Check the <code>eclipse.ini</code> file and make sure there is no <code>-vm</code> option there that is pointing to a non existing java install now. You can delete the option to let Eclipse figure out what java install to use or change it so it's pointing to the new install.

This worked with me:

<hr>

Let eclipse use your java vm directly!

Put these lines at the end of eclipse.ini (located in the directory where eclipse.exe is present):

<pre><code>-vm
&lt;your path to jdk|jre&gt;/bin/javaw.exe
</code></pre>

Pay attention that there are two lines. Also make sure that the -vm option is before the -vmargs option (and of course after "openFile").

This problem is because of the fact that eclipse is not able to find Java , 

Check the java directory 
cd /Library/Java/JavaVirtualMachines///Contents/Home/jre/bin

If thats not present down JDK from <a href="http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html" rel="nofollow noreferrer">http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html</a>

Once JDK is installed change eclipse.ini file

On Mac:
Right click on Eclipse icon and click "Show package Content"

Navigate to eclipse>Contents>Eclipse>eclipse.ini

Open the file and replace the java path after "-vm" with this 

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/bin

blocks|key|1718264|text|这似乎与本例无关，但以防其他人遇到此问题-请确保如果您安装了32位版本的Eclipse，则也安装了32位版本的JRE。类似地，如果您安装了64位版本的Eclipse，那么您的Windows中也需要64位版本的JRE。否则，您也会看到上面的错误消息。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1718265|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This doesn't seem to be relevant in this case, but in case others face this problem --- make sure that if you installed 32 bit version of Eclipse, you also installed 32 bit version of JRE. Similarly, if you installed 64 bit version of Eclipse, you need 64 bit version of JRE in your Windows. Otherwise you will see the above error message as well.

If you are using 32 bit eclipse IDE, then u might have to install the "jdk-7u45-windows-i586" version. 

i have tried using 64 bit version JDK but no luck!

I got the same error after a Java version update. I just edited the line after "-vm" in the eclipse.ini file, which was pointing to the older and no more existing jre path, and everything worked fine.

I tried to run <code>"eclipse-jee-juno-win32-x86_64"</code> , but it raised the following error " java runtime environment JRE or java development kit must be available in order to run eclipse. No java virtual machine was found after searching in the folloiwng location ........ ".

Baring in mind that i have both java jre7 and Java jdk1.7.0_06 installed at <code>C:\Program Files\Java.</code> 

The other strange thing also that Eclipse used to run without any problems yesterday , but today i have downloaded the JDK 1.7.0_06 and i set the JAVA_HOME to be "C:\Program Files\Java\jdk1.7.0_06"so i don't know if the problem is related to this ???.

So what might be the problem in running Eclipse?
