Hi, Can anybody clear my doubt?? When we are using JDBC service of a J2EE server(e.g Connection pooling in Weblogic server) what type of driver are we really working with. Is it Type 3 because we are using a server to select the driver or is it a Type 4 because we are declaring the driver in the URL field(while configuring the serever to implement the conection pooling). OR is it like we are using the combination of Type3 and Type4?? I hope my question is clear.
