This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Firstly - I'm a newbie to Java so this post may not be in the correct place.
I'm need to move a Java Servlet from using a MySQL backend to Oracle. No major problems there - although I'm searching this servlet and I can't for the of me find the current connection string in order to change it.
I've used the IDE search functionality and a text based searcher - I know the name of the current connection.
One thing that is unfamilar to me is it appears to be using persistence (e.g. annotations like @PersistenceContext, @Entity and @Table(name="dbtable")) - does this entity stuff store the db connection string hidden away somewhere? Is there a good guide out on the internet for this terminology where I can play around and follow some tutorials?
Once again, apologises if this is in the wrong place or is lacking information - please let me know and I'll be happy to amend, and give further details...
