I am new to java and to get my project working I need eclipse, java, tomcat and maven. I am using Ubuntu. Is there any particular order for installations? Is there any place I can get a detailed read about it?
To install JDK (Java Development Kit): http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
To install JRE (Java Runtime Environment): http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
To install Eclipse: https://www.eclipse.org/downloads/
To install Tomcat: https://tomcat.apache.org/download-90.cgi
You need to install JRE first because Eclipse is built with Java. Select the appropriate pacgakes to the Ubuntu OS in the download pages.
Maven is included in the Eclipse EE environment.

I have installed Netbeans 8.0.2 and it doesn't find the JDK installation path.
I suppose I have done all the steps correctly. Netbeans insists that I haven't installed the JDK.
How can I solve this issue?
[
This error exists because, you haven't configured the Environment Variable on your PC, that's why NetBeans is not detecting it. I recommend you to check this link.
Or you may Uninstall/Delete the existing NetBeans and JDK installer and download and install from here. It has package already linked with JDK, so you don't have to configure it later.
Intellij IDEA is installed on Windows. The java application built with maven requires native libraries (with JNI) and runs on Ubuntu.
Using maven and git on Windows is fine. How can I point Intellij IDEA to use the JDK from WSL so I can create a run/debug configuration that uses the WSL?
Deploy your app on WSL with Power Shell, and remote debug
Install Intellij IDEA with version >= 2021.1.
Configure WSL. To work with WSL 2, your Windows version should be 10 build 18917 or later. Make sure you add the needed JDK version in WSL. In order to use Maven, You also need to add a path variable export M2_HOME=/path/to/maven to the .profile file.
Create, open and develop the project in corresponding WSL environment.
Select the project SDK as the JDK configured in WSL.
Ensure that firewalls allow connections using WSL.

I have installed java and eclipse in my raspberry-pi.
Installed eclipse using
sudo apt-get install eclipse
Eclipse is installed and i am able to open the IDE through VNC.But there is no run configurations set in eclipse.It is asking for new run configurations.
Even in the run configuration there is no JRE option.
I also want to add external jar files.Searched the web but didn't get much for eclipse configuration on raspberry-pi
Looks like you have the absolute minimum version of Eclipse installed which does not have the Java Development Tools installed.
You should be able to install this in Help > Install New Software, work with the main Eclipse site and install Eclipse Java Development Tools (under Programming Languages).
I have installed several jre's and jdk's on my computer.
Today I set up grails version 2.3.4.
I have downloaded and installed the grails plugin on a new eclipse kepler.
However, when I start eclipse I get:
How to change to an jdk in eclipse?
I appreciate your answer!
UPDATE
As you can see the jdk should be properly configured:
you have to set the path of the eclipse-vm to a jdk (i.e. the vm with which eclipse is started) in the eclipse ini like described here.
I'd like to install Eclipse on Ubuntu for Java development. I'm happy to trade having the newest version for steady updates via package management.
I've done the usual sudo apt-get install eclipse eclipse-jdt (java-7-openjdk-i386 is installed and working)
However, when I start Eclipse, there seems to be almost nothing available - no Java editing (not even 'Installed JREs' is present under Window/Preferences). I've tried adding various update sites, installing Marketplace client, WTP, Java EE etc. but just can't get a working install. Oddly, I have it running fine on another machine I set up about a year ago (with the help of How do I install Eclipse Marketplace in Eclipse Classic?)
I've given up and reverted to a manual install (along the lines of Eclipse 3.6 Helios for Ubuntu 10.10) but wanted to ask:
Am I missing something obvious?
I strongly recommend you not to install Eclipse in that way, it is not really useful and you will get just the Eclipse with the Java Standard Perspective. What I recommend you is to download the tar.gz file from the page (including the Java EE perspective). Copy the tar file in a directory where you want all your development tools, like /home/user/dev/eclipse and start from there. You can create a launcher in your desktop to get a faster access to the IDE. When I started with Ubuntu, I used to install the way you had installed (sudo apt-get...) but I can tell you that the best way to do is to install it manually. If the JDK is well installed, you will not have any problem launching your Eclipse. Best regards.
