What is the difference between Eclipse IDE for Java(EE) Developers and Eclipse Juno .
The concepts are orthogonal.
"Juno" is just the fantasy name for the IDE version 4.2. Different (succesive) releases are called by a number (3.7, 4.2, 4.3 ...) and also by a codename:
Eclipse 3.7 = Indigo
Eclipse 4.2 = Juno
Eclipse 4.3 = Kepler
Eclipse 4.4 = Luna
Eclipse 4.5 = Mars
Each release, in turn, can be downloaded in several packaged variants, which differ only in which plugins (functionality) are included ("Eclipse IDE for Java EE Developers", "Eclipse for RCP and RAP Developers", etc).
There are usually no relevant issues in migrating from one version to another, in general you should try with the last version.

Eclipse IDE has more versions like
Eclipse 3.7 = Indigo
Eclipse 4.2 = Juno
Eclipse 4.3 = Kepler
Eclipse 4.4 = Luna
Eclipse 4.5 = Mars
Eclipse 4.6 = Neon (planned)
so Juno is not different IDE it is a version of EclipseIDE see wiki eclipse
No, but you can update classic version for it to be same as Eclipse for J2EE version.
The best way (which I know) is:
1.In Eclipse go Help -> Install new Software...
2.Press Add...
3.In address enter http://download.eclipse.org/releases/indigo/ and name - whatever you like.
4.Install JavaEE Developer Tools (under "Web, XML, JavaEE, and OSGi Enterprise Tools")
5(Optional, but very useful).Install Marketplace Client (General Purpose Tools -> Marketplace Client).
That's about it, after this you should have the same environment as client you would download from Eclipse.org.
Eclipse comes with differents configurations but there is always the same "eclipse" as core application. They are the same Eclipse with differents collections of plugins that you can install, remove and update trough the package manager integrated in Eclipse itself. That's why you can't find the Eclipse you want with an apt package manager.
You also do not need to install eclipse or java ( the .bin version from the Oracle website ), they can be unpacked in a local folder, for example you can unpack this two in your home folder and then add the -vm option to the eclipse.ini or launch eclipse with the -vm option, example:
\local\path\to\eclipse -vm \local\path\to\the\java\machine\used_by_eclipse
TLDR: If I want to do J2EE development AND a bunch of other Java stuff, can I just install Eclipse IDE for Java EE Developers.
It seems like Ecilpse IDE for Java Developers a super set of Eclipse IDE for Java EE Developers. Can I just uninstall the latter and install the former and everything will be cool?
I prefer asking questions here because unlike Stack Exchange or the other services I'm not afraid of getting stabbed.
Install Eclipse IDE for Java EE Developers. This flavour of Eclipse is bundled with everything to start building Java EE applications. Download the Latest Release (Eclipse Helios) here.
I think Eclipse has different flavors, so pick the one that works for you. Java EE includes the servlet/JSP piece you need. I'd go with that.
I installed Eclipse for Java Developer and now I want to switch to Eclipse for Java EE Developers. One way that I see is by uninstalling and reinstalling the Eclipse IDE and selecting Eclipse for Enterprise Java Developers during installation.
Is there any other way to do so? Also, I found here to not upgrade by adding the missing plugins.
