title: How to add preference option to the liferay portlet
body: <p>I want to create a portlet where the portlet allow access to the remote application. That is the content of the portlet should be dynamic so for the same reason I want to add one option "Preferences" in the portlet (Where the look and feel and configuration options exists). In that preference page If will give some http url (<a href="http://localhost:8080/Myapp/Mypage" rel="nofollow">http://localhost:8080/Myapp/Mypage</a>) then on click of save button, the URL page should display in the portlet. How can I do that? Note I am going to use same portlet in different pages with different URLs.</p>
