One can definitely spawn Java from C, but every JVM I know of
is a *Windows* application, which mean that it wants *Windows
paths*, not cygwin-style paths. You may find the cygpath
utility useful in scripts run under cygwin, to convert between
different styles of path.

Java, in particular, wants things like its classpath as a
*semicolon*-separate list of *Windows* path names. These
generally require suitable quoting if being used in scripts
or with bash, since bash interprets semicolcon as separating
bash commands, etc.

As for the particular errors, I am personally less familiar
with using cygrunsrv ...
