Hi Experts,<br />
<br />
WHEN I AM REQUESTING SERVICE URI FROM REST CLIENT.<br />
<br />
how the rest client is generating http error codes.<br />
what will be happen internally<br />
<br />
For example there is a post method<br />
<br />
empid,name,address<br />
in my pojo class all these fields will be mentioned accordingly.<br />
<br />
Now from the restclient when i am passing requestbody by changing empid as EMPID<br />
it will throw 404 Exception.<br />
how it is reading the parameters<br />
<br />
<br />
Thanks,

How the Restclient detecting http error codes

Representational state transfer (REST) is an architectural style that gives a coordinated set of constraints to the design of components in a distributed hypermedia system used to design networked applications. RESTful systems typically communicate over Hypertext Transfer Protocol (HTTP) with the same HTTP verbs (GET, POST, PUT, DELETE, etc.) that web browsers use to retrieve web pages and to send data to remote servers. REST interfaces with external systems using resources identified by Uniform Resource Identifier (URI) that can be operated upon using standard verbs.

REST

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.
