Unable to build and run Javapetstore using Sun SDK from Command Line

Question

Hi,
Here is a problem I?ve come across building and running JavaPetstore from Command Line using Ant.
It shows that Build is successful but there is an error message in very beginning:
?Unable to locate tools. jar. Expected to find it in C:\Program Files\Java\jre 1.5.0_11\lib\tools.jar?
But there is no such a file in jre-1.5.0_11 or previous versions.
The only place where the file with such name can be found is jdk\lib.
All attempts to run end up with:
? BUILD FAILED.
C:\<PETSTORE_HOME>\bp-project\command-line-ant-task.xml:77;unable to find javac compiler;com.sun.tools.javac.Main is not on the class path.
Perhaps JAVA_HOME does not point to JDK."
Directories C:\Sun\SDK\bin and C:\Sun\SDK\jdk are in the PATH.
JAVA_HOME as a System variable is set up to C:\Sun\SDK\jdk.
Building and running other applications like a BluePrints or Samples bring to same result.
I will post more information if needed.
Thank you in advance for help.

If you are using Windows XP:
1. Right click on my computer
2. Select Properties from the popup dialog
3. Click on the "Advanced" tab
4. Click the button towards the bottom that says "Environment Variables"
5. In the dialog that pops up, look in both the User variables and the System variables for a variable named CLASSPATH
6. If its not there, you need to create it. If you want to make it available to all users of your computer, create it as a System variable. If you only want it to be available to the current user, add it as a User variable.
7. If it is there, or if you just created it, it needs to contain the following values: the current directory (symbolically abbreviated as a period: "."), any class libraries you want to be available to the java compiler (javac) or the java interpreter (java). By default, jre/lib and jre/lib/ext are searched for classes, so you don't need to include anything located in one of these folders on the classpath.
