I am trying to follow the basic tutorial for Spring MVC but got lost at creating a new project in Eclipse.
It seems to me that most tutorials assume you know how to create a Spring Project in Eclipse.
Any advice on where to get started or tutorials which explain how to set up Eclipse would be appreciated.
You want to create a "Dynamic Web Project". Follow the steps here: Spring MVC Tutorial with Eclipse and Tomcat.
Also, here is the Eclipse documentation for Dynamic Web Projects: http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.wst.webtools.doc.user/topics/ccwebprj.html
Download Spring STS (SpringSource Tool Suite) and choose Spring Template Project from the Dashboard. This is the easiest way to get a preconfigured spring mvc project, ready to go.
You don't necessarily have to create a Spring project. Almost all Java web applications have he same project structure. In almost every project I create, I automatically add these source folder:
src/main/java
src/main/resources
src/test/java
src/test/resources
src/main/webapp*
src/main/webapp isn't actually a source folder. The web.xml file under src/main/webapp/WEB-INF will allow you to run your java application on any Java enabled web server (Tomcat, Jetty, etc.). I typically add the Jetty Plugin to my POM (assuming you use Maven), and launch the web app in development using mvn clean jetty:run.
This is the easiest way :
step 1) install Spring Tool Suite (STS) for eclipse (version 3.7.0RELEASE or above)
To do this you can go to Help >> eclipse market place , then type Spring Tool suite in search box.
step 2) now go to file >> new >> spring project as shown in the image below
step 3)now choose the template as "spring MVC Project" and give a name to your project on the top as shown below ( I named it 'SpringProject')
step 4)now give a base package name like this
and that is . The project will be created in a few minutes and Now you can right click on it and run on server.
step 1: create a new "Dynamic Web Project" in eclipse.
step 2: right click on the created project.
step 3: click on "configure" option.
step 4: click on "convert to maven project".

I install Spring Toolsuite.
I go to New -> Import Getting Started project.
I choose the 'Building a RESTful Web Service' one. Download only the 'complete' project, select maven and not to open the site.
Now what on earth to I have to do to launch it? Right-click on the project, run as, run on server, shows 'The selection cannot be run on any server'.
I have gone through loads of posts trying to find out what else I can do, done maven clean, maven install, changed the JRE Environment, nothing works.
Running a maven clean or maven install will only update the dependencies of the project (for instance, bring in Spring and its child dependencies, loggers, etc. specified in the pom.xml file).
To run the project right click on the class with the #SpringBootApplication
annotation (it will likely be the one with a main method in it, that's the one you want!). Then select 'Run as->Java Application'.
First a disclaimer. This answer applies to most of the guides. But there may be some to which it doesn't apply, because there's such a diversity of guides available.
Assuming you are trying a 'typical' guide which does something in the context of a web-app... then read on.
The reason that you can not run a guide with "Run On Server" is because of spring-boot adheres to the slogan of "Make Jar not War". The guide sample code are not things you deploy on a server (i.e war) but are standalone Java apps (i.e. jar) which contain their own embedded servlet container (if they need one). That means running them is really quite simple. Just find the 'main' method/class in the guide and use Eclipse "Run As >> Java Application".
There's also a convenient alias in STS called "Run As >> Spring Boot App" which does pretty much the same thing but gives you a few extra bells and whistles in the launch configuration editor.
Also... you don't really have to go look for the main method yourself because the "Run As >> Spring Boot App" knows how to find it in most cases. So clicking project and "Run As >> Spring Boot App" should do the trick.
I started to work on a Spring project from scratch and while I was trying to add a new Spring bean configuration file, I just don't see it there. The project structure and the selection wizard is as following,
Figure: No Spring section here in the selection wizard
Figure: project structure
How to add a bean configuration file in the project ? I tried to get a template and add in the project. However, I don't see the different tabs (such as, mvc, context etc ) in the file page. The maven dependencies are fine and it's dynamic web project. I also tried with maven-archetype-webapp as starting point of the project.
Help > Eclipse market
Type spring and search
Find Spring IDE Roo Support and click install
Accept terms and click finish
Restart Eclipse
File > New > Others > Spring > Spring Bean configuration file
1.Help > Eclipse market
2.Type spring and search
3.Find Spring Tools 3 Add-On for Spring Tools 4 and click install
4.Accept terms and click finish
5.Restart Eclipse
6.File > New > Others > Spring > Spring Bean configuration file
Go the Eclipse MarketPlace and search STS there
Install Spring Tool Suit
Then go to the window and select open perspective now you will be
able to see spring perspective there.
After this right click on the src/main/resources
Click on new and select other and search for spring configuration
file
Now you will see configuration xml file select it and name it with
xml extension .
Now you will be good to go.
I have modified the Web content folder & then did the Clean project followed by build project. But still there is no change in project.
I am using tomcat server 7 & JRE1.7.
What is the best way to build a java dynamic web project? How to ensure each & every file of the project gets re-build?
I cannot create a comment on this question so have to put it up as an answer..
Java dynamic web project is not building
What kind of build tool are you using? i.e Maven, Gradle, Ant

Tomcat is there to deploy your web project, so if your build is failing you will not be able to deploy it successfully to your tomcat server. Maybe you could provide us with some sort of error message?

Don't think you will find any "best way", but there's several options out there you can use. Fast google search for build tool
Maven
Gradle
Ant
This is just a few.
I'm new to Java EE development and I heard that If I have to learn the Java EE then the Spring MVC is best choice to learn and get Command of.
After downloading STS 3.6 bundle I'm having some troubles/issues in creating Maven Project. My STEPS are
1- Create new project
2- Error Dialog
It appears that you either don't have Maven installed, or your IDE is not aware of the installation. For the former problem, have a look here. For the latter problem, view this page for IDE you are using:
Eclipse
I would also like to recommend to get started with Spring using the Spring Tool Suite by using Spring Boot and the guides at http://spring.io/guides. You can import those guides directly into STS and start from there.
I also face with this thing too, but I found a solution that just update Maven project by right click on project -> Maven-> Update Project... or (Alt+F5) then check on force to update as image below :
It works perfect for me.
NOTE** internet connection is required
I have created project using Spring Tool Suite IDE, with below navigation.
New -> Spring Starter Project
But outcome was always simple maven M2 project with error symbol.
After project build completion I have updated maven project with option "Force Update of Snapshots/Release".
It turned my project M2 project into M2S Project
Thanks
So I downloaded a trial of idea ultimate, and I want to get spring mvc going with tomcat.
So I setup a new project, configured it to use sun jdk.
I chose a spring application, and it created and downloaded the following:
I don't see any spring-mvc libraries, are they included in there or do I have to do something about that?
Can someone outline what I have to do to get this to build like a spring mvc web application?
I find that the best way to start a new IDEA project is to use the Maven. This allows you to easily build your project without launching the IDE, automatically maintaining all libraries for you.
"Create project from scratch", then select "Maven module" in the next screen. Click on "Create from archetype" and select the "maven-archetype-webapp". This will give you a basic Maven layout which builds a simple WAR file.
Now to add the Spring libraries, open the Maven build file - pom.xml - and insert a new dependency on the Spring MVC framework:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>
From here, you can follow the Spring MVC reference documentation - add the Dispatcher Servlet and Context Listener to web.xml, a Spring XML context and so on.
Something else you might find useful is the Maven Jetty plugin. Once configured, you can run your app by simply typing "mvn jetty:run" at the command prompt (or launching it from within the IDE). Maven will fetch all that's required and deploy the app for you, no need for an external app server setup for quick testing.
I'm not sure if your setup would be identical to mine, but when I downloaded spring-framework-2.5.6 there were jar files named spring-web.jar, spring-webmvc.jar, etc. in the \dist\modules subfolders. The tutorial indicated at least spring-webmvc.jar should be in your WEB-INF/lib folder.
This tutorial optionally used eclipse, but might be helpful anyways, especially getting started:
http://static.springsource.org/docs/Spring-MVC-step-by-step/
I think there are specific JARs for the Spring MVC stuff. Basically when you download the latest Spring Framework and you extract the zip you need to go to the dist folder and add the org.springframework.web.jar and org.springframework.web.servlet.jar/org.springframework.portlet.jar to your project. I'm pretty sure that the servlet/portlet jars will have your MVC specific classes.
