Hi all,
I made a Personalization project which a user select his content category
and then he or she chose his selections from this content(add or delete).
I made a DB Layer classes to interact with DB and i made add and delete
methods like
synchronized public boolean deleteHoroscope(String horoscopeCode){
...
}
i also do my servlets as
implements SingleThreadModel
It was okay without concurrecy
But users are losing their personalized.
When i trace the DB SQLs which includes DELETE statement i can`t see any
abnormal statement?
What could be reason?
What should i do?
Do you know resource that i should read?
Thanks all in advance.
