title: Can Liferay portlets get parameters?
body: <p>I am having trouble understanding the concept of portlets in a CMS.</p>
  
  <p>Let's say I write a weather portlet to display current temperature.  I build it, package it in a war, deploy the war in Liferay.</p>
  
  <p>Now I created a page, and I want to create 2 instances of the portlet I wrote.  I want to display the weather in Seattle and the weather in Miami.</p>
  
  <p>Can I do this?  How do I pass the portlet a parameter to tell it which city to display?</p>
