I don't know if Websphere does it's own connection pooling. You may want to look into it though. Since it means that several hits to you servlet will share the same connection.

For a DB connection pool initialization the best means would be as
follows in decreasing order of preferance
1. Context Initialization
2. init() method
3. initialization on the receiving the first request.

Use a DataSource. IBM has a good example of setting this up at
Advanced application assembly and deployment tutorial
Once it's configured for your server, any example code for using a Connection from a DataSource will work.
I Hope This Helps
