What are Portals?

Portal = Entry pointCustomizable for the userCan unite several sources of information

Portal API

JavaClass: CustomDataIn package blackboard.portal.externalJavadoc available in SDK

Portal API

To get the CustomData for a module, use getModuleData(context)

CustomData data = CustomData.getModuleData(pageContext);

String text = data.getValue(“body.lunchMenu”);

String text = data.getValue(“body.type”);

Portal API

Can also save module global properties

CustomData data = CustomData.getModuleData(pageContext);String text = data.setValue(“body.lunchMenu”, “Roast Turkey”);String text = data.setValue(“body.type”,”Entrée”);data.save();

Portal API

Similar Methods exist to set user specific data

CustomData data = CustomData.getModulePersonalizationData(pageContext);String text = data.setValue(“userpref.display”, “ALL”);data.save();

Packaging the Module Type

Put it in a System Extension PackageJSPs in /module directory

<module-type ext-ref="smpl-module" title="Sample Plug-in Module Type" uicreatable="true">

<jsp-dir>module</jsp-dir> <jsp> <view>view.jsp</view> <edit>edit.jsp</edit> <admin>admin.jsp</admin> </jsp></module-type>

Creating a Module

Can specify a module type already in the system or in the same installation package

Many modules can be created using the Bb supplied types

Could leverage types that become available in the community

Entries in bb-manifest.xml file:– module– channel

Creating a Module

Module is packaged a standard Integration Agent Package

bb-manifest.xml– module– channel

Specifying a Module

Module Manifest Entry:<module type="portal/channel" isadmin="true" useraddable="true" isdeletable="true" title="Sample Channel Module"> <description>Sample channel module. This module accesses the RSS channel installed with this plug-in.</description> <ExtraInfo> <property key="channel.id" type="String">smpl-gamenews</property> </ExtraInfo></module>

Specifying a Module

Channel Manifest Entry (Module Def):<module type="portal/channel" isadmin="true" useraddable="true" isdeletable="true" title="Sample Channel Module"> <description>Sample channel module. This module accesses the RSS channel installed with this plug-in.</description> <ExtraInfo> <property key="channel.id" type="String">smpl-gamenews</property> </ExtraInfo></module>

Specifying a Module

Channel Manifest Entry (Channel Def):<rss-channel ext-ref="gamenews" title="Game News"><data-url> <http://www.palminfocenter.com/feed.xml </data-url></rss-channel>

Specifying a Module

Can also optionally specify Portal Roles

<module-groups> <module-group id="Student"/></module-groups>
