无法将类型为java.util.Date的4/23/12 12:00 AM转换为类java.sql.Date

Question

我正在将我的项目从WebSphere 7迁移到WebSphere 8,而我正在使用JSF 1.2.

我遇到了IBM JSF/html_extended标签以及标准转换器的问题,这些转换器主要是JSF 1.2核心组件.我也将我的Java EE版本从5更新到6(这可能不是原因).最后,还给出了一个组件树.

下面是我的堆栈跟踪:

重新声明背后的财产java.sql.*作为java.util.Date代替java.sql.Time.您根本不应该在模型中使用JDBC特定的数据类型.请注意,它java.sql.Date是子类java.sql.Time,因此在DAO中从数据库映射到模型时,根本不需要转换它.
