Since we know the fact that REST services can be used with SOAP ones, is there a way to intercept SOAP services using Jax-RS. I got both REST/SOAP services running in my system and I need to have some sort of interceptor to intercept the service calls. I can easily intercept the REST calls using JAX-RS but not the SOAP services.
Has anyone gone through this kind of situation, please let me know.
You can do this by exposing your SOAP web services as Camel end points. Then you can use camel to 'log the request/response as a pre/post processor'. There are lost of articles on the subject- here is an example of exposing your SOAP WS via Camel.

I have a web service that sends a name to a web service called sayHello(), and receives a String "Hello, name".
I want to change the point-to-point connection to something like this:
web service ---> Mule ESB ---> web service
I wonder how can I do that? I've searched for a long time but I didn't find useful document on this topic. Which endpoints should I use?
Thanks.
It depends on the type of webservice you need to expose and consume:
For exposing SOAP based webservices, you can use some strategies,
1) Proxying webservices with Protocol Bridging or WSProxyService
https://docs.mulesoft.com/mule-user-guide/v/3.7/proxying-web-services
2) Proxying webservices with CXF
https://docs.mulesoft.com/mule-user-guide/v/3.7/proxying-web-services-with-cxf
3) Building a webservice with CXF
https://docs.mulesoft.com/mule-user-guide/v/3.7/building-web-services-with-cxf
For exposing RESTful webservices, you should design a RAML and then use the APIKit component
http://raml.org/
https://docs.mulesoft.com/anypoint-platform-for-apis/apikit-tutorial
For consuming SOAP based webservices, you should use the Webservice Consumer component
https://docs.mulesoft.com/mule-user-guide/v/3.7/web-service-consumer
For consuming REST webservices, you should use the HTTP Request Connector :
https://docs.mulesoft.com/mule-user-guide/v/3.7/http-request-connector
So, if you want to expose a SOAP webservice (not a proxy service), that internally consumes a SOAP webservice, you can use:
HTTPListener->CXF->WebserviceConsumer
If you want to expose a webservice proxy you can use the ProtocolBridging or CXF strategy.
If you want to expose a REST webservice, that internally consumes a REST webservice, you can use:
HTTPListener->APIKit->HTTPRequest
And so on..
This describes a scenario that you are trying to fulfill https://docs.mulesoft.com/anypoint-platform-for-apis/proxying-your-api
My Web Service have been implemented in Jersey Framework.
I want to call this web service ( server) from client which I want to implement in restlet framework.
Is it possible ?
Regards,
Nothing stops you from doing that :). Fundamentally, all you do is invoke a HTTP URL by passing some parameters. REST is all about this very basic principal. So under the hood, all the REST client implementations do this. Please go ahead and use whichever REST client you are comfortable with.
I have a client/server application that communicates via SOAP. The server-side application is a Java EE app that exposes web services using JAX-WS. I have a servlet filter setup to perform certain checks before a service is invoked.
This is all working pretty well, except for exception handling. If I throw an exception from the filter, it gets returned to the client as a generic server exception. I need to find a way to propagate a custom exception containing a specific message, so the client can display the message to the user.
Any insight?
A servlet filter isn't really the right tool if you want to send the exception in a SOAP response and I would consider using a JAX-WS handler for the verification of incoming messages instead (JAX-WS handlers are somehow to JAX-WS services what Filters are to Servlets).

JAX-WS Handlers
In addition to support for web
services development, the JAX-WS
framework (the latest Java programming
language API for creating SOAP-based
web services and web service
consumers) also provides a handler
framework. Handlers provide a means
to inspect and manipulate incoming or
outgoing SOAP messages (on both the
client as well as server side). They
act as powerful message interceptors
that can perform an array of functions
such as message transformation,
content filtering, tracking, etc. In
fact, handlers are often used in
runtime environments to implement web
service and SOAP specifications such
as WS-Security, WS-ReliableMessaging,
etc. JAX-WS handlers are similar to
EJB interceptors or servlet filters.
Handlers, like interceptors and
filters, encourage developers to
follow the chain of responsibility
pattern.

I am currently using the jaxws and apache CXF framework to create webservices using the top down approach.
I am using the SOAP interceptors to add remove SOAP header elements, using SAAJ, before the message gets to the container, and the container maps the SOAP action too the java method. I am doing this to create Security Token Services (STS) to facilitate a lite implementation of the SAML2 Profile - converting authentication details into portable identities (SAML Authentication Assertions).
I cannot help think there must be an easier way to do this. Is there a framework that will allow me to manipulate the message with more ease? and if so a tutorial would help.
Many thanks
To change things in SOAP messages you must use SOAP Handlers.
Maybe easier way to do it is changing the way you are securing your web service, if you use a WS-Security way of doing things, our container will work with it fine, and you don't need the handlers anymore.
I have some webservices exposed through xfire and want to have security around those webservice calls. How can I add security without changing anything inside the web services? Basically I want to intercept these webservice calls before it is reaching actual webservice and to authenticate those calls. Please help me

Sounds like a job for Spring Security. It can provide security around an existing non-Spring application without any internal modification.
