can someone help to convert this query to Hql

select involog.id,exelog.id,exelog..state from org.jbpm.model.log.impl.InvocationLogImpl involog, org.jbpm.model.log.impl.ExecutionLogImpl exelog where exelog.invocationLog=involog.id and involog.serviceMethod='endOfState' and involog.actorId="testuser"

mappings are as below :
these files are from jbpm :
