In this I’ll discuss a uncommonly used but useful technique of accessing variables and methods which have been declared as private in the JVM, using the Apache Commons Lang library to work around the restriction. The description from the project page reads: The standard Java libraries fail to provide enough methods for manipulation of its core classes. Apache Commons Lang provides these extra methods. A couple weeks ago I was working on a project that required parsing some CQL statements.
- I tried Python out a while ago, but stopped trying it to learn it after some major frustrations. Maybe I didn’t dig deep enough into it. I found the documentation hard to read, and the module layout seemed a little random at times. For some reason I found executing an external process and getting the results to be a little convoluted. (Since then I’ve learned to use popen(..).communicate()) I ended up messing with other languages to try to find one that suits my tastes, like Erlang and D.
- I’m going to go through the steps necessary to install and start using Solr. I’ve always been interested in trying out Lucene, but I never felt like dealing with writing my own wrapper around the classes. Solr simplifies this by creating a fully working search engine as a web service. Let’s get started. You’ll need to check to see if Java is up to date. Run the below to find out.
