I'm working on project using GWT (with Vaadin) and I'm looking for a good, preferably, integrated flow chart library. The library can be commerical and preferrably is integrated with Vaadin.
Any recommendations?
I would go with mx-graph gwt wrapper with vaadin:

I am new to sakai, i want to add my own tool in sakai source code like announcement,syllabus...etc That tool having some my own functionality for this what i have to do, how can i develop my own tool in sakai.
Thanks.
Use one of the archetypes to get you started, then customise it. When you are comfortable you can change the UI layer to be whatever you like.

If you are looking for a solid "base" tool shell to begin with tool development my recommendation would be to start here: "Sakai Wicket Maven Archetype". There are a few other very good archetypes available but are often outdated and may cause you some problems based on my experience. This has been the one I've had the most success with.
This uses Wicket but does not mean you have to use Wicket to develop further with it. Make sure to pull the 1.2 version as last check the binaries for the others were not available yet so replace -DarchetypeVersion=1.4.1 with -DarchetypeVersion=1.2 It will compile and deploy successfully as a tool "as-is" that you can modify as needed. It also allows you to code in Java to directly access the sakai API and pull from its database or even add your own tables. I've successfully used it with NetBeans 8.0.1 and MySQL 5.6 under Windows 7 with Maven 3.2.3 and Sakai 10.1.
The code is well-documented and is no-frills but with enough varied functional use examples to allow you to do "almost" anything you want. The wicket manual is 600+ pages but in my experience you should be able to accomplish a lot just by looking at the code in the archetype.
I am thinking of developing a Ext GWT "GXT" 3.0 module that I need to embed to a GXT 2.x web application. Is it a good strategy to load a GXT module in a iframe. I mean, so I can develop the new module using GXT 3 and still "embed" the module in a GXT 2.x based web application. The application is quite big, so I don't think that there will be anyone in the project team that will be able to adapt to 3.0 just yet.
It is possible to run them together in the same project thanks to them using a different namespace.

Also if you plan to convert your older GXT2.x modules to GXT3 there is a legacy module to help with the transition. See :

I am not a web application pro but need to start working on a project so I need to know if pyjamas ( or shall I say the javascript generated o/p of pyjamas ) is as good as pyqt in terms of 2d graphics and widget features. I have a desktop python application which has some rich 2d graphics (with animations / collision detection etc..) implemented using pyqt.
Now I am specifically looking for equivalent web client with similar graphics and widget features . Does pyjamas support all the pyqt UI features with same look and feel??
I am also exploring GWT for this since I believe GWT has a good set of UIs and also supports decent 3rd party tools like vaadin,smartgwt but my preference is for pyjamas because its python and I am writing a equivalent pyqt based desktop app so am more comfortable with python then java. Also am not sure if GWTs look and feel would match with that of pyqt based UI on windows.
Any insights would be very helpful
Thanks in advance

Probably too late, but if anyone else would need an answer,
Pyjamas' widgets are mostly same as GWT's (most are direct translation from GWT, but we have some own widgets too), and do not target Qt, GTK or any other toolkit.
If you are looking into using webkit, you could get best of the two worlds, and use Pyjamas with PyJD. This way your very same application could be compiled into html/css/javascript and run in web browsers and at the same time you could run it in pyqt-webkit, xulrunner or mshtml with original python code.
I am a newbie to AspectJ and to learn it I am trying to search for some open-source simple applications that use AspectJ for the web but I am unable to retrieve any. I am trying to build a filter through this technology but I am not able to find any working examples that are suited in particular to Eclipse/Tomcat.
You can get (many variations) of a simple e-commerce application built using Spring+AspectJ from http://manning.com/laddad2 (click on "Source Code" link).
Not sure they're specifically targeted at Tomcat, but the examples at
Eclipse AspectJ Sample code ought to give you a start.
Well the topic says it all. Can I use google web toolkit to generate my views to be used in Castle Monorail project and render it through nvelocity view engine. Is it at all possible?
I don't know of anyone that has tried this, but GWT is a server-independent technology so in principle I don't see why it wouldn't work. GWT needs some server-side plumbing which you'll probably have to write yourself (again because I haven't found anyone that has done this before).
You might want to check out Script# which is similar to GWT but you code in .Net, it has MSBuild support, Visual Studio integration, etc.
