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 can't seem to find one that's been updated recently. If none, is there a good Java library for doing the necessary signature verification, base64 decoding, etc operations needed to interact with Facebook's API?
UPDATE: I'm using Spring Social Facebook to aid in working with Facebook. It doesn't handle everything and isn't perfect, but the best library out there for Java. Looking forward to the ongoing progress from Spring. I asked a couple questions in their forum and responses were informative and super quick.
I just started using RestFB. I looked at Spring first, but this seems like RestFB has a gentler learning curve. I'll update if it works for me.
You can check facebook's official android SDK which is written in Java:
https://github.com/facebook/facebook-android-sdk
all basic things like verification, decoding, etc are there, maybe android-related stuff is not what you need but I guess it is relatively trivial to extract it from there.
hope this helps
i think the semi-official java SDK is the spring social one:
http://www.springsource.org/spring-social
but i wrote a Java wrapper for Facebook's REST GRAPH API
(http calls to the graph api, and translations from json objects to java classes..)
you can check it out here:
https://github.com/itzikrou/fishbowl
hope it's usefull..
https://github.com/roundrop/facebook4j looks nice but haven't yet used it.
For example, the search API look straightforward:
ResponseList<User> results = facebook.searchUsers("mark");
ResponseList<Post> results = facebook.searchPosts("watermelon");
Go to developers.facebook.com , there u will get all API's releated to facebook..also manual regarding how to use them...

are there any good examples or tutorials on how best to structure an android applications anywhere?
am new to java and android and i've built winforms apps using passive and supervising controller variants of model view presenter and model view controller in asp.net but not really seen any examples or code on android that use these sorts of patterns.
how do people structure decent size android apps out there in the wild. are there any best practices or should i be sticking rigidly to official android documentation.
Try with the following two examples. I've found them useful in understanding how MVP might apply to Android applications.

http://web.archive.org/web/20130525044856/http://jamespeckham.com/Blog/10-11-21/MVP_on_Android.aspx
Also Mosby implements an MVP pattern plus other things, but it is modular enough so that you can use only the MVP part and forget about the rest.
There is also a nice blog post covering the motivations and choices of this library
Check out the Android Developers page. There you will find the answers to all of your questions. And MVC is already present in Android. Check out this question. The videos here can explain what you're looking for.
I created an application to manage my expenses. It is built using MVP pattern. I have explained it in this post.

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.
http://fitnesse.org/FitNesse.UserGuide.OneMinuteDescription
check out GWiki, http://labs.micromata.de/display/gwiki/Home it's great.

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
