PortletFaces provides the PortletFacesContext.getThemeDisplay() method at the Java level and also the liferay.themeDisplay EL variable for getting access to the Liferay ThemeDisplay object.

PortletFaces provides the pf:icon Facelet composite component tag that encapsulates an HTML img tag whose src attribute contains a fully qualified URL to an icon image in the current Liferay theme. Additionally, PortletFaces provides the liferay.themeImagesURL and liferay.themeImageURL Facelet composite component tags for gaining access to theme image icons.

Most of the standard JSF HTML component tags render themselves as HTML markup such as <label />, <input />, <span />, etc. and assume the current Liferay theme thanks to the power of CSS. However, the h:messages and h:message tag will not assume the current Liferay theme unless the following JSR 286 standard CSS class names are applied:

<h:messages errorClass="portlet-msg-error" fatalClass="portlet-msg-error"
	infoClass="portlet-msg-info" warnClass="portlet-msg-warn" />
			

As a convenience, PortletFaces provides the pf:messages and pf:message Facelet composite component tags that encapsulate the h:messages and h:message tags respectively, and automatically apply the JSR 286 standard class names as shown above.
