in setclasspath.bat at the first line the @echo off ist missing, preventing this script from running and doing its work, leading to compiler not found errors when trying to use jsp ..
Besides the fact it works for me and hasn't been corroborated, every reference I've found, e.g. http://www.dx21.com/SCRIPTING/MSDOS/ViewItem.ASP?OID=11, says @echo off is optional. It shouldn't affect the rest of the script either way.
