I am preparing for OCEJWCD 6 from five months.Oracle introduced new Version java ee7
So skip the current version JavaEE6 and paln for preparing JavaEE7.
I am just worrying that Oracle will introduce a new certification exam like OCEJWCD 7.
so, what should i prepare and when it will happen?
For the Architect exam (OCMJEA formerly SCEA) the upgrade from JEE5 to JEE6 happened somewhere around late 2013 - early 2014, but Oracle ran beta testing of new exam for a few month before upgrade.
And even after the upgrade, when new JEE6 Architect exam became available for general public, old exam (verified against JEE5) has not been retired and is still available (although I opted in taking a new version).
So since no beta test for upgraded OCPJWCD is available, you have nothing to worry about.
