I am trying to expose a simple web resource on JBOSS AS using Spring.
Is it mandatory to configure RESTEasy with Spring in order to the server to serve the requests correctly?
I have already deployed my war file without no configuration in the web.xml and I don't know if the configuration has something to do with RESTEasy integration.
All the documentation found indicates so but I need to be sure if it can't be done without RESTEasy.
If you want to access Spring beans in your REST endpoint classes, then you have to integrate Spring with RestEasy, so that RestEasy is able to find your Spring beans. If you don't have this requirement, then it's not necessary.

I know I could use Apache CXF with Spring by declaring certain CXF beans, but want to know how these framework technically integrates with each other.
Does CXF libraries provide some service provider interface known to Spring, so Spring scans for this, instantiates the service and takes control of it? Or does CXF implement some other standard mechanism for Spring integration? If so, what is this standard?
Or does CXF library expose Spring annotations / bean declarations to participate in the Spring configuration when in the classpath?
Where I can find the exact sequence of how Spring takes control of CXF from having both of these frameworks on classpath and the necessary configuration to both of them running together? Which configuration is scanned in which side, what API's are called by which and so on.
CXF's is the Bus and its default implementation is SpringBusFactory which scans for certain Spring xml bean configuration files. You can find more information in http://cxf.apache.org/docs/cxf-architecture.html#CXFArchitecture-Bus or by looking at the sourcecode: https://github.com/apache/cxf/blob/master/core/src/main/java/org/apache/cxf/bus/spring/SpringBusFactory.java
Spring boot by default uses Tomcat as an Internal Embedded Servlet Container .
It has also got support for Jetty and UnderTow.
I have build a Restful Application using spring boot . But now i need to deploy it on Grizzly (Glassfish) Servlet Container .
How do i embed my application to run on grizzly as spring dosen't have support for the same.
https://github.com/spring-projects/spring-boot/issues/5015.
Please help as i researched a lot on thistopic but i coudnt get any link that shows how to embed a new Servlet Container for our spring boot app that spring dosent have support for.
Thanks
The Grizzly website states that Grizzly's servlet support is incomplete:
This is not a Servlet compliant implementation and as such, not all features exposed by a typical Servlet container are available here.
I haven't seen anywhere that expands on what those missing features are, but there's a good chance that what you're trying to do isn't possible without filling in some gaps in Grizzly's servlet support.
Assuming that it is possible, you need to write Grizzly-specific implementations of Spring Boot's EmbeddedServletContainerFactory and EmbeddedServletContainer interfaces. This is a fairly significant amount of work so, before undertaking it, I would ask yourself what you will gain by being able to use Grizzly as an embedded servlet container versus using Jetty, Tomcat, or Undertow which are already supported out of the box.
If you do decide to tackle this, reading the source code for the existing implementations for Jetty, Tomcat, and Undertow is the best way to learn about what needs to be done:
JettyEmbeddedServletContainer.java
JettyEmbeddedServletContainerFactory.java
TomcatEmbeddedServletContainer.java
TomcatEmbeddedServletContainerFactory.java
UndertowEmbeddedServletContainer.java
UndertowEmbeddedServletContainerFactory.java
As pointed by #Andy there is no support for Spring Boot and Grizzly .
Finally i moved to Spring MVC for the same.
Here is the working repo where i embedd Spring MVC with grizzly.
Hope it helps someone.

There is now a third-party implementation of a Spring Boot starter for Grizzly which has specific implementations of the Spring Boot's EmbeddedServletContainerFactory and EmbeddedServletContainer classes for Grizzly.
Besides that it also offers JSP support through Tomcat's Jasper JSP engine, simply by specifying an additional dependency. You can find the project at GitHub and it is also listed in the Spring Boot starters list.
I have an app that runs a jetty server that registers some ja-rs endpoints by means of jersey handlers. I am using Spring-security-oauth2 but I don't see the way of connecting the context with the jersey dispatcher/filter/servlet.
I found it! I finally found this as the actual clue to know how to work it. I should had ask for Jetty more than Jersey, and spring-security in particular instead of spring-security-oauth2
Spring Security without web.xml
and also
Embedded Jetty doesn't recognise Spring MVC Security

Sorry for not being clear in my question, I am developing a Spring project with the next dependencies
Spring Boot
Spring Data
Mysql
wsdl
In the project I exposed soap Web services with Spring Data for persistence, I have to use RMI for support of application desktop.
I tried the following :
Integrate in the same project Spring and RMI (using RMI Register ) successfully but when I tried use Spring annotations obviously not working.
I'm searching when I found that Spring have support for RMI using XML configuration but I need the configuration in annotations.
My question How to would implement RMI in my project?
I'm using latest version in all dependencies
I need to start developing applications using the Spring framework, and am wondering what tools I need to download to have me up and running.
On the SpringSource website I am seeing all these applications to download and I am wondering, do I really need all this? And what versions should I use, especially for Spring Framework?
Spring Framework
SpringSource dm Server Samples
Spring Security
Spring Web Flow
Spring Web Services
Spring Dynamic Modules
Spring Integration
Spring Batch
Spring.NET
Spring JavaConfig
Spring LDAP
Spring Extensions
Spring IDE
Spring BlazeDS Integration
SpringSource Bundlor
Spring ROO
What other applications do I need to download (eg. Struts, Glassfish, Apache, etc.)?
This depends on what you want to use Spring for. Typically that's Web applications. If so you only need two things:
Spring framework (with minimal dependencies); and
A servlet container (eg Tomcat) or a full-blown application server (eg Glassfish, JBoss).
Everything else is optional. I believe the only required dependency is Apache Commons logging. Depending on what features you use, you may well need more.
If so, here is a [tutorial][1] that creates a barebones Spring MVC project. There are countless others around for that and other topics.
It's entirely possible to use Spring in, say, a Swing application in which case you obviously don't need a servlet container.
All you need from SpringSource is the Spring Framework.
Spring 3.0 is on the way, but for now, use 2.5.6.SEC01, the current production release.
You can get started with a simple servlet container (ie: Tomcat) rather than a full blown application server (eg: JBoss, Glassfish).
The Spring Framework comes bundled with jars for web development - ie: spring-web and spring-webmvc.
See #117535 for a simple example of using Spring MVC.
It mainly dependent on what you need Spring for. Each and every piece of Spring can, actually, be used in separation from the rest. You may use it only for IOC, in this case you don't need, for example, MVC and Servlets, etc...
The easiest way to start is to dowload the main package from http://www.springsource.com/download/community?project=Spring%20Framework
You can use Spring from any IDE
The best way is to use Maven with your project. Basically all you have to do is edit your pom.xml file and tell it that you want to use Spring. Then when you compile your code, Maven will go out and automatically download the Spring libraries you need from their public repository.
Here's an example:
