Subject Re: POOL - Question about different time out for borrow and add object
Date Wed, 29 Apr 2015 19:55:57 GMT
Hi Phil..

Thanks for response. i agree that add object is not problem as i am pre
filling the pool and i can wait until the pool gets filled. But the real
prob is with borrow object where i have to call the external system if
there are no idle objects and the pool didn't reach the max size.

In this case the pool will try to create new object by using factory make
object method. The same method which add object also uses to add object to
pool. I this case the borrow objeect call will get blocked until new
connection is provided by external system (This could be some time more
than 5 mins)

The factory instance of the pool at this particular point has no
information of whether the call has happened from borrow object or add
object of pool to handle the time out based on add or borrow...This is
where iam stuck ...

can you help me how to implement it ..
