How query workItem by some attributes in java code?

Hello,every one ,I have a question that is

How query workItem by some attributes in java code?

for example : I want to find out the workItem's count by owner="Jurry" and
workitemtype="requeriment" and severity="high" ??
can some one tell me some solutionin java code??


in additional
there I found some code

IAttribute attribute_001 = workItemClient.findAttribute(projectArea, "com.ibm.team.workitem.attribute.severity", null);

			IQueryableAttribute attribute_002= findAttribute(projectArea, auditableClient, "com.ibm.team.workitem.attribute.owner", null);

			if(null!=attribute_001)

			{

				logger.info("----"+attribute_001+"----");

			}

			AttributeExpression attrExpression_001= new AttributeExpression(attribute_002, AttributeOperation.EQUALS, password);

			AttributeExpression attrExpression_002= new AttributeExpression(attribute_002, AttributeOperation.EQUALS, password);

			

			//SimilarityExpression similarityExpression= new SimilarityExpression(workItemType,null);

			Term term= new Term(Operator.AND);

			term.add(attrExpression_001);

			term.add(attrExpression_002);



			IQueryResult ddd = queryClient.getResolvedExpressionResults(projectArea, term, IWorkItem.SMALL_PROFILE);

			ResultSize ffff  = ddd.getResultSize(null);

			logger.info(ffff.getTotal());

Thank you very much!!!

You can use the RQM REST API (http://jazz.net/wiki/bin/view/Main/RqmApi) to GET work items. However, the API does not provide query support so you will have filter the results based on your predicate(s). The fields parameter (https://jazz.net/wiki/bin/view/Main/RqmApi#fields) is intended for filtering results but does not support work items (https://jazz.net/wiki/bin/view/Main/RqmApi#SupportedFieldsResources). You may open an enhancement for adding this support.

In addition, you may use the RTC API (https://jazz.net/wiki/bin/view/Main/ResourceOrientedWorkItemAPIv2) to get, create, modify, and query work items.
