This document provides an introduction to JavaEE 8 and discusses different technologies for making remote procedure calls including CORBA, RMI, SOAP, and REST. It lists the advantages of each technology such as SOAP using HTTP and being readable by humans. The document also provides example URLs to test SOAP and REST calls and discusses serialization frameworks for removing overhead compared to protocols like HTTP.

20. 1. CORBA (Common Object Request Broker Architecture)
a. Hard to use but all language
2. RMI : Remote Method Invocation
a. Simple but Java to Java
b. Internet Inter-Orb Protocol (IIOP) and No HTTP
3. SOAP : Simple Object Access Protocol
a. HTTP base and All Language
b. Human Readable not binary
c. Top-Down : WSDL to Code (First Contract)
d. Button-up : Code to WSDL (Last Contract) (Auto-Generate contract by Application Servers )
4. REST : Representational state transfer
a. Contactless
b. XML , JSON , String
5. Serialization Framework : Java serialization , Google Protocol Buffer , Apache Avro , Apache Thrift
a. Competition of Compression
b. Remove Overhead like HTTP
