Windows command script failing to recognize CD parameter for Java program

I'm trying to run a Java program from a script called converter.cmd but something is wrong.

    P:\LatitudeConsulting\LatConConverter-1.8.2>dir
 Volume in drive P has no label.
 Volume Serial Number is 1074-4BBE

Here is the content of converter.cmd:

cd %~dp0%

jre.1.6.0\bin\java -Xmx1024m -cp Converter.jar com.latcon.ExportConvert.Converter %1 %2

Here is what I get when I type converter at the above command prompt:

    P:\LatitudeConsulting\LatConConverter-1.8.2>converter

P:\LatitudeConsulting\LatConConverter-1.8.2>cd P:\LatitudeConsulting\LatConConverter-1.8.2\

Looks like no java.exe exists - only java.dll

Try jre.1.6.0\bin\java.exe - with the extension.

Try just java or java.exe, your java program might not be in jre.1.6.0\bin.

If it's not in the relative path you're trying to execute it from, copy it there ( assuming that's what you want ).
