Generating a Self-Signed SSL Certificate

I recently switched some web services to use SSL, and I was surprised that I couldn't find a good non-interactive script to generate the files needed for Jetty and other Java containers. After working my way through writing the script, I have decided to share my approach. This script generates a SSL subdirectory of whatever folder it lives in, and to that directory it adds a password file, certificate and a Java-friendly PKCS12 version of the certificate.

And then I have my Maven build process copy the generated files into the base of my classes directory. The embedded Jetty instance needed an input stream of the PKCS12 file and the contents of the password file to create a SSL connector. Reading from the classpath can be a bit tricky - I should post about that later. From past experience, I think Nginx also requires the certificate file when configuring SSL.

ReactJS, NPM and Maven

I'm just starting to get into working with ReactJS, Facebook's open source rendering framework. My project uses SpringBoot for annotation-driven dependency injection and MVC. I thought it would be great if I could use a bit of ReactJS to enhance the application. If you're looking for a basic conceptual intro, I recommend ReactJS for Stupid People and of course the official documentation  is quite good. In full disclosure, I still have no idea how to do "flux" yet. As an experienced Java backend developer, I'm pretty decent at hacking Maven builds - which is precisely what this blog post is going to be about. First, a word about how React likes to be built. Like many front-end tools, there is a toolkit for the node package manager (NPM). From the command prompt, one might run npm install -g react-tools  which installs the jsx command. The  jsx  command provides the ability to transform JSX syntax into ordinary JavaScript, which is precisely what I want...

Solved: Unable to Locate Spring Namespace Handler

I attempted to run a Spring WebMVC application, and when starting up the application complained that it didn't know how to handle the MVC namespace in my XML configuration. The project runs JDK 7 and Spring 4.0.6 using Maven as the build system. The following is my XML configuration file: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xmlns:mvc="http://www.springframework.org/schema/mvc"        xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc.xsd">          <mvc:annotation-driven/> ...

Parsing HTML with JSoup

The transit demo site I'm building uses data from several websites - such as the Port Authority's press page. Unfortunately, most sites aren't designed for easy parsing; usually data is only available as HTML. So I need to parse HTML to uncover useful information, and if you've ever looked at the source of an average web page, writing a parser from scratch is a challenging task. Enter the jsoup library. This programming interface exposes the structure of a HTML document in a way that can be queried, traversed and even altered by Java programs. I had previously used it to clean out HTML tags from user-submitted content, but recently have been taking advantage of its powerful query engine, which is similar to the way jQuery selectors operate. Let's say I'm parsing some markup that repeats for different stories: I would want to parse this by first finding all of the stories using the <div class="story"> element, and then for each story, quer...
