This very long chapter covered a cornucopia of topics. First, we went through all of the options which can be customized in your portal-ext.properties file, exhaustively. This serves as a reference section for the file, so you can quickly find documentation for any property you might encounter.
Next, we took a good, long look at plugin management. Every aspect of plugin management was covered, including plugin types, installing plugins from a repository, installing plugins manually, troubleshooting, creating your own plugin repository, and more.
After this, we covered how to configure Liferay's web services in a secure way so that you can access the back end services you need. We also saw how to access web services that your own developers have created with Liferay's Service Builder utility.
Combined with the preceding chapters, the information you've gained so far gives you the ability to competently install and configure a website which runs on Liferay. Next, we'll take a look at some of the ways you can configure Liferay for the enterprise.
