The shrink wrapped copy of WebObjects is for Windows NT, Solaris, and HP platforms. WebObjects that comes with Mac OS X Server is only for Mac OS X Server. These two versions of WebObjects are functionally equivalent, but have been compiled for use on different platforms. However, it is possible to develop a WebObjects application on one platform and then deploy it on another.
Both WebObjects packages come with serial numbers, but the serial number from the Windows NT/Solaris/HP package will not work with the Mac OS X Server WebObjects package, nor will the serial number for the Mac OS X Server WebObjects package work with the Windows NT/Solaris/HP package.
To upgrade either WebObjects package to a higher number of transactions and multithreading, a new license will need to be purchased. The upgraded serial number can be obtained by calling 1-800-879-6398 and pressing Option 2. International customers should check
