Hi,
Thanks a lot for your answer.
Yes, I need that you describe your first proposition. For example, I want to
create only one business object who is charge to communicate whis a Database
and manage the differents concurrent requests from a lot of resource
methods.
Can you give me more details regarding your small example:
For class MySingletonResource, if the constructor is for example :
MySingletonRessource(File config), how (where) to instanciate it (new ...)
for my whole web appli ?
I suppose that MySingleton resource must be thread safe ?
The annotation @Pathname in some resource method will not be 'disturbed' by
the @Context annotation ?
If necessary, I can post a piece of code.
Thanks.
