I have Eclipse Kepler installed and working properly on Mac OSX. I'd like to install Spring in order to design, write, deploy a RESTful web service.
I see a plethora of components listed on the update site, and little guidance on what I do/don't need in order to just get started.
Do I need :
SpringSource DM Server Tools?
Spring IDE Core Developer Resources?
Web Flow?
If you have Eclipse installed then just follow the tutorial: Building a RESTful Web Service
http://spring.io/guides/gs/rest-service/
It provides details of the Maven/Gradle configuration that you need which will ensure that the correct dependencies are imported.
Note that it makes use of Spring Boot, which in turn will import dependencies required by Spring MVC. You don't need Spring-WS for REST web services. Spring-WS is for building SOAP web services.

I want a barebone template project for a webapp implemented using spring boot (frontend + backend APIs - DB)
I referred this VS Code's doc for working with Java. It worked fine but it is not a complete webapp.
Thanks in advance!
Vaadin Flow is a GUI framework for web apps driven through Spring Boot. (Alternatively, you can base your Vaadin app on Jakarta EE or plain Jakarta Servlet.)
A customized project template can be generated from their "Start building" web page.
You can manage your Vaadin project with either Maven or Gradle.
If you want to generate an app with spring boot + angular/reactjs/vuejs I think that the best solution by far at this moment is JHipster.
I'm new to WEB SOA applications and i have several questions about how to implements this architecture.
I would like to make a SOA based application involving multiple services using spring restfull api.
I'm aware of how to build each service itself.
i've already made a maven based project exposing a restful service using spring boot and secured it using spring security... my problem is to implement several services:
I don't know if i have to make a project for each one or there's a better solution... i want them to communicate through XML/Json so they won't be in same project in my point of view.
All secured by same service which makes use of spring security, i don't know how to link between the security service and the other ones. i don't want to write same security config classes on each project and then the user would be asked for sign in each time he accesses one of the services.
Share some resources which are used by all most services such as domain model classes, since i don't want to copy paste them (make duplicates), if i would change anything i would have to make changes in all services ... horrible :/
Thanks in advance.
1- Secure them all (the entire application) using one service which
make use of spring security and which will be asked for whenever a
client access one of the services.
This link will help you : https://www.youtube.com/watch?v=3s2lSD50-JI
2- Share some resources which are used by all most services such as
domain model classes.
Here it is about how to organize your project in your IDE or in your architecture. Using packages, shared libraries, shared projects or maven modules can help you.
3- Deploy all services inside one " application container ".
Your IDE or Maven should be able to help you deploy you application in a container. In the case of Spring Boot, there is an embedded Tomcat server that can run your application. Or if you have your Tomcat stand alone installation, you can deploy it by your self.
Reading you post, I guess your are new in Spring Boot development. The learning path I can suggest is the following (in my point of view) :
N-Tier Pattern for application architecture, and the purpose of the layers
The architecture of the Web and HTTP protocol
SOA and REST Services
Maven to build and compile your projects
Spring Boot, in mostly moderns architectures used to implement Backends my exposing REST Services
You can find by Googling tones of well explained documentations and blogs concerning those subjects.
I have developed a web service using spring mvc and hibernate. Currently I couldn't find a solution to add a module to the running web service without terminating it. My intention is to develop the web service as modules and plug modules in runtime. In .Net the solution is developing the program using MEF (Managed Extensibility Framework) the DLL's. I developed some solutions using OSGI framework but I found some practicability issues existing. Please help me to find an applicable solution for the scenario.
deepening of your plan. this is possible with OSGI by registering the new modules as Services and tracking all services in the Framework's service registry by using ServiceTracker
You can deploy the external module as a another app onto the container/server. And leverage JNDI for resource sharing. https://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html
I want to run and deploy a java rest API code on Bluemix. This is more to understand the Devops capabilities in conjunction with API management.
I tried to use this: http://www.codingpedia.org/ama/tutorial-rest-api-design-and-implementation-in-java-with-jersey-and-spring/
But could not push it to Bluemix. May I get some support?
Update:
When I push it to Bluemix, I get an error saying it could not find appropriate runtime.
Reading your comments you are searching for some pointers to create a starter Java REST application (possibly integrating a delivery pipeline).
You can start creating an application on Bluemix using the Liberty for Java runtime. Then you can, from your application dashboard, click on "Add Git" to create a Git repository on IBM Bluemix DevOps Services (IDS). Now you have your starter application running on Bluemix and its code hosted on IDS. You can edit the code directly on the Web IDE of IDS (clicking on "Edit Code") and from there push the new versions of the applcation on Bluemix or you can clone the repository on your local environment (for example using the Eclipse Tools for Bluemix) and deploy directly from your machine to Bluemix.
Using the first option you will be able to quickly setup a delivery pipeline using the "Build & Deploy" button, and use the DevOps capabilities of IDS. The Build & Deploy feature, also known as the pipeline, automates the continuous deployment of your projects. In a project's pipeline, sequences of stages retrieve input and run jobs, such as builds, tests, and deployments.
To add REST capabilities to the sample application you can for example use JAX-RS 2.0. Take a look here.
Javaee jax-rs REST API starter
Use my java REST API starter for bluemix. This uses javaee + jax-rs + swagger
Just fork it, run pom.xml to generate war and push the war file to bluemix. Works like a charm

Spring boot REST API starter for bluemix
if you want a spring boot REST API starter, you can use the following boilerplate. This is a netflix eureka client but you can ignore eureka annotations. The REST API will work seamlessly anyway
https://github.com/sanketsw/Netflix_Eureka_Client_Hello_World
Another cleaner springboot REST API starter is here: https://github.com/sanketsw/SpringBoot_REST_API
I am new to Spring MVC and Web Services. I want to create SOAP services using Spring MVC, Maven and deploy it in weblogic. I want it from scratch. I know this platform is not to ask this type of question but I did not get response in other discussion forum. Please give me some reference link here so that I can go through that.
This has everything you need to get started: http://spring.io/guides/gs/producing-web-service/
