Cygwin & Tomcat 3.21.

[Randall R Schulz]

Steve,

Hi. Me again.

OK. This is a good place for these questions.


Cygwin is a POSIX emulation environment for Windows, as you probably 
know. Part of that emulation is the use of POSIX-style path names. This 
is one of the places where there exist rough edges or visible seams 
(choose your metaphor) and to bridge the gap, a utility called 
"cygpath" is included in Cygwin. It performs various conversions on 
individual directory or file names as well as on PATH-like (including 
CLASSPATH) variables.

You'll probably need to use this if you want to make a stock Unix shell 
script work under Cygwin.

Notice the echoed CLASSPATH in your diagnostic output. The path element 
separators are colons. This is the Unix way. Under windows, the path 
element separators must be semicolons (because the Windows drive letter 
syntax uses the colon and that cannot be overridden or replaced). It's 
not clear to me where this problem originates. It's probably an error 
in how you set CLASSPATH in the first place.

The way I prefer to address these issues is to wrap all native 
(Windows-native, that is) tools I want to invoke from Cygwin in a 
generic wrapper that examines all the arguments and, as necessary, 
environment variables (*) and transforms them. The advantage of this 
approach is that if you have scripts that must work on both Unix (or a 
Unix work-alike such as Linux) and under Cygwin, you need not maintain 
two versions or incorporate all sorts of messy (and conditional) 
cygpath applications you simple set your PATH to pick up these generic 
Cygwin -> Windows scripts (which are all just links to the generic script).

I have developed several tools to facilitate this sort of thing. I 
cannot support them, but if you'd like me to heave them over the wall, 
just say so.
