Q: I am trying to connect my eclipse with oracle 11_g but it is asking for ojdbc14.jar I want to connect 11_g with my eclipse but it is continously asking for ojdbc14.jar

A: ojdbc14.jar and ojdbc12.jar are required files to connect database with java program which is present on Eclipse.
So you can download ojdbc14.jar from internet or it will present inside your oracle11g folder and add into eclipse.
steps to connect Oracle instance from Eclipse:
1)In Eclipse IDE and Select Database Perspective-Windows->Open Perspective->Other->Database Development).
2)Create Connection Profile, Chose Oracle
3)Choose JDBC Driver and specify its location
4)Specify connection detail e.g. localhost, port(8080), username and password ORACLE database
5)check Test Connection
