Converet from java.sql.Timestamp to java.util.Date

[Hussein Baghdadi]

Hi.
In our database table, we have a timestamp column.
At runtime, Hibernate cast it to java.sql.Timestamp class which it is not included in GWT JRE emulation library.
I tried this:
java.util.Date d = new java.util.Date(fetchedObject.getCreationTimestamp().getTime());
But I lost the time information.
Any walk around you aware of?
Thanks.

Are you sure that the time went into the column to begin with?
Or better yet that it's in your timestamp object after selecting it?
Because getTime in Timestamp should get your the long you're looking for when constructing your Date.

Note that class java.sql.Timestamp is a subclass of java.util.Date. So the Timestamp object that you have is already a java.util.Date object.

Yes but Timestamp class contains the nano second part which java.util.Date doesn't handle it.
When I'm trying to display the converted Date object (according to my previous posted code), I got:
date info .. 00:00:00 ...
Obviously, I lost the time.

When you convert from timestamp to date, time will not be lost. the problem might be when you get date from database it might truncate time.

see the below eg:

the long value of timestamp, util.date, sql.date will be same. only when it is printed it will be printed in different way. but you are converting into util.date so will not loose time only nano sec. will not come

Timestamp st = new Timestamp(System.currentTimeMillis());
java.util.Date date1 = new java.util.Date(st.getTime());
java.sql.Date date2 = new java.sql.Date(st.getTime());

System.out.println(st); print date,Time, nano sec
System.out.println(date1); print date, time
System.out.println(date2); print date
