Getting connection toa database in a thread

Question

Hi
I need guidance on how to get connection to a database inside a thread.Let me explain in detail.
I am developing a chat application. As normal my chat server assigns each user an instance of a chathandler class which runs as a thread.The problem is that i need to connect to database inside this thread to implement some group wise logic in the broadcast method of chathandler thread.
Now for this can i create a connection object each time in the thread or can i use a common connection object ? If i go for the second method will it cause any concurrency issue ?
Thanks in advance

Hi
I need guidance on how to get connection to a
database inside a thread.What other way is there? You always get access to a database inside a thread.
Let me explain in detail.
I am developing a chat application. As normal my
chat server assigns each user an instance of a
chathandler class which runs as a thread.The
problem is that i need to connect to database inside
this thread to implement some group wise logic in
the broadcast method of chathandler thread. No, database connections are for persistence. Group wise logic belongs somewhere else.
Now for this can i create a connection object each
time in the thread Yes, for each database access. Create it, use it, close it. Use a connection pool to amortize the cost of opening a connection.
or can i use a common connection object ? If you're foolish you can. How scalable is an app with one connection?
If i go for the second method will it cause
any concurrency issue ?You'll have isolation and concurrency issues to worry about in any case.
