16:08 |

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 |

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 |

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 |

What do you think about Querydsl vs CriteriaAPI would it maybe one day be a part of JPA Spec, maybe it will replace CriteriaAPI?! |

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 |

EJB is actually in 7th chapter ;) |

Spring doesnt follow Java EE spec |

16:38 |

though not used cdi often |
16:38 |

CDI is basically a broken version of the Spring DI container ;) |
16:39 |

Spring is just an incubator for JEE concepts ;) |

I am not sure if using validation as an example for @PrePersist was a good choice as it is a field for bean validation. |

great discussion .. |

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 ? |
