Java EE (Java Enterprise Edition) General Discussion

One of the files which I'm attempting to compile calls upon java classes within the following package:

javax.xml.bind.annotation

The classes and package structure is located within the Jar File (which I have added to my classpath) :

C:\Sun\jwsdp-1.6\jaxb\lib\jaxb-api.jar

HOWEVER

When I attempt to compile the files in a DOS Session It flags an error saying that javax.xml.bind.annotation does not exist :

Does anyone have any experience in this or any idea as to other possibilities i may try. I have verified the path of the package that it is correctly structured and the jar file is on my Classpath in Windows and my Path in Dos which I have set using a command in C:\autoexec.bat
