GraphicImage Question
Basically I'm building an ecommerce site using MyFaces. I have over a years
experience with it, though I've come across a problem I have never
encountered before.
For this site the user can upload images of the item they are selling.
Except I am having some problems with storing this and displaying the info
on screen. I was going to save the image to a location locally
("C:\images\uniqueId") and display this with <h:graphicImage> but it does
seem to like reading from this location. I am running on a windows machine
but noticed when supplying the string for the location of an icon saved
within the application the directory would be /Deploy Name/image.
How can I use the graphicImage tag to read from outside it's JBoss
deployment? Or would it be better saving somewhere else when a user uploads
an image?
Any help would be much appreciated as I have no experience with uploading
and saving of images on this form of web application. I would prefer to
save a link in the database and display this way if possible.
Thanks
Michael.

Then, use a PhaseListener to retrieve image from a file and output the content.
It is the same, but instead of reading from a database resultset, you
should read from a file, as in any Java application.
Here there is an example for a phase listener that send a image:

Thanks for the feedback.
The model for the application was created using EJBs previously with the
image variable used as a string in the database. I planned to build the
front end without changing the model as a MVC proof.
Thanks

Michael,
Here's another option you can try that I've used successfully. Store images
in a database and create a PhaseListener to retrieve image and output the
content.

Oh yeah of course. Can't believe I got stuck on this problem without
thinking of it as being run through a remote browser. I'll fix this by
making an image object reference in the code running on the server, rather
than in the web page.
Thanks, I'll try using my brain next time.

Re: [Solved] GraphicImage Question
Posted by Veit Guna <ve...@gmx.de>.
Did I miss something? You're talking about an webapp right? That means,
a user from location A calls your application at location B (A and B are
on different machines). So when the user uploads the image, it will be
stored on B, right? So you (browser on A)can't access that file through
an absolute (local) path! I think "value" takes an URL that the browser
has to resolve. When this is C: it can't be reached on the server - it
will try to find it on the local (A) machine. Just look into the source
of your page, it will point to something like "C:...". It should be
something like "http://youtserver/webapp/file" or "/webapp/file".
But maybe I didn't get you right...

Re: [Solved] GraphicImage Question
Posted by m1380103 <m1...@qub.ac.uk>.
See that's why my problem came about.
I wanted to save on the local folder thinking it would be simple to use
graphicimage with either c:\\images\\uniqueId or c:\images or c:/images but
I haven't found any way to work yet. I think it might be helped if I pass
the image directory location from the java class. The strange thing I
noticed from the page source after JSF had rendered was that the windows \
was not shown in the source. That's why I thought it might be related to
the graphicImage tag's use of the \ symbol, even when \\ was used.
I can't seem to find an example anywhere online where the tag is used to
read from outside the deployment directory, maybe the original idea for
writing a renderer so the directory for the images can be set is the only
way to go about this.

Perhaps:
<graphicImage value="C:\\images\\uniqueId">
?

Re: [Solved] GraphicImage Question

Thanks for the quick reply,
I have spent some time looking over the JSF examples, including the
sandboxes graphicDynamicImage. My problem really lies in displaying an
image from outside the deployment directory. There is no dynamic action
needed in my application so I thought the standard graphicImage would do,
just not sure why my <graphicImage value="C:\images\uniqueId"> wouldn't
work.
I will look into extending the imagerenderer to read images from a directory
on the hard drive, though if anyone knows a simple example of using the
graphicImage and reading from a standard windows folder, the help would be
much appreciated.
Thanks
Michael.

Re: GraphicImage Question
Posted by Veit Guna <ve...@gmx.de>.
Hi.
Take a look at the sandbox graphicDynamicImage. There you can write your
own ImageRenderer and you're free where you read the images from.
In my webapp uploaded files go to a separate directory outside the
deployment directory of tomcat. The ImageRenderer reads files from there
and displays them to the user.
Perhaps it helps.
regards,
Veit
