How to Generate a Deployable REST CXF3 Application from a Swagger-Contract – Johannes Fiala
This talk will show how you can use Swagger-Codegen to generate a complete REST application using Apache CXF3 based on a Swagger contract and deploy it to application servers.
Features in the generated server stub include:
* Automatic operation validation using @Valid
* Using transparent gzipping of requests
First I’ll demo how to generate the applications & how they work in the container (Tomcat + Jboss EAP), showing how the features work there.
The talk will continue how this is done using Mustache-templates in Swagger-Codegen and how additional features can be added to the generator (e.g. adding forced Gzip-support, enhancing test cases, add additional configuration files, etc.).
Additionally the Swagger toolchain will be shown during the talk (Swagger UI, Swagger Editor, Swagger2Markup to generate PDFs).
A Deep Text Analysis System Based on OpenNLP – Boris Galitsky
Although current big data systems for text processing can handle vast amount of textual data, they mostly perform keyword level or compositional semantic – level analyses, which limits their functionality and applications. We present an OpenNLP-based system leveraging a broad range of linguistic technologies for search, recommendation, content generation, sentiment, chat bots and social data analysis. We will learn how to leverage linguistic analysis features such as parts-of-speech, parse trees, parse tree-based relevance, discourse analysis, learning of discourse trees and tree kernel learning. We explore how to combine the best of both worlds: big data performance and linguistic style depth of analysis.
Apache Commons Crypto: Another Wheel of Apache Commons – Xianda Ke
Apache Commons Crypto is a cross-platform cryptographic library optimized with AES-NI and hardware random number generator. With the benefits of hardware acceleration and the optimized native implementation, this library outperformed JCE by an order of magnitude. Java developers can use this handy library to get strong and high performance AES encryption/decryption. This presentation will introduce the origin of Apache Commons CRYPTO, the recent improvements in commons crypto community, how CRYPTO accelerates data encryption, and the future plan of Apache Commons Crypto.
Apache Commons – Beyond StringUtils – Benedikt Ritter
Apache Commons is an Apache project focused on all aspects of reusable Java components. The Commons Lang component provides the well known StringUtils class. But there is more to Apache Commons then just StringUtils. In this presentation, Benedikt Ritter will give an overview over the Apache Commons project followed by some examples for using selected Apache Commons components.
Diversity, When Not Playing Life on Easy – Nick Burch
Diversity and inclusion are becoming hot topics within our open source communities and industry, but for those of us “playing life on easy”, the subject and impact can be harder to “get”.
Like many people who used to play life on easy, I’ve had some blind spots around diversity and inclusion. I only discovered these through working on projects, communities and support at the ASF, and by moving to a new country!
Now it is my mission to help others see the light, learn for themselves, and through that build better open source communities. I’ll be sharing what I learnt, giving resources, and specific takeaway actions.
