A plan to access files outside the context/Tomcat?
I have a need to place and get, image files, to and from a directory outside
of the context and outside of Tomcat.
My plan is this:
Have an upload page to allow user to select local file on client and upload
to server. This is the same tactic as the manager is using with war files.
The folder will have rights set to allow read/write by Tomcat user.
This part, I think, will be staight forward. OK so far??
Next to retrieve the image and serve it back to the client is a little more
involved.
The plan:
Servlet to accept all request for the /context/pics/* .
Servlet reads file from directory and writes it out to the Servlet output
stream.
Am I nuts or is this a feasible plan?
Just need to know if I am going in the right direction and if anyone has any
code snippets of the servlet writes.
As for the file I/O I have that covered I think.
Any/all comments welcome.

Adrian,
Am running in standalone. Currently on 4.1.29 but production will be 5.0.19.
But will keep it in mind. If my app goes public I may need to set up Apache
to do virtual hosting.
Kumar,
I had considered that, but am running on MySQL and wanted to keep the
database as simple as possible(for my own sanity). Might change my mind.
OK, I just did a little reading and this sounds like an idea I can work
with.
So go ahead and send me both if you don't mind. Just in case. I am on Linux.
Thanks for the feed back. Additional comments welcome.
Doug

Sounds like a workable solution. Are you using apache or some other
front-end to Tomcat? If so then you can use an alias to serve up the images
rather than serve them up manually with your servlet. I've done it both
ways in content management systems I've made and letting apache do it saves
a class or two...
Actually you might be able to let Tomcat do it for you if you set up a
connector to listen on port 80. I've never used Tomcat alone so don't have
any experience doing it that way.
