problem running eclipse on ubuntu?

Question

I downloaded eclipse on ubuntu. But when I run it it show following error.

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/home/awan/eclipse/jre/bin/java
java in your current PATH

Can someone help me to solve this. I don't have experience about this on ubuntu.

thanks

Answer 1

If you allready installed java** you need to add the Java-Path to your eclipse.ini

in my case it's located at:

/usr/lib/eclipse/eclipse.ini

there you need to add direct under the "openFile" statement, where you replace the path with your java path:

-vm
/usr/lib/jvm/java-7-openjdk/bin/java    //!replace with your path to java!

** check wether java is installed by typing the commands

java -version 

or

javac -version

If you are sure that java is installed, but it's not found you may have multiple versions installed, check that by:

sudo update-alternatives --config java

and select installation first

Answer 2

I solved it by created a symbolic link java in /usr/bin that points to the VM.

Steps :

1. Downloaded the appropriate version of Oracle's JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html?ssSourceSiteId=otnjp

2. extract it to any folder. For example :

   tar zxvf ~/Downloads/jdk-8u5-linux-x64.tar.gz ~/DEV

3. create symbolic link with name java :

   cd /usr/bin

   ln -s ~/DEV/jdk1.8.0_05/bin/java java

Answer 3

You need to add the JDK to your PATH.

This link should help you get started.

Answer 4

First of all you need to set your JAVA path in .bashrc file. goto cd ~ open .bashrc,vi .bashrc add a line at the end export path="path/to dir:$path" do source .bashrc for changes to take effect.

Then open your eclipse.ini file(if you want to locate eclipse.ini do whereis eclipse). open eclipse.ini,then add a line

-vm
"path/to/bin/of/open-jdk"
