} catch（ClassNotFoundException cE）{
System.out.println（Class Not Found Exception：+ cE.toString（））;

}
我知道提交的数据是实际上完全存储，但是我只是测试SQL的qorks和preparedStatement ...因此只存储部分提交的数据。
谢谢，
解决方案
尝试使用日期时间转换器。
< f：convertDateTime pattern =dd / MM / yyyy HH：mmtimeZone =GMT + 5/>
添加您自己的时区，这里是一个工作片段
< p：calendar id = endvalue =＃{message.endDate}mode =popuppattern =dd / MM / yyyy HH：mmsize =17>
< f：convertDateTime pattern =dd / MM / yyyy HH：mmtimeZone =GMT + 5/>
< / p：calendar>
I wrote a simple form and managed bean to store the data submitted to SQL server. downloaded sqljdbc and got it installed. The following occurs:
javax.servlet.ServletException: Cannot format given Object as a Date
unsure what is really happening...

I know the data submitted isn't actually being stored fully, but I am just testing if SQL qorks and preparedStatement...hence storing only part of the submitted data. Thanks,
解决方案
try using the date time converter.
<f:convertDateTime pattern="dd/MM/yyyy HH:mm" timeZone="GMT+5" />
add your own time zone ofcourse here is a working snippet
<p:calendar id="end" value="#{message.endDate}" mode="popup" pattern="dd/MM/yyyy HH:mm" size="17">
<f:convertDateTime pattern="dd/MM/yyyy HH:mm" timeZone="GMT+5" />
</p:calendar>
