Hello,

I have a query in usage of 2nd Level Caching mechanism(provider : Eh-Cache) for hibernate 3.0.

I am using JPA 2.0 interface to connect to hibernate 3.0 and implement back end functionality.

My Query is that how can I cache Data Base tables in JPA 2.0 using Annotations..

Eg: For table A.. We configure in the A.hbm.xml file the following code of line
<cache usage=”read-only” /> .. to tell Hibernate to Cache the data of this Respective Table.


In JPA 2.0 , How can i Tell Hibernate using the JPA annotations/interfaces to Cache a database Table(Entities of the table).


I am aware of the Annotation..
@Cache.. in hibernate
to tell it to cache a table.. How can we acheive the same thing in JPA 2.0

Will this Annotation.. @Cachable... be usefull in JPA 2.0 to cache(2nd Level) a particular table Data?

Thanks And Regards.


Kindly let me know if my above query is unclear if if more information is required from my part.

I was able to configure 2nd level Caching using Hibernate Annotations in my entity pojo java files.

My Requirement was :

My database tables are only ready only tables for reference purpose for teh first time when the user logs in . I don't want them to be changed by any user while he is updating the persistent entity objects through the provided user interfaces...

That is, the data is fetched and stored into entity classes only for the 1st time by hitting the database ,when the user logs in for the first time..
After that, there after, what ever changes the user does, to that data, it should be only updated in the cache.. and not in the database table......

Is it possible to achieve through Hibernate or any other ORM tool??????

Also , Is it possible to use any Cache Provider API's to obtain the above desired result.??????


KINDLY GUIDE.!!
THANKS.!!!
