Hi all,

I was reading the JPA specification and there is something I can't understand ( examples ).
We have a lot of example of how to point to a jar file containing entities.

Example 5:
WEB-INF/lib/warEntities.jar WEB-INF/classes/META-INF/persistence.xml
persistence.xml contains: <jar-file>lib/warEntities.jar</jar-file>

I think I am wrong but persistence.xml should contain : <jar-file>../lib/warEntities.jar</jar-file> ?

Could you please give me a piece of advice on that purpose ?

In the same way if we look at :

Example 7:
WEB-INF/lib/warPUnit.jar (with META-INF/persistence.xml )
persistence.xml contains: <jar-file>../../../lib/earEntities.jar</jar-file>

I think it should contain <jar-file>../../lib/earEntities.jar</jar-file>
thank you for your feed back, I'll check the links you gave

i'm currently studying Pro JPA 2 book and by now, I'm on the Criteria API chapter ... And OMG this way of writing query is just terribly complicated and ... definitively unreadable !!
But we have to study it (a shame because I perfectly know that I will never use such a thing ! I can't even imagine someone who discover that kind of query in a real world project with thousand of queries)

Still we have to know all of it ...

I try, when reading, to write down every methods and inheritance stuffs but I can't make it clear

Does anyone know where to find a class diagram with all important Interfaces and methods ? a kind of sum up diagram ?

And I am curious about this. Does anyone ever met the use of Criteria API on a real project ? What's the gain ?

thanks a lot
firstly, thanks for your answers

Hello all,

In few month I will be on Melbourne and before I get there, I want to prepare myself as well as I can.
It is obvious that french resume and australian one are different, the point is that I cannot find good example of australian Java developer resume.

Have you some good website on the purpose ? Or better : reals resumes I could work with to create mine ?

I've doubts about question 6 of Marcus green first mock exam

first of my doubts, is that not a problem to have a <role-name>manager</role-name> out of <auth-constraint> </auth-constraint> ?

Then I was sure that when you have no <auth-constraint> nor <role-name>, all user authenticated or not could access resources.
But in answer it says :

Although the first auth-constraint is empty, implying no one will have access to the resource, this is cancelled out by the second auth-constraint that will allow anyone to access the resource.

Last but not least please tell me how does it work, if for the same URL you have multiple constraint, which constraint will be used ? the less restrictive ?


In Charles Lyon's book there is nothing about thread safety on context, session, request attributes.
Does this subject is still required for the exam ?


I read too quicly the question, sorry :'(

I think F should be correct, you can specify timeout in DD like that :


No way to find it ...
if you find a way, please tell us.
