You need to put a sharing reference for "com.sap.km.application" in your portalapp.xml. Check out the following portalapp.xml. You can either put
"com.sap.km.application" or "knowledgemanagement".
<application>
  <application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb,com.sap.km.application"/>
  </application-config>
  <components>
    <component name="links_tree">
      <component-config>
        <property name="ClassName" value="com.ust.kmtree.display"/>
        <property name="SecurityZone" value="com.ust.kmtree/high_safety"/>
      </component-config>
      <component-profile>
        <property name="path" value="/documents/prakash"/>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
  </components>
  <services/>
</application>
