SimpleServlets depends upon the ProgramixGenericLib library (a version of which is
delivered as part of the download). After unzipping the download, the file
ProgramixGenericLib.jar is available under the folder: ./SimpleServlets/lib/ProgramixGenericLib/
Or, instead of using the version that shipped with SimpleServlets,
you should be able to use the latest version of ProgramixGenericLib which
can be found here: www.programix.com/ProgramixGenericLib/
