Hi, this might help you out.
          

           if (!TeamPlatform.isStarted()) {
                     TeamPlatform.startup();
               }
           
            String rtcURL = "https:/****.com:9443/rm";
            String user = "**";
            String pass = "*";

            ITeamRepository repo = TeamPlatform.getTeamRepositoryService().getTeamRepository(rtcURL);

            IProgressMonitor MONITOR = new NullProgressMonitor();

            repo.registerLoginHandler(new LoginHandler(user, pass));

            repo.login(MONITOR);
            
            IProcessItemService service = (IProcessItemService) repo.getClientLibrary(IProcessItemService.class);
          
            IProcessDefinition[] definitions = null;

            IProcessDefinition processDefinition = service.findProcessDefinition(processId,
                    IProcessItemService.ALL_PROPERTIES, MONITOR);

            IArtifactTypeManager artifactTypeManager;

            if (processDefinition == null) {
                // Create the definition if it does not exist.
                definitions = service.deployPredefinedProcessDefinitions(new String[] { processId }, MONITOR);
             
                if (definitions.length != 0) {
                    processDefinition = definitions[0];
                } else {
                    throw new TeamRepositoryException("Process template " + processId + " does not exist.");
                }
            }

            if (processDefinition == null) {
                throw new TeamRepositoryException("Could not find Predefined Process " + processId);
            }

            // ---- creation of project area code

            IProjectArea project = service.createProjectArea();

            project.setName(name);
            project.setProcessDefinition(processDefinition);
            project.getDescription().setSummary("Test Process Summary");

            // Save project area that uses the provided process

            service.save(project, MONITOR);

            service.initialize(project, MONITOR);
