Can't start Aptana, doesn't find JDK

I added this to my .bashrc, still doesn't work:

PATH="$PATH:/usr/java/default/bin"
PATH="$PATH:/usr/java/jdk1.7.0/bin"

export JDK_HOME=/usr/java/default

This is the error I'm getting:

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: /home/pc/Programming/IDE开发者_C百科s/Aptana Studio 3/jre/bin/java java in your current PATH

I don't even know what that error means, there is no folder called "jre" inside my Aptana download.

Most people might get this error message while installing Aptana Studio 3 for the first time.

But there is a simple solution for it, just follow these given steps:

1. GO TO [java.com][2]
2. Download the latest JRE for your OS **I prefer both x86 & x64
3. Install it
4. Restart your PC
5. Launch Aptana 3
