Problem
The service 'helloworldadvisor.WorkItemSave@332a332a' failed to find the required service 'interface com.ibm.team.workitem.common.IAuditableCommon'. Check <prerequisites> in plugin.xml.

plugin.xml

	<?xml version="1.0" encoding="UTF-8"?>
	<?eclipse version="3.4"?>
	<plugin>
	   <extension
	         point="com.ibm.team.process.service.operationAdvisors">
	      <operationAdvisor
	            class="helloworldadvisor.WorkItemSave"
	            id="HelloWorldAdvisor.prohibitSave"
	            name="Prohibit Save (Hello World Advisor)"
	            operationId="com.ibm.team.workitem.operation.workItemSave">
	      </operationAdvisor>
	   </extension>
	
	</plugin>

			System.out.println("--->return");
			return;
		}
		
		System.out.println("--->next step001");
	    Identifier newStateId = newState.getState2();
	    String state = newStateId.getStringIdentifier(); 
		if (null != state) {
			System.out.println("uuidStateId--->" + state);
		}
		
		System.out.println("--->next step002");
		//set currentUser to owner
		newState.setOwner(auditableCommon.getUser());
		
		IWorkItemCommon workItemCommon= this.getService(IWorkItemCommon.class);
		//set currentUser to approveaaa
		IAttribute target= workItemCommon.findAttribute(newState.getProjectArea(), "approveaaa", monitor);

		System.out.println("--->next step004");
		IAuditable auditable = saveParameter.getNewState();

Carefully read https://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/
You also might want to search this forum. I am pretty sure the question has been asked and answered before.

I think I also sent you a bunch of copies of my blog posts and they also have links to download the code, so you can check e.g. the differences in the plugin XML.

The prerequisites are set this way:

A better way to say this

YOU must explicitly define all the dependent services you wish to use in the plugin.xml of your plugin. RTC does not support open binding.
