Error executing phonegap command cordova build

Question

I'm executing the command "cordova build" (After finishing the above settings, exemplified this link Phonegap The Command-Line Interface).
But the note.js returns this error:

Generating config.xml from defaults for platform "android"
Preparing android project
Compiling app on platform "android" via command "cmd" /c
C:\Net\Phonegap\hello\platforms\android\cordova\build
Error: An error occurred while building the android project.Error executing "ant" debug -f "C:\Net\Phonegap\hello\platforms\android\build.xml"":

com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre7"

My config.xml

<name>HelloWorld</name>
<description>
    A sample Apache Cordova application that responds to the deviceready event.

<preference name="WebViewBounce" value="true" />
<feature name="Device">

</feature>

And my AndroidManifest.xml

<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="com.example.hello" xmlns:android="http://schemas.android.com/apk/res/android">

</application>

What is your question? Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre7" — Simon
My question is, what is missing in the configuration for me to executing command "cordova build". My path like this: — Luanna Iozzi
%JAVA_HOME%\bin;%ROAMING_HOME%\npm;%ANDROID_HOME%\platform-tools;%ANDROID_HOME%\tools;%ANT_HOME%\bin JAVA_HOME -> C:\Program Files\Java\jre7 — Luanna Iozzi

It looks like you currently have the Java Runtime Environment (JRE) installed. You need the Java Development Kit (JDK). You can get that over at Oracle. Your path does appear to be set up correctly with %JAVA_HOME%\bin. I believe once you install the JDK, your %JAVA_HOME% environment variable will be changed to something similar to: C:\Program Files\Java\jdk1.7.0_52. The version number might be slightly different of course.
