Unable to deploy app to App engine

Question

I have a GWT based web application that I have previously uploaded to Appspot. However now, I am getting this error:

Unable to update:
com.google.appengine.tools.admin.JspCompilationException: Failed to compile jsp files.
    at com.google.appengine.tools.admin.Application.compileJsps(Application.java:583)
    at com.google.appengine.tools.admin.Application.createStagingDirectory(Application.java:434)
    at com.google.appengine.tools.admin.AppAdminImpl.doUpdate(AppAdminImpl.java:327)
    at com.google.appengine.tools.admin.AppAdminImpl.update(AppAdminImpl.java:52)
    at com.google.appengine.eclipse.core.proxy.AppEngineBridgeImpl.deploy(AppEngineBridgeImpl.java:400)

    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

The application used JDK (not JRE)
There's a JSP file (dummy) on the war file
The application works in hosted mode

encountered same problem after upgrading to appengine SDK 1.7.5 — JR Galia, Mar 19 '13 at 06:22
I had the same problem; I use manual compilation with batch files. I tried the ant build file and ran ant clean. That solved the problem. — user2694186, Oct 03 '13 at 15:14

Do a clean build first. Alt+P, N in eclipse. If this fails, delete /war/WEB-INF/classes and try again. If this also fails, right click your war folder and select validate; this will tell you if there are any actual errors in your jsp files.

If this fails, your appengine jars may be corrupted. Try unzipping a fresh SDK and using it to deploy.

Also, have you changed java versions recently? Compiling JSPs requires JAVA_HOME points to a JDK, not a JRE. What is the result of echo $JAVA_HOME?

I did, still getting the same problem – quarks May 01 '12 at 03:29
If you've had any IDE crashes, they can sometimes randomly corrupt your appengine jars. Try unzipping a fresh sdk, and using it to deploy instead. If you aren't already, try the command line deploy, `/path/to/sdk/bin/appcfg.sh update /path/to/project/war` I also get this problem if eclipse is compiling my files while I try to deploy. Make sure your IDE isn't doing anything in /war when you try. – Ajax May 01 '12 at 07:55

this thread will solve your problem Cannot get the System Java Compiler. Please use a JDK, not a JRE

Other wise, you need to set your JAVA_HOME to point to your jdk folder and add javaw.exe path in your eclipse.ini
