[Using Sakai] Web page won't open in Sakai

Thu Jul 2 07:04:20 PDT 2009

Hi,

If you're putting this in an iframe, it's not so much what Sakai "likes" but what your browser likes. The File Type is used as the content-type when the file is served. Try text/html.

Sakai makes some inferences based on content type as to whether the content-disposition is set or not, which triggers a download prompt if it's set to attachment.

Regards
Stephen

Hi Steve,

Thanks for getting back. I've interspersed replies.

I had been thinking that Sakai may not like XHTML, but when I saw this I realized it recognizes it. The only other thing along these lines is that Sakai can handle XHTML but prefers pages with "html" as their extension instead of "xhtrml."
Tidy and friendly markup can still be written as html and you can still use the XHTML Strict DTD. 

Also, what version of Sakai (scroll right to the bottom and have a look in the footer, assuming that has been set correctly)
It's 2.5.4.

cheers,
Steve

Hi,

I'm having a problem opening a web page in Sakai. I used the method described on Putting Sakai to Work ( http://www.packtpub.com/article/putting-sakai-to-work ) under "Customize the Home Page." However, when I click on the tab for the page, instead of  displaying it Firefox (both versions 3.0 and 3.5) pops open a dialog window asking whether to save the file or to open it in Firefox. If I open it in Firefox its starts a new tab but the file does not display properly, apparently since it left its support files on the Sakai server. Can anyone explain why this may be happening or suggest ways to correct Sakai's behavior?

Thanks.

Additional BackgroundThe page works fine when I load it on my local system, so the problem is the result of its interaction with Sakai.

The page sits in a subdirectory of the worksite's Resources. The subdirectory is called "Web" and itself contains five subdirectories: boilerplate (for standardized page content), code (for JavaScripts and other code), images (for graphics), styles (for css), and templates (for web page templates). 

The page's Doctype is DTD XHTML 1.0 Strict, and its file type (extension) is xhtml.

In its <Head> section, the page loads five JavaScript libraries with paths in the form of 'src="code/FILENAME.js"' (uppercase denotes variable content):
Boutell.com's client-side include ( http://www.boutell.com/newfaq/creating/include.html. ) JavaScript for including boilerplate on the web page.
The b9j JavaScript toolkit ( http://appengine.bravo9.com/b9j/documentation/b9j.html ) (for working with paths to make the page and its children portable)
jQuery  ( http://jquery.com/ )(for the drop shadow plugin now and for customizing page behaviors later)
The jQuery drop shadow plugin ( http://plugins.jquery.com/project/DropShadow )(for cosmetic purposes)
Simon Willison's JavaScript loading utilities ( http://www.webreference.com/programming/javascript/onloads/ ) (to coordinate loading functions)
In addition, the page has some JavaScript embedded in the page. This script does a few things:
Create a new "global" object that will hold various global variables; it also initializes a few of these
Include one piece of boilerplate html (a standard page footer)
Add some code to the drop shadow plugin; the code rescales the drop shadows when the current window is resized; eventually, this code will be added to the plugin.
Applies the dropshadow method to add drop shadows to all images on the page with class="solidShadow"
Assigns two functions (init and resized) as methods to the window object (i.e., window.onload = init; and window.resize = resized;)
The last thing in the <Head> section is a <link> statement loading a css file. The link refers to 'src="styles/FILENAME.css" media="screen".' The css code uses a few unusual (but way cool) techniques. See:
Perfect fluid width layout ( http://css-tricks.com/the-perfect-fluid-width-layout/ )
100% fluid full main column layout ( http://layouts.ironmyers.com/ )
Scalable figures with captions ( http://rjohara.net/server/css-figures-captions/ )
The <Body> section uses a liquid design ( http://www.digital-web.com/articles/liquid_web_design/ ). It uses lots of <div> and <span> elements with class and id selectors.

Other than this, the page is not unusual (unless Sakai has problems with JavaScript and/or CSS).
