It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. This article explains about how to communicate with Redis using Java client Jedis.
RESTEasy is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is a fully certified and portable implementation of the JAX-RS 2.1 specification, a JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol. It is licensed under the Apache 2.0 license.
RESTEasy is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It comprises of frameworks for mock, embeddable server, rest client, proxy servers, logging and so on.In this article, we will walk-through ETag implementation and show the behaviour related to ETag done by rest easy framework. Example is developed using RESTEasy 3.7 and deployed in tomcat as RESTEasy framework is portable.
The Apache OpenNLP library is a machine learning based toolkit for the processing of natural language text. OpenNLP also includes entropy and perceptron based machine learning. . It contains several components for natural language processing pipeline like sentence detector, tokenizer, name finder, document categorizer, part-of-speech tagger, chunker, parser, co-reference resolution.
RESTEasy is JAX-RS 2.1 compliant framework for developing rest applications. It is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is a fully certified and portable implementation of the JAX-RS 2.1 specification, a JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol.
Undertow is a high performing web server which can be used for both blocking and non-blocking tasks. It is extermely flexible as application can assemble the parts in whatever way it would make sense. It also supports Servlet 4.0, JSR-356 compliant web socket implementation. Undertow is licensed under Apache License, Version 2.0.
I could see many many students posting this question in many forums, I want to contribute to open source but How to contribute? There are many ways to do that. I have listed a few and I hope it might be useful.
In our work there will be situation where we need to resize the image, generate thumbnails and so on. Users need to have little bit of image processing knowledge to achieve it. We have Java ImageIO APIs to achieve these functionalities. As said, we need to be aware of or spend time in learning these APIs. To help us, Thumbnailator library provides easy fluent style API and generates thumbnail in simple three lines of code.
Apache OpenNLP is a library for natural language processing using machine learning. In this article, we will explore document/text classification by training with sample data and then execute to get its results. We will use plain training model as one example and then training using Navie Bayes Algorithm.
Spring Boot is a microservice-based Java framework used to create web application. WebSocket API is an advanced technology that provides full-duplex communication channels over a single TCP connection. This article explains about how to implement WebSocket using Spring Boot.
Light 4j is a fast, lightweight and cloud-native microservices framework. In this article, we will see what and how hybrid framework works and integrate with RDMS databases like MySQL, also built in option of CORS handler for in-flight request.
Traditionally Programmers used ODBC, JDBC, ADO etc to access database. Developers need to write SQL queries, process the result set and convert the data in the form of objects (Data model). I think most programmers would typically write a function to convert the object to query and result set to object. To overcome these difficulties, ORM provides a mechanism to directly use objects and interact with the database.
Redis is an in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. This blog covers the advanced concepts like cluster, publish and subscribe, pipeling concepts of Redis using Jedis Java library.
Exonum is an extensible open source blockchain framework for building private blockchains which offers outstanding performance, data security, as well as fault tolerance. The framework does not include any business logic, instead, you can develop and add the services that meet your specific needs. Exonum can be used to build various solutions from a document registry to a DevOps facilitation system.

We knew that Apace Spark- the most famous parallel computing model or processing the massive data set is written in Scala programming language. The Apace foundation offered a tool to support the Python in Spark which was named PySpark. The PySpark allows us to use RDDs in Python programming language through a library called Py4j. This article provides basic introduction about PySpark, RDD, MLib, Broadcase and Accumulator.
fd is a fast, simple, and user-friendly tool that simply performs faster than find. It isn't meant to be a replacement for find, but rather a slightly faster alternative that is easier to use. Let us explore fd command completely in this article.
Failure is often the catalyst for success. You need to make mistakes to truly learn and grow as a tech worker. Sometimes, you don’t need to make the mistakes to learn. Learning from other’s mistakes can be just as informative and productive. Paying attention to what others have done can help you avoid the same kind of failure. Here are a few common mistakes that authors make that lead to the failure of open-source software projects.
Students ask this question frequently steps or methodology to learn from open source projects. There is no single answer or steps available. I listed the steps which i follow and i hope this will help for few.
MongoDB is a popular and widely used open source NoSQL database. MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution is quite possible. It is licensed under Server Side Public License. Recently they moved to Server Side Public License, before that MongoDB was released under AGPL. This article will provide basic example to connect and work with MongoDB using Java.
