How can I display server files to browser with Java Spark - webdav

I have started using Java Spark to with my Java application, running an embedded server, the idea being my software can then be controlled by a browser from a phone/ipad with the server running on Pc/mac ecetera.
I want the user to be able to browse folders on my server from their browser so I was thinking that webdav might be the answer, but how do I do this with java-spark, are there other solutions ?

Seems just using standard Java classes to generate file list and passing it to browser and then using jstree or similar to browse it is the way to go

when i double click on the batch file its opening the text file.But when run above code its not opening any notepad.
it is not showing any exception also.
Please Help
Thanks
This is the wrong way to read a text file from ASP.NET, you need to use System.IO and put files you need to read somewhere where ASP.NET can get at them, eg.. App_data. That said, here is how to do it the wrong way: IIS runs on an invisible virtual window--it's a service. There is a way to get some services to display the UI, I forget how. In any case, you'd have to RDP onto the server, to see such a window after starting the service and goosing it into displaying a UI (this trick might not even work for IIS).
Next, as commenters noted, on IIS, you'll have one set of credentials different from your own (depends on what version of IIS)-- in any case, it will have restricted access and be somewhat sandboxed. If you set up impersonation and windows authentication in the web.config, sometimes you can get your request to run with your credentials.
Next, if the web host runs in medium trust, you might not be able to launch arbitrary apps from the asp.net appdomain.
Finally, the only way this could ever work is if your app is always running locally with casinni (the visual studio development server)-- but in that case, you could simplify things a lot by using a console app instead of asp.net unless you really need the HTML templating, say for output.

How to execute an exe or a file in local machine using a website or html (like clone in windows in github)

These are my requirements
How to open an pdf file which is located in my local machine using html page?
How to execute an exe file which is loacted in my local machine using a website?
This is like what github does when we do clone in windows option.
I need to implement exact same operation . I have a button and when I click that it need to run an application.
Thanks in advance.
You installed GitHub for Windows on your computer. And this installation registered the protocol github-windows: with the GitHub for Windows executable as handler. Nothing special going on here.
The only chance I see is to register your own URL scheme (as you said myapp-pdf: or something like it).
Then you can redirect (or open a new window) to a URL with your custom scheme and the browser should start your application giving you the URL as a command line parameter.
Create custom Url Schema and Map to the application
I just explain some thing I got after your inputs.
As all guys mentioned above, I need to generate a url schema for my application
I need to register the schema and application path to be executed in Windows registry. This need to handle during the installation .
http://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx
This link will show how to add the particular schema in windows registry and we can specify the application to be executed like mailto: for Outlook.
Thanks for SO to provide the details from here.
how do I create my own URL protocol? (e.g. so://...)
Pros
Need to check about the security issues which may occur if we are using this approach.

Loading/Saving Word Documents from Web App (asp.net MVC)

I'm making a web app. Part of it includes the automatic generation of word documents (letters). Those documents need to be opened by the end user, then saved back to the server once they've finished editing.
I tried using webdav for this but the only browser I could actually launch word from (using active-x) was IE. I also found a plugin for firefox, but for Chrome I couldn't find a way that worked.
Next I thought about making the clients map a drive to webdav (or similar), then offering up the files as file://... links, but that only works if the webpage is on the local machine.
Before I resort to ditching word (the clients won't like this) and using CKEditor or TinyMCE, is there another way?
In short, I'd like to have links to a document on the page, which when clicked are opened in word, but the file should stay remote - and then when saving, it's the remote file that gets updated.
I've also looked at Zoho but it could be very expensive for this project, plus I don't think it can be white-labelled and also looks a bit old fashioned, UI wise.
Maybe Sharepoint can do what I need? Haven't looked at that much. Also thought of making a client app to run in the system tray and deal with things.
If there was a decent way of editing Word docs from within the browser with something like CKEditor/TinyMCE and once finished, conversion back to Word format actually worked 100%, that would suffice.
I'm open to totally fresh ideas if anyone has any...
Currently Chrome, Firefox and Safari support MS Office plugin. They can open and save documents directly to server. I have tested this with MS Office 2007 and MS Office 2007 just about a month ago.
Ideally, your users would be able to use Word natively. Is there any chance you could create an Office Add-In that hooks into the BeforeDocumentSave event, looks for some indicator that the file is associated with your application, and save the updated file to your server?
Saving to the server via the Word Add-In would probably need to include some unique identifier (in addition to file name), so you could overwrite the previous version server-side. Then, if you were using something like SignalR, you could trigger a refresh on the web page when the file was saved successfully (assuming they were still on that web page) on the server (via FileSystemWatcher).
Had same problem myself.
I solved it by setting up a webdav share on the server with digest authentication (SabreDAV), and tied it into the users table on my app backend.
In relation to the client end, I solved accessing this by creating a small java applet which uses the java Desktop class (getDesktop().open()) to open the file. You will need to make sure the path is handled right for the client machine type (Windows, OS X or Linux)
You will also need to get your end users to permanently mount or map the webdav share locally.

Run a remote python script from ASP.Net

I have a python script on a linux server that I can SSH into and I want to run the script on the linux server( and pass it parameters entered by the user) and get the output on an ASP.net webpage running on IIS. How would I be able to do that?
Would it be easier if I was running a wamp server?
Edit: The servers are in the same internal intranet.
Probably the best approach is the least coupled one. If you can determine a protocol that you're comfortable with the two (asp/python) talking in, it will go a long way to reducing headaches.
Let's say you pick XML.
Setup the python script to run as a WSGI application with either cherrypy or apache (or whatever). The script formats it's response in XML and passes that to WSGI which returns the XML over HTTP.
On the ASP.NET side of things, whenever you want to "run the script" you simply query the URL with the WebRequest class, then parse the results with LINQ-to-XML (which on a side note is a really cool technology).
Here's where this becomes relevant: Later on if either the ASP.NET implementation or the python implementation changes you don't have to re-code/refactor the other. Later if you realize that the ASP.NET app and some desktop app need to be able to do that, you've standardized on a protocol and implementing it should be easy and well supported.

Flex Write File

I checked in the API, that writing a file is only in Flex Air.
Despite of that, is there still a way in Flex to write a file on the server or on the client machine ?
More concretely, it's because I have a String and I will decode it by mx.utils.Base64Decoder
to a doc. And I need to open it by Word directly on the client side, or write it on the server and return the link to the client for downloading.
Thanks
I'm doing something similar - I have built a custom grid in Flex that contains an additional button on it that allows the user to open the data up in Excel. I've done this by writing a function in PHP on the server which my Flex speaks to. This creates the CSV file on the server and the function passes the link back to the client, which in turn offers the user the chance to open the data up in Excel.
I'm using the Zend technologies to accomplish this - I recommend you take a look; they're extremely good. I used to use Flex Data Services and Java do do this but just recently switched to PHP because development time is cut down drastically as a result.
Hope this helps.
Jamie.
AIR applications run on the users' desktops. They allow you to write to the users' desktops. Nothing stops Flex/AIR applications from communicating to the server, write some files there (using a suitable backend technology) and return a link back to the user.
