IMG SRC URL in iframe.
Hi,
I would like to use an iframe on my page that contains IMG tags. I would
like the IMG tag SRC to point back to the server to load up the image.
What would be the best way to construct the URLs in Wicket?
Many thanks for any advice, Graeme.

Ernesto,
I really appreciate your help - thanks for the information. I will try to
take a look at it tonight!
Cheers, Graeme.

Hi Graeme,
Yes, it is the approach I would follow... I'm not 100% sure about all
the details (e.g maybe the URL is not exactly /images/xxx), but I'm sure
that approach that will work. As said I used a similar approach
sometime ago for displaying a documents inside an iframe: I mounted a
dynamic resource that was generating the content based on some ID and
the iframe src just contained the URL of the resource. Your use case is
a bit different but it will also work. Another possibility is to have on
the same page , where the "HTML" is going to be displayed, a component
implementing IResourceListener and have that component generate the
images...
Right now I'm very busy with other pressing issues at work but if I
find time I'll try to build a small example illustrating this.
Best,
Ernesto

Re: IMG SRC URL in iframe.
Posted by Graeme Knight <gr...@gmail.com>.
Hi, thank you - this is invaluable information.
So basically what you are suggesting is something like:
1) Read the HTML content (this will be set on the innerHTML of the iframe).
2) Parse the content to find the each IMG SRC CID - replace this CID with a
URL to /images/xxx.
3) Set the HTML into the iframe.
4) On rendering the iframe IMG SRC will point back at the server that will
serve up the image, essentially.
Appreciate your help!
Graeme.

...something like:
private static String ID = "MyImages";
@Override
protected void init() {
super.init();
getSharedResources().add(ID, new MyDynamicImageResource());
mountSharedResource("/images", ID);
....
}
On you WebApplication class... Then ask back to the server for /images/xxx
and your MyDynamicImageResource will pick up the xxx and stream back that
xxx image... MyDynamicImageResource should implement some of the extensions
of DynamicImageResource... Long time ago I implemented something like that
but I don not have that code at hand anymore... But it shouldn't be that
difficult to get that working.
I have seen this

example
but don't if it will be of any help to you...

Re: IMG SRC URL in iframe.
Posted by Graeme Knight <gr...@gmail.com>.
Hi Ernesto,
I think that is exactly what I am after - just not certain how this
implementation works in Wicket. It was real easy with Tapestry as all I did
was get hold of the URL, append a path to the image, and replace the CID in
the HTML with the image URL.
Are there any examples of this sort of functionality?
Many thanks, Graeme.

Why not mount a resource that is servicing back images based of the CID?

Re: IMG SRC URL in iframe.
Posted by Graeme Knight <gr...@gmail.com>.
Oh,
My use case is this:
1) Load up HTML email content. This content has CIDs which need to be
resolved to URLs.
2) I will put the HTML content into the iframe using some Javascript to
manipulate the innerHTML.
3) Before I do step 2 I need to convert the CID to a URL that points to an
image file on the server.
Its this URL construction that concerns me.
Many thanks for any suggestions, Graeme.
