How to create project area programmatically using java API?

    public String createProject(String name, String processId) throws TeamRepositoryException{
        String msg = "Created project " + name + " with process id Name " + processId;            

        IProcessItemService service = (IProcessItemService)repo.getClientLibrary(IProcessItemService.class);
        IProcessDefinition definition = service.findProcessDefinition(processId,IProcessItemService.ALL_PROPERTIES, MONITOR);
        
        if (definition == null) {
            throw new TeamRepositoryException("Could not find Predefined Process " + processId);            
        }
        IProjectArea project = service.createProjectArea();
        project.setName(name);
        project.setProcessDefinition(definition);        
        service.save(project, MONITOR);

        // Set project access
        setVisibility(name,false,false,true);

        service.initialize(project, MONITOR);

        return msg;
    }
