Troubleshooting
The org.jboss.as.jpa logging can be enabled to get the following information:
INFO - when persistence.xml has been parsed, starting of persistence unit service (per deployed persistence.xml), stopping of persistence unit service
DEBUG - informs about entity managers being injected, creating/reusing transaction scoped entity manager for active transaction
TRACE - shows how long each entity manager operation took in milliseconds, application searches for a persistence unit, parsing of persistence.xml

is managed by the underlying persistence provider.
-
New (transient):
-
an entity is new if it has just been instantiated using the new operator, and it is not associated with a persistence context. It has no persistent representation in the database and no identifier value has been assigned.
-
Managed (persistent):
-
a managed entity instance is an instance with a persistent identity that is currently associated with a persistence context.
-
Detached:
-
the entity instance is an instance with a persistent identity that is no longer associated with a persistence context, usually because the persistence context was closed or the instance was evicted from the context.
-
Removed:
-
a removed entity instance is an instance with a persistent identity, associated with a persistence context, but scheduled for removal from the database.

Considerations When Exporting CSV
-
The biggest differences are in how these three characters are handled. Embedded double quotes in fields. An escape character is sometimes used to introduce a double quote, or in place of it. Embedded line-feeds in fields. This one is also escaped sometimes. Often like in C ("\n") Embedded commas in fields. Again, an escape character is sometimes used in place of the comma

stateless EJB 3.1 bean as boundary (Facade)

@Inject

-
@Inject
-
CDI managed beans. The @EJB annotation is removed and @Inject is used instead
-
Annotating the boundary (Cart) with the @Named annotation makes the Cart immediately visible for expression language (EL) expressions in JSP and JSF
-
@Named annotation takes the simple name of the annotated class, puts the first character in lowercase, and exposes it directly to the JSF pages (or JSP). The Cart bean can be accessed directly, without any backed or managed beans, by the JSF pages: <h:commandButton value="Check out!" action="#{cart.checkout}" />
-
If there is a need for abstraction, the class can be turned into an interface (or abstract class)
-
local implementation (with CDI events

@Inject Event<String> event;

-
event can be received by any managed bean and also by EJB beans
-
provide a method with a single @Observes annotated parameter
-
@Observes String event
-
there is no real event, just the payload:
-
The during attribute in the @Observes annotation allows you to select in which transactional phase the event gets delivered. The default setting is IN_PROGRESS, which causes an immediate event delivery regardless of the transaction outcome. The AFTER_SUCCESS configuration causes the delivery to occur only after successful transaction completion
-
Although CDI events work only inside a single process (in the default case, CDI is extensible), they are perfectly suitable for decoupling packages from modules
-
The method checkout() starts a transaction that gets "reused" by the OrderSystem and CustomerNotification session beans
-
ordering.placeOrder(); notifier.sendNotification();
-
-
EJB beans cannot be directly exposed to JSF or JSP without a little help from CDI

Not able to set global mime-mapping

mime-mapping is complex field and not resource. that is why it has its own operation handlers add-mime/remove-mime to handle its value. what are you trying to achive can be done by command:

/subsystem=web/configuration=container:add-mime(name=manifest,value="text/cache-manifest")
- ...1 more annotation...

Just bit of a warning when using this, there was a bug in 7.1.1 when you added mime type that prevented server to start.so please use 7.1.2 or 7.2 nightly builds where this is fixed.

GDS/Tide project represents the Data Services part of GDS

-
strongly typed Hibernate/JPA detached objects
- ...5 more annotations...
-
All managed entity instances are unique in a Tide context
-
Tide keeps the classic three layers web architecture, when LCDS removes the service layer, and is some kind of remote JPA provider for Flex applications
-
Tide approach is to minimize the amount of code needed to make things work between the client and the server
-
principles are very similar to the ones of JBoss Seam, which is the main reason why the first integration of Tide has been done with this framework. Integrations with Spring, EJB 3 and CDI are also available

-
to reproduce the same awful patterns
-
please not this Dao/Template mess
-
Because, of course, there are no other well-known patterns for dealing with boiler-plate cleanup code and connection leaks.
-
This is exactly the kind of
-
brain-damage that Spring does to people!
-
-
It gives people a
-
half-assed solution
-
and somehow shuts down their brains so they
-
stop asking themselves how this solution could be improved upon
-
It's a very impressive magic trick, and I wish I knew how to do it myself. But then, I'm just not like that. I'm always trying to poke holes in things - whether they were Invented Here or Not.
-
but that might be too high-level for your taste. Their are other, less-abstract options.
-
exception handling, this is one area where Spring does a good job: "The Spring Framework's handling of SQLException is one of its most useful features in terms of enabling easier JDBC development and maintenance. The Spring Framework provides JDBC support that abstracts SQLException and provides a DAO-friendly, unchecked exception hierarchy."
-
Utter nonsense and dishonest false advertising
-
Automatic connection closing (and other boiler-plate code) is obviously a hard requirement to be handled by the fwk.
-
Pffffff. It's a trivial requirement which I can solve in my framework with two lines of code in a @Disposes method. Did you see any connection handling in the code above?
-
I mean, seriously guys. The Spring stuff is trivial and not even very elegant. I guess it's easier for me to see that, since I spent half my career thinking about data access and designing data access APIs. But even so...
-
I don't understand. You hate the ability to write typesafw SQL that much?
-
Gavin King
-
Methods with long argument lists are a code smell.
-
It's something Spring copied from Hibernate 1.x, back in the days before varargs
-
It's something we removed in Hibernate2 and JPA.
-
there are a bunch of people
-
who don't want to use JPA.
-
They don't understand, or see the value of, using managed objects to represent their persistent data.
-
Um. Why? Why would that be a bad thing? I imagine that any app with 1000 queries has tens of thousands of classes already. What's the problem? Why is defining a class worse than writing a method?
-
Are you working from some totally bizarre metric where you measure code quality by number of classes?
