REST is a set of principles that define how Web standards, such as HTTP and URIs, are supposed to be used. REST is an architectural paradigm. RESTful describes using that paradigm. REST is a style of software architecture for distributed systems such as the World Wide Web. REST facilitates the transaction between web servers by allowing loose coupling between different services. REST-style architectures consist of clients and servers. Clients initiate requests to servers then servers process requests and return appropriate responses.

As described in a dissertation by Roy Fielding, REST is an "architectural style" that basically exploits the existing technology and protocols of the Web. RESTful is typically used to refer to web services implementing such an architecture. REST" is an architectural paradigm. "RESTful" describes using that paradigm. @GET @Path("/getFile") @Produces("application/pdf") public InputStream getFile() throws Exception { FileInputStream fin = null; FileOutputStream fout = null; DataInputStream dis = null; System.out.println("getFile called in server..."); File serverFile = null; System.out.println("getfile called.."); try { serverFile = new File("E:\\Sample2.txt"); fin = new FileInputStream(serverFile); dis = new DataInputStream(fin); fin.close(); // dis.close(); } catch (Exception e) { System.out.println("Exception in server appl..***************"); e.printStackTrace(); } return dis; } In my client application im calling this service as... String clientURL = "http://xxxxxxx:xxxx/RestfullApp02/resources/LoadFile"; Client client = Client.create(); WebResource webResource = client.resource(clientURL); InputStream ob = webResource.path("getFile").get(InputStream.class); But i unable to get the response , it sending 500 error.. like below errror.... com.sun.jersey.api.client.UniformInterfaceException: GET http://myIp:myport/RestfullApp02/resources/LoadFile/getFile returned a response status of 500
