I have a desktop application, to use that I need to login to it every time. But I want to automate this login process.
I want to write a little program which will:
load my desktop application (in a scheduled time)
type the user name
type the password
click the login button
My concern is, is this possible with a Desktop application? If possible what is the path I should follow?
I'm have worked with both Java and Ruby, so if I could get something developed by those two languages that would be great.
This would be around a four-line script in AutoHotkey, as it has function primitives that closely map to your operations.
I would advise using AutoIt if you are on Windows, it can do everything that you need easily.
http://www.autoitscript.com/site/autoit/
Also useful if you like python, there's a cool program called Sikuli that you should check out.
http://sikuli.org/
It can be done without programming. There are many applications that can save a user's scenario and repeat it many times !!! (that is helpful for stress testing).
Take a look at IBM Rational Robot. You can also find many similar free tools.
More details about your test environment (Windows, Mac, Linux) and what the technology the GUI is made of (Windows GUI, Qt, embedded browser), etc. would be very helpful for determining what solution is best for you.
If you are one Windows and dealing with native controls, RAutomation is a great gem that should do what you need. It even has an AutoIt adapter mode which makes it a strict superset of AutoIt functionality.
If you need more power, consider checking out the Windows UI Automation framework. It's mostly in .NET but you maybe able to find or write a Java or Ruby wrapper around it. See a .NET example here.
If you are dealing with a UI which is an embedded web browser, then consider using watir-webdriver to drive it. You need some platform specific code to get the embedded browser instance and bind to it. The rest should feel just like a web application.
Finally, the mention of Sikuli is certainly a good one for being able to deal with any UI without needing an API. It's also Jython (yay JVM!). That said, I've found it to be fiddly and brittle, even more than typical UI testing due to its lack of identification of elements based upon either IDs or some kind of object hierarchy and relying solely on appearance. That said, it's really quick to be up and running so give it a shot.

I'm creating an Android application which will access data using a restful web application.
I have quite a lot of experience with Java, but minimal experience with PHP.
Having looked online, it is difficult to determine which language is more suitable, scalable, portable etc.
I'm hoping that the Application may one day have many concurrent users and therefore I need the most suitable option.
If anyone has any experience writing a web application in either language, I'd be really interested to hear about your experiences, and any problems you faced.. i.e. for a java web application do you need a tomcat server or another embeddded to server for it to be able to run?
Thanks, for any answers, Matt.
If you already have experience with java, I would suggest you use the following to build your REST services: http://restlet.com/
Its very easy, and efficient. The performance is very smooth. For PHP, you will have some learning curve, and also there is no standard. Mixing java with PHP is like combining a VERY STRICT LANGUAGE (java) with a VERY LENIENT LANGUAGE (PHP). So its safer to be on the same language.
Tutorials:
Official tutorials to get started: http://restlet.com/learn/tutorial/2.2/
Good step by step tutorial with screenshots and code snippets: http://java.dzone.com/articles/restlet-framework-hello-world
Short:
Take JAVA!
Always choose the language you are comfortable with. Also I think Java is better suited in the end.
PHP isn't my favorit. Most of the people like it, because it is easy to start with. (It was also for me the second (non Browser) language I touched.)
Framework Tips
WebFrontend: Play Framework
Back End&Scaleability: AKKA
JSON: Gson
Long:
Scaleability in the meaning to scale to lots of concurrent users:,
is more a architectonical issue, as a question for the right language. You can write scaleable software in any language. The difference isn't the scaleability of a language, but it could be the performance. One language will take longer for the same task as the other one. But you could always throw more Servers in, to scale out.
Architectures to consider if you want to scale out, are in my opinion message based designs. My favorite is the actor model, there is a very good framework for that in Java, the akka framework (production proved). But I think you first should get your software running. If you get enough users... scalability problems are the problems you like to have (they mean you have users).
Scaleable doesn't only mean, that you can scale to many concurrent users. But the ability, to handle the complexity of the software or can handle concurrent development and so on (your team will grow, thats also a problem to handle). In this topics Java is as clearly static typed OOP language, better suited.
Also the performance will not be as good as in Java (it is a interpreted language). But there are always options. Facebook started with PHP. In an interview one of the lead developers, told that PHP isn't that scaleable, because PHP wasn't designed for OOP. But the performance issue was handled, through writing a compiler for PHP (outputs C++). [If if find the link I will post it] .
Update the PHP Compiler is Called HipHop and it uses HHVM (Hiphop virtual machine), Facebook developed it after excessive CPU usage
You can consider looking at https://jersey.java.net/ As a web container you can use anything like Tomcat. I have used Google App Engine in the past.
To get started quickly with Java look into http://dropwizard.io/, using less EE frameworks and more standard Java.
Has Jersey for REST and is supereasy to run.

I'm starting a new web based enterprise application, and I'm thinking of using Wavemaker.
I'm a fairly experienced java-ee developer, but it seems to me that even in this case, WaveMaker still makes sense to develop the application fast and focus on the business logic.
My questions are :
1- Are their any drawbacks to this platform
2- Can I do all the normal things from the server side easily (like sending mail,building birt reports, adding jobs)
3- Can I freely manipulate javascript (for example for specific animations, using plugins....)
4- Can I integrate realtime processes, like websockets ?
Thank you
I've used Wavemaker in an Enterprise application with success. We used quite advanced features such as heavy use of backend logic based on JavaServices, an run-time SQL database selector made inhouse, JS plugins for the frontend, obfuscation etc
We later recruited a devteam to take support of this application and, although the community is small, the team learn quickly and was able to maintain the code base.
As I see it, Wavemaker is a excellent tool if you like to:
deploy a web-based CMS for your midsized SQL database
deploy a smaller web control page for your java back end system
To answer you questions:
1) Small community: Although the community is friendly and on their toes, it is too small to ensure the type of feeback you might be used to. You will have to spend quite some time banging your head to the wall when you try to go beyond the example applications.
2) Yes, you have all the freedom you would expect from a Java backend. Simply said; each REST api is assigned to a Java Method, its up to you to implement the logic. I have built wavemaker on SQL, mongoDB. With email interactions, data parsing, file upload/download etc You name it
3) Yes, you can add JS plugins and customize the scripts generated by Wavemaker. You might want to make sure that you don't edit the auto generated JS, since they will be overwritten. but as soon as you found the right entry point you are free to customize just the way you like it.
4) Yes, since you build you own back end in java you are free to open up any type of communication you like to have. And since you are able to customize the front end js you will be able to read this data. But as I said in question 1 - there will only be a small community helping you
So to sum it up:
I vote for Wavemaker, but make sure to only deploy it if you application will be similar to the templates/demo provided, if you build a unique system you might like to look into other solutions.
All choices have drawbacks. There is not a lot of WM expertise to be had. You'll need to deal with some issues in terms of the library at hand, dojo, spring etc instead.
you can,but it requires some java knowledge. You are operating in a spring MVC you can
you can, you are operating in a dojo client there
possible, probably. worth the effort, doubt it.
1- Drawbacks- It's enterprise focused platform, so will require own effort to learn it.
2- Yeah, you can do pretty much all normal things (at least from my experience, till now)
3- The tool has kind of open-source configuration so its easy to manipulate or customize your codes if needed
4- From my experience, WaveMaker has one of the best and most diverse integration options available.

I plan to build a product that would let users do what Google Docs is doing today (although, not as good as Microsoft would do it) - edit word docs. The reason I can't use Google Docs is coz I need to build something new on top of it - like annotation support/ metadata support and all that.
So, if I were to start from scratch, How big a task is this going to be? Can I start with some fancy JS libraries and extend them or something? For instance, something like yahoo pipes, non-flash, pure JS/HTML5 + ajax based web application. Are there open source alternatives that I can make use of?
Is it going to be pure JS editor(on the client side)? if so then.
Keep it modular(or try at least). Try Sea.js to separate stuff and load it on demand.
You need some editor to edit text of your doc: TinyMCE, CKEditor, jWysiwyg etc. (all of this uses iframes and contentEditable property to change page content on the fly).
Some proxy server to exchange information about docs(and keep info about docs too). Depending on the performance needed you can start off with Apache and PHP and MySQL(windows WAMP package).
2.a For php server side you need some framework to get your logic together. Maybe Symfony2, CakePHP or other MVC frameworks(cool to use).
For real-time update you can use Node.js and IOsocket(WebSockets) to create peer to peer communication between users(one changes text, the other sees it immediately). HTML5 browsers only tho.
The amount of work needed is depending on your requirements for this project. First of all create a specification, collect requirements, analyze the problem, implement, then test it.
4. For testing you can use some headless testing frameworks(still with node), jstestdriver etc.
That is what came to my mind first, Good luck.
Google Docs is an enormous and deceptively complicated application. It implements pretty much everything from scratch, including text selection, caret, text measurement and positioning and does easily the best job of this that I've seen in a browser. They've managed this, I assume, by having invested in an elite development team over a number of years.
All that being the case, trying to write something of the level of Google Docs is almost certainly a non-starter. You can get limited editing capabilities using contenteditable elements, but taming that particular beast is also an extremely tricky task and I'd recommend using one of the larger editors (CKEditor or TinyMCE, for example) at least as a starting point.

I am new in web development world
(from microcontrollers to web is a really long path)
Having a Java software (.jar) running, it's just a background process sending/receiving info through sockets, with no interface.
I would like to make a web interface to it, and I need some guidelines, about how to confront these topics
The code:Should I keep it being .jar or it's recomendable to go into .war and deployment? other?
The html/javascript code:Edit the page with an wysiwyg editor? and/or edit the html code within IDE ? / use GWT to develop everything within java? other?
The http server: Use an Apache Server, tomcat? implementing it within java with HttpHandler? other?
The Data: Data is actually in classes, objects and some persistence with writeObject.. should I leave it that way or "web development" is compatible better with mysql or some sql? other?
Just searching for something simple and actual tools, and to avoid reinventing wheels
Experienced web developers, your advices are very welcome!
I would suggest that you embed Jetty and then add some servlets to connect your existing code.
It really works !
If this is an accurate summary
You have a (presumably) proprietory protocol exposed over a socket interface.
You desire to access the same function over HTTP, with a Browser based GUI.
Then I would approach it like this:
1). Consider whether to refactor your current code - In concept you have a "core" with a socket interface. What you need is the same "core" with an HTTP interface ... except maybe that doesn't nicely work? HTTP is effectively stateless, with request/response pairs. You might have something much cleverer with your sockets so some redesign might be needed, or maybe it just fits, or even you need to get really clever and use streaming, or Comet or something.
So first decide on an approach. Let's take the optimistic assumption that a standard HTTP model works for you. Then:
2). You may as well use the servlet API, so TomCat or WebSphere Community Edition or any readily acessible servlet engine will do. Just write a few servlets that front your "core".
3). Tools, Eclipse works. Plenty of alternatives, but favour an IDE.
4). Especially when moving to the UI part, editing HTML, or JSPs something WYSWYG is useful. Things get a bit tougher if you want to do a Javascript-based UI - there are products out there but I don't think they're as mature as things such as Eclipse for Java.
I recently learned Spring. It's a very lightweight framework, and very easy to learn and use.

It's been a while since I've done any website with with Java, and am wondering what framework options are out there for Google App Engine.
What framework would you suggest for someone who has no real preference?
I like Ruby On Rails, and am getting into Django, and like that as well. Professionally I'm a ASP.NET developer so I have the most experience with that, but I'm looking to expand into other technologies, and patterns.
It would be nice to have more experience with MVC.
thanks,
Mark
The Spring Framework works, although you have to make sure commons-logging isn't called commons-logging-1.1.1.jar (as I had it in maven conventions, Google provides a jar with this same name and there are classloading issues as a result). So, Spring WebMVC is confirmed to work - which raises the possibility that its sister project Spring Webflow will work - though I can't say I really like where Webflow 2 completely diverged from Webflow 1.
Also, I have yet to find a framework that really encompasses the notion of "saving and continuing" well - users often like to do that, and Webflow 2 really tries to make programming that as difficult as possible if you use its persistence context inside the flows themselves.
Wicket works on App Engine, you just have to make a few tweaks to the configuration.
I've had variable experiences with Vaadin on GAE. Some applications are almost as fast as with localhost, but sometimes the latency is freakish. Probably depends on which server geographically your application gets deployed on.
Try ItsNat, more info.
Don't use it for a simple single reason - vendor lock in.
What happens if the service doesn't meet your satisfaction?
What happens if you can get a better deal (Java hosting) somewhere else?
What if you want to sell your product - where's your platform?
What happens if Google decides App Engine is not worth their effort and close it?
as a side note Google have and will close services that are unprofitable. A simple search will reveal many, escpecially in theses trying times.
Do you care about vendor lock in?
If you don't care about losing your effort and time invested and perhaps want a platform just to play with then I suppose it's OK but for anything serious stay away.
