Register the Managed bean in the faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config>
    <managed-bean-name>breadCrumbBean</managed-bean-name>
    <managed-bean-class>org.openntf.breadcrumb.BreadCrumbSessionFacade</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>
  <!--AUTOGEN-START-BUILDER: Automatically generated by IBM Lotus Domino Designer. Do not modify.-->
  <!--AUTOGEN-END-BUILDER: End of automatically generated section-->
</faces-config>

Define the breadCrum in a custom control and add this control to the ApplicationLayout:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core" xmlns:xe="http://www.ibm.com/xsp/coreex">
	<xp:panel>
		<xe:breadCrumbs id="breadCrumbs">
			<xe:this.treeNodes>
				<xe:beanTreeNode nodeBean="breadCrumbBean"></xe:beanTreeNode>
			</xe:this.treeNodes>
	  </xe:breadCrumbs>
	</xp:panel>
</xp:view>


On Each Page do in the beforeRenderResponse Event:
<xp:this.beforeRenderResponse>
 <![CDATA[#{javascript://add the current Page to the breadCrumbBean
    var strBreadCrumbLabel = "The Title of this Page in the BreadCrumb";
    breadCrumbBean.addEntry(""+context.getUrl().getPath(), ""+context.getUrl().getQueryString(), strBreadCrumbLabel);
  }]]>
</xp:this.beforeRenderResponse>

If your Page is a ROOT Page, witch means, that your page should reset the BreadCrumbPath call
    breadCrumbBean.reset()
in the beforRenderResponse Event
