In this blog post, I’m going to explain how you can make use of the Micronaut framework to organize your project code in such a way that you can externalize and modularize some of your @Beans. These beans can be used as “common” and can be shared between several projects.

In this article, we are going to talk about Java’s Service Provider Interface (SPI). We will have a short overview of what the SPI is and describe some cases where we can use it. Then we will give an implementation of an SPI for a practical use case.

Using openssl, the command is... However, I will need to do this often and have written a Java class that handles this and more (my application is mostly .jsp with Tomcat and Apache). When I try run the same command from Java using Runtime.

In this tutorial, we’ll learn how to transform a Java Object to JSON-LD and vice versa. Also learn how to verify the schema of JSON-LD. JSON-LD is a JSON-based format which is used to represent structured data and linked data. Schema of JSON-LD can be found in documentation of schema.org.

This is a Java implementation of the JSON-LD 1.0 specification and the JSON-LD-API 1.0 specification. The Options specified by the JSON-LD API Specification are accessible via the com.github.jsonldjava.core.JsonLdOptions class, and each JsonLdProcessor.

This is going to be a look at my philosophy and views on ActivityPub and why I believe the solutions to ActivityPub criticisms must come from communities. I believe there needs to be a clear way for communities to form and build upon the ActivityPub specification.

Java 16 introduces Records. While this version of records is fantastic, it's currently missing some important features normally found in data classes: a builder and "with"ers. This project is an annotation processor that creates: Hat tip to Benji Weber for the Withers idea.

If you have data for which a digital signature was generated, you can verify the authenticity of the signature. To do so, you need In this example you write a VerSig program to verify the signature generated by the GenSig program.
