Hi,
I ned to do a database connection pooling in my project.
i need to develop the project for web environment and also as an application.
my first questuion is if i use a connection pool where will i get the connection in a sevlet in the init() method or the servic() method.
is it advicable to have it in the service method?
Will i get ready code for connection pooling and from where?
What are the issues i need to take care when developing the connection pool

You should put it in the service() method in order to effectively use connection pool.
Check the servlet forum on Javaranch, you would find more info there.

you can probably check this out..sample connection pool code. http://www.webdevelopersjournal.com/columns/connection_pool.html
I w'd probably put it in the init() method.
I don't know why it s'd be initialised in the service().
init() w'd be called when u load the servlet through the web server. So i guess all initialisation can go there?
cheers,
karthik.
 
It is sorta covered in the JavaRanch Style Guide.
