Ubuntu: Aptana unable to find java



Question:

I am getting the following errors when i am running aptana

A Java Runtime Environment (JRE) or Java Development Kit (JDK)  must be available in order to run AptanaStudio3. No Java virtual machine  was found after searching the following locations:  /opt/aptanastudio3/jre/bin/java  java in your current PATH  

.

300E7Z:~$ java -version  java version "1.7.0_03"  Java(TM) SE Runtime Environment (build 1.7.0_03-b04)  Java HotSpot(TM) Server VM (build 22.1-b02, mixed mode)  

My JDK path is /usr/local/jdk1.7.0_03


Solution:1

What works for me
Install Eclipse from repository
sudo apt-get install libjpeg62
Install the plug-in instead of the portable
It all just works.


Solution:2

I had OpenJDK when i installed aptana. So i installed SunJava and this helped but still not much . Doing aptana -vm /path/to/sunjdk helped. But i wanted something simpler. So this is what finally helped me.

Uninstalling Aptana and restart the sytem.

Now install aptana again

My Ubuntu 12.04 also displayed the same error. I followed the instructions from the Thumbring blog and I could start Eclipse after that.

Run the following command:

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-sun/bin/java 300    sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-7-sun/bin/javac 300    sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/java-7-sun/bin/jar 300     sudo update-alternatives --install /usr/bin/javah javah /usr/lib/jvm/java-7-sun/bin/javah 300     sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jvm/java-7-sun/bin/javap 300     

And then, run this command:

sudo update-alternatives --config java    


Solution:4

Aptana is attempting to locate a JRE at the location /opt/aptanastudio3/jre/bin/java. However, there is no JRE at that location.

Create a symlink that points Aptana to the actual location of your JRE:

ln -s /usr/local/jdk1.7.0_03 /opt/aptanastudio3/jre/bin  

This should then mean that you can locate the java executable at the path: /opt/aptanastudio3/jre/bin/java. This assumes the directory /opt/aptanastudio3/jre/ and /opt/aptanastudio3/jre/bin exist. If they don't, you'll need to create them.
