What specifically are you trying to do or having trouble with? There's no (major) difference between Oracle 11g and any other DB in this regard (although I'd steer clear of Struts 1's <datasource> element or whatever that is; it's deprecated, and there are better ways to deal with it).
I am facing trouble in making connection of srtuts1 with hibernate and oracle 11g which is a back end. Do i need spring also for connection establishment and successful CRUD operations of hibernate .How to display the data in webpage from the database ,for this display tag is better or datagrid from struts improve technologies is better?
Please help me out in these regard!
You can't have everything. Where would you put it?
