15:59 sjmaple hey Arslan
16:01 Omkar_India joined #virtualJUG
16:01 sjmaple this is the place to ask questions folks - please ask everything you want about Java EE in general or as part of the first 6 chapters in the book
16:03 redman joined #virtualJUG
16:03 Ez joined #virtualJUG
16:04 sievemaker appreciate standards, love/ need flexibility
16:05 gauravbrillls joined #virtualJUG
16:06 sjmaple can you expand, sievemaker?
16:08 sievemaker sometimes standarization stops developing proces, like in JavaSE, many people would expect features from Scala world, what happens in projects like... javaslang, but java adopts slowly. what is good and wrong in the same time. I would say... ;) Java is like Catholic church... stable, evolving slowly
16:08 justadev23 joined #virtualJUG
16:10 sjmaple yeh, I agree - it's what enterprises love about Java, right :)
16:11 Victor joined #virtualJUG
16:12 YoYo joined #virtualJUG
16:12 Sab joined #virtualJUG
16:14 sievemaker I think that many projects use not exactly something what I would call legacy databases. even if you start the project from scratch often database is shared, and versioned separately. Have you ever work in the project when database is generated based on JPA Entities?
16:14 YoYo remember the primary objective of specifications is to allow developers to have choice among implementations
16:14 stevenziggiz joined #virtualJUG
16:17 sjmaple questions questions questions please people! :)
16:17 sievemaker Is the performance of CriteriaQuery and JPQL similar/ the same?
16:18 sievemaker So your advice is rather not to use Criteria Queries? ;)
16:19 Sab Hi, this is a question about JPA :
16:19 Sab JPA is a specification of JavaEE.
16:19 Sab EclipseLink and Hibernate are 2 implementations of JPA.
16:19 Sab Does that mean that my Java code will be exactly the same if I use EclipseLink or Hibernate (maybe except some configuration files as persistence.xml) ?
16:19 Sab Is it the same for all the specifications of Java EE?
16:20 sjmaple thanks! great questions! keep them coming! :D
16:21 YoYo joined #virtualJUG

16:25 gauravbrillls joined #virtualJUG
16:26 YoYo joined #virtualJUG
16:26 sievemaker What do you think about Querydsl vs CriteriaAPI would it maybe one day be a part of JPA Spec, maybe it will replace CriteriaAPI?!
16:26 Pranav How to choose inheritance strategy?
16:26 lalwanis joined #virtualJUG
16:27 sievemaker :D
16:28 sjmaple moving to CDI now, for time reasons
16:28 sjmaple sorry sievemaker, Pranav!
16:28 sievemaker :)
16:28 Pranav np
16:28 sjmaple CDI questions now welcome though :D
16:29 Jigar Can you explain @IdClass and @Embeedable/@EmbeededId difference pros/corns, always puzzeld by it?
16:29 gauravbrillls1 joined #virtualJUG
16:29 sievemaker Ilike when my container does it ;)
16:29 sievemaker my container is always so excited
16:30 gauravbrillls1 how abt mysema querydsl instead of criteria
16:30 sjmaple wow, that was quite an expressive demo
16:34 gauravbrillls1 some of these asynch and schdules have been incorporated by spring I guess
16:36 sievemaker EJB is actually in 7th chapter ;)
16:37 Pranav Spring doesnt follow Java EE spec
16:38 _ollie @Pranav: That's more wrong than right though :).
16:38 gauravbrillls1 yup but in parts some
16:38 YoYo joined #virtualJUG
16:38 gauravbrillls1 like jpa .. some annotations and stuff
16:38 gauravbrillls1 also cdi seems spring in spirit
16:38 gauravbrillls1 though not used cdi often
16:38 _ollie CDI is basically a broken version of the Spring DI container ;)
16:39 sievemaker Spring is just an incubator for JEE concepts ;)
16:39 gauravbrillls1 +1 ollie
16:39 lalwanis discussion
16:40 lalwanis right _ollie
16:41 gauravbrillls1 excellent explanaton of embeddedid and idclass awsome
16:41 gauravbrillls1 think will read the book .. have it on my safari acct
16:42 sievemaker I am not sure if using validation as an example for @PrePersist was a good choice as it is a field for bean validation.
16:42 sjmaple gauravbrillls1: you can get a discount with the vJUG code given in the meetup event page
16:42 toplars joined #virtualJUG
16:43 lalwanis :)
16:43 sievemaker :)
16:43 sjmaple You can get the book with 25% discount from http://www.springer.com/us/book/9781430246268 by using the discount code JEE116.
16:43 sjmaple 7 mins to go
16:44 sjmaple any final questions
16:44 Pranav use of @decorator
16:44 gauravbrillls1 thank @sjmaple though have it in my safari subscription but will reco to folks
16:44 sjmaple oh, I see :)
16:44 sjmaple Pranav: can you expand pls
16:45 sievemaker i bought at amazon/ kindle version
16:45 Pranav @decorator -is it related to decorator design pattern
16:45 lalwanis is CDI with no xml?
16:49 lalwanis :)
16:49 YoYo what comments can be shared regarding the merits of JavaEE web profile and projects like Apache TomEE
16:49 lalwanis Thanks guys
16:50 sievemaker great session, great book
16:50 sievemaker thx
16:51 gauravbrillls1 great discussion ..
16:51 Jigar As spring has lot of libraries like loading system properties etc, with CDI should we hand code or there are some options which dose such thing of-the-shelf. Any recommened CDI frameworks, one i know is deltaspike any more suggestions ?
16:51 gauravbrillls1 thanks all
