Introduction In one-way SSL authentication, the server application shares its public certificate with the client. In a two-way authentication, the client application verifies the identity of the server application, and then the server application verifies the identity of the client application. Sometimes two-way SSL is also known as Mutual Authentication.
In this article, we will be going to learn how to set up the one-way SSL and two-way SSL for MuleSoft applications.

One Way SSL As mentioned above in one way SSL only client verifies the server certificates. At the server end, there will be a Keystore that will hold the private and public certificate of the server whereas, at the client end, there will be a truststore that will hold the public certificate of the server.
Clients will send Hello and request for the resources on the secure HTTPS protocol.
The server will respond with its public certificate (.crt) and send Hello.
The client will verify the server public certificate in its truststore.
The client sends back symmetric session key generated using the server public certificate. The server will decrypt the symmetric session key using its private certificate and send back the encrypted session key to the client for establishing a secure connection.

Below is the flow diagram for oneway SSL

Difference Between HashMap and Treemap

           

HashMap	TreeMap
HashMap can contain one null value	Where as tree map does not contain null value throws runtime exception
HashMap does not maintain insertion order	Where as tree map maintains ascending order.

Adapter vs Decorator vs Facade vs Proxy Design Pattern in Java

There is some striking similarity between Adapter, Decorator, Facade and Proxy design pattern, in the sense that they all use Composition and delegation to solve the problem. Adapter pattern wraps an interface, and delegates call to it. Decorator wraps an object and implement behaviour on top of that, Facade wraps one or more interface to provide a central interface, which is easy to use and Proxy Pattern also wraps Subject and delegates calls to it. Then questions comes, why they are different patterns? What is difference between Adapter, Decorator, Facade or Proxy pattern, if there structure is same. Answer is Intent. Yes, all of these Java design pattern has similar structure and class diagrams but there intents are totally different to each other. Main purpose of Adapter pattern is to convert interfaces. Adapter let's two components working together, which wouldn't be working because of incompatible interfaces. Decorator pattern, adds new functionalities at runtime. It allows you to enrich object, even after it's creation. Facade design pattern neither converts interfaces nor adds new functionality, instead it just provide simpler interfaces. So instead of client directly accessing individual components of a system, it uses facade. Facade design pattern allows client to interact with complex system with much simpler interface and less work. Facade will then call individual components. Proxy pattern is also quite similar to Adapter and Decorator, but it's purpose is to control access of object. Proxy prevents client's to directly accessing object, instead it act as real object and can provide alternate behavior or forward request to original object. Proxy is most versatile pattern of all these, and it can be used in different ways e.g. remote proxy for communicating with remote object, virtual proxy to control access of expensive object, protection proxy to provide access to object based on roles, Caching proxy, which can return cached object etc. In this Java design pattern article, we will try to examine some simila

Logging apache cxf Soap request/response pay load.

Hi,

   In order to log SOAP request and response payload of apache cxf we need to follow below steps.
 
   1. create a  folder structure below under src or classes package
        --WEB-INF
                ---cxf
                 
   2. create a org.apache.cxf file with extension .Logger under cxf folder.
         like org.apache.cxf.Logger. Add a code snippet org.apache.cxf.common.logging.Log4jLogger
        under Logger file.
 
   3. Add below statement in your  log4j properties file.
          log4j.logger.org.apache.cxf=info

  After completing the above steps now the request and response payload will be write into log file.
