I was recently asked about Maven in relation to Liferay.  Although we don't have any official support for Maven.  Others have made it work with Liferay.

An old co-worker turn me on to this.  I haven't tried it, but he has and loves it.  Hope it helps you in your development.

Creating Liferay portlet with liferay-maven-sdk

With Liferay 5.1, we introduced a new Mail Portlet.  Here are instructions on how to add it

Start by getting to the "Plugins Installer".  You'll see that the Mail Portlet is one of the options.

Select the latest version of the Mail Portlet and click "Install".

The Mail Portlet will start to install and you will see a message that it has installed successfully.

Add it to a page

You'll see that your Tomcat console has the Mail Portlet install logs.

Start using it!

With Liferay 5.1, we introduced a new Chat Portlet.  Here are instructions on how to add it

Start by getting to the "Plugins Installer".  You'll see that the Chat Portlet is one of the options.

Select the latest version of the Chat Portlet and click "Install".

The Chat Portlet will start to install and you will see a message that it has installed successfully.

You'll see that your Tomcat console has the Chat Portlet install logs.

Once you goto another page, you'll see the portlet at the bottom.

UPDATE (2/20/2009) - These instructions apply to versions 4.1.X, 4.2.X, 4.3.X, 4.4..X, 5.0.X & 5.1.X)

Read my post on "How to get Liferay running in Windows XP Pro" for reference.
