Re: [Wicket-user] Image upload
I guess the same can be provided for file links. For example, I am writing a demo application using Wicket for an online voting application for a UK broadcaster and one of the outputs is a file which gets emailed out to a user. I also want it to be accessible from a link (at the moment it exists in /var/tmp on my server) so as per the image resource it could just be streamed. It seems a lot of work though to do it like this for a simple file link - is there an easier way in Wicket that you might think of (I'm a newbie at this framework so any suggestions would be helpful) -- View this message in context: http://www.nabble.com/Image-upload-tf1487150.html#a5126218 Sent from the Wicket - User forum at Nabble.com.

Though that will only work when your servlet container is configured

No, you can deliver files from anywhere Java has access to. The example
was copied from production code.

Re: [Wicket-user] Image upload
What I meant is that it only concerns paths in the scope of the servlet context. And the problem with that is that you can't be sure you have access to that and/ or that that's a normal file system (it might be from a zip or jar/war). So you code might work for absolute paths outside the servlet context - I've never tried that - but it's not guaranteed according to the spec.

Re: [Wicket-user] Image upload
Hi Philip,Thanks so much for the sample code and wiki entry...it makes a lot of sense, however, it is a little bit of overkill for the app I built. You gave me a bazooka to take to a gun-fight!Really, what it comes down to is; I need to turn the byte array I'm pulling out of the file system and turn it into an image. The upload I already had one of my devs build was working fine and I'm not sure (for now anyways) we need your full-on image service. I'm googling around to see if I can figure out how to simply turn the byte array into an image I can display on a page...not something I'm familiar with.

Hi Philip,
Thanks so much for the sample code and wiki entry...it makes a

app I built. You gave me a bazooka to take to a gun-fight!
Really, what it comes down to is; I need to turn the byte
array I'm pulling out of the file system and turn it into an
image. The upload I already had one of my devs build was
working fine and I'm not sure (for now anyways) we need your
full-on image service.
I'm googling around to see if I can figure out how to simply
turn the byte array into an image I can display on a
page...not something I'm familiar with. I couldn't gather
from your example how this would be done, either.
Thanks for the help!

Re: [Wicket-user] Image upload
You don't *have* to use the ImageService. You can make the
ImageResource fatter if you need. I documented the ImageService simply
because that's what I have already and I think that using services is
generally a good idea.

The ImageResource uses parameters to determine what image to pass back
to the caller.
I'm not generating thumbnails...my version of this is much, much, much
smaller. I'm uploading images to a pre-defined, static location.
That part works great, no problems there. I'm then pulling them from
that static location to display them.
The thumbnails is only a happy extra. You still need to know what
image. Without thumbnails, you've cut back from two parameters to one.
You need a parameter that tells you which image out of that predefined
location to return.
I know that static path on disk where the images are located and I
know the name ahead of time (looping through a ListItem in a ListView
from EJB3 entities in a List).
How is the id querystring param relevant? Can't I just pass the path
+ img_name.gif into the urlFor() and be done w/ it?

Re: [Wicket-user] Image upload
so what you need is something that maps to some url and when invoked streams the image back to the user.i see two possible ways to do thisone:use a separate servlet to do thistwo:use a wicket shared resource
in both approaches the code will be 90% identicalwhat you need is to somehow tell this servlet or wicket resource which file to stream, this is what you pass in as a parameterie:
www.server.com/myimageservlet?4this can tell the servlet that you want to stream c:\\app\\images\\img4.gifsame goes for the wicket resourceyou have a resource reference which builds the url that will hit the resource ( urlfor(resourcerefence) ), but you still need to tell it which image you want served
so the entire process once you registered a resource and obtained a reference to it goes like thisimg wicket:id=img/String url="" // base resource url

Ahh...I got it workingand yeah it was far easier once you guys showed me how to actually call the image as a resource. I was getting the byte[] all along w/o a problem...it was the display that I wasn't familiar with.
I *really* stripped Philip's example down to the bare metal...but I can *now* see how a lot of that would be useful...so I may go back and do some refactoring now to take advantage of some of the ideas.Anyhow, it looks great and I really appreciate the help Philip Igor!

i see two possible ways to do this
one:
use a separate servlet to do this
public class WeblibServlet extends HttpServlet {
private static final String base =
/WEB-INF/classes/META-INF/admin/weblib;
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
String p = base + request.getPathInfo().replace(.., );
RequestDispatcher d = getServletContext().getRequestDispatcher(p);
if (d != null) {
d.forward(request, response);
}
}
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
doGet(request, response);
}
}

Re: [Wicket-user] Image upload
I definitely don't want to use blobs Where can I find an example of doing what I need using WebDynamicResource? I don't even see this class listed in the 1.2 Javadoc... Where do I start? Thanks!

Re: [Wicket-user] Image upload
WebDynamicResource is new in the latest 1.2 releasesjust a rename of DynamicByteArrayResourcejust make a ResourceState (inner class of DynamicByteArrayResource)and in getDate() you lazy load youre byte array from somewhere johanOn 4/27/06, Vincent Jenks [EMAIL PROTECTED] wrote: I definitely don't want to use blobsWhere can I find an example of doing what I need usingWebDynamicResource?I don't even see this class listed in the 1.2Javadoc...Where do I start?Thanks!

[Wicket-user] image upload
I'm sure this has been asked before but I couldn't find an example. I'm using JBoss 4 and Wicket 1.2RC2...and I'm trying to upload images into a specific folder inside of a deployed .ear project. The folder in the web app would be /ear-name/assets/images However, that folder doesn't exist after I deploy the EAR file, there technically is no folder to upload *to* - unless you count the stuff that's created in /tmp and /workand that's not something that can be hard-coded. How can I get around this? Thanks! --- Using Tomcat but need to do more? Need to support web services, security?

Re: [Wicket-user] image upload
can you upload into the ear's unpacked folder? is that safe, will images still be there after you redeploy?usually you set a dir that you want to use that is outside the webserver, ie d:/assets/myapp/images and you pass that as a config param to your app. -IgorOn 4/26/06, Vincent Jenks [EMAIL PROTECTED] wrote: I'm sure this has been asked before but I couldn't find an example.I'm using JBoss 4 and Wicket 1.2RC2...and I'm trying to upload imagesinto a specific folder inside of a deployed .ear project.The folder in the web app would be /ear-name/assets/imagesHowever, that folder doesn't exist after I deploy the EAR file, theretechnically is no folder to upload *to* - unless you count the stuffthat's created in /tmp and /workand that's not something that can be hard-coded.How can I get around this?Thanks!---Using Tomcat but need to do more?

Re: [Wicket-user] Image upload
you could save those images to a DB or to a working dir on the server.Then have a DynamicByteArrayResource or the 1.2 one: WebDynamicResource to load the image from the location you stored the image.johan On 4/21/06, Steve Knight [EMAIL PROTECTED] wrote: I am creating a form that will allow users to upload image files that will be displayed on other pages.

Re: [Wicket-user] Image upload
I do this and save the files off to a working directory on the server, while the metadata is stored in the database. I didn't know about WebDynamicResource, so I wrote a simple servlet filter to handle it for me.
