Trying to run jar file but getting cannot find class

I am trying to run a jar file from the Win7 command line, but am getting the dreaded could not find or load main class PRCreateExecution.

I can successfully build the jar file from a Win7 batch file on the command line.

My current manifest file is named PRCreateExecution.mf and is located in here: C:\WDEclipseIDEWorkspace\MC3\src\PurchaseRequests\

The manifest file contains:

Manifest-Version: 1.0
Created-By: 1.8.0_40 (Oracle Corporation)
Main-Class: PurchaseRequests.PRCreateExecution.class

(extra LF is here)

I run the Win7 batch file to build the jar from C:\WDEclipseIDEWorkspace\MC3\src\PurchaseRequests:

jar -cvmf PRCreateExecution.jar C:\WDEclipseIDEWorkspace\MC3\bin\PurchaseRequests\PRCreateExecution.mf C:\WDEclipseIDEWorkspace\MC3\bin\PurchaseRequests\PRCreateExecution.class C:\WDJarFiles

The jar file gets created successfully.

Now I'm using this batch statement to try and run the jar file:

java -cp C:\WDEclipseIDEWorkspace\MC3\bin\PurchaseRequests;. PurchaseRequests.PRCreateExecution

from in here:

C:\WDEclipseIDEWorkspace\MC3\src\PurchaseRequests

but am getting the could not find main class PurchaseRequests.PRCreateExecution.

PRCreateExecution source snippet:

package PurchaseRequests;
public class PRCreateExecution {
public static void main(String[] args)

Thanks for any help...
