What are the features or functionality which is present in Rational Application Developer and not in Eclipse? Why is Rational Application Developer needed?
By default Eclipse is only Java development environment not Java EE, so to develop for Java EE you need Eclipse bundle for Java EE developers. RAD is based on that, plus has many other features more strictly related to developing and deploying applications to various WebSphere products.
Here is short list with additional features in RAD (it is not complete list and might change in detailed comparison between specific RAD and Eclipse for Java EE versions):
Programming support extensions
Enhanced JSF tooling
SCA, SIP, OSGi, WebSphere Batch tooling
Portlet and Portal theme tooling
JCA wizards (creating custom JCA adapters)
Jython editor for creating WebSphere wsadmin scripts
Modeling and analysis extensions
UML visualizations
Code coverage tools
Static code analysis
Some extensions in profiling tools
Deployment extensions - provided testing environments and server tools for:
WebSphere Application Server 7.0, 8.0, 8.5.5
WebSphere Liberty - new lightweight runtime
WebSphere Portal
Tools to support deployment to Bluemix
You can see whats new here - RAD 9.1 new features and enhancements
If you plan to buy WebSphere Application Server, you might be interested in
the Tools Edition license, where in addition to server licenses you get unlimited number of RAD licenses for development for that runtime.
UPDATE
If you just need server support in Eclipse there is WebSphere Developer tools plugin for Eclipse, freely available via Eclipse Marketplace, which supports WAS 8, 8.5, 9 and WebSphere Liberty.
Eclipse doesn't have a server built-in to run the web app on. RAD is Eclipse + some more features.
RAD is a commercial Eclipse-based IDE, developed by IBM. At a very high level, in RAD, WebSphere comes bundled and you can deploy your web application on the WebSphere server itself. If you are working on an application which is actually deployed on IBM WebSphere server (in production), you can use RAD to avoid surprises which might occur post deployment.
However, deployment on WebSphere in RAD is a time and resource consuming process.
If you want to check free alternatives, you can use Eclipse and a Tomcat server.
You could read more about RAD on the Wikipedia link and also on IBM website.
Long answer short. If you have Websphere server in your enterprise you are better off using RAD but if you don't then just use Eclipse. The additional tooling in RAD over Eclipse is primarily for IBM product (WAS, Blumix, WID, ..) support.
(I have been working with Eclipse ever since its inception, back in the happy WSAD days)
The more IBM products you use — the likelier you are to get any benefit by using RAD.
If your usage of IBM products is restricted to WebSphere Application Server, then don't bother. The JavaEE spec is mature enough and Eclipse's WST / JST do a very good job.

Trial version SAP HANA Cloud Platform Cockpit
Please forgive me if the question sounds naive but I'm been a .NET Developer for past few years, and I'm trying to learn SAP Hana Cloud technology.
I've learned that you have to develop code on Eclipse Java EE IDE for Web Developers in order deploy to the Trial version SAP HANA Cloud Platform
I was trying to use Tomcat 8.5 in my local development environment.
How can I add the the Apache Tomcat v8.5 icon taht is missing from the list within the "New Server Run Time Environment"?
The version of Eclipse WTP that supports Tomcat 8.5 is not out yet and is expected in the 1st maintenance release.
If you need it sooner, you can find instructions on how to get it to run in this bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=494936
I am not familiar with the IBM product. I am currently use Tomcat as the server for my localhost. Now I would like to test in WebSphere 8.5. But in Eclipse, I could only choose Tomcat as my server. I would like to ask how to install and test in WebSphere 8.5. My eclipse version is indigo.
You will need to install WebSphere Developer Tools in Eclipse via Marketplace (search for WebSphere developer tools indigo).
Then you will need to get runtime, if you dont have it:
for full version download WebSphere Application Server v8.5.5.x for Developers (which is free),
or you can use WebSphere Liberty Profile (a new lightweight version that supports Java EE 7, but doesn't contain some old WebSphere programming extensions).
My Dev Env as below.
Eclipse Juno with Webshpere Developer tools plugin
WebShpere 8.5
I have a project with below facets.
EJB Module 2.1
Java 1.6
WebSphere EJB (Extended) 8.5
When I used "prepare for deployment", there's nothing happened that those stubs class weren't generated. After searching in Internet, I realized that Webshpere Developer tools 8.5 just supports EJB 3.0 or greater.
My project was migrated from WAS6.1 which the tools can support EJB2.0.
Now I don't want to upgrade my project to EJB3.0.
Can anyone help to raise a solution? A extra deployer plugin or something?
Thanks in advance.
Here are possible solutions:
Deploy during installation
You can continue to develop your application in WDT, then export your application as ear. When you install your application to WebSphere, there is an option to Deploy enterprise beans during. If you check that option WebSphere will generate required classes during application installation.
Run ejbdeploy command or ant wsejbdeploy ant task.
Once you have your ear, you can run ejbdeploy commandline tool to generate code, or if you are building your application using ant you can use ant task for this.

Use IBM Assembly & Deploy Tools for WebSphere Administration v8.5 tool
If you have WebSphere Application Server license, then you can download additional tool - IBM Assembly & Deploy Tools for WebSphere Administration v8.5 tool - this is simplified RAD (Rational Application Developer), based on Eclipse. which will allow you develop your Java EE application and also generate deployment code.
Here is brief description of functionality of the older version of this tool:

What is the equivalent of sysdeo for developing applications in Eclipse Helios for Websphere 7?
I am looking for a plugin that allows the deployment and debugging of Java EE applications in Eclipse using WebSphere.
You need to have Eclipse IDE for Java EE Developers (not necessarily Juno) edition and install WebSphere® Application Server Developer Tools.
Another option is to use Rational Application Developer for WebSphere Software which is an Eclipse based environment for developing WebSphere applications.
I need to set up an Eclipse WTP project pointing to a WAS V7 instance but I can't find the server adapter to work with version 7. Version 6 is supported.
I believe this answer comes late in the day, but it is put down to help others understand how WTP support for WebSphere works in Eclipse.
WTP support for the newer versions of the WebSphere Application Server come only with commercial IDEs - Rational Application Developer, for example. MyEclipse is another IDE that comes with support for WAS 7; one would need the Blue Edition to work against a v7.0 WAS instance.
The philosophy is that if the vanilla Eclipse WTP project has to support an application server, then the application server vendor must either provide the adapter or some means to perform the integration. For obvious reasons, this is absent for WAS 6.1 and 7.0, but available for 6.0.
This was the case, but IBM has since release WebSphere Application Server tools edition and has donated a server adapter to the Eclipse market place. This will cover WAS 7, 8 and 8.5 alpha.
