Setting up eclipse on ubuntu

Question

I have a small problem with Eclipse on my Ubuntu machine. I installed JDK, set JAVA_HOME and PATH variables, all seems correct, but eclipse refuses to launch and throws an 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: /opt/eclipse/jre/bin/java java in your current PATH

have no clue what's the problem. help please.

note:

I am able to run java and javac in terminal.

Answer 1

If you get this error even though you already have JDK in your system-just follow this steps:

1)open eclipse.ini file with text editor.
2)copy your jdk path by using -vm command (vm and your path should not be in same line)
eg:
-vm        
/usr/lib/java/jdk1.7.0_75/jre/bin/java 
3)-vm should be placed before -vmargs in eclipse.ini file.

99% works if you follow above simple steps

Answer 2

This worked for me:

ubuntu:~$ sudo apt-get install default-jre

Answer 3

You need to create a link at /usr/bin/java for the java binary (wherever you have placed it).

sudo ln -s /path/to/jre*/bin/java /usr/bin/java
