[eclipse] Installing J2EE into existing eclipse IDE

I have Eclipse Galileo (Version: 3.5.2), which I use to develop Jave SE applications. I want to learn Java EE. How do I incorporate Java EE? Or do I need to install a Java EE specific Eclipse IDE?

Thanks a great deal for answering! There are a lot of names in the list that shows up in Eclipse. E.g. WTP 3.1.1, WTP 3.1.2, Patches, WTP Test 3.1.1, WTP Test 3.1.2. Which ones do I download?

Go to Help -> Install new softwares-> add -> paste this link in location box http://download.eclipse.org/webtools/repository/luna/ install all new versions..

For Eclipse Mars the following worked

1. In Eclipse select Help - Install New Software.
2. Search for "EE". Got two hits and it what obvious which to use.
3. Let IDE restart.

For Mars (Eclipse 4.5) and WTP 3.7 use this link. http://download.eclipse.org/webtools/repository/mars/

1. In Eclipse select Help - Install New Software.
2. In the "Work with:" text box place the above link.
3. Press Enter.
4. Select the WTP version you need (3.7.0 or 3.7.1 as of today) & follow the prompts.

You could install Web Tool Platform on top of your current installation to help you learn about Java EE. Download the Web Tools Platform by using Eclipse Software Update (Instruction at http://download.eclipse.org/webtools/updates/). It has features to get you going with learning Java EE. You could learn more about Web Tools Platform at http://www.eclipse.org/webtools/

http://download.eclipse.org/webtools/updates/ - This is an old URL and doesn't work any more. If you want to install WTP (i.e. J2EE plugins) use the following URLs depending upon the version of the eclipse you are using:

• For Neon (Eclipse 4.6) and WTP 3.8 - http://download.eclipse.org/releases/neon/
• For Luna (Eclipse 4.4) and WTP 3.6 - http://download.eclipse.org/releases/luna/
• For Kepler (Eclipse 4.3) and WTP 3.5 - http://download.eclipse.org/releases/kepler/
• For Juno (Eclipse 3.8/4.2) and WTP 3.4- http://download.eclipse.org/releases/juno/
