Working with literal notationed objects in angularJs is fine but when the codebase is getting bigger and bigger doing that create problems, specially when you are working with a REST API. Because the Structure of an Object generated after consuming a particular REST api is not defined within the project in the above approach, so […]
What is Dijkstra’s Algorithm Dijkstra’s algorithm is used to determine the shortest path or shortest distance between two nodes in a given graph, Dijkstra’s algorithm comes under the category of pathfinding algorithms and these algorithms are highly used in data transmission over the networks. If I try to make it simple, the page you are […]
Database synching is something we really need when we are having a local database server for development and a remote database for demoing purposes. even though we write ER diagrams by analyzing the customer requirements, naturally requirements are born to change so we have to change our object model as well as the database structure […]
k-means is one of the most widely used Clustering algorithm existing right now, in the algorithm k is a variable which we need to provide and algorithm will divide a given n number of observations into k number of clusters, logic of assigning a cluster to a particular observation is based on the distance between the observation […]
Recently one of my friend who just passed out of the university went to an interview and there the interviewer asked him to write an sorting algorithm without using array length as well as without using for or while loops. Here is the algorithm I came up, there can be various ways you can solve […]

We can use ant to start and stop a Tomcat Server, in your build file you can define these tasks with few other tasks like creating war, deploying war to tomcat. after that by typing a single ant command you will be able to stopTomcat,createWar,deployWar,StartTomcat
By default tomcat does not have any manager accounts, setting up a manager account is important for ant remote deployments 1. open tomcat-users.xml which is located at <Tomcat>/conf/ you will see that by default there is no users, every thing is commented
Jackson and googl’s Gson library are the most leading JSON serializers available for java, in simple words these libraries can convert a given java object directly to its JSON equivalent. In this blog post I’m covering basics usage of Jackson few Jackson annotations creating custom serializer when needed for this tutorial you will be needing jackson-core […]
Recently I came to a situation where I need to generate alpha-numeric string as an Id, with the below constraints 1. It should increment starting from a given string 2. It should first go to all the permutations within the given string length, but if it is still not enough, program should generate the next […]
