I quite didnt get the difference between a regular web service implemented either through spring or axis versus Remoting.
If my question is not at all related, I am just confused between spring web services vs spring remoting. When to go for remoting and when to go with a web service.
Appreciate your answer
Spring Web Services is a dedicated Spring Project (using Spring's own Web Service technology), whereas Spring Remoting is a common approach of integrating different third party remoting technologies.
Spring-WS is always contract-first, while Spring Remoting is often code-first.
Your choice of using Spring remoting or web services depends on whether you want to use SOAP or not.
All Spring services should start life as interface-based POJO services, of course. That way you can worry only about implementation and interface; remote access can be an afterthought that way.
Once your Spring POJO service is tested and running, you can choose between a myriad of remoting choices: EJB (RMI-based; Java-only clients), HTTP (any client that can create an HTTP client), web services (SOAP and WSDL), etc. Your choice depends on the types of clients you anticipate and the wire protocol you'd like to use.

Right now I'm working in WebApi (trainee developer), and have good knowledge in webapi . But , I don't know anything about WebServices.
My Questions are :
1.What is WebServices?
2.What is the Use of WebServices?
3.Instead of WebServices why we are using WebApi.
4.Where we can use WebServices?
5.At a time We Can use both Webservices and WebApis?
Exposing the Existing Function on the network
A web service is a unit of managed code that can be remotely invoked using HTTP. That is, it can be activated using HTTP requests. Web services allow you to expose the functionality of your existing code over the network. Once it is exposed on the network, other applications can use the functionality of your program.
Interoperability
Web services allow various applications to talk to each other and share data and services among themselves. Other applications can also use the web services. For example, a VB or .NET application can talk to Java web services and vice versa. Web services are used to make the application platform and technology independent.
Standardized Protocol
Web services use standardized industry standard protocol for the communication. All the four layers (Service Transport, XML Messaging, Service Description, and Service Discovery layers) use well-defined protocols in the web services protocol stack. This standardization of protocol stack gives the business many advantages such as a wide range of choices, reduction in the cost due to competition, and increase in the quality.
Low Cost Communication
Web services use SOAP over HTTP protocol, so you can use your existing low-cost internet for implementing web services. This solution is much less costly compared to proprietary solutions like EDI/B2B. Besides SOAP over HTTP, web services can also be implemented on other reliable transport mechanisms like FTP

can someone help me telling what is RESTful and difference with `web Service'?
i tried to search but i get confused between it and web service can anyone help ?
It's name clearly state its meaning that services provided on the web are called a web service
web service has two type REST API and SOAP API
RESTful Web Services are basically REST Architecture based Web Services. In REST Architecture everything is a resource. RESTful web services are light weight, highly scalable and maintainable and are very commonly used to create APIs for web-based applications.
SOAP (Simple Object Access Protocol) is a messaging protocol that allows programs that run on disparate operating systems (such as Windows and Linux) to communicate using Hypertext Transfer Protocol (HTTP) and its Extensible Markup Language (XML).
RESTful is one kind of web service. Another kind is SOAP. I think comment in this link will help you

our problems:
a sets of existing applications (recruiting, purchasing, payroll etc..) communicate outside through various ways (email, pdf, csv file, webservices etc)
a new ERP system we gona use(SAP or Agresso) communicates the outside through web services
we need integrate the existing systems with the ERP system, and apply some rules
my questions:
can we do the job by only using CXF?
is CXF a subset of camel
or perhaps to achieve what we want, we have to combine those two?
also Mule doesn't give a specific price for the cost, anyone had experience with MuleSoft?
thanks for time!
The comment by BMW is very true.
However to answer you a little more closely.
CXF is a services framework. It allows you to create SOAP, REST and even CORBA services. So yes it can help you create and consume web services.
CXF is a component used inside Camel, CXF is not a subset of camel. Camel will allow you to provide and consume web services using CXF.
Camel is a EIP(Enterprise Integration Pattern) framework which allows you to do things such as route a file to a web service. Or expose a SOAP service that talks to JMS queues etc. I know Camel also has a SAP component.
Thus Camel orchestrates the various components into routes that allows various systems to integrate.
In short you will use Camel with the CXF and other components to resolve your problems.
I have not used Mule yet but I can tell you this. You can host your Camel routes on Apache Karaf and create your own light weight "ESB" so no need to use Mule ESB.
Another alternative would be Fuse ESB and also Servicemix. THey are also capable of hosting Camel route.
I currently have several camel routes that expose web services and consume various data from files, rss feeds etc hosted on Karaf and it works like a charm.
I have two Spring applications. One of them manages data storage (backend), the other communicates with users (frontend). Now I need to connect these two applications with ESB (Probably Fuse ESB) using web services (so probably CXF binding components). Could you explain to me how to achieve this functionality step by step?
I have Service interface and its implementation on backend Spring application.
Thanks for replies
Any Messaging protocol (JMS, AMQP, TCP etc.) would allow you to connect two apps that run in different JVMs together.
Have you look at Spring Integration project? You really don't need ESB for that.
I'm investigating integrating a 3rd party web application with PeopleSoft via web services. I'm not that familiar with PeopleSoft. After some initial investigation, it appears that in order to expose any PeopleSoft functionality as web services, you have to do some considerable configuration in the Integration Broker component of the PeopleTools module. It seems that you can either define internal PeopleSoft services with "service operations" and related "handlers" or you can create a PeopleSoft service for an existing "Component Interface." Then, you have to expose that PeopleSoft service as a web service.
Are there any standard, default, out-of-the-box web services available for a PeopleSoft system, or do you always need to go through the steps of defining them in the Integration Broker?
After looking at a system like Salesforce, which has a standard web services API, it seems like there might be something similar for PeopleSoft, but I'm not finding it. Am I on the right track in thinking that the Integration Broker is the only way to go, or am I just not aware of some standard web services API that exposes basic PeopleSoft functionaity as web services?
Integration Broker (IB) is what you need to expose business logic from peoplesoft and consume it with your 3rd party tool, or to consume a webservice from your tool in peoplesoft.
There are some out of the box messages, but most of them are made to have different PIA (PeopleSoft Internet Architecture) communicate.
Be aware, IB components were almost complemently remixed in peopletools version 8.47. So it's important to give your tool's version when talking about IB.
Never heard about a standalone API for implementing web services, outside of the IB framework. IB will use dedicated class to handle sending and reception of your messages. You mention it as the handler. And if a component interface need to be used it will be done throughout this class.
Integration broker is used to setup the basic configurations that will be used in exposing and using web services. this includes making nodes and its routing available for other system to use.

There are many web services available in peoplesoft. you can alsi expose any componemnt as a web services by executing very simple steps.

Custom web services can also be build.
