how to Update project area with process template content through RTC API

		Map pd = projectArea.getProcessData();

		IContent content = (IContent) pd
				.get(ProcessContentKeys.PROCESS_SPECIFICATION_KEY);
		if (content != null) {
			String processConfig = createStringFromContent(teamRepository,
					content, monitor);
			String newProcessConfig = processConfig.replace(
					"this-is-a-fake-url", "http://localhost/index.html");
			IContent newContent = createContentFromString(teamRepository,
					newProcessConfig, monitor);
			pd.put(ProcessContentKeys.PROCESS_SPECIFICATION_KEY, newContent);
			IProcessItemService processItemService = (IProcessItemService) teamRepository
					.getClientLibrary(IProcessItemService.class);
			processItemService.save(projectArea, monitor);
		}
