When I click the Installation Details in eclipse,
I got this tab for Installed software
and a tab for Features
and a tab for plug-ins.
What are the relationships between eclipse software, eclipse features, and eclipse plugin as is shown in this window?
I guess Help -> Install New Software ... to install software, and software is comprised of a bunch of related plugins. Those two tabs are just the same contents (software names/plugin names) that is installed from Install New Software ... menu?
In his answer https://stackoverflow.com/a/12863077/260127, Bananeweizen says Eclipse "features" are the smallest installable pieces of Eclipse applications for users (e.g. the Java development toolkit). They consist of multiple plugins, where plugins are the smallest pieces that make sense from the developers point of view (e.g. org.eclipse.jdt.core, org.eclipse.jdt.ui, org.eclipse.jdt.somethingelse)., but to me it seems like eclipse feature is almost the same as eclipse software, and eclipse application is a set of eclipse software(feature) on top of eclipse platform.
"Installed software" is that subset of features, which you as a user actively choose to install in this Eclipse instance.
The features list on the other hand contains all features installed in this Eclipse instance. It includes all items from "installed software" and it contains the dependencies of the items from "installed software". Those are the features which you did not choose to install by yourself, but the Eclipse P2 update manager decided that, to be able to satisfy your installation request.
So again, an Eclipse installation process installs features, some of them on request of the user, some of them on request of the system to be able to install those from the user.
To make this all more complicated, Eclipse features are often referred to as "plugins" by Eclipse users, although that is not correct. So if you read about something like "installing the PHP plugin", that really refers to installing the PHP feature, which again consists of multiple plugins (but you don't see those as an Eclipse user, only as an Eclipse developer).
You can double click one of the features in that dialog to see the list of plugins it contains.
A plugin is that adds specific abilities to a larger software application.
Each plug-in
1)Contributes to 1 or more extension points(Means it can increase his property by just connecting it to any extension point)
2.)Small set of prog which generally require JRE and add some small feature to your Eclipse SDK..
While eclipse software is a set of plugins(Generally called RCP-Rich Client Platform )which provide a complete functionality to eclipse SDK.
Yep, software may consists of multiple plugins. "Installed" not only means that you have installed them via update site, but also this software were included in that package of eclipse.

I am using eclipse photon.
I am not getting servers view. I tried in Window -> show view -> other -> servers. But it's not coming.
Any solution for this?
Did you try resetting the perspective?
window -> Perspective -> Reset Perspective
After the reset, you may want to reconfigure all that is required, since it resets to the default perspective.
Photon is the name for a version, it has little bearing on what's actually installed as it represents a simultaneous release of 50+ projects that you can install in any combination you want. It sounds like you want the Web Tools Platform. Instructions for installing that are at https://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F .
If you do already have Eclipse up and running, Kepler and later versions can install WTP through the Marketplace.
Otherwise, within Eclipse, go to the Help menu, choose Install New Software, and while Working With All Available Sites, choose the features you want from the Web, XML, Java EE and OSGi Enterprise Development category. If unsure, select the Eclipse Java EE Developer Tools, JST Server Adapters, and JST Server Adapters Extensions features and proceed, allowing it to select dependencies for you. For more complete steps on installing software, consult the Workbench User Guide Task:Updating and Installing Software.
I understand that I need RCP for eclipse plugin and eclipse RCP development. However, as I have some crashes, and software installation issues, I guess I have to use eclipse classic until the issues are solved.
What makes eclipse for RCP different from eclipse classic?
I checked eclipse download page, and to me it seems like that eclipse classic doesn't have any feature whereas RCP has a lot.
Are the features only difference between the two choices?
If so, can I download the features/plugins to use all the RCP features in eclipse classic without any problems?
All the downloads on the eclipse.org page are only predefined packages of generally available Eclipse plugins. So you can always install any plugin into any existing Eclipse installation (assuming no dependency conflicts). The package selection on the download site only determines what is pre-installed (and it is hard to disable the pre-installed features).
For RCP development you need the JDT and PDE features. Both the "classic" as well as "for RCP development" packages contain those, so it is still your choice.
If you really want a minimalistic Eclipse suited to your needs, then install the "Platform Runtime Binary" from http://download.eclipse.org/eclipse/downloads/drops4/R-4.2.1-201209141800/, which is an "empty" Eclipse. Afterwards install only your chosen plugins using the update manager.
I would like to install both the Google-Eclipse plugin (which I believe also install the GAE SDK) for my Eclipse instance, so that I may take advantage of a lot of the IDE tools and features it comes with, and also so that I can run my app from inside Eclipse.
I would also like to install just the pure GAE SDK so that I can run my app outside of Eclipse on my regular system.
Because the GAE SDK is a diverse and complex beast, I am worried about having two instances of the GAE SDK installed on the same machine (setting conflicting ENV VARs, trying to open the same port number, etc.).
Obviously, I would take care to never be running the 2 GAE dev servers (1 that ships with the Eclipse plugin, and the other that ships with the pure SDK) at the same time, but that might not guarantee that I have 0 conflicts.
I would also be fine with just installing the Eclipse plugin if there was a way to configure the GAE SDK that it ships with to run both from Eclipse as well as the bash shell. That would probably be the easiest but I don't believe this is possible to do.
Any thoughts as to what my options are here? Thanks in advance!
You can do that by having a single SDK installed and using it for both Eclipse and also for bash shell.You can do that by following the steps below:
Download a Suitable GAE SDK from here and install it.
Open Eclipse and Select Help->Install new software.
In work with box enter the url as http://dl.google.com/eclipse/plugin/4.2 and from the list of available softwares select only "Google Plugin for Eclipse" software and select any other required plugin but not the SDKs. Keep it unchecked!
After installing the selected plugins, in Window->Preferences->Google->AppEngine click on add and then select the installation directory as the directory from step 1 and give a suitable name. Make it as default.
Now you are good to go.If you need to run from shell, invoke dev_appserver from the installation directory. Or if you want to run from from eclipse just run it from there.
I have downloaded the Netbeans version of Java (and not JavaEE). Now I need to create a web application using the IDE. Can you please confirm the website to download the plugin and get the JavaEE features in the IDE.
PS: I am looking for URL where I can download the .nbm file because proxy settings may not allow automatic updates.
Try using the plugin manager
Tools -> Plugins -> Available Plugins
If you're having proxy issues then
Tools -> General -> Proxy Settings
and set your proxy settings.
If you do fin the URL for the nbms you can either use the plugin manager mentioned above, or use the update folder as mentioned in Geertjans' blog.
The website that holds the numerous plugins that implement the Java EE features of NetBeans 7 is here: http://dlc.sun.com.edgesuite.net/netbeans/updates/7.0/uc/final/distribution/modules/enterprise/
You may need to get some other plugins from http://dlc.sun.com.edgesuite.net/netbeans/updates/7.0/uc/final/distribution/modules/websvccommon/, too.
I would encourage you to ask questions about the proxy issues that you are running into with the Update Center. Doing the update manually will be a frustrating experience.
My Netbeans is the version from the Ubuntu 12.04 Software Center repository (7.0). I solved this by checking the options "Certified Plugins","Netbeans Distribution" and "Plugins Portal", which, by default, were unchecked for active. You can find this on
Tools -> Plugins -> Available Plugins
In the "Settings" (last) tab.
By making this, reload the "Avaible Plugins" (that was empty for me) and, after some seconds, lots of categories will appear. Look for Java Web and EE and install them (I found only the Java Web plugin).
Which URL do I install this and any pre-reqs from, and how can I install them? Been struggling with this for the last 1 hour with no luck.
new 2013 answer: it seems to depend on what version of eclipse you're running.
click "help" -> "about eclipse sdk" to find the version (e.g. 4.2.2).
optionally, from the version number you can know the codename (e.g. Juno) from wikipedia: http://en.wikipedia.org/wiki/Eclipse_%28software%29#Releases
go here: http://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F
right click on the correct WTP link copy the link address (e.g. WTP 3.4) (they should be listed by version and codename)
now in eclipse, click "help" -> "install new software..." and paste the link location in the "work with" field (e.g. "http://download.eclipse.org/webtools/repository/juno/").
choose "Web Tools Platform (WTP #.#.#)" and click next and install everything.
restart eclipse, close all open files and re-open them for web tools to start working.
If you can use a clean install of Eclipse. Download Enterprise Java version. WTP its included in this Eclipse distribution. When you need updates for WTP, you can get updates via "Eclipse Software Updates" tool.
Regards
You can download WTP from Eclipse Help Menu. Following is the link to download the WTP into Eclipse.

I try my best to stick to Pulse, which handles a lot of the configuration of Eclipse plugins for you. I'm not associated with them by the way, but am very happy with the service. WTP is one of the features they provide.
