I am just starting to learn ADF and I am tasked with examining how ADF's gantt chart works.
I have completed Oracle's tutorial of it, however I feel that all the tutorial teaches is how to use the tutorial.
Basically I am looking for a good tutorial to show how from an empty project:
create a collection of dummy data [ not from a database]
attach a view to the data and ideally a chart, doesn't have to be a gantt but that would be a plus.
Thanks in advance
If you are a partner or an employee, check out the Oracle University training titled Oracle ADF 11g Overview. Otherwise, there's a blog post JSF/ADF Faces for Dummies and another useful link.
The tutorials and documentation is almost useless..
Oracle has an online demo of the dvt components here
You can download the workspace for this demo here and examine how they do things. This helped me alot!
Take a look at oracle.dvtdemo.gantt.data.SampleModelFactory which creates a dummy datamodel for the Gantts.
Oracle ADF is a complex technology, diving in trying to understand how the ADF's gantt chart work is very ambishious(that is only my opinion). I come from an Oracle forms environment and have found this tutorial very helpfull to help me understand how the whole framework fits together

I want to learn gridbag layout and i have been searching the net for good tutorials but havent found any. Can someone recommend from where this can be learnt?
You might have not searched well.
If you had searched well then how did you missed this: Oracle java tutorials: How to Use GridBagLayout
For examples visit this: Java Tutorial » Swing » GridBagLayout
The code generated by the NetBeans GUI editor for GridBagLayout may prove instructive. In the navigator, right click to select GridBagLayout and choose Customize to see an interactive visual guide to the available constraints.
On a side note, you should try Javaspring layout. It was added recently. It is very flexible and is worth trying.
Check "Derek Banas" Java tutorials. His explanation is very good and concise. Look for tutorials 20-28.

Official Java tutorials are ok if you are an expert, but useless for a beginner. But then you don't need them anyway.
I am pleasantly surprised, nobody jumped up with "this is not a "recommend me a tutorial" site!"

I'm looking for recommendations for a simple open source implementation of a Distributed Hash Table in Java to play around with. No fancy features, just for learning purposes, no production functionality needed. It should be simple to set up (e.g. 1 physical machine with n-JVMs) and well documented preferably with some examples, tutorials or starting guides.
Research yields these candidates: FreePastry and OpenChord but I'm not fully convinced they meet my criteria simplicity-wise.
Have you got any experience with these or other implementations? Recommendations?
Thanks & adios
There is TomP2P on Github.
Maybe JDHT will fit the bill. I haven't checked it out myself, but it's written at a university, sometimes that means it's simple and used for teaching. :-)
I have been working on an implementation of Kademlia lately. It's very simple to setup and use and it's well documented. There are several tests written that demonstrate the different functionality as well as a starting guide in the Readme.md file itself.
You can use openkad
I started with free pastry..I've had a great experience with it. It was very simple to set up and run a ring of nodes. I've been mainly using PAST (File storage) and its been quite easy to get running. I'd suggest having a look at the PAST tutorial here. https://trac.freepastry.org/wiki/tut_past
The code is over simplified in my opinion but you say that is all you need so I guess thats ok.

Has anyone found/written any tutorials on the official GWT MVP framework that's found in the GWT 2.1 RC?
Google have updated their large scale web application development series with a sample application and extensive documentation that demonstrates their new MVP support in GWT 2.1 (Model/Activity/Views as they call it now)
Not a tutorial but I wrote one sample that one can use as a skeleton.
http://code.google.com/p/hello-goodbye-mvp/
A promising series of tutorials on GWT 2.1 MVP started with this article:
http://www.over-look.com/site/index.php/documentation/techblog/item/gwt-2-1-tutorial-1-mvp-the-model
This blog shows how to use Activities and Places and provides similiraties with Gmail (what is a place and what is an activity). I suggest you to read the different post and the questions and answers from the comments because they are quite enlightening.
web
Try this. Part 2 of that article has a link to a sample project download.
Also, watch this presentation by Ray Ryan. I highly recommend to download a PDF file with slides, because, for whatever reason, the cameraman decided to focus on Ray, instead of code.
Google has tutorial on Official GWT MVP Framework, visit below link to start/view that tutorial:

I need to start developing using this technology servlets/jsp with tomcat. I need to get up to speed fairly quick. What would you recommend to get up there fairly quick? No 900+ pages manuals. A good tutorial (even a video lectures) with lots of examples would be perfect.
Thanks
Check out simple.souther.us
Hanging out at JavaRanch is a good idea
Getting a Head First Servlet and JSP is worth it
J2EE tutorial is good to go too
I would install Tomcat, and look at all of the included examples. Each example shows a different feature or way of using Tomcat. If you start tomcat up with the defaults, you should be able to go straight to http://localhost:8080/examples to view them.
CoreServlets.com has a good tutorial using Tomcat 6.0:
http://www.coreservlets.com/Apache-Tomcat-Tutorial/
or if you prefer a visual approach then check out this video (wchi additionally introduces Eclipse and WTP into the mix - but it's a good practice to use this to develop simple web applications):
http://www.youtube.com/watch?v=-l0CFxdroTE
I think that the following link will answer not almost all but literally all doubts that you have about servlets and give you a nice flow to study them.
this website is most appropriate since it provides examples as well and is more practical based teacher.
enjoy

There are plenty of Java wiki engines. I'm currently looking for good lightweight wiki , something like the community wiki on Stack Overflow, that can be easily integrated into excising applications.
I personally use JSP Wiki. It's lightweight, easy to use, and obviously uses Java. You just drop it in an application server, make some small config changes and you're golden! I set this up as my company's Wiki and it runs just great.
I really like Mylyn WikiText: besides offering UI elements like an Eclipse editor, it offers API and Ant tasks for working with various wiki formats (Textile, MediaWiki, Confluence, Trac) and exporting to HTML, PDF, and others. It's available in Eclipse Galileo and as a standalone library (see bottom of the page).
Consider FitNesse if this is in any way programming related. It allows you to write tests in the Wiki and have the testing framework update the Wikipages with the results. This allows others than programmers to collaborate on this.

check out GWiki, http://labs.micromata.de/display/gwiki/Home it's great.
