getService(Class) throws java.lang.IllegalArgumentException:

Hi

I am trying to modify the properties of another workitem when save is invoked by code looks like this

import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.core.runtime.IStatus;
import com.ibm.team.process.common.IProcessConfigurationElement;
import com.ibm.team.process.common.advice.AdvisableOperation;
import com.ibm.team.process.common.advice.IAdvisorInfoCollector;
import com.ibm.team.process.common.advice.runtime.IOperationAdvisor;
import com.ibm.team.repository.common.IAuditable;
import com.ibm.team.repository.common.TeamRepositoryException;
import com.ibm.team.repository.service.AbstractService;
import com.ibm.team.workitem.common.ISaveParameter;
import com.ibm.team.workitem.common.model.IComment;
import com.ibm.team.workitem.common.model.IWorkItem;
import com.ibm.team.workitem.service.IWorkItemServer;

public class WorkItemSyncServer extends AbstractService implements IOperationAdvisor {

public boolean isCopiedWorkItem=false;
public String sWID="";
public int sourceWorkItemID=-1;

@SuppressWarnings("deprecation")
public void run(AdvisableOperation operation,
IProcessConfigurationElement advisorConfiguration,
IAdvisorInfoCollector collector, IProgressMonitor monitor)
throws TeamRepositoryException {
// TODO Auto-generated method stub
Object data= operation.getOperationData();
if (data instanceof ISaveParameter)
{
IAuditable auditable= ((ISaveParameter)data).getNewState();
if (auditable instanceof IWorkItem) {
IWorkItem sourceworkItem=(IWorkItem) auditable;
try{
IComment sourceComments[]=sourceworkItem.getComments().getContents();
if (sourceComments.length>0)
isCopiedWorkItem=searchForWorkItemID(sourceComments);
}
catch (Exception e){
isCopiedWorkItem=false;
e.printStackTrace();
}
if (isCopiedWorkItem){
// Search the source work Item and Modify the contents
IWorkItemServer itemServer=getService(com.ibm.team.workitem.service.IWorkItemServer.class);
IWorkItem itemCopy=(IWorkItem)itemServer.findWorkItemById(sourceWorkItemID, IWorkItem.FULL_PROFILE, null).getWorkingCopy();
//modify attributes
itemCopy.setState2(sourceworkItem.getState2());
IStatus result= itemServer.saveWorkItem2(itemCopy, null, null);
if (!result.isOK()) {
// deal with errors
System.out.println("Save Work Item 2 failed ....");
}
}
}
}
}
}

When I try to save a work item after getting the ID it throws :
java.lang.IllegalArgumentException: The service 'com.ibm.team.workitem.save.WorkItemSyncServer@38803880' failed to find the required service 'interface com.ibm.team.workitem.service.IWorkItemServer'. Check <prerequisites> in plugin.xml.

Any help would be great ...

I forgot to add the plugin.xml looks as follows

plugin
extension
operationAdvisor
description
This is used for synchronizing two work items for its
state and comments within the same server repository
/description
/operationAdvisor
/extension
prerequisites
<requiredService
</prerequisites
/plugin

not sure if the prerequsites tag is correctly mentioned
