I want to learn EJB3. Anyone could suggest some good tutorial website for it?

Java EE Documentation & Tutorials
Creating an Enterprise Application with EJB 3.1
Building Secure Enterprise Beans in Java EE
JavaBeat - EJB 3.0 articles
Enterprise Beans (The Java EE 6 Tutorial)

I read the O'Reilly book Enterprise JavaBeans 3.0. It covers almost the entire EJB3 spec, and is very well written. The book has two parts: The first part (most of the book) covers core EJB3 as it applies to any implementation or application server. The second part is a "workbook" of how to actually implement various bits under JBoss.

Very good tutorial
http://download.oracle.com/javaee/5/tutorial/doc/gfirp.html

Following two are Best book I ever had read for EJB 3.0
1) Apress Pro EJB 3 is best book with it tutorials, Also You can find some link inside which will give you source code described in Book
2) This is for the Beginers of EJB 3 and it is having best description with Examples

I have been looking for some good MVC2 cheatsheets to help a new team of .NET developers get used to some of the basics of MVC as a pattern and also MVC2 as a microsoft framework.
I found a few examples for MVC1 in relation to the HTML helpers but nothing that including the new features of MVC2.
Where can I find some cheat sheets for MVC2?
RedGate has a good MVC poster you can download, but this doesn't go into great depth on the objects and properties in MVC.
Alternatively there are a few MVC 1 posters here.

Red Gate has a great MVC Request Handling poster
There are several MVC posters available here (there are at leave 4 MVC ones):

My client has a busy traffic site with a big amount of pages, ASP.NET's built-in cache solutions is good, but it only stores content into the memory. Since the site has a big amount of pages, so I think disk caching would be a better idea. But after searching I didn't find a solution, any suggestions?
There is the ConcurrentCache project on codeplex which has support for 4 caching modes:
Memory
Files
Compressed
Auto
I can't say much about the project as I only just found it myself but I'm giving it a go right now.
ASP.NET 4.0 allows you to write your own cache provider. Scott Gu's blog discusses the details.
.Net 4 lets you write your own using OutputCacheProvider and there may be some examples out there. No doubt someone will roll out an open source project around this when .Net 4 gets more traction.
There was one in ASP.Net 2.0 Betas apparently, but it got removed in the RTM. You can still find references to the web.config DiskCache parameter.
This gist is based on Scott Mitchell's article.
DiskCache.NET is a library that lets you cache data in a file.

I just started a new project and my boss wants us to change IDE from NetBeans to Eclipse, RichFaces to Flex. I have never worked with Eclipse and Flex before.
Today I tried to make hello word with it on Eclipse but had no luck.
Can some one post or give me link to Flex->BlazeDS->Pojo on Eclipse for Beginner (Dummy) :D
Thanks
Update: Forgot to mention that I'm using glassfish but I don't think it will make any problems
This seems like a pretty good tutorial: Set up blazeds on tomcat with eclipse for FLEX. Heres the POJO they use:
package test;
public class tester {
public String getData() {
return "hi";
}
}
It doesn't address BlazeDS or Pojo, but Adobe has an excellent series of free training videos for Flex and Flex Builder.
I recommend this book:Beginning Java Flex, it got me up an running in a couple of days and is a pretty good intro to flex, blazeds, spring and hibernate, and an easy read. It walks you through some examples for each section.

anyone know of some well written (but not too complex) ASP.NET web applications/websites that i could download from code.google.com or something? i just want to peek at how some other projects look to get some ideas for how to structure my project before it goes live. many thanks.
Check here : Microsoft Official ASP.NET Starter Kits
Take a look at The Code Project. Lots of good stuff there.
CodePlex has a lot of the microsoft asp.net open source projects, also a good place to start
I would recommend using ASP.NET MVC 2 for new web development.
You can find proper 'real-world' sample application called NerdDinner and 185-page PDF walkthrough 'how-each-line-was-written on Code Plex. Nerd Dinner has many nice features, like intergration with maps or OpenID.

I am an ASP.Net developer looking to expand my dope skillz to the wonderful world of Java. Strangely, there seem to be a ton of "ASP.Net for the JSP Developer" tutorials, but very few (no?) "JSP for the ASP.Net Developer" tutorials. Just simple things like the difference between the file structures and layout, what webserver to use and how to configure it, etc... A thousand tiny differences add up to a frustrating experience that, no doubt, a single good tutorial could easily answer.
So... anyone know of a good tutorial? Or, short of that, what is the best "getting started" with JSP tutorial?
I do not know any tutorials for that neither, but I know a little of both worlds (jsp and asp.net) and I recommend you two ways:
1st. If you just want to know the syntax differences, It might be a good try take a first look at this JSP Overview by Sun and you will automatically map main differences (I do not recommend you to go this way because both platforms do not differ only on its syntax)
2nd. If you are going to develop Java Web Applications, you should take a first look J2EE Tutorial (specially in Part II) and also some MVC frameworks (Struts, Spring Web MVC) and some 'different MVC approaches' JSF.
JSP is a front-end technology, it is not a good practice to put business logic and/or complex code on it.
Hope it helps.
