Java Runtime errors in Windows (error=2,3,...)

Question

Hello,
I had a Java progam that makes calls to external programs (of the type of question 2 in the FAQ), but for which I have no access to the code (it is intended for Unix). I have Java installed including the docs (except search API). My question is:
error=2, error=3, error=193 are IOEXceptions which mean something like file not found, not an executable file, the processe returned an exception, etc. Where can I find a translation of those cryptic numbers in plain English, within the docs?. Searching the Internet is not efficient ... TIA

Just to add some perspective:
Almost all UNIX platforms provide a file called /usr/include/errno.h (or same name in a subdirectory /usr/include/*/*.h ) as part of the baseline OS. It is only about 100 error codes and is based on the UNIX system calls. This file is provided even for those UNIX platforms (like Solaris) that do not provide any form of C compiler with the OS software (you have to pay extra for the compiler, often a lot extra). Its pedigree goes back to the origins of UNIX.
While Microsoft has a web page with their error code info, they do not provide the file is as part of the baseline OS. I agree that Sun could attempt to provide pointers, maybe as part of a FAQ on their web site. Perhaps Sun does not want to get bogged down with the complexities introduced by a major competitor's legacy issues:
ERRNO.H (for the WIN32 version, about 40 codes, for the C Runtime Library)
ERROR.H (DOS error codes, derived from XENIX, OS/2)
WINERROR.H (12,000 line header file all Win32 codes know at that time, using fields � la DEC's VMS, but includes codes of ERROR.H)
I expect that Sun's implementation of System.exec() calls the Win32 API routine CreateProcess and that probably the only codes you will see returned are defined in ERROR.H
