JSP tags for standard portlets

The standard portlet API defines several tags that can be used in portlet JSPs to get access to the portlet request and response and to generate URLs. To make these tags available in a JSP, the following directive is required at the beginning of the JSP:

   <%@ taglib uri="http://java.sun.com/portlet" prefix="portlet"%>

For more information on these tags, see the Java Portlet Specification.

WebSphere Portal Express provides an additional tag for use in standard portlets. To make these tags available in a JSP, the following directive is required:

   <%@ taglib uri="/WEB-INF/tld/ibm-portlet-ext.tld" prefix="portletExt" %>

The following is a brief description of the extension to the JSR 168 portlet JSP tag library.

<portletAPI:portalRenderURL attribute="value">

Creates a URL to pages or portlets on pages. Attributes are as follows:

contentNode="id|name"

Indicates the ID or unique name of the page. The name or ID of the content node is also used to specify the page where the portlet can be found.

portletWindow="id|name"

Indicates the ID or unique name of the control that holds the portlet. Must be used in combination with the attribute contentNode (above) to identify the page where the portlet is located.

portletMode="view|help|edit|configure"

For URLs to a portlet indicated by portletWindow, this attribute sets the portlet mode. This parameter is ignored if the attribute portletWindow (above) is not set.

windowState="maximized|minimized|normal"

In the case of a portlet, this attribute indicates the state of the portlet window when it is displayed. If the portlet state is not specified, the page is shown with the previous state of the portlet. This parameter is ignored if the attribute portletWindow is not set.

portalState="solo|normal"

Indicates whether the specified portlet window is rendered normally or solo, that is without a theme. This parameter is ignored if the attribute portletWindow is not set.

locale="locale"

Specifies the locale with which subsequent portal page requests are rendered. This attribute is optional.

var ="name"

Specifies the name of a scripting variable that is exposed in the body of the tag. This attribute is optional. The variable exposes an object that implements the interface com.ibm.portal.DisposableURL that can be used to stream the URL to the output.

<portalAPI:urlParam name="parameter_name" value="parameter_value">

Use this tag to add custom parameters of your choice to the parent portalRenderURL. Parameters are added to the portalRenderURL as render parameters of the specified portlet window. Parameters are ignored if the enclosing portlalRenderURL does not specify the attribute portletWindow. Specify attributes as follows:

name

Required. Indicates the name of the parameter.

value

Required. Indicates the value of the parameter.

<portletAPI:bidi dir="rtl|ltr" />

This tag is used to support text for bidirectional languages. Bidirectional languages are those which are typically read from right to left except when left-to-right text strings are displayed (for example, URLs, code samples, or directory and file names).

dir

Indicates the normal direction of text in the language.

• For dir="rtl", the tag content is written only if the client's locale belongs to a bidirectional language. This is the default setting if dir is not specified.
• For dir="ltr", the tag content is written only if the client's locale does not belong to a bidirectional language.

locale

The tag content is written only if the language belongs to the bidirectional languages defined in LocalizerService.properties .

You can also use JSTL tags as described in Generating output.
