you can specify connectioning pooling in weblogic.properties file I believe. WebLogic documentation is a good source for finding the information on how to setup pooling. since servlets are multithreaded, you cannot have a class variable representing the connection. in each method, you need to get the connection from the pool, do the work and return it back to the pool. I am sure weblogic has examples of working with database from the servlets since it is very common.
