java.lang.ClassCastException: class com.sapportals.portal.pcd.gl.PcdGlContext incompatible with interface com.sap.portal.pcm.admin.IAdminBase

Hi,

I am working on a portal application that personalize's iView property via APIs. The code snippet I am using is as follows:

import java.util.Hashtable;
import com.sap.portal.directory.Constants;
import com.sap.portal.pcm.admin.IAdminBase;
import com.sap.portal.pcm.admin.IAttributeSet;
import com.sap.portal.pcm.admin.PcmConstants;
import com.sapportals.portal.pcd.gl.IPcdContext;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(Context.SECURITY_PRINCIPAL, user);
env.put(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_ADMINISTRATION);
IPcdContext pcdContext = (IPcdContext) new com.sapportals.portal.prt.jndisupport.InitialContext(env).lookup("");
IAdminBase adminBase = (IAdminBase)pcdContext.lookup(path_to_iView);
IAttributeSet attrSet = (IAttributeSet)adminBase.getImplementation(IAdminBase.ATTRIBUTE_SET);
attrSet.putAttribute("com.sap.portal.pcm.Title", Locale.ENGLISH ,title);
attrSet.save();

I have added the following JARs specific to the above code:

com.sap.portal.pcm.admin.apiservice_api.jar

gl_api.jar

prtjndisupport.jar

tc~epbc~pcm~adminapi~java.jar

In SharingReference of portalapp.xml I have added the entries com.sap.portal.pcd.glservice, com.sap.portal.pcm.admin.apiservice, com.sap.portal.ivs.connectorservice, com.sap.portal.navigation.api_service

At runtime when I execute the application I get the following exception:

java.lang.ClassCastException: class com.sapportals.portal.pcd.gl.PcdGlContext:com.sapportals.portal.prt.util.ApplicationClassLoader@44d2247a@com.sapportals.portal.prt.util.ApplicationClassLoader@44d2247a(D:\usr\sap\TT1\JC01\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.portal.pcd.glservice\private\lib\com.sap.portal.pcd.glservice_core.jar;D:\usr\sap\TT1\JC01\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.portal.pcd.glservice\private\lib\concurrency.jar;D:\usr\sap\TT1\JC01\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.portal.pcd.glservice\private\lib\gl_core.jar;) incompatible with interface com.sap.portal.pcm.admin.IAdminBase:com.sap.engine.core.service630.container.ComponentClassLoader@52fe21c2@library:tc~epbc~pcm~adminapi~java

This occurs at line 12 in the code above.

Any help would be highly appreciated.

Melwyn
