＆＃13; 我把所有的罐子放进了程序。添加我的sql连接器

Answer 1

我发现错误是reg.cfg.xml文件现在工作正常。但是在数据库中存储数据时显示名字和姓氏为null并在下面添加电话和密码的问题更多

＆＃13;

mysql> select *from registrar_webapp;
+----+-----------+----------+----------+------------+
| ID | FIRSTNAME | LASTNAME | PASSWORD | PHONE      |
+----+-----------+----------+----------+------------+
|  1 | NULL      | NULL     | 123456   | 9741178304 |
+----+-----------+----------+----------+------------+
1 row in set (0.00 sec)

＆＃13;

Answer 2

你提到过form action =＆＃34; register.jsp＆＃34;，你发布了register.jsp页吗？

建议：尝试将Servlet用于控制器而不是使用Scriplets ..

如果需要，请使用JSP和Hibernate交叉检查here以获取CRUD流程。
