  • Exposing BL as WCF service

    - by Oren Schwartz
    I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? if so, why ? Do you know anyone who had a similar experience ?

  • Recommended programming language for linux server management and web ui integration

    - by Brendan Martens
    I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects that already integrate management of many systems into a single cohesive web ui, except Landscape (not free,) Ebox (ebox control center not free) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo. Also, only manages one system.) Thanks for any ideas! Update: I am not looking to reinvent the wheel of systems management, I just want to "glue" many preexisting and excellent tools together where possible and appropriate; this is why I wonder about what languages can interact well with pre-existing command line tools, while making them manageable with a web ui.

  • ASP.NET Page Caching in a Web Farm

    - by Achilles
    We have a small web farm(2 servers) balanced by the built in network load balancer in Windows 2003. We have a few pages that use page caching. My question is: Is it possible that that a given user could cause a page to be cached and another user see that content? Here is the page directive for the page in question: <%@ OutputCache Duration="1" NoStore="true" VaryByParam="none" %> The reason the duration is set to "1" is to ensure that the page isn't cached any longer than 1 second because of transactions that actions on the page can trigger.

    - by Robert Koritnik
    I would like to know what kind of applications are suitable to be developed on top of Sharepoint 2010 and which should not be built on to of it. So when to embrace/avoid Sharepoint 2010 as a development platform for new web applications. I'm an Asp.net MVC (former web forms) developer and would like to know if usual multi-page semi complex web applications (intra/extra-net) should be built on top of Sharepoint 2010 and why (if yes or if no).

  • Ruby on Rails - Static page as start page

    - by meetraghu28
    Hello! I am developing an app in RoR which has static and dynamic parts. The static portion is placed in the public/ folder of the app. Now if i have an index.html in my public folder then i will not be able to use the routes configured in my routes.rb The default configurations like map.connect /:controller/:action will not be usable if i have an index.html. So i removed the index html. Now i have a static page startpage.html in my public/ folder which has to be the starting page of the app. And the i have links in it for other static/dynamic pages. The RoR app is hosted in apache and i tried to configure the Virtual Host configuration by adding the DirectoryIndex param so that when ever a request comes for the site it will direct it to the startpage.html but still it takes me to the default controller that i have specified in routes.rb with map.root I dont want to add a dummy controller and action and create a view which has the startpage and configure routes.rb to use it as the root. What i am looking to do here is Basically startpage.html should be my first page in the app served as a static page from the public/ folder. This will then have links to other pages and controllers/actions Here i am not able to apache to redirect to the html page instead of passing on the control to rails application. Directory listing is also enabled by using Options Indexes but still no change. Any pointers anyone?

  • iPhone Web Application + zoom in zoom out issue

    - by pratik
    Hello, I am developing a web application for iPhone safari browser. There is one strange scenario: A web page is loaded. User can zoom out that web page to see the contents in zoomed out manner. There is one button in the web page. Click of this button will hide one of the 'div' in same page and another 'div' of that same page will be visible. Problem, is that suppose the user has zoomed out the web page to see the contacts in zoomed out manner. Now, user clicks the button (the page is zoomed out only), the next 'div' which is get visible is also disaplayed in zoomed out manner. What is want to do is that even if user has zoomed out the page and he clicks on the button, the next 'div' which get visible should have the display as zoomed in only.

  • Showing Dynamic Content within a Facebook Page

    - by Jay
    Hi all, I need to have some content displayed in a Facebook Page (I believe these are also referred to as Business Pages?). However, some of these content will be dynamic. What I mean by that is, some of the content will be taken from an existing web application. I've looked into using Static FBML (which allows us to have tabs in the profile page with FBML in it). These no longer allow iframes. Does work in this instance (as I've not been able to get it to work either). Are there any other tags which can be used for this purpose? In short, is there a way to obtain data from an external source and display those content within a Facebook Page (Tab)? Thank you very much in advance for any light that you can shed on this issue. Cheers~

  • Building Asp.net Page code behind correctly

    - by Hagai
    Hi everyone, I need some guidelines about building the code behind of my pages correctly. I mean, I'm building in asp.net for a year now, and mostly using the Page_Load event. (and ofcourse "event handling" the events triggered by the user's actions). I know about the page life cycle and the order of events that happens when a page is requested etc.. . Is it normal that, generally, in a data-driven page, for example, I'm not using any of the "pre_render", "page_unload", "pre_init" etc.. event handlers? or am I missing something here? any guidelines would help me a lot, including links or whatever you think that would instruct me well. thanks.

  • Providing a public Web-Hosting service on MS Windows - advice and resources

    - by crgnz
    Are there any resources offering advice on how to setup a microsoft based web-hosting service? I currently offer LAMP hosting with cPanel, but there is some demand for IIS & SQL Server. As far as I can tell MS Windows Web Server 2008 R2 edition allows unlimited IIS connections. And a per-processor license for MS SQL Server Web Edition 2008 also permits unlimited connections. Where I am falling down is that I can't figure out how to get "unlimited" Active Directory users. I can't use 2008R2 Web Server edition for AD, so I will need the 2008R2 standard edition, I think. Does Microsoft have a provision for using AD in an ISP scenario? I am looking at using the cPanel Enkompas system to manage the Windows software, and Enkompas requires AD for user authentication. Any advice would be greatly appreciated!

  • What web server should I use if I want to run Java code behind?

    - by Boaz
    At the moment, I have lot's of Java which does all kind of nifty stuff and I'm happy with it. The code is command line driven which have been great so far, but I recently decided I want to make the functionality available through web-services. Since my is complex and I'm happy with the way it's written , I don't want go through the pain of porting it to other languages. So I set out on a google journey to find out what web servers exist (on a Linux machine, though it's interesting to hear the answer without that limitation). From what I could find, it seems that there are two viable options: Apache Tomcat and Sun Java Server. What are the reason to choose one on top of the other? what are the strength of each and what are the weaknesses? Or, perhaps, there is a third one which is much easier, flexible and less cumbersome. Anyone?

  • Does <httpRedirect> in web.config work in a mono setup? Or is it IIS7 specific?

    - by Crystal
    We had some content restructure recently and I'd like to put in some redirect rules into web.config so bookmarks to the old pages can get routed to their new locations/pages. I tried using this approach: <location path="~/product/productA.aspx"> <system.webServer> <httpRedirect enabled="true" destination="~/product/category/productA.aspx" exactDestination="false" childOnly="true" httpResponseStatus="Permanent" /> </system.webServer> </location> But all I'm getting when I go to "http://www.oursite.com/product/productA.aspx" is our http 404 page. Am I doing something wrong, or is the httpRedirect tag in web.config not supported in mono? worked, but not ideal for what we want to achieve. Thank you :)

  • Web application and remote storage of files

    - by Matt
    Hi have a web application that can store lots and lots of files on the server. i.e. users upload data to it. The files are stored below a particular storage path. The web host will be an IBM xseries 345. However, the disks are really expensive so we would like to put the files onto a less expensive server. Now here is the question. Should I use an NFS mount on the IBM server of a path on the storage server? Or should I write some scripts to upload the files to the storage server instead. Both the storage server and the web host are on the same network. Only the web server is visible to the world. Is NFS performance suitable for an expected low to moderately loaded server?

  • Set Property Value on Master Page from Content Page

    - by Merk
    Hello, I tried following the advice posted here: http://stackoverflow.com/questions/1071920/set-property-value-on-master-page-from-content-page. Specifically the last post about creating a class. However, visual studio keeps giving me an error on my default.aspx.cs page when i try to set the value: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : BasePage { protected override int NavHighlight { get { return new{0} ; } } protected void Page_Load(object sender, EventArgs e) { } } It throws an error on new, the error being: cannot inplicity convert anonymoustype#1 to int Can someone tell me what i might have done wrong here? Here's what my class looks like: using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// Summary description for BasePage /// </summary> public abstract class BasePage : System.Web.UI.Page { protected abstract int NavHighlight { get; } protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (this.Master != null) { //value assignment } } public BasePage() { // // TODO: Add constructor logic here // } } Thanks.

  • Reasonable Location to Install Web Service on Server

    - by Mr. Disappointment
    Firstly, I'm a software developer and not qualified as any kind of system or server expert so I'm looking for advice in order to help me prevent faults on our server. I've written a modular system to carry out certain tasks for us autonomously to prevent us from writing the same old code over and over again. This consists of a Windows Service (.NET), a Web Service (WCF), a shared Class Library, and a Database which will run on a Windows Server 2003. The problem comes, for me, in deployment. Specifically the web service - naturally the local service (and required shared library) are persisted (by default and convention) in the Program Files folder, but storing the web service here just seems absurd to me (even though we'd lock it down to appropriate use only). Should the files be stored some place else all together? Or split them up and store the web service elsewhere?
