To follow up,
while the link/change I mentioned that got images to display using the
app/assets/ctx/1.0/<...> was working using mvn jetty:run on my
development machine, deploying as a WAR seems to break these links in a
production environment.
So I'm back to square one it seems, is there no simple way to do this?
If so I'm guessing I'll have to manually load the files, into an Asset
or something along those lines?
It doesn't really matter to me if what I have to do is hard or easy, I
just need to know what it is!
As a follow up, I am able to use the File class from java.io to load the
image files from the filesystem, so might that be a starting point for
me to get my desired results?
I also looked at this page
http://tapestry.1045711.n5.nabble.com/T5-Auto-Generated-Picture-Gallery-Intranet-td3298328.html
but the images won't display. I thinking because these files aren't
being served, my local machine can resolve the "file:///<..>" urls to
the image files, but they won't actually display in the page. I'm
thinking this might not be my best solution for a production environment.
Thanks,
Rich

Hi,
Yea, I wasn't expecting TML shorthand, rather some way to load the
proper information in the page class.
I couldn't really see how the ContextAssetFactory would be useful. I
was under the impression internal services shouldn't be used, in fact
trying to Inject it gives an error.
In terms of loading the file as a Resource (required parameter for the
createAsset method), I've had trouble with that as well.
I have a database entity that stores a reference to the image file
(this is the same entity in the grid I mentioned before). When
creating or editing this entity, I tried making a validation check
that the file actually exists in the system.
Resource resc = new ContextResource(cimpl,
"src/main/webapp/layout/images/products/"+link);
if(!resc.exists()){
debug("\nImageLink is to a non-existant file! " +
resc.getPath() + " get file: " + resc.getFile() + " to url: " +
resc.toURL() + "\n\n");
_form.recordError(imageLink
,messages.get("image-link-non-existant"));
return;
}
Even though the files I tried definitely exist (I know because if I
remove the validation I can get some images to show in pages loading
the entity), the condition on !resc.exists() always fails.
I have code elsewhere that uses
Resource resc = new ContextResource(cimpl,
"src/main/webapp/layout/images/products/"+link);
to load .xml files with the beginning to the path "src/main/webapp/.."
that works, so I'm having a hard time understanding why it fails. The
other implementation is in components.reports package, while this one
is in pages.admin package. That wouldn't make a difference on the path
needed for the ContextResource, would it?
I actually got passed the filter issue by doing this:
instead of TML having <img
src="/app/assets/ctx/1.0/layout/images/products/${prod.imageLink}" />
I moved the src text to the page class
<img src="${getImageThumb()}" />
maybe that wasn't even the issue.. So it seems I am able to load the
images alright then.
I could still use some help with the Resource checking. Is that the
best idea for validating the existence of a file in the context
(assuming I get it to work properly)?
Thanks,
Rich

But that would generate the same /app/assets links, just not
hardcoded. This

Hi,
I'm having a hard time figuring out how to dynamically display some
images I have in a sub-path of my webapp/ folder in my Tapestry
application (1.5.0.5).
I have db entities that store the names of files in a folder in
webapp/layout/images/products/, and in a TML page using a grid, I
want to be able to display these images.
The only way I was able to get an image to display was to provide a
path like:
/app/assets/ctx/1.0/layout/images/products/${prod.imageLink}
That gave me problems with my Application filter/dispatcher,
however, as it seemed to regard this is a page access outside the
scope of the user-session context and log out the user.
I'm pretty sure I shouldn't be hardcoding that reference to the
asset from a url anyway, how can I have it load the image through
tapestry like all the other images in the site, like the ones I load
through CSS that do not break the application filter/dispatcher?
I hope I was clear enough as to what my problem is.
Thanks,
Rich
