I have found this question in my University Past paper.
I know what is enterprise application and i also have a detail knowledge of HTML.. But i could not understand what is the specific purpose of html in enterprise application development. I search this question in different ways from google but no site explain it in any way except the one which is (https://answers.yahoo.com/question/index?qid=20160825012934AAuuG4g)
This site says (If the application is web based, it needs HTML to display its GUI.)
GUI can alse be displayed using JAVA.
I want someone explain me in a better way
Yes, you can use Java API also for Web Based Enterprise, Its upto you which domain is used for creating Enterprise application..
An enterprise application can consist of anything. It's a big business application. The technology used for it can differ wildly, as you pointed out, Java can be used to display the GUI.
Most businesses opt for web-based applications utilizing HTML5 and Bootstrap. It makes mobility less of an issue when someone is out in the field (if that is one of the requirements) and easily maintainable etc.
Or you can have a windows application as your enterprise application, using .NET, Java, whatever to display an interact with your desktop. This means people have to be AT work to DO work because the application is installed on a PC, not compatible with Linux etc.
It's all about what the business needs are. HTML is just a technology that CAN be applied to an enterprise application

I created a webpage several years ago. Back then I was using Adobe GoLive! to achieve that. But now, there is no adobe GoLive any more and I don't have a useful application for creating a web project. So what I want to achieve is: a good looking online presence for my project. I want to use the new stuff as well, like HTML5 and CSS3. I don't think that I will need beans or J2EE, because it is more about the design and not the functionality. Later on I will include the web project into my Apache server. So the question is: which tool can help me to develop a modern website, what would you advice?
Thank You
Actually I use NetBeans 8 for the following reasons:
it's very strong and containt so many features
i supports ftp
ii supports CSS3 , HTML5
iii powerful , autoComplete
it's open-Source application so it's free
it keeps the history of your files and saves all the updates so you can restore any file
situation you made before
it's easy to use.
It's a good programming tool
SECOND: I suggest using xampp instead of abache server
it actually includes abache and some other features like mysql
so it's easy to deal with it instead of dealing with many programs :)
I strongly recommend 'IUEditor'
Free license. Ownership is 2,000$, monthly license is more than 50$. But if you request startup license they offer free license.
CSS3 and HTML5 : you can use any kind of website.
Back-end support : That's only one web editor which supports backend, such as django and angularJS
Supports GIT.
I tried more than 10 web editors, but IUEditor works best.
I have been involved with web development applications for more than 3 years now, using c# and microsoft stuff. I am now looking into, and researching, whether it is possible to use webservice, perhaps with Java as the core, and multiple languages and tools, such as HTML5, php, javascript, etc to interact with users. Some of the things I need to be clear about, if this is possible, are:
Is such method secure? What are the considerations that need to be taken into account and how can the security part be properly implemented?
Are there constraints to what type of interactions the web site can provide, such as sending forms with a lot of details, or long texts?
Some elaborations and examples would be appreciated.
What you're describing are called web apps. They're so ubiquitous you used one (StackOverflow) to ask whether it's possible.
To answer your questions:
Yes, it's possible to make it secure, and no, it's not easy. See Wikipedia for a starting point for how to read up on this huge topic.
No. HTML5 web apps are extremely capable. If Microsoft can port Office to the web, your online form will be just fine.

I am new to app development and chose C# and xaml for apps. But things didnt quite go well. I aint a full time programming freak; can just manage an hour or two a day after college studies and with xaml my head really hurts.
Recently i came to know that even html5 can be used to make apps. So my question is this :
Should i continue with xaml or switch to html5 ?

My requirements are :
1) Shouldn't be too time consuming
2) I will currently focus on light and simple apps ( Games maybe, but not in near future)
3) They should be available to both wp8 as well as desktop, and if possible to other platforms as well.
(I happen to know c++ and Java at intermediate level.)
While either solution could work, here are some things to consider. I'm going to assume you mean Windows Store applications when you said "desktop."
1) Shouldn't be too time consuming
That's very difficult to say. If you're not familiar with C# and Xaml, there will be a learning curve. You mentioned you know Java though, so the language shouldn't be too much of a challenge. If you're interested in quick to build, I'd suggest you start with Xaml and C# and use the Xaml visual designer to gain some experience and ignore the Xaml output at first. By default, like a web page, the layout system is not absolute and often uses various types of panels (grids, dock panel, etc.) for layout.
Microsoft has a lot of great examples on MSDN that would allow you to both learn more about your options, but even contrast the coding techniques. Having taught someone at work in a little more than an hour how to get started and be productive, you might want to give Xaml another go.
2) I will currently focus on light and simple apps ( Games maybe, but not in near future)
Your definition of light and simple isn't specified. You could create applications that meet that requirement with either platform. If you're building games, the answer changes and becomes more complex. As you're still learning though, I'll not talk about that here.
3) They should be available to both wp8 as well as desktop, and if possible to other platforms as well.
Today, there are 4 common ways of developing an application for Windows 8.1 desktop:
Xaml/C# (C++ is also an option here)
WinJS/HTML/JavaScript (WinJS is a Windows store application-only framework)
Either of the above, hosting a web page (either from a web server or local in-app)
C++/DirectX (for games)
Currently, there isn't a way to use WinJS or the same code for option 4 on Windows Phone. So, you'd likely narrow your options to Xaml or a web page view. While you can't take Xaml and necessarily use the same Xaml on both platforms, the patterns and development experience are very close. By using a "portable class library", it's now possible to share the common business logic between the platforms.
A Xaml approach would allow, without extra effort, the application to be a native experience. Th application would have the appearance and behaviors of a Windows Store application. If you went with just an embedded web page approach, you'd be on your own. I will not take on the experience and look of Windows. If you aren't familiar with doing reasonably complex HTML and CSS, an embedded web page solution may be too time consuming.
(I happen to know c++ and Java at intermediate level.)
Here's a few links that might help you:

This will likely help you with either choice.
Traditional Windows Desktop applications
If you want to build a traditional Windows desktop application and not a Store application, your options are similar, with the exception that you might choose to build your application using WPF. windows Presentation Foundation was the predecessor to the Xaml used in Windows Phone and Store applications. It's not identical, but the knowledge of one transfers well. You can also host an web page inside of a "desktop" application. I've done it frequently. If you're trying to build someone "modern" though, learn the Windows Store frameworks.
If XAML hurts, I say go HTML5. I don't understand XAML very well myself, so I use HTML5 for my Win8 apps.
Regarding your requirements, HTML5 fits 1&2 perfectly. It's not very common to write desktop apps in HTML5 though, so your options there will be quite limited.
We are looking at building a GUI application having the following attributes -
* approx 100 screens
* approx 200 users
* interfaces with 8 different legacy applications (protocols tbd but we are assuming web services will be exposed)
* has a separate data store for storing authentication and authorisation info along with few other information.
We are trying to avoid spending any money on procurement of physical servers, application servers etc.So we thought instead of building a web application , we could develop a standalone GUI based application that could be deployed on users' desktops considering that the users are less and the access to this application is confined to our organisation.
We were thinking of Java Swing as one of the options to consider. Is it a good choice? Please advice on the other options that we need to think about. We thought MS products would involving licensing costs to buy the product hence we are looking at developing the application using some free software tools.
Thanks a lot!

I really like Swing and have written many applications with it, but I'm not sure the argument that you will get a cheaper solution because you have to procure less physical servers is a good reason for it.
There are other ways to use computational capacity on the client side. For example you could use SmartGWT. With a browser based solution you get easy deployment and have no problems with client-server communications (i.e. no proxy hell). It's possible to get all of this solved with a standalone GUI, but it requires experience and time (== money).
I think a standalone GUI is a good idea if you need a "rich" user experience and tight integration with the native environment. Web apps are generally less snappy and not so well integrated. If it's just about editing data on a server, the standalone GUI does not really have any advantages.
I won't rehash what we talked about in the comments. It seems you are focused on java gui solutions. With that said there are alternatives for developing gui applications with free tools. Just to name a couple, you could develop your client with Adobe Flex or Adobe Air, use python, php or ruby and GTK, or develop a windows GUI app using c# if your target os is windows. Similar to Air, Microsoft Silverlight is an option. Java is not the only solution.
Many Java gui apps are written using swing. The major competitor to Swing has long been SWT which is used for eclipse and by IBM. Javafx is a newer/alternative platform Sun/Oracle is behind, you should also look at. To be complete, you should also take a look at qt jambi that lets you develop in java against the Qt framework.
I want to build admin panel for my site!
But, I'm puzzled between Silverlight and HTML.
I believe Silverlight give me greater control and easier from HTML
What do you advise me to use in terms of best, security, and strong controls?
thanks,
In spite of what everyone says, Silverlight (and even Flash) is not everywhere. There are still a lot of users and browsers that don't have or support Silverlight. Of course it will be a great application if built using Silverlight, but you cannot just ignore the ones who don't have it installed. If you go with Silverlight, you will still need to implement a simple HTML version of your Admin Panel.
Having said all of this, it really depends on your user base, scope of your application and the type of environment it is going to run in.
Guess it depends on your audience. For an admin panel, unless you need the maximum reach to various devices and operating systems, Silverlight is probably fine and will probably allow you to whip something together very quickly using RIA services or WCF Data Services.
As far as security goes - you'll want to secure your services the same way regardless of whether you're using a HTML or Silverlight client to access them. Basically, just never assume that your client is the only one accessing your services. Don't send any data down to the client that you wouldn't want exposed and don't trust any input from the client without validating it first. This is where RIA services can help as it can coordinate validation rules on the client and server.
I'm not really familiar with Silverlight so I can't judge anything about it. With regards to html I guess Its a better choice if you want it available in many browser. If you heard about html5 I think you'll have a second thought about it. Well it still base on your needs.
