I want the gwt app to call a spring boot rest service with basic authentication which consumes and produces a json object and is deployed on a seperate server from the gwt app.
Any hints on how this can be done ?
There is a library called restygwt to easily define REST calls. I think there is an easy way to set the 'Basic' header.

I am trying to create a microservice using spring boot where it will expose REST service. But inside i also want to consume SOAP service. i have created one SOAP service in spring boot but i also i want to use the same application for my REST calls which i am not able to do. When i am hitting the base url, i can clearly see my SOAP service has been exposed correctly. But when i am hitting to a configured request mapping URI, it is failing to reach. I am very little understanding.. but i need your help to get the idea where i am missing big. Thanks in advance.
Please refer to the below screenshots

Though your question lacks many vital informations, I would like to give it a shot.
How does your application.properties look like? Which spring boot version are you using?
If you are on latest spring boot, you can try adding
server.servlet.context-path=/demo to your /resources/application.properties file. That might be the missing piece here.
I developed a dynamic web project in eclipse java EE ide as index.jsp, when I run it on Tomcat Server7.0 server it says http://localhost:8080/filename/ something. is that what they mean by REST? or do I need Spring to run a REST ?. rest is what that comes in a url, if i provide this url in my browser it opens the file, then why I can't call it as rest service?
Restful is an architectural style that make in disposition through HTTP a number of resources under different formats, usually json, to set or retrive the ressources, simple http operations (PUT, GET, POST, and DELETE. PUT) could be used for that.
I recommend you to use JAX-RS, but here u can see how to work with rest web service with Spring:
Building a RESTful Web Service Spring
I went through http://cxf.apache.org/docs/jax-rs-client-api.html documentation but I am still not sure which type of rest client should be used in what use cases?
Can anyone point out the use cases / constraints with examples that would help me in choosing the right client API.
CXF 3.0 implement the JAXRS 2.0 client API, it makes your code can work with other JAXRS implementation without changing anything.
But if you are still using CXF 2.x, you need to chose between the Proxy Based API and WebClient API.
The Proxy Based API is much like the CXF JAXWS Client API, you can just invoke the service from a Proxy which implement the interface of SEI. It has some shortcomings, you cannot specify the http hears or write a generic client to invoke the different JAXRS services.
With the help of CXF WebClient API, you can invoke the JAXRS services in a normal HTTP client way, which just fill the gap of Proxy Based API.
You can find more information about those clients API here.
I have a requirement from a client which wants to write a wrapper REST web service around a SOAP web service.
I am new to both SOAP and REST. Can anyone please let me know
If we can call SOAP web service inside a REST web service?
If yes, then how to do it in Jersey 2.0?
Thanks in advance.
Yes
There is nothing special about calling a SOAP service from inside a JAX-RS Resouce. Just write a JAX-WS client as described in the Java EE 7 Tutorial.
I am creating a web application in eclipse (via dynamic web project wizard). the Main job of this web app is to call an External web Service's Methods. to accomplish this task should i make an EJB which will call this web service or should i go with creating a Web Service Client. what are the best practices and recommendations.
Keep it simple - just create a web service client. Unless you have reasons for using EJBs (perhaps distributed transactions) you are over-engineering. You can always add this later if you need it.
you can simply use Java Jersey for this. Here goes a clean tutorial
