I am trying to add Tomcat 10.1.1 in Eclipse Version: 2022-09 (4.25.0).
Is there a newer version of Eclipse which have latest Tomcat?
This was happening in older version of Eclipse IDE for Enterprise Java and Web Developers. This issue is corrected in the version 3.28 of Eclipse IDE for Enterprise Java and Web Developers.
If you have the Standard Edition of Eclipse, you can add
'Eclipse IDE for Enterprise Java and Web Developers'. This will add the version 3.22 of the software. You can then check for updates and update it to version 3.28
I want to start using Java 8 with Eclipse but I don't know how to install it - I can't find any tutorials on it. I am using Eclipse Kepler and have added a JRE for JDK 8 to the IDE but it won't let me continue to create the project because of a compliance problem with the JRE versions. How can I use Java 8 with the Eclipse Kepler IDE?
Have a look at this bug report from time to time for progress on Java 8 in Eclipse's JDT.
EDIT: For Kepler you need SR2 (4.3.2) and the Java 8 feature patch. Starting with I20140318-0830 all Luna (4.4) builds contain support for Java 8 "out-of-the-box". The final version of Eclipse Luna (4.4) will be released at the end of June 2014.
Now, after Java 8 is released, there is a feature patch, but only for Kepler SR2 (4.3.2). Installation via
Help > Install New Software... > 'Work with': http://download.eclipse.org/eclipse/updates/4.3-P-builds/
see Tutorial Installing Java 8 on Eclipse Kepler
Early access builds of Eclipse with Java 8 support are available. Installation instruction can be found here.
Wayne Beaton (Director of Open Source Projects at the Eclipse Foundation) just published (February 2014) an article on "Building and Running Java 8 Support" (with Eclipse Luna 4.4Mx).
It includes:
Getting the sources of JDK8
Downloading the latest milestone of the Eclipse SDK (4.4Mx)
Configuring the “vm” option in the eclipse.ini file to use the Java 8 JRE included with the downloaded JDK.
Adding Egit
Clone the BETA_JAVA8 branch of the Git repo JDT Core, JDT UI and JDT Debug repos.
Using the handy “Import all projects” feature to automatically pull all the code into my workspace.
Setting various JRE 1.4, 5 and 6.
Putting the right mapping for those JRE in the execution environment.
For Eclipse Kepler 4.3+, leeor mentions in the comments:
As of Feb 21st, you can install the beta 8 JDT via "install new software..." in Eclipse (I use Kepler) here: JDT/Eclipse Java 8 Support (BETA)
http://build.eclipse.org/eclipse/builds/4P/siteDir/updates/4.3-P-builds
Java8 support for Eclipse Kepler SR2 has been removed from eclipse marketplace. You can access the archive here. Download the zipped repo and install it as a local archive update site.

Add it like the screenshot
I am assuming that you have installed Java 8, JRE 8 and configured them (setting class paths etc.).
Follow the steps.
Go to Help->Eclipse market place
In the search box type "java 8 kepler"
The first link that appears is Java 8 support for Kepler SR2
select it and install it.
It will take a few minutes.
You may need to restart Eclipse after completion.
The problem is that the version of Kepler your using might not have the support for Java8. You can either install the Java8 Patch from market place if your using SR2 version
or
You can directly download Eclipse Kepler SR2 from here, which comes with default support for Java8
I'm trying to use new feature of JRE8 like lambda expression but it causes an error. Is it because my IDE's version not supported? Here is my version of Eclipse.
Eclipse Java EE IDE for Web Developers.
Version: Kepler Service Release 1
Build id: 20130919-0819
Eclipse Kepler does not support the new Java 8 features. The Eclipse Newsletter says there is scheduled to be an update to the Eclipse JDT (Java Development Tools) when Java 8 is released in March.
There is some more detail on the JDT Java 8 Wiki
I wish to find out does anyone have problem compiling JDK 7 code with Eclipse? Because currently I only able use JRE 7 in Eclipse to test run but as for trying to use JDK 7 features into my code, it will state it will not support.
Eclipse 3.8 M1 (Juno) is the earliest stable version to have support for Java 7. Java 7 support will also be available in the upcoming 3.7.1 release.
Unfortunately, since Java 7 released after Eclipse 3.7 (Indigo) release, the Java 7 support could not make it to 3.7.
I downloaded Eclipse plain Java version and now I realize that I need of Eclipse IDE for Java EE Developers distribution.
I'm new in Eclipse world and I would to know if it is possible (and how) to install Java EE plugins via Eclipse.
There is a thread in ServerFault that shows how to install the Java EE pluggins for Eclipse Java EE plugin for Eclipse IDE
Additionally you can:
Help -> Install new software.
Pick the Mars (or the version you have downloaded such as Luna, Kepler, etc) repository
At the bottom there are install options Java EE Development
To get all of the features of the Java EE edition of Eclipse, there are several packages that need to be installed. This page lists all of the packages that are included in the current Java EE version of Eclipse. If you want all of the features of the Eclipse for Java EE developers, go to Help --> Install New Software..., select the update site for your version (e.g. Kepler) from the dropdown menu, and select the checkbox for each item listed on the above page that is not already installed.
You'll probably find the 'getting started guides' here helpful.
You probably will need to download the plug-in. The easiest way to do this would be to:
go to Help -> Install new software.
Pick the Galileo(Change accordingly) repository
All the way at the bottom there are install options for 'Web, XML, and JaveEE Development

Eclipse 3.3 or earlier, it is NOT possible to upgrade the Eclipse platform itself, only its features. So, you could for example upgrade the CVS feature or the PDE feature from 3.2.0 to 3.2.1, but not eclipse.exe itself.
and
Upgrading other features (like CDT, PDT, WTP...) can be done without the need to download a new platform binary, but because many projects align very closely (eg., the Eclipse 3.2 / Callisto or Eclipse 3.3 / Europa release trains) you will likely need to upgrade the Eclipse platform as well.
