On Windows XP

Just downloaed and unzipped google app engine java sdk
to C:\Program Files\appengine-java-sdk

I have jdk installed in
C:\Program Files\Java\jdk1.6.0_20.

I ran the sample application by
appengine-java-sdk\bin\dev_appserver.cmd appengine-java-sdk\demos\guestbook\war

Then I visited localhost:8080 to find :
HTTP ERROR 500

Problem accessing /. Reason:

Error running javac.exe compiler

Caused by:

Error running javac.exe compiler at org.apache.tools.ant.taskdefs.compilers.DefaultCompilerAdapter.executeExternalCompile(DefaultCompilerAdapter.java:473)

How to Fix it?

My JAVA_HOME points to C:\Program Files\Java\jdk1.6.0_20.

I also tried chaning my appcfg.cmd to :

@"C:\Program Files\Java\jdk1.6.0_20\bin\java" -cp "%~dp0..\lib\appengine-tools-api.jar" com.google.appengine.tools.admin.AppCfg %*

It too didn't work.
