Personally I have intentionally set it up to use the JRE from within the SDK by modifying appcfg.cmd to
"%JAVA_HOME%\bin\java" -Djava.home="%JAVA_HOME%\jre" -Xmx1100m -cp "%~dp0\..\lib\appengine-tools-api.jar" com.google.appengine.tools.admin.AppCfg %*
and setting JAVA_HOME to point to the JDK.
I am guessing you could modify -Djava.home="%JAVA_HOME%\jre" to point to wherever you like.

"Unable to update app: Failed to compile the generated JSP java files." when trying to deploy GAE App

I did my reading before posting
I know there are quite a few questions on this issue.
I have read all those that I could find but non of the issues and suggestions there helped.
My environment
windows 7 64bit
GAE SDK 1.8.8
version 1.7.0_45 of the JDK
eclipse kepler 4.3.1 + google plugin.
Stuff I tried already
Here are the things I have already tried:
1) changed system variable JAVA_HOME to point to C:\Program Files\Java\jdk1.7.0_45
2) ensured the system variable PATH contains C:\Program Files\Java\jdk1.7.0_45\bin
3) when opening a command window and running both java -version and javac -version I get:
C:\Users\epeleg>java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
C:\Users\epeleg>javac -version
javac 1.7.0_45
4) checked that all my JSP pages (there are only 2) are working properly when used in development server
5) modified C:\Program Files\GAE\appengine-java-sdk-1.8.8\bin\appcfg.cmd so that the command inside it starts with #%JAVA_HOME%\bin\java ... instead of java...
6) I opened the Markers Pane (eclipse: window - show view - other... General--Markers) and fixed all the Java issues that where mentioned there no matter how trivial they seemed.
What the logs show
The Deploy process reports:

The "Staging directory" seems o.k. (but maybe there are missing libraries there ?!)
and the log file contains the following text:

My Questions
1) looking for ideas regarding what else I can try
2) Is there a way to simulate the compile from a command window directly on the staging folder so that I might hopefully see an actual helpful error message?
3) The error says Failed to compile the generated JSP java files - where are those generated files supposed to be?
4) Is there a way to run appcfg.cmd directly from the command line (and with what parameters) so that I can see its output (assuming that the plugin is hiding some stuff from me...).
Problem solved
Here is what I did to resolve this, hopefully it will help others that have similar issues.
I decided to try and run the upload from the command line instead of using the plugin for it.
And here is what I got:
[note that I added rem to the #echo off command and also removed the # from the begining of the java command in appcfg.cmd so that all the commands would echo to the console]
C:\Program Files\GAE\appengine-java-sdk-1.8.8\bin>appcfg.cmd update "X:\path\to\my\project\war"

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
OK, so I edited appcfg.cmd again and changed its last line to look like this:
"%JAVA_HOME%\bin\java" -Djava.home="%JAVA_HOME%\jre" -Xmx1100m -cp "%~dp0\..\lib\appengine-tools-api.jar" com.google.appengine.tools.admin.AppCfg %*
Try again:

So I went to my JSP's, removed the offending import attribute from the page tag, tryed again and this time it worked.
Now, I don't know why the plugin fails to display the most important lines in appcfg.cmd's output, but to me it feels like some sort of a bug.
Two lines Summary
run <path-to-appengine-java-sdk>\bin\appcfg.cmd update <war-location> in a command window,
it will provide you with a more detailed output then the plugin does and will most likely enable you to resolve the problem in a matter of minutes.
If that fails you are welcome to follow all the steps I mentioned in the questions body, hey seem to have helped other people in the past.

Exception Processing Mirror-Quickstart

I ran the mvn war:war in the command prompt, I then went to upload to appengine using appcfg update and I got this error. The app works on localhost. Aside from the path simply being wrong, there is no appengine-web.xml. Any help would be appreciated thankyou.

Google App Engine Tutorial Hello World Example won't run

I am having difficulty getting to the starting line on my machine.
1) Windows 7 32bit all service packs installed
2) Installed JDK 1.7.0_21
3) Checked PATH that only one copy of JDK\bin is in path and that it is correct.
4) Installed Eclipse Juno Java bundle. eclipse-java-juno-SR2-win32.zip
5) Install Google App Engine SDK per the tutorial using:
https://dl.google.com/eclipse/plugin/4.2
Selected:
- Google Plugin for Eclipse
- GWT
- SDK
Did NOT select:
- Developer Tools (Android)
- Google App for Android
- NDK Plugins
6) Following the tutorial, pull down the Google Icon and select "New Web Application Project"
- Name it Guestbook as shown
- Uncheck GWT
- Check Google App Engine
- Finish
7) Following the tutorial, Run as Web Application
At this point, the console shows several successful steps and then crashes and burns with jetty unable to establish a loop back connection. The full console output is attached below. I have searched all over the web and have not been able to find anything. I checked PATH and JDK. I checked the Windows firewall rule for Eclipse, it looks OK. I looked at the Classpath tab but could not see anything obviously wrong (although I don't know what it is supposed to look like)

PROBLEM SOLVED!
I was able to absolutely nail the cause of this problem and fix it.
What I did was removed the JRE and JDK from "C:\Program Files\Java\" (which is where Oracle's installer puts them by default) and reinstalled them in "C:\Java\Java7\" Apparently something in Eclipse and/or the Google Android development kit is still sensitive to spaces in the pathname to the JDK. This is an ancient general problem with Eclipse reported around 2005.
I did NOT need to drop down to Java 6
I did NOT need to edit Eclipse.ini and add a -VM line
I did NOT need to manually add the path to the jdk to PATH
Hope this helps the next person because this is an incredibly frustrating problem when you encounter it.
Thanks!
David Hetherington
Problem: Trying to run the 'Hello World' app using google eclipse plugin (eclipse - Kepler).
Solution: Adding to David's answer. If you have multiple jre's installed make sure the jre you are pointing to does not have a space in the absolute path. To change the jre you are pointing to go to eclipse - window->preferences->server->runtime environments->google app engine->edit. Now check the jre version you are pointing to. In my case I had jdk 1.7 installed in Program Files/Java and jre6 and jre7 installed in the same location. I moved jdk 1.7 to Program_files but was still getting the loopback error. Followed the above steps and pointed the jre version to the one in jdk1.7/jre in Program_files/java as earlier it was pointing to C:/Program Files/java/jre7
Hope this helps someone.
Are you sure you don't have anything else running with the same PORT number as the web-application? Default webapplication PORT is 8888

Yesterday it was working fine but today I got these errors. I saw a known issue with this - link. But I didn't find any solution yet..

If you are using Java 8 in your app engine application, you will need to include
<url-stream-handler> urlfetch </ url-stream-handler>
in appengine-web.xml.
appengine-web.xml Reference
I am assuming that you are seeing this in your Eclipse IDE when you are trying to run the Eclipse Project as a Web Application.
The GAE plugin simply checks if there is an updated AppEngine SDK available for download. If there is a newer one than the one you are currently using then it lets you know that. The error is because at that instance, there was probably a network error and it got not connect through. It is harmless as far as running your application is concerned.
But if your application is dependent on accessing some external network services, then chances are that they might fail also if the network issue persists in your development environment.
got it working.. : cmd->goto your home directory >mkdir .appcfg_no_nag this will stop checking for the update and yourweb app willrun locally atleast..
This error is related to internet connection. I changed to other connection, it works
You should add in appengine-web.xml:
<url-stream-handler> urlfetch </ url-stream-handler>
And also start using java.net.URLConnection,
Apache HttpClient is not gonna work for example.

App Engine doesn't find WEB-INF in WAR created by sbt

I'm trying to make a Lift app that I can run on App Engine and am managing the project with sbt. I have web.xml and appengine-web.xml in src/main/webapp/WEB-INF and package the project with sbt project. According to a previous SO quesiton, that should be all I need. However, I get this:
$ dev_appserver.sh target/scala_2.8.1/

Any ideas why? Thanks.
Sorry, I just figured out the problem after submitting the question. The following invocation of the dev server works: dev_appserver.sh target/scala_2.8.1/webapp
