My doubt is
1) I do a getConnection two times but should I close two times using returnConnection or one returnConnection is enough.
2) I read about a concept called "Weak reference".Does this example point to that.Any more simplified explanation availabe
for the concept somewhere.
3) As of now , I have used two return connection (i have uncommented the code in the finally to avoid problems)but I feel its redundant.Please correct me if am wrong.
