I have some pdf files located on a http server:
Like:
http://domain.com/files/file1.pdf
http://domain.com/files/file1.pdf
http://domain.com/files/file1.pdf
I need to display these files on a mobile application using java me.
I tried to display them by opening Google Docs Viewer with platformRequest. However it seems Google Docs Viewer uses ajax and many mobile browsers does not support it.
Is there an alternative for "Google Docs Viewer" for mobile devices ? Or is there a better solution for this problem ?
Unless you have something can interpret the PDF on the phone, you may need to convert the PDF to images on the server for display purposes.

Studying the possibility to achieve the following:
We have a CMS that from time to time posts to a web hook a media URL (video) (public internet hosted)
This web hook post we would like to post directly to a ChromeCast which is plugged in to a TV
Questions:
1. Can a web server like nodeJS be installed on a chrome cast?
2. Is it possible to use for example DynamicDNS to link the Chromecast to a domain name so the post from the web hook can be made?
ChromeCast has a sender API which allows you to "send" content to a specific Chromecast. Right now, the sender API works on Android, IOS and Chrome OS. You can read more about it here: https://developers.google.com/cast/docs/sender_apps.
And, here's how a receiver application that would receive your content on the ChromeCast would work: https://developers.google.com/cast/docs/receiver_apps or if you're content is a standard type, then you can use a prebuilt receiver application without building your own.
To answer your specific questions:
Can a web server like nodeJS be installed on a chrome cast?
No, not without enormous hacking and development yourself to basically take over the hardware somehow and get your own stuff to run on it.
Is it possible to use for example DynamicDNS to link the Chromecast to
a domain name so the post from the web hook can be made?
Not that I know of.
The chromecast has an android like google chrome operating system. It is possible to root it, but you will not be able to (to my knowledge) get a server on it. I would suggest taking a look at the Raspberry Pi. You should be able to run a slim server on it. After you get that set up it might be feasible to pass command line commands to chrome or another web browser to display the data you like. A browser is not necessary, but I'm not sure if you know of any other way to display the media.
A different approach would be to have a server anywhere (could be in your home) and have something like the raspberry pi (any computer for displaying the content) connect to a webpage hosted with that server. Using websockets something like socket.io, you could set it up so that the server could send messages (url of video) to the browser session you have open. The javascript of your webpage would then use that message to open that url.
I have a Mobile Web app (for iphone) based on the Mobile controls of the Xpages extension library.
In the app the user can search for pdf and other files in the nsf files.
When the user clicks on a a filename in a view , I calculate the link like : servername/nsffilename.nsf/O/id/$FILE/filename
This opens the correct pdf file, but the user then leaves the app.
I would like to stay in the app.
I tried it with iFrames, which works fine in some browsers (IE), but not on the iphone (it only displays the first page , no way for scrolling in the pdf, no way to save the pdf file)
I also tried the download control ; but here also the user is leaving the webapp on the iphone
For an image we have a image placeholder , is something similar possible for pdf files ? a pdf placeholder ?
No, this is standard mobile web app behaviour, nothing to do with XPages. By defalt the iphone pdf viewer registers its self to handle those file types. As you have mentioned an iFrame would work to display it (wit issues) but there is no in built XPage control to hande this.
Is there a browser plugin or an extension that allows the user to view .doc files in browser?
I need to embed in my application, a document viewer. So far, I tried using services like google docs, but this solution doesn't work for our application, because of some security problems.
Do you know about the Office Web Apps? Microsoft developed something similar to Google Docs and you can use the Word Web Application to view Word files. It will pretty much display anything - a lot of editing functions from the offline version are not available though.
If you are just looking for a viewer search for "Word ActiveX Viewer" and you will find plenty (commercial) viewers.
To have IE open the .doc within the browser and not in a separate winword.exe, you need to define the association at client end.
As .doc file is an external resource to HTML, it would download the file into its temp, and then attempt to launch it. It would launch it using the default program that it is associated with.
To control this behavior, please have a look at:
http://www.shaunakelly.com/word/sharing/opendocinie.html
I thought Internet Explorer + Microsoft Office used to do this by default?
I can for sure tell you that other than converting the doc to html you won't get a cross-browser, cross-platform solution.
Since you are saying it's for viewing only, that would seem like the way to go.
I have a wmv video hosted in SharePoint. I've created a Content Editor web part with a bit of custom content and I've placed a simple link to the video Click to view.
There is really nothing special going on here. Some users can click on the link and the video opens in their default video player. Other users see a range of different errors/prompts. Some users are prompted for their network credentials and others receive a generic "Internet Explorer cannot display the webpage.
The same problems occur if I create a generic HTML web page (outside of SharePoint) and have users try to launch the video.
I am trying to avoid embedding the video in the HTML and just have users link directly to the video itself.
Has anyone encountered this issue and do you have any suggestions for making this work?
This appears to be a combination of browser issues and file security.
People are being asked for their network credentials because the file itself is not "public"; it requires authentication to be read, or appears to do so from your description. Different browsers will display different messages when attempting to authenticate for the file.
Additionally, the default player for a browser may not be set or the browser may not allow passoff to third party programs, both of which will generate different messages for different browsers. This will always be an issue for hot-linked videos, and there's nothing you can do about it except use some guaranteed playback platform that all consuming browsers must have installed, such as Flash or Silverlight. That comes with issues all on its own, but such is the nature of the online world.
Is there any good browser based WebDAV client? If not, is it possible to make one?
Look at the AjaxFileBrowser from ITHit. Pretty slick, and has FireFox & Chrome PUT support for uploading. IE, drag-and-drop from your desktop to the browser. They have a fully functional demo site up at http://www.ajaxbrowser.com.
There's a plugin for Firefox which handles WebDAV.
Webfolders is a firefox extension that gives you the ability to view the contents of WebDAV
servers in the browser and use the full functionality of the WebDAV protocol.
Depends on what you expect the client to do, and whether you're looking for a cross-browser "web application", or a browser extension.
The main issue with doing this in a "web application" (as opposed to a browser extension) is (1) the lack of binary data support in Javascript, and (2) the lack of access to the local file system (which of course is a security feature).
There is webdav-js which can be enabled as a bookmarklet or served by the WebDAV server itself as an HTML page.
It supports the regular listing of files and directories, file upload, directory creation, renaming, as well as in-page display of images and other media.
If by browser based you mean that it runs in html (ie you don't want your users to install a plugin) then the answer is partly yes and mostly no.
Partly yes, because I have built and used one. It uses the jquery jtree plugin to display folders, and selecting a folder node populates a file list in the right hand panel. Panels are done with another jquery plugin, and the file list is made dynamic with the jquery datatables plugin.
But I think for you the answer is probably "no". Thats because for the browser to use webdav is must user webdav "methods" like PROPFIND and MKCOL. These methods just arent supported in most browsers, so your javascript can't use them directly. I have a server-side mapping in my webdav server project which allows my javascript to use normal GET and POST methods, and these requests are transformed on the server to webdav methods.
I said "probably no" for you since this serve side mapping isnt standard, its a part of milton. But if you happen to use milton, or you can use milton, then its all good.
Try SMEStorage.com. They turn any WebDav back-end into a personal cloud file solution. As well as a rich browser desktop and mobile client, there are clients for Mac,Windows, Linux and Mobile clients for Android, iOS, Windows Phone, and BlackBerry.
