Re: Preview of an Image and text
Since we are on this topic, any ideas on how to build images from a
webpage which is downloaded automatically into a database or a file
system. Eg would be google desktop style, where a thumbnail appears of a
html page beside a search item.
Regards,
Amin
Just carry the path of the file, not the image itself. When you submit
the form you can get at that information (I believe, if not just grab it
via JavaScript on the form submission and stick it in a hidden field).
Then, when yout next JSP executes, you have the path to the file and you
construct the img path:
img src=%=file://+myForm.getPathToImageUserSelected()$
Something like that. The basic idea is that the JSP you send back as a
result of the form submission is displaying the image from the user's
PC, not your server. You just need to append the file:// part of the
image's URI at some point.

Works on IE, can't say whether it does on anything else. Of course,
this will only work if you have enough information to construct the
complete preview on the client at that point, but you could
alternatively submit the form, then in the reply construct the file://
reference to the image as I've done above. That would probably give you
the best of both worlds, and also remove any cross-browser concerns.
But, if you can do it without touching the server, so much the better I
figure.

Re: Preview of an Image and text
Hmm, that's one I've never tried... Just to be sure I understand, you
basically want to be able to render a page and then produce an image of
it, and store that either to a database or file system? If so, that's
certainly an interesting request...
I can't vouch for this program, I just looked at it for the first time,
but check out HTTP2IMmageat www.sysimage.com. It's interesting because
it has a command-line component. Assuming you are on Windows of course,
although I'm sure similar programs can be found for your favorite *nix
variant if you need it, this might be an answer...
You could write the results of the JSP out to a file (not sure the best
way to do this), then shell out to this program to generate the image,
then do whatever you want with it. I'm oversimplifying things of
course, but the idea is what's important.
Alternatively, assuming still that you are on Windows, you could always
make use of IE itself... You'd have to look around, but one of the
features I remember is being able to ask the render engine to render to
an off-screen buffer, and you should have little difficulty getting a
proper image from that, assuming you made it that far :) Me personally,
I'd go with something like HTTP2IMmage... My Windows-specific
programming these days is limited to PocketPC development, not sure I'd
want to get into anything too deep on the desktop these days.

Re: Preview of an Image and text
;
document.frm.imageName.src = Img.src;
}
The function is a java script which is called when the jsp page loads. ie
call getURLString() when this page loads and as shown below.
BODY bgColor=#ff onLoad=getURLString()
There should be a hidden variable of T1 whose value is the path of the image
(eg c:\\image.jpg) in ur jsp page as shown below.
input type=hidden name=T1 size=39 value=imagePath
Last ur jsp file should contain a image tag for display of image.
img border=0 name =imageName src=
The value of the hidden name (imagePath) should be passed from the java
action file.

Re: Preview of an Image and text
Works good with firefox as well , seems like a damned good simple
solution to me.
Hey did you see Brady Hegberg's post for dynamic dropdown list's, I
reckon you'll like it as well,
also cross platform.
