In this post, I will discuss how to create a simple Maven multi-module project. In multi-module projects, we have multiple modules to be built using Maven. We have external dependencies as well as internal dependencies between different modules. Let's figure out how we can create multi-modules projects in Maven and how the internal and external dependencies are handled by Maven during the build process?. Technologies used: Maven 3.3.3 JDK 1.6 Simple Structure for Multi-Module Project There are multiple ways to create the structure for multi-module maven projects. It depends on the project requirements, code repository structure, and project lifecycle (need for parent pom release, packaging, etc.). One of the simplest structures is given below: Sample Project - RoketApp In order to understand in a better way, let us create a sample multi-module project - RocketApp , similar to the above structure. RocketApp consist of two module - rocket-core & rocket-ut...

Tricky Java Questions

Interviewers often ask tricky questions to check the candidate knowldege about Java programming language. Sometimes experienced programmers also fail to answer tricky questions. In this post, I have picked few conceptual questions that will helped you to have better understanding of Java language. #### Q-1: what will be output of following code ? ``` public static void main(String[] args) { Integer number1 = 100; Integer number2 = 100; if (number1 == number2) { System.out.println("number1 == number2"); } else { System.out.println("number1 != number2"); } ``` #### Answer: ``` number1 == number2" ``` We have compared the references of two Integers. The result is surprising !!!. This is because of the autoboxing. Java uses IntegerCache to suppor...

How to update existing CCDT file (AMQCLCHL.TAB) for successful MQueue connection

The client channel definition table ( CCDT) file contains the MQ channels definitions and authentication information used by the client program/application to connect to the queue manager. It is a binary file so we cannot modify using any text editor. Change in the channel properties like SSLCIPH, USERID, etc. in Queue manager also required change in the CCDT file. Otherwise, it will break the application MQ connection. From IBM MQ v8.0 onwards we can create and modify the CCDT file on client machines directly. Below are the steps to modify the existing CCDT file. Set the necessary environment properties First set the location of CCDT on the client machine. You can do it using the following environment variables: MQCHLLIB – Specify the directory path where the CCDT file is located. MQCHLTAB – Specify the file name of CCDT (a default name – AMQCLCHL.TAB) #Only path (exclud...
