 You first need to get a reference to the work item being saved as part of the operation: 
Object data = operation.getOperationData();
if(data instanceof ISaveParameter) {
	ISaveParameter saveParameter = (ISaveParameter) data;
	IAuditable newState = saveParameter.getNewState();
	if(newState instanceof IAuditable) {
		IWorkItem workItemNewState = (IWorkItem) newState;
You then need to get a reference to the attribute(s) you want to update: 
IWorkItemServer workItemServer = getService(IWorkItemServer.class);
IAttribute customAttribute = 
		workItemServer.findAttribute(workItemNewState.getProjectArea(), "customAttributeId", null);
You then need to get a working copy of the work item you want to update: 
IWorkItem workingCopy = (IWorkItem) workItemNewState.getWorkingCopy();
Lastly you need to update the value of the attribute and save the working copy: 
workingCopy.setValue(customAttribute, "my new value");
workItemServer.saveWorkItem2(workingCopy, null, null);

Full code looks like this: 
public void run(AdvisableOperation operation, IProcessConfigurationElement participantConfig,
		IParticipantInfoCollector collector, IProgressMonitor monitor) throws TeamRepositoryException {
	Object data = operation.getOperationData();
	if(data instanceof ISaveParameter) {
		ISaveParameter saveParameter = (ISaveParameter) data;
		IAuditable newState = saveParameter.getNewState();
		if(newState instanceof IAuditable) {
			IWorkItem workItemNewState = (IWorkItem) newState;
			
			IWorkItem workingCopy = (IWorkItem) workItemNewState.getWorkingCopy();
			IWorkItemServer workItemServer = getService(IWorkItemServer.class);
			IAttribute customAttribute = 
					workItemServer.findAttribute(workItemNewState.getProjectArea(), "customAttribute", null);
			workingCopy.setValue(customAttribute, "my new value");
			workItemServer.saveWorkItem2(workingCopy, null, null);

		}
	}
}

Thanks for reply Jared,

I tried your code but I was getting the following exception:

Exception running followup action.

An unhandled exception occurred during "testing participant".

Stale Data.

any help???

Remove the workItemServer.saveWorkItem2(workingCopy, null, null); line from the code. As the operation advisor is running in the current context so this method will be called automatically. Saving work item twice is causing error.

If I am not wrong this code you are running inside the server then I thin working copy is also not needed.

First remove the line above if not working then do something like this

IWorkItem workItemNewState = (IWorkItem) newState;

        IWorkItemServer workItemServer = getService(IWorkItemServer.class);
        IAttribute customAttribute = 
                workItemServer.findAttribute(workItemNewState.getProjectArea(), "customAttribute", null);
        workItemNewState.setValue(customAttribute, "my new value");
