(3/15/2010) Hi
I am trying to test web services using axis2-1.5.1 (latest version) alone without Tomcat.
Is it possible? If so, can someone point me how to do that?
Appreciate your time and help.
You need to have a web server at any way to test a web application. If you want to ease the development, testing and mocking, consider using an embedded server like Eclipse Jetty. You can configure/execute it programmatically.

I have simple web application built on html5 and RoR. It is simple application where user records his voice(html5 web audio) and then it is saved locally. Application won't be hosted on server instead it would be hosted on individual user machine. I need to develop some portable package like exe which will be run on Windows and Mac.
Is this possible? If yes, then what are the ways to achieve it?
You might find some useful info here
Here are some more recent tools
I am looking to develop some web app for my Android device. Found Sencha and think it might be a good tool to try out.
I suppose I would need to find a web server to host the Sencha app to run the app? What kind of web server is needed? I suppose one that able to run HTML5, CSS, Javascript is enough?
Can anybody recommend one (free one)?
Thanks.

Thanks for the answers to the above post. I am new to this stuff, so got some more follow-up and somewhat related questions:
1) I read from the Sencha site that the app can be developed locally using things like XAMPP installed on local Windows PC. Question -- Why need this local host when I can just use an external Web Host?
2) It was also mentioned that for Windows may not need XAMPP if Window's Internet Information Server (IIS) is already running. How do I know if my computer is running this and so don't need to install another local server? (I asking this because I had installed an XAMPP before on another computer and things got quite messed up and so I want to avoid doing it if possible).
3) Once I got a web host, to have an app running, I would just have to have the JS files in the web host together with the Sencha framework right? If so, then I don't understand what is meant by "Build" in the Sencha documentation.
Thanks.
Sencha Touch is a client side framework, therefore there are no server side requirements. That said, any web host should do.
However, I'll go ahead an make a recommendation... a LAMP stack (Linux, Apache, PHP, MySql) will work the best. Of course you can substitute any of the stack for something of your favor, this setup seems to be the most favorable. Some of my colleagues utilize Ruby/RoR instead of PHP, so as you can see it is quite flexible in terms of environment.
When searching for a hosting provider, do your research and select something that fits with your budget but still gives you the best bang for your buck. Be sure to ask them questions!
Tip: Make sure you have access to your web server's configuration file so you can add mime_types and make other mobile oriented tweaks if needed.
First you must know that HTML5, CSS and Javascript are all front end stuff that do not count when you talk about Hosting. These are taken care of by the client agent (browser).
What really matters is your server side language: PHP, Python(Django), Ruby, etc.
So it mainly doesn't matter which framework, as much as which language that framework use.
This is a generic answer that will help you decide not only in terms of Sencha but for any other framework.
Take for instance WordPress. It uses PHP and MySQL, so first I look if my Web host supports Mysql and PHP and in general this would be enough to know that I can use if for my WordPress site.
And by the way, most Web host companies allow you to ask them questions before buying. So go ahead and question them about anything that concerns your requests.
Sencha provides an app hosting service through its Sencha.io cloud services.
I have the following scenario:
We develop a silverlight 4 app for our customers, that will be used as an out-of-browser app. The app is working offline, i.e. app and database are on the users local machine. The app is using WCF-RIA-services to connect to the local database. The database will be an SQL Server Express, SQL Server CE or MySQL. We are using MVVMLight and MEF.
An external webserver is only used for updating the app from time to time or adding new modules to the app. To achieve this we do something similar as shown in Jeremy Likness blog (http://www.wintellect.com/CS/blogs/jlikness/archive/2010/05/25/silverlight-out-of-browser-dynamic-modules-in-offline-mode.aspx )
The reasons why we are doing such a scenario are complex. But to keep a long story short it is mainly for compatibility reasons for a later online version and we don't want to use WPF. So we need to get this working with Silverlight and WCF-RIA services.
Ok, that's the scenario and here's the question:
Do we need a local webserver in this scenario? The app is programmatically installed as out-of-browser, the database is local and connected via WCF-RIA.
If yes, which webserver would be sufficient? It should be installed and configured via an initial setup that is executed by the customer. The customer should not have to do anything with configuring the webserver.
Any other ideas or comments on this scenario? Any other possible solutions for this?
Thanks for your help

silverlight wasn't meant to be used this way I think. So it would be like when you are developing app in visual studio and use Cassini to see result - everything runs locally - but you still need a web server. Maybe more info here - http://www.infoq.com/news/2010/06/WPF-vs-Silverlight
I´m not able to provide with a full answer to your problem, as we are currently facing the same problem. (WPF not being cross-platform, Very specific hardware on some clients)
But I may share some of our thoughts on our type of Thick-Silverlight-Client:
To keep deployment etc. simple we use a self-hosting process (installed as background process)
We may not use RIA as the background process has to run using Mono VM (but for MS-only solution see Can WCF RIA Services be self hosted? )
Architectural thoughts on standalone "Clients":
Depending on your requirements implementing a server for each client communicating with the "main"-server by messages (NServiceBus) may be overkill. But if you want to use a client database if offline and silverlight for ui you should consider using an event-driven-architecture.
There is a slideshow on combining "Event-Driven-Architecture" & "CQRS" with Silverlight. But i would not use it as a blueprint more like an inspiration.

I'm in the process of providing a Web UI as an alternative to our current desktop UI for our C/S enterprise application.
When developing the client-side in our desktop version, UI developers could connect to any server so they only needed the client-side environment.
When developing a Web UI (Client-side JavaScript in the browser), we are bound by the browser's "Same origin policy" so the UI must talk to the same server from which the UI code is downloaded.
As far as I see it till now, the development scenario for the UI guys is:
Developer installs server on local
machine and runs it.
Developer edits the HTML+JS+CSS files on local installation.
Developer has to reinstall/update server on local machine each time there's a need to test UI code against new server behaviour.
This does not seem too comfortable, at least compared to our previous C/S style development.
Are there any other ways you can suggest to that will not require UI developers from installing and updating server side components on their development machine ?
Or anything else related that can simplify the development process ?
Thanks :-)
Editing in some clarifications:
I'm mostly interested in the aspects of UI coding, not UI design.
I need a lot of server interaction - getting data from RESTful web services, which are developed in parrallel - hence the need to have an up-to-date server
You haven't specified the development platform.
As far as pure HTML/JS/CSS is concerned, you don't need a server. The UI developer can fine tune UI components locally.
The moment you want to talk/integrate to Server (via AJAX, JSP, ASP...) then you need to connect a development server as now your changes have to be served by Server.
Most of UI fine tuning can also be done from Firebug
In our office when changes to styling are required we save the page as a local copy and send it to the UI designer, he makes his changes and we integrate them. So the UI designer don't have to maintain a development environment.
JSONP lets you work around the same-origin problem (with server support) -- check it out! If the front-end-in-the-browser developers are using a good framework suc as jQuery or (my favorite) Dojo, JSONP should be no harder for them than plain JSON.
Develop on a shared server, but depending on the size of the team.. that's challeging with respect to version control.
Or deploy automatically generated virtual machines with nightly builds, so the devs don't have to install, but always use a recent version.
In the case of UI developers depending on a common REST server, the UI development can be done on the local machine and the REST service should be on a central server. When changes are made to the REST service these should be deployed to the central server (when stable), so all developers can use the newest version (this also helps with testdata).
You could try using a proxy on the developer's machine where some paths redirect to the server and some paths redirect to local folders.
Hmm, I actually didn't really get any information on what kind of technology you're using. If - with UI Developers - you mean designers, which have to take care about the CSS, layout etc, then we do it the same as lud0h said. We (developers) send the UI designers a copy of the server-side produced HTML pages. They then edit the HTML pages according to accessibility guidelines, CSS and layout and send us back the outcome of their work. We use their HTML pages then for integrating them in our web applications.
If you don't just mean tuning CSS, but also to write JavaScript / Ajax functionality you HAVE to use a server with which you're communicating. As you said, normally this is done by having a local environment which is similar to the server-one. In .Net Visual Studio '08 provides an internal webserver, alternatively you have to install IIS locally. In Java environments you have to install Tomcat and related technologies. In my eyes this is a must. What you have to have is
Versioning system (CVS, SVN,...) where developers commit regularly (minutes/hours)
local environments where developers checkout the source from the repository and develop
Test server where you deploy on a daily basis (could be like daily builds) in order to test your running product
I guess this should be what a professional development environment should consist of. The difference to C/S application development is that web UI and web-client code are not that separable as a Client UI in C/S environment from the server-side. Unless you develop with technologies like GWT or Silverlight which are quite similar to C/S, just running inside the browser, but communicating over RPC calls or web services.
//Edit:
What I nearly forgot. Don't do something like developing on the server directly, meaning that all of the developers access the server's filesystem where the code, UI etc. lies!!
You can use CORS. a new technique just like Ajax, but with ability to make calls on other domains. so you will need only one UI on one server. think this can help you.
Sorry for my ignorance here, but when I hear the word webserver, I immediately imagine Apache, although I know people use Microsoft's IIS too. However since I've been hanging out here at Stackoverflow I've noticed lots of people use Glassfish.
Which made me wonder, why would I want to use Glassfish (in the sense that I'm interested, but I don't really understand why it might make my life easier). From what I read it's Sun's open-source derivate of Apache's Tomcat, thus I imagine it's a good (or great) quality product. But since I don't know its strengths and weaknesses, I don't know when it would be wise to choose Glassfish over another server. Could anyone elaborate ?
GlassFish is an Application Server which can also be used as a Web Server (Http Server).
A web Server means: Handling HTTP requests (usually from browsers).
A Servlet Container (e.g. Tomcat) means: It can handle servlets & JSP.
An Application Server (e.g. GlassFish) means: It can manage Java EE applications (usually both servlet/JSP and EJBs).
You should use GlassFish for Java EE enterprise applications.
The need for a seperate Web server is mostly needed in a production environment. You would normally find a Application server to be suffice most of your development needs. A web server is capable of holding larger number of active sessions and connections, thus providing the necessary balance without performance costs.
Stick to a simple web server if you are only working with servlets/jsps. It is also to be noted that in a netbeans environment, glassfish has better support than other App servers. In the context of eclipse though, WSAD and JBoss seem to the preferred options.
Glassfish will soon release the modular kernel.
This means that the containers you need start up and shutdown as you need them. I.e no EAR deployed, EJB container won;t start up. This seems to have made it very good for development as it can start and stop very quickly. This takes it a lot closer to development environments like Rails (where redeployment is a massive part of your development)
I have used GlassFish server for developing Web Services.
It provides a very interactive Admin Console where admin can test the Web Services.
I really find it helpful while developing Web Services
