Basic MVC portlet

First of all, let's use the knowledge base admin portlet as an example that requires portlet development in the Plugins SDK. This section will use the knowledge base project, as mentioned in the previous section.

Project structure

As mentioned earlier, we will first create the folder, either by executing the Ant target or by manually using knowledge-base-portlet under the folder $PLUGINS-SDK-HOME/portlets. Under the folder, you will see the docroot folder and the build.xml file. For fast development, you can add the XML file knowledge-base-portlet.xml with the following lines.

<Context path="knowledge-base" docBase="$PLUGINS_SDK_HOME/portlets/knowledge-base-portlet/docroot"
/>

Under the folder docroot, you will see the subfolders css, js, and WEB-INF. In addition to the default folders and files generated by the default template, we're going to create a folder named icons and a file under the folder icons named kb-admin.png for the knowledge base admin portlet icon...
