Eclipse - no Java (JRE) / (JDK) … no virtual machine

Question

I am trying to get Eclipse v3.5 (Galileo) to re-run on my computer - I have run it before with no problems, but now I keep getting this error:

Answer 1

Open up Windows' System Properties from the control panel and hunt down the environment variables section:

• Add a JAVA_HOME entry pointing to the directory where the JDK is installed (e.g. C:\Program Files\Java\jre6)
• Find the Path entry and add the following onto the end ;%JAVA_HOME%\bin
• OK the changes
• Restart eclipse so that it is aware of the new environment

Most Java tools will now be able to find your Java installation either by using the JAVA_HOME environment variable or by looking for java.exe / javaw.exe in the Path environment variable.
