Example 1 with RenderPortletOutputHandler

use of org.apereo.portal.portlet.rendering.RenderPortletOutputHandler in project uPortal by Jasig.

the class PortletFailureExecutionWorker method renderError.

Example 2 with RenderPortletOutputHandler

use of org.apereo.portal.portlet.rendering.RenderPortletOutputHandler in project uPortal by Jasig.

the class PortletRenderHeaderExecutionWorker method callInternal.

/**
 * Obtain the RENDER_HEADER output. Note that uPortal supports the model of obtaining HTML
 * markup from the portlet, whether from a Spring view or servlet output and inserting it within
 * the HTML HEAD section of the page. uPortal does not support the model where the portlet
 * creates DOM elements to be written to the HEAD section and constructs the HTML output; e.g.
 * the following does NOT work in uPortal:
 *
 * <p>
 *
 * <pre>
 * Element linkElement = response.createElement(HTML.Tag.SCRIPT.toString());
 * linkElement.setAttribute(HTML.Attribute.TYPE.toString(), "text/javascript");
 * linkElement.setAttribute(HTML.Attribute.SRC.toString(), cssUrl);
 * linkElement.setTextContent(" ");
 * response.addProperty(MimeResponse.MARKUP_HEAD_ELEMENT, linkElement);
 * </pre>
 *
 * @see PortletExecutionWorker#callInternal()
