RTC 5.0.2 Failed to start a participant "CRJAZ6011E"

there is no workitem common service.
there IS a workitem common class

it is not referenced in my plugin.xml

            if (auditable instanceof IWorkItem) {

                IAuditableCommon auditableCommon= saveParameter.getSaveOperationParameter().getAuditableCommon();
                IWorkItemCommon workItemCommon= auditableCommon.getPeer(IWorkItemCommon.class);

Please check the prerequisites in the plugin.xml (see https://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/ image at the end of the post) and check the services you instantiate.

Just to be up front my understanding of the plugin process is at a basic level. Also note I am fairly new to the Java language.   I successfully went through the RTC Extension Workshop 5.x.  I have been able to debug my participant using the Jetty Server process that was shown in the workshop.

 

What I am trying to do with my participant is when a user presses the Save button, I would like to get the data from targeted fields (both custom and built-in) on the workitem so I can update an external program with the data.  After searching this forum I realized there are many ways to accomplish this.  I found a piece of code on the fourm (see link above) authored by Hakki Bozkurt  that was marked as an accepted answer and appeared to fit what I was trying to do.

 

After adding the <RequiredService interface="com.ibm.team.workitem.service.IWorkItemCommon"/>  to the plugin.xml on my participant. And running the participant I receive the error you see in my initial post. I noticed after that in Hakki had set the service to be optional.  I changed my plugin.xml to reflect that.

 

When I reran the participant fired and stopped on the breakpoint I set, but when I stepped passed the line “IWorkItemCommon workItemService= (IWorkItemCommon) getService(IWorkItemCommon.class);” I received the exception:

 

The service 'ca.navcan.jazz.updatenesamr.participant.UpdateNesaMR@7e617e61' failed to find the required service 'interface com.ibm.team.workitem.common.IWorkItemCommon'.  Check <prerequisites> in plugin.xml.

 

Hopefully this gives a better explanation of my issue.  I’m sure I am missing something simple in my code, or there may be a more efficient way to accomplish the same thing. I’ve pasted the section of the code below.  Any help would be greatly appreciated.  Thanks

My code:

 

                        Object data = operation.getOperationData();

                        ISaveParameter saveParameter = null;

 

                        if (data instanceof ISaveParameter) {

                                    saveParameter = (ISaveParameter) data;

                                    IAuditable newState = saveParameter.getNewState();

                                    IAuditable oldState = saveParameter.getOldState();

                                    if (newState instanceof IAuditable) {

                                                IWorkItemCommon workItemService = (IWorkItemCommon) getService(IWorkItemCommon.class);// You to add this class in plugin.xml

 

                                                // loop through and get the field data we need

                                                while (i <= 17) {

                                                            IAttribute attribute = workItemService.findAttribute(

                                                                                    operation.getProcessArea().getProjectArea(),

                                                                                    jazzFieldId[i], monitor);

                                                            if (attribute instanceof IWorkItem){

                                                                        IWorkItem sourceWorkItem = (IWorkItem) attribute;

                                                                        workItemFields[i] = sourceWorkItem.getValue(attribute).toString(); // return object type data maybe you want to convert      

                                                            }

                                                }

                                                // see if this a new workitem

                                                if (oldState == null) { // its a new workitem

                                                            action = 0;

                                                } else {

                                                            action = 1;

                                                }

                                    }

                        }
