Eclipse Juno cannot make new project after update

Question

I'm using Ubuntu 12.04, and to install Eclipse Juno I downloaded it from the official site (I don't use apt-get nor software center)

After updating it from help > check for updates menu, my Eclipse cannot make new project. When I hover File > New, there isn't any menu to select (as the usual Java Project, C++ Project etc.), only an unselectable text like this:

< No Applicable Items >

Anyone know what causes this?

nitind's answer above helped solve my problem. I was using eclipse java ide juno on windows and i could not see any items under File -> New or under Window -> Show View. I noticed eclipse had defaulted to using the Java-EE perspective. Following nitind's suggestion I changed it to the Java perspective and can now see all the menu items. thank you!
