Today, i donwloaded Spring Framework 4.0.6 latest version but unable to locate the jar files, and i donwloaded eclipse plugin for spring too, here i find nothing and looking for a way to include these jar files into eclipse, here is a pic.
Some tutorials website refers that it contains into lib folder but i can't see it, please help!
It sounds like you have a number of hurdles to overcome:
How to use Eclipse
How to manage Java dependencies
How to use Spring
I'm not sure what your level of experience is, but you may wish to consider using Spring Tool Suite as your IDE - it's based on Eclipse with additonal plugins to aid Spring development.
I also urge you to use Maven or Gradle to manage your dependencies. The Spring documentation provides the configuration for adding the dependencies in both. I'd recommend Maven as a starting point as it is easy to use with little knowledge and is well suited to small, standard projects. Gradle is worth a look once you are comfortable with Maven.
Work though the Guides - I'd start with 'Building Java Projects with Maven'.
Edit
Maven is a dependency management and build tool that favours convention over configuration. Dependency management is powerful in that you can declare a dependency on Spring Core, for example, and it will download all the related dependencies for you.
Gradle performs similar functions to Maven but also provides the ability to use scripting. Gradle is seen by many as Maven's predecessor and has been adopted by Spring over Maven.
In my opinion Maven is easier for you at this stage.

I just started developing a project in Spring MVC and i want to know how important Maven is.
The following are the key features of Maven :
Simple project setup that follows best practices - get a new project or module started in seconds
Consistent usage across all projects - means no ramp-up time for new developers coming onto a project
Superior dependency management including automatic updating, dependency closures (also known as transitive dependencies)
Able to easily work with multiple projects at the same time
A large and growing repository of libraries and metadata to use out of the box, and arrangements in place with the largest Open Source projects for real-time availability of their latest releases
6.Extensible, with the ability to easily write plugins in Java or scripting languages
Instant access to new features with little or no extra configuration
Ant tasks for dependency management and deployment outside of Maven
Model based builds: Maven is able to build any number of projects into predefined output types such as a JAR, WAR, or distribution based on metadata about the project, without the need to do any scripting in most cases.
Coherent site of project information: Using the same metadata as for the build process, Maven is able to generate a web site or PDF including any documentation you care to add, and adds to that standard reports about the state of development of the project. Examples of this information can be seen at the bottom of the left-hand navigation of this site under the "Project Information" and "Project Reports" submenus.
Release management and distribution publication: Without much additional configuration, Maven will integrate with your source control system (such as Subversion or Git) and manage the release of a project based on a certain tag. It can also publish this to a distribution location for use by other projects. Maven is able to publish individual outputs such as a JAR, an archive including other dependencies and documentation, or as a source distribution.
Dependency management: Maven encourages the use of a central repository of JARs and other dependencies. Maven comes with a mechanism that your project's clients can use to download any JARs required for building your project from a central JAR repository much like Perl's CPAN. This allows users of Maven to reuse JARs across projects and encourages communication between projects to ensure that backward compatibility issues are dealt with.
Getting started with maven only takes about 10 minutes. Reasons why you should learn maven:
It helps you manage your dependencies very easily so you don't need to add jars to your project classpath manually
You can run unit tests
Has over 20 useful plugins which you can use. Plugins make up lifecycles like test, package which make your work more efficient
You can use it to build your project
The most important thing about it at the beginning is that you don't need to worry about setting up your project by adding dependencies, maven does it for you automatically.
Read this spring guide for building with maven
Any other guides in this section for spring boot has the same mechanism
I'm making my first Java EE project and can't figure how to test my EJB. I've read that Arquillian is really useful to do integration tests, but it seems like using it without Maven is difficult. Could someone tell me if there is a way to use it or a tutorial?
Are you using any sort of dependency management tool, eg Ivy? I really recommend using one, since it makes things much easier.
That said, Arquillian does not use Maven itself, so you can use it without Maven. You will just have to figure out which dependencies you need. You can either work it out by just looking at the Maven POM files, or you could start with a sample Maven based setup and use the maven-dependency-plugin to export the libraries you need. See also https://gist.github.com/mojavelinux/2363038.
Personally I would recommend to just use a dependency management tool, be it Maven or Ivy.
I have been trying to start a simple Spring project as a part of my study. From the tutorials (they are about a year old resources i am refering), it seems the Spring related libraries were easily available online then. But now; I was unable to get something like a "spring_ver_no.zip" from the spring source site. It is having options to download a tool suite which is about 350 MBs large.
Can you please guide me if that download is the way to setup a Spring development environment?If not what is the way to set up a simple Spring environment in eclipse.
Thanks

You should use a dependency management tool like Gradle or Maven, and let this tool download the libraries for you. See the quick start for how to include Spring in your dependencies. If you still want to download the jar files and add them manually to your project, then download them directly from the Maven central repository: http://search.maven.org/#search|ga|1|g%3A%22org.springframework%22
Spring is, for a long time, splitted in several modules. You have to download all the modules you need.
Spring is using Maven lately. You should use it too. Maven is a build tool and dependency manager that will ease your life.
What is the best practice when it comes to managing dependencies in a small java project? Small meaning one Eclipse Java project. I have 4 different third-party jars that I have added to the Eclipse build path. I have had experience with Maven, but for this small scope, it doesn't seem like it would fit. I have read about Gradle, but have not tried it. What's the best way to approach this?
I recommend Apache IvyIDE.
http://ant.apache.org/ivy/ivyde/
It allows you to manage your dependencies declared in an ivy.xml in your Java Eclipse projects.
Perhaps the reason I stalled learning Java until now is because I HATE how Java handles external libraries. I'm stuck keeping them in one place, adding them individually, fixing problems with versioning and every time I move/rename them, and copying and writing the classpath over and over each time I release a Java application.
There has to be an elegant solution to all of this. I keep all of my libraries (regardless of task, platform, or other) in their own little folder inside a "lib" folder in my development folder, kind of like this:
Dev
-lib
+JS-jQuery
+Flex-Degrafa
-Java-Xerces
+Xerces-1.2.3
+More libraries
I can use either Netbeans or Eclipse for Java dev, but none of them provide a very streamlined (and not to mention idiot-proof) way of managing all of these.
A nudge in the right direction or an online article/tutorial on this would be greatly appreciated.
You can either use Ant + Ivy or Maven to manage your library dependencies.
If it is only dependency management you're after and you're happy with the rest of your build process, I would use Ivy, as it can unobtrusively manage your dependencies, leaving your existing build process intact. There is a plugin for Eclipse called IvyIDE that contributes your dependencies via a classpath container.
Maven 2 has a steeper learning curve but provides a much richer set of functionality for building your projects and Eclipse integration through m2eclipse or IAM.
Personally I use Maven as I have a large number of projects to work with and Maven is particularly suited to efficient development across lots of projects.
Have a look at the introductory documentation to see what works for you.
Ivy Tutorial
Maven Getting Started Guide
Netbeans 6.7.1's Maven support is quite good and comes out of the box with the IDE.
The Eclipse addon was frustrating enough that I gave Netbeans another try.
A third choice besides ChssPly76's options is to use Ant with the Maven Ant Tasks. I don't know if I'd call any of these solutions particularly "elegant," but they do spare you the need to manage your own lib/ directory and classpath variables.
If you're working on Linux you can install Java libraries with APT or RPM.
Otherwise, I normally check precompiled JARs into a lib directory in my project's version control repository and make sure the names of the JAR files include full version information. E.g. lib/foo-1.5.6.jar, not lib/foo.jar.
To avoid having to manually set the classpath before running your app, you can set the classpath in the Manifests of the JARs themselves to define the dependencies of each JAR file. The JVM will follow all the dependencies when loading classes.
Maven is often more trouble than it's worth, but the ability to open a maven project directly into IDEs such as IntelliJ is excellent. For example, IntelliJ will download all dependencies and have them available without having to run a build first, or an mvn command and then a project refresh. It also isn't necessary to re-generate the project every time a dependency is added. I work with a number of Eclipse developers who switched to IntelliJ for this alone.
However, one shortfall of Maven is that many libraries (or versions of libraries) are not available on public repositories. Therefore it is often necessary to set up a local repository such as archiva. In ant, it would just be a matter of adding it to the lib directory in the repository.
Maven can also attack when you need to do something that maven doesn't directly support via a plugin. What would normally be a few lines of ant can often turn into a morning's worth of work.
Finally, buildr is an excellent way of using Maven's dependency management and plugins, while also supporting ad-hoc tasks.
