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.
