Google Apps Engine com.google.appengine.tools.admin.JspCompilationException: Failed to compile jsp files.

My Google Apps Engine was working fine till I installed Windows 7 (62 bit). After shifting to Windows 7, when I tried to deploy my GAE code to google, I got below error:

------------ Deploying frontend ------------

Preparing to deploy:
Created staging directory at: 'C:\Users\sbinod\AppData\Local\Temp\appcfg5079868666950863187.tmp'

I tired many solution like to upgrade GAE SDK to 1.8 and re-installed Java 6 in different folder and change some script into appcfg.cmd, BUT did not worked.

Then I changed my laptop path variable and kept my jdk path before C:\Windows\system32.
So, simply I went to start -> Computer -> Right Click -> Properties - > Advanced System Settings ->
Environment Variable  -> Inside System Variable -> click on Path variable -> Click on Edit button -> Add these path (as per you system) C:\Java\jdk1.6.0_39\bin; at first. -> ok.
Restart Eclipse then try to deploy your code to Google.

Second thing, copy tools.jar from your java JDK (in my caseC:\Java\jdk1.6.0_39\lib\tools.jar) to your Apps Engine SDK (E:\Software\Google_Apps_Engine\appengine-java-sdk-1.8.0\appengine-java-sdk-1.8.0\lib\shared)
