Error while creating IViews using collaboration API

Question

Hi
I have created one Dynpage portal component, in that i would like to utilize collaboration API.
I am keep on getting errors like "<b>The compilation unit directly references the missing type ...."</b>"
import com.sapportals.htmlb.page.DynPage;
import com.sapportals.htmlb.page.PageException;
import com.sapportals.portal.htmlb.page.PageProcessorComponent;
import com.sap.ip.collaboration.room.api.IRooms;
import com.sapportals.portal.prt.runtime.PortalRuntime;
import com.sapportals.htmlb.*;
import com.sapportals.htmlb.enum.*;
public class Sample extends PageProcessorComponent {
  public DynPage getPage() {
    return new SampleDynPage();
  public static class SampleDynPage extends DynPage
     IRooms roomsAPI = (IRooms)PortalRuntime.getRuntimeResources().getService(IRooms.PORTAL_SERVICE_ID);
Initialization code executed once per user.
I have included the following jar files:
bc.rf.framework_api.jar
coll.shared.extension_api.jar
coll.shared.roomobject_api.jar
coll.shared.types_api.jar
com.sap.security.api.ep5.jar
and also i have included com.sap.netweaver.coll.shared in portal.xml as servicesreference
Experts can you please help in the above problem

HI,
You have to add the following jars apart from the jars you have mentioned
1. kmc.util.core_api.jar
2. umapi.jar
To find jar files
==================
Download and install the JAR Finder. how to is mentioned in this <a href="https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2951">Weblog</a>. see what jar is required by copying the com.sap.ip.BaseException  from the error "compilation unit references................." and put the "BaseException" in the jar finder and search. from the given options select the correct jar "com.sap.ip.BaseException" right click and add to the project. You can add all the jars required by this method.
Portalapp.xml
==============
<application-config>
    <property name="SharingReference" value="com.sap.portal.htmlb"/>
    <property name="ServicesReference" value="com.sap.netweaver.coll.shared"/>
  </application-config>
HI,
use the BaseException etc the errors you get in NWDS to search for the jar. paste the BaseException and search in jarfinder.
