I'm creating a c++ Wrapper that will interface with 3rd Party API's.  Those API's create a Java Virtual Machine.  I've utilizing JDK1.4.  

I've set my PATH variable to point to my JVM.DLL file.  

Do I have to set my CLASSPATH environment variable as well for this to operate properly?

The CPLASSPATH should already be set correctly by the JVM's installer. If not, that should definitely be done. You can check if it is set by typing

echo %CLASSPATH%

at the command prompt.

here is my settings:
C:\PROGRA~1\Sybase\ASEP_W~1\3pclass.zip;C:\PROGRA~1\Sybase\ASEP_W~1\monclass.zip;C:\Program Files\JavaSoft\JRE\1.3.1\lib\ext\QTJava.zip

It doesn't reference the jre 1.4 anywhere....  I just uninstalled and re-installed the file and the classpath didn't change.  But I'm not sure what to use...

"CLASSPATH" and "PATH" are completely unrelated. The latter is where the JVM is looking for its files, "PATH" is for the rest...
