jpa 2.0 - JPA 2.0 Implementations comparison : Hibernate 3.5 vs EclipseLink 2 vs OpenJPA 2 -

-

What is your choice? Do you have any suggestions and experiences?

I am developing an application with Hibernate 3.5 and Spring 3.0

Professionals:

  • Good Document
  • Easy Configuration and
  • Some extensions of JPA
  • Some additional tools - Eclipse, Generating a Jabos tool for HBM 2 DLL, Static Metamodel etc. ...

Cons:

  • Bugs! (Sequence, collection, etc ..)
  • Many "it" hibernate has doubled a lot of iterations. There is a disturbance in legacy hibernate and JPA annotation.

What do you think I'm considering to switch to Eclipse Link?

Edit:

I have tried EclipseLink and have a very bad experience. It seems that Eclipse links require loadtime weaver and instead of ordinary JT or TOKamet environment OSGI likes to walk on the platform. I do not have time for all this configuration content so far.

Eclipse links run completely without weaver JT, tomatcats or OSGI platform equally well the way. Standard download is a simple eclipselink.jar. Have you accidentally downloaded OSGI bundles?

Weaver is not required but it will add some performance advantages and if you do not want to configure it to run in spring, you can use compile time () to static quadrature.

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
