Hi Everyone!
I'm learning JDBC , in that covering jdbc drivers ,i study about type-1,type-2,type-3 and type-4 and found interesting thing in type-3 driver and that created many issues ,
like while working with type-3 driver there is need webserver/application server because type-3 driver uses pooled connection object to perform any operation to communicate with database server.
so here i discussed about this concept to one of my colleague and he told that connection pooling concept is not there in any web server. i know the differences between web server and application server
but i'm not sure about connection pooling concept by this reason i have some doubts-

1-is it true that web server(any) does't have connection pooling concept?
2-as i know connection pool managed by some servers so can i use type-3 driver to develop 2 tier application ?

your answers is most valuable for me to clear my doubts so please do me reply..
looking forward for your replies and thanks for your valuable time to read this thread and for reply.
