This document explains the way to setup a portlet.

Entities Involved

PortletCategory – Used to define category for portlets.
PortalPortlet – All the information about a portlet is stored here.
PortletPortletCategory – This associates the portlets with the logical categories.
PortalPage – A portal page. Every Portal Page has a owner associated to it (userLoginId). To move a portlet from one Portal Page to another can be done if
- If the logged in user is the owner of the portal page or
- If the portal page is a system page. (userLoginId="NA")
PortalPageColumn – The number of the columns can be defined for a portal page.
PortalPagePortlet – The portlets that belong to a portal page.
PortalPageAndUserLogin – (View entity PortalPage + UserLoginSecurityGroup) - The portal pages that are accessible to a user if he belongs to certain security group.
PortletAttribute – This defines all the attributes of a portlet. For example, to display a portlet, it needs a roleTypeId (attrName) = PLACING_CUSTOMER (attrName).

How To Setup

Here I am taking an example from OOTB implementation to show how do we setup a portlet.
The reference file here is PartyPortletData.xml Data preparation needs to be done as shown bellow this is all done for viewprofile page in partymgr:

Following is the first portlet with its all the associations and details:
<PortletCategory portletCategoryId="PROFILE" description="Profiles"/>
<PortalPortlet portalPortletId="party"
    portletName="Party Info"
    screenName="Party"
    screenLocation="component://party/widget/partymgr/ProfileScreens.xml"
    description="General information about a person or party group"
    screenshot="/images/portlets/party.png"/>
<PortletPortletCategory portalPortletId="party" portletCategoryId="PROFILE"/>
<PortalPage portalPageId="PartyProfile" sequenceNum="0" portalPageName="Party Profile Portal Page" description="Party profile page using flexible Portal technology" ownerUserLoginId="_NA_"/>
<PortalPageColumn portalPageId="PartyProfile" columnSeqId="00001" columnWidthPercentage="50"/>
<PortalPageColumn portalPageId="PartyProfile" columnSeqId="00002"/><!-- no width in pixels or percent, use the rest of the space available -->
<PortalPagePortlet portalPageId="PartyProfile" portalPortletId="party" portletSeqId="00001" columnSeqId="00001" sequenceNum="0"/>

Screen Setup

Now following code works in the screen to have portlets in action:
Trace the screen "viewprofile" from /party/widget/partymgr/PartyScreens.xml. Here we fetch portal page details to show.

<entity-one value-field="portalPage" entity-name="PortalPage">
    <field-map field-name="portalPageId" value="PartyProfile"/>
</entity-one>
<entity-and entity-name="PortalPageColumn" list="portalPageColumns">
    <field-map field-name="portalPageId" value="PartyProfile"/>
    <order-by field-name="columnSeqId"/>
</entity-and>
<entity-and entity-name="PortalPagePortletView" list="portalPagePortlets">
    <field-map field-name="portalPageId" value="PartyProfile"/>
    <order-by field-name="columnSeqId"/>
    <order-by field-name="sequenceNum"/>
</entity-and>

After this we include generalized showPortalPage.ftl to render the portlets in portal page:
<platform-specific><html><html-template location="component://common/webcommon/portal/showPortalPage.ftl"/></html></platform-specific>
