Does WS02 support Jersey services ? I am able to set up proxy services in WS02 for Axis2, would like to do the same with Jersey. Is there any documentations that talk about setting Jersey proxy services in WSo2 ?
I guess when you say Jersey services - you meant to say RESTful services - JAX-RS (JSR 311). Yes, WSO2 ESB can route traffic to RESTful services as well as you can expose backend services in RESTful manner with the API element in ESB.

I have to invoke a couple of rest web service from my spring boot application. I am planning to use the Camel to configure the flow and other EIP use cases. Some of the endpoints are using oAuth2 authentication. I am planning to use the Spring oAuthResttempalte. All the examples on the internet are either using restlet, CXF or camel-http.

I am not able to find a single example with just spring resttemplate. Did anyone implement Camel Rest consumer using Spring Resttemplate?
Some of the Examples on the internet use a jetty server to consume a rest endpoint. Why do you need a jetty server for simple rest consumer?

I'm not aware of that and it's unlikely to found something in that direction because Camel already have bult-in components to consume rest endpoints.

I believe that jetty was used as a consumer not a producer endpoint. So you won't need the "server". Or maybe you saw an example using jetty acting as a server to serve an OAuth endpoint?
If you excuse my approach, I'd suggest to remain with Camel HTTP/Rest capabilities to consume REST APIs using OAuth. I've found this example on Gist:
from("direct:authService").tracing()
.setHeader(Exchange.HTTP_PATH)
.simple("<auth service context>/oauth2/token")
.setHeader("CamelHttpMethod")
.simple("POST")
.setHeader("Content-Type")
.simple("application/x-www-form-urlencoded")
.setHeader("Accept")
.simple("application/json")
.setBody()
.constant("grant_type=client_credentials&client_id=<client id>&client_secret=<client sec>")
.to("https4://<remote auth service url>")
.convertBodyTo(String.class)
.log("response from API: " + body())
.choice()
.when().simple("${header.CamelHttpResponseCode} == 200")
.unmarshal().json(JsonLibrary.Jackson, AccessResponseToken.class)
.setHeader("jwt").simple("${body.access_token}")
.to("direct:<some direct route>")
.otherwise()
.log("Not Authenticated!!!");
If you want to stick into OAuthRestTemplate you may implement a Processor or a bean to wrap those calls and return to your route the authorization token.
I've created a spring boot based service and like to deploy it to existing mule API platform, then I realize there are some challenges I need to face by myself such as, service discovery and policy management.
To be specific, I want to know if there is any way to manage policy for spring boot service from mule API manager? Since there is no agent that mule service has.
The straight forward way is to proxy your custom API by generating a proxy in the Anypoint API Manager.
Deploy that proxy application on a Mule server in CloudHub or on a runtime on-premise.
Then you have your Spring Boot Application API under control and can apply policies, see analytics, etc.

I new to SOAP web service. In my project there is a requirement where I need to consume the SOAP web service in spring MVC. I tried search in google I am not getting simple example to integrate the SOAP services with spring MVC.
I have few other question as well.
What is JAXB? As per my understanding the JAXB is used for marshalling and unmarshalling the objects from service.
2.Whether I can use both restful web service and SOAP web service together in same spring mvc application?
3.What is different between Spring-WS and JAX-WS?
What is JAXB? As per my understanding the JAXB is used for marshalling
and unmarshalling the objects ?
Yes, JAXB is a framework which can be used to convert Java object into an XML file (stream) and vice versa.
Java Object to an XML file conversion is called marshalling and the opposite is unmarshalling.
This technique will be useful when two applications are exchanging the business data using XML.
2.Whether I can use both restful web service and SOAP web service together in same spring mvc application ?
Yes, you can use both together with in the same project as per your business requirements.
For example, assume that your application (project) might need some data from two external sources i.e., external system1 (assume that it exposes it's endpoints in SOAP) and
external system2 (assume that it exposes it's endpoints in REST), your application has to interact with both of those to exchange the data.
Similarly your application might need to expose few services in REST and few services in SOAP (assume that the other system can consume only SOAP), it is all about agreeing between different systems on data exchanging formats.
3.What is the difference between Spring-WS and JAX-WS ?
JAX-WS is a specification & implementation built into JDK for consuming/producing SOAP services.
Spring-WS is a Spring API for consuming/producing SOAP services.
There are two types of SOAP frameworks available for the development of projects:
Compliant to JAX-WS - like Apache CXF, Apache Axis2, etc..
Non compliant to JAX-WS - Spring-WS
You can look at here for the list of web service frameworks
I'm developing a REST service using JAX-RS and Java 8 and Tomcat 8.I already configuration using {springconfig}.xml. I want to know how to use Spring in Jax-rs web service for controller.I'm looking for answer.
I am trying to work on a PoC to replace an IBM WESB Proxy mediation (Exposed as a web service, Receives the soap request, Invokes different other Web Services based on the Soap Header passed in the request).
These web services are built using JAX-RPC and Spring framework running in WAS 7 container.
Is it possible to use Camel for this usecase? I don't want to migrate the underlying web services to CXF or SpringWS yet.
Does Camel have any URI's to solve this purpose? (like a web service adapter to call other non-CXF/non-SpringWS web services)
Any help is very much appreciated. Thanks.
First thing - If it is a RPC /ENCODED web service then you CANNOT call it even with cxf.There are ways that you can modify the rpc wsdl to use doc/literal but I would not suggest using that approach.
The simplest way to do this if you do not want to use cxf component or spring-ws is to create a java bean to invoke the Axis web service using the generated stubs.
