Very recently, I showed you one of the probably easiest ways, to host your very own Java-based web-service. Remember, we added providedCompile group: ‘javax.servlet’, name: ‘javax.servlet-api’, version: ‘4.0.1’ to the build.gradle file, implemented a WebServlet, and finally dropped a war file into Tomcat’s webapps directory. I know, you’ll have a hard time finding paying customers […]
Java

This is a quick demo, showing how to create a Java web-service in just a few minutes. I’m assuming you have Java and Tomcat already installed on you computer and use IntelliJ as your IDE, and gradle as your build-automation system. The simple task is to create a web-service that can answer if a provided […]
Configuring multiple SSL certificates for a single Tomcat connector

Sometimes you may want the same Tomcat instance to respond to requests for more than just one hostname. For HTTP this can easily be accomplished, by mapping those hostnames to the same IP address, using the tools provided by your registrar. Supporting HTTPS for multiple hosts is more involved since the SSL certificates need to […]
Installing an SSL Certificate on Tomcat

If you have Tomcat installed on your Mac or Linux computer, like I have shown here and here, you may sooner or later want to serve content not only through HTTP, but also securely through HTTPS. Instead of going the self-signed certificate route, where the certificate is signed with its own private key, I’m describing […]
Serverless compute with Java, on AWS Lambda

Serverless computing is a cloud computing execution model, in which the cloud provider dynamically manages the allocation of machine resources. Serverless computing allows running applications and services, without thinking much about servers, runtime resources, or scaling issues. A very simple serverless computing application is intended to be used as a template project, a model, or starting […]
