			Class entityClass) {
		Object entity;
		try {
			entity = entityClass.newInstance();
			Map params = request.getParameterMap();
			Set entrySet = params.entrySet();
			Iterator iter = entrySet.iterator();
			while (iter.hasNext()) {
				Map.Entry entry = (Map.Entry) iter.next();
				String name = (String) entry.getKey();
				String[] values = (String[]) entry.getValue();
				setProperty(name, values, entity);
			}
		} catch (Exception e) {
			e.printStackTrace();
			throw new RuntimeException(e);
