I posted this question to the Geronimo users mailing list as well, but I
thought maybe someone here could help me out.

I'm sending an image to my servlet using a post command. This works
fine. I can save the image to "/tmp/image.png" without any trouble. The
problem is that I can't get to it from the Geronimo server. I'm not
running apache, just Geronimo. It serves everything. I don't think
there is a directory I can just drop my image into to give it a URL. I'm
not sure how to save data in Geronimo so that it can be served using an
image tag in an HTML page.

So where do I put the image and what would its URL be?

I think you have to design the "get" for the image too, not just the
put. In other words, put the image somewhere (/tmp is probably ok for
now) and then write a JSP to fetch all images from /tmp, code them up to
look nice as links, the spit the resulting HTML out to the user. Name
this JSP "MyImages" and place it directly off the webapp root. Then you
can use the URL "example.com/appname/MyImages" to get that file.
Eventually "/tmp" has to be a configurable parameter so that you can set
it to whatever is correct for the local file system.

Alternately I guess you can just dump the files themselves in some
subdir. Is that what you are asking? I'd try making a directory on the
document root, .../images or something, and see if you can write to
that. Use "images" with no slash in front I think. Maybe that's what
you really mean.
