To help
achieve that, I very much suggest matching your environment to that in which the code was
developed. The following is the environment configuration I used. You may well already be
good to go based on the minimums DWR requires, and you can skip this section if your environment
meets the requirements, but if your environment doesn??™t match what??™s described

next to a reasonable approximation, then I very much suggest taking the time to set things up
to match this list, just to avoid any problems.
??? Sun Java SDK 1.6.0_03 (otherwise known as 6u3, or 6 update 3, with a build number of
1.6.0_03-b06): If you do not have this already installed, please visit http://java.sun.
com/javase/downloads/index.jsp and download it. It sure looks to me like Sun is continuing
with their master plan of making the version numbering so confusing as to be
rendered utterly meaningless to virtually everyone on planet Earth, so just download
the latest Java 6 (which is 1.6) that is there. At the time I wrote this, it was SDK 6u3. The
install is a simple matter of running the installer and following the prompts. I personally
like to install my SDK into c:\java, no version number, so that I can swap in
another SDK at any time without updating anything that may be pointing to it.
