I'm looking for a java AJAX framework which I can include into my existing webapp. I've found sweetDev RIA . Are there such other frameworks which I could look into it?
I'd take a look at DWR: Direct Web Remoting. It allows you to directly call Java (web services) from JavaScript in a really intuitive way.
Last couple of years, I have been developing rich looking web applications with icefaces. It is pretty cool, ajax is buit-in and it blends very well with jsf. If you use icefaces, javascript is not required anymore. In our web project we use javascript only in couple of places.
Here is an excerpt from icefaces homepage: "As a leading open source Ajax framework, ICEfaces is more than a Ajax JSF component library, it's an J2EE Ajax framework for developing and deploying rich enterprise applications (REAs). With ICEfaces, enterprise Java developers can easily develop rich enterprise applications in Java, not JavaScript."
I suggest ExtJS (with jQuery underneath), but you might prefer GWT. I think it's easier for Java programmers who are seeking to wade slowly into JavaScript waters.
I would really check out extjs.com. It is the most feature complete javascript component library I know of. The components are fast, have beautiful default styling, and the API is very powerful. AJAX support is also excellent. Most of my current web development include extjs in some way.
It's very easy to use this library with java. Most of the time, I just have some server side component that returns data in JSON.
There is also ExtTLD; a tablib wrapper for extjs. I have never used it myself, though.
Google Web Toolkit ( GWT )
you can also use Apache's 'Myfaces' project http://myfaces.apache.org
Its a JSF implementation, and also has components with in built ajax capability.
You can try SweetDevRia, it's possible to add ajax in your application without writing Javascript. You only need to use JSP tags

I am planning to write a medium scale web application. The server side technologies will include Java, Hibernate, MySQL and the client technologies will include Html, CSS, Javascript and Jquery.
I am looking for the best suitable Java framework for developing web (Struts, Spring, Wicket and so on).
I consider myself heavy Jquery user and I really prefer to do client side stuff.
Wicket for example has modules like the date picker and other modules (AJAX) that should make life easIer with javascript and acts like a replacement to it. But I really prefer javascript.
I thought of writing an application with client side and Java Web Services.
What do you think?
Do you know a framework that isn't afraid of Javascript or don't
suggest replacement to it but tools to use it?
Component-based frameworks generally provide ready-to-use components, that come with their own JavaScript code. If you don't like this, I would stick with action-based MVC frameworks, which generally don't care about what you use at client-side.
My preferences go to Stripes and Spring MVC, but YMMV.
I'd recommend the Play! Framework.
It is a MVC based framework and you can use hibernate, work with a MySQL database and it offers templating for easy HTML generation as well as working well with CSS and Javascript (even includes latest JQuery in download). There are also tons of modules you can add to your project to make development faster and easier.
Play 2.0 should be released fairly soon (currently available in beta) which provides support for CoffeeScript and Less CSS (see here) amongst many other new features.
Edit
StackOverflow answer showing how easy it is to create webservices in Play: https://stackoverflow.com/a/4513047/681807
Well all the framework you have mentioned (struts, spring, wicket) , none of them afraid of javascript.
Like in Struts2 and Spring they have provided build in ajax support for developer like me who is more comfortable with serverside development than client side work (ajax/jquery fancy stuff).
Its on individual how he/she is using JS with any existing framework and you are even free to use simple HTML at you client side with whatever JS way you want to apply to your UI.
Framework support to UI is always intended to provide a close integration to the server-side so as to speedup the overall development time.
In Short i can not recommend any framework as that will dependent upon you project requirements which fits perfectly as per your need, but none of the framework will stop you to use JS in the way you want to use.
Do you know a technology which can provide me a portlet-like interface?
But I do not want to use JSR 168/268 portlet specifications and a portlet container.
The reason is: My web app is a product which can be installed on the client's server (it can be weblogic/websphere/tomcat).
Packing the portlets container along with my application to be installed on clients web server is just too much.
Besides, there are a lot of features this technology offers which I don't need. Actually, all I need is the porlets look and feel (dragable and customizable windows,adding and removing windows and so on).
I know there is also the possibility to do it with client technology (like jquery) and that is cool, but I would like to know if there is any kind of java technology out there which will also give me that.
So, if you know something like a struts or a spring-mvc component library which does this job or maybe a third party product, I would like to know.
If you think my whole approach is wrong I would also like to know that.
Take a look at gwtportlets. From their site;
GWT Portlets is a free open source web
framework for building GWT (Google Web
Toolkit) applications. It defines a
very simple & productive, yet powerful
programming model to build good
looking, modular GWT applications.
The programming model is somewhat
similar to writing JSR168 portlets for
a portal server (Liferay, JBoss Portal
etc.). The "portal" is your
application built using the GWT
Portlets framework as a library.
Application functionality is developed
as loosely coupled Portlets each with
an optional server side DataProvider.
Take a look at the demo here
Another suggestion would be JSF 2.0 which provide AJAX support for updating part of the HTML-page out of the box.
Have a look at this series to get an idea of the possibilities:
http://www.ibm.com/developerworks/java/library/j-jsf2fu1/index.html
I am trying to build a web application, similar in feel to something like GMail, with one persistent AJAXy page.
I am told that GWT is the way to do this most effectively. However, I also want a framework that I can use for other things besides single AJAXy pages. Is GWT more scalable than this, or should I spend the time and build this thing in ASP.net MVC or Django?
I should mention, I'm trying to LEARN a framework that will be suitable for me to do whatever in.
You can use GWT also for parts of the page (a single widget or two), but yes, you are right,
even then it is geared towards the case where you do not refresh the page it lives on.
GWT works fine for both cases. I've written a couple applications at work with it, and I haven't had any trouble with multi-page navigation. As Thilo also mentioned, you can use as much or as little of GWT for manipulating your page(s) as you need or want.
You can do both styles of applications in ASP.NET MVC or GWT.
GWT makes it easier for GMail-type applications eg: web applications which mimic desktop application functionality.
On the other side, ASP.NET MVC is easier for dynamic sites. EG: This site is built on ASP.NET MVC, and if you look at it, its behaves more like a dynamic and interactive web site rather than a desktop-like application.
So its just easier to do web sites in one, and web applications in the other. So I'd think about what type of app you'd rather spend your time on and choose the framework accordingly - Realising, of course, that you can do both types of applications in either.
The nice thing of GWT is that in the end all you have is HTML and JavaScript. You can combine it with any other technology.
You can use GWT for the one page that needs ajaxy stuff and the rest with something more traditional.
Or you could even write everything with another framework and then put a GWT widget that needs more AJAX behaviours in a dedicated location of your page.
If you want to stay in the Java world you can use JSP,JSF, Struts, Wicket, or any other framework.
If you want you could even just combine GWT with a .NET or PHP. Just don't use the GWT RPC in that case (use JSON or some simple XML encoding instead).
I'm relatively new to Java EE and I'm in need of a framework that will simplify AJAX for me.
At the moment I have code that uses the dojo toolkit to draw a graph, but I'd like to have the graph updatable via AJAX. is there a good framework that allows me to do Ajax call backs and insert and run javascript into a page?
If so is there a good tutorial on how to use this framework?
My only experience with Ajax is using Telerik under ASP.Net.
Dojo does AJAX too.
Normally I'd recommend jQuery for this kind of thing but you're already using Dojo so you should probably use that. The two can be used together however, if desired.
There are some JSF component libraries that got more or less ajax support. ICEfaces for example, makes all the standard components ajax'ish and offers server push techniques. Check out the jsfmatrix to get an overview.
Im porting a project from php to java. The project is a web-app based on php and ajax techniques with a javascript front-end. What java-frameworks would you use for something like this?
Does the result have to be written in Java, or does it just have to run on the JVM? In the latter case, you might want to consider Grails, which uses Groovy, a Java-based dynamic language that compiles to Java byte code and has full access to the Java standard API.
How well do you know Java?
Why are you porting it?
I can't really tell based on your description, but there are lots of Java web frameworks out there. Pick one. I prefer Spring.
I fear that you're about to be very disappointed. I anticipate a lot of questions like "Why can't I do X in Java? It's easy in PHP!"
Apache Wicket is a possible java based web framework you might consider. The default would be the java servlet and jsp frameworks.
without seeing the source code - you will need a complete rewrite. just "porting" will probably not work.
out of all available frameworks i'd recommend two: wicket if you want clean lightweight technology. with ajax. jsf/seam if you are in a corporate environment where it it easy to get tons of experienced developers.
I really like Stripes.
There's a really good book out on it too. Stripes ... and Java Web Development is Fun Again.
This question seems to come up alot. Related:
What Web Application Framework for Java is Recommended?

Does it make sense to use a framework for a simple java web app?
What language/platform to choose for a new web application?
In my opinion you would still do the same but generate the html with JSP and javabeans instead of php. javascripts and ajax will still work without a problem if the outputed html is the same.
It depends by the size of your project, the features and your resources.
If the project have'nt a lot of particular needs you can use Struts. Thsi is a stable framework, not really advanced but simple and powerfull for the development.
Another frameworks more recent and advanced are Spring and Wicket.
Before you start, I recommend you to do a check-list of your need:
Do you must porting a O/R mapping too?
Have you a stable developer knowing Java/J2EE?
Do you think to add some feature during the porting or in short-run?
etc etc
good luck! :)
I would port it to GWT
Google Web Toolkit (GWT) is a development toolkit for building and optimizing complex browser-based applications. Its goal is to enable productive development of high-performance web applications without the developer having to be an expert in browser quirks, XMLHttpRequest, and JavaScript. GWT is used by many products at Google, including Google Wave and the new version of AdWords. It's open source, completely free, and used by thousands of developers around the world.
