Launch .exe file from a Jar via Java WebStart

[oziris]

Hi!

Does anyone already succeed in running an executable file from a Jar,
or know how to? The final aim is to perform that via Java Webstart -
which needs all application files be in a Jar file.

The only derived way I find consists in copying the file under the
local disk (via InputStream and OutputStream) and running it from this
location.

Even you don't know the precise answer, don't hesitate still and all to
post the minor birth of ideas you could have.

Thank you.

Your biggest problem is finding some free space to put it in.

All you do is read it as stream of raw bytes and copy it to disk. See
http://mindprod.com/products1.html#FILETRANSFER
for sample code to copy the file a chunk at a time. If the exe is not
that big, you can do read it into RAM and one i/o and write it in one
to disk.

Then use exec. See http://mindprod.com/jgloss/exec.html

I wish there were some easy way to find some permanent disk space with
JAWS to keep such a file, where it would be safe, and yet would be
deleted on uninstall. Ditto it would be nice to easily allocate
yourself a temporary directory.


Sun goofed in writing its temp file method. The files have nothing
distinguishing for scavengers to find them later for deletion if
something goes wrong with autodelete.

When you request a temporary file, you can specify a prefix and a
suffix. This should be enough for whatever scavengers you are referring to.
