The reason you are getting the problem is that by making the executable
"latex", you are *not* using the cmd.exe (or command.exe) shell to launch
the application (which knows about the PATH environment variable), you are
launching the application itself. So as far as the JVM is concerned, its
going to try an launch your application directly, assuming the system knows
where it is. Since "latex" is not in one of the (effectively) hard coded
directories the OS knows to look in, it can't create an instance of the
"latex" application. If you do something like
<apply executable="cmd.exe" depends="init">
<arg value="-c latex" />
... same as before
</apply>
that should get you around the problem. This way, you are running an
instance of the Windows shell, which does understand the PATH environment
variable, and so should be able to find the latex executable.
You know, we see this issue often enough this should be a FAQ entry...
