hi! I've just discovered that I can't see the content of a database while it's in use. Is there any way in which I could do that? It's not nice at all to close the application, copy the db in another location, start the application then finally I could explore my data, but it will be just a copy of the data, not the live information. ...
