How to retrieve TIMESTAMP value from MySQL database

Question

I have this in my MODEL:

public Timestamp getDateadded() {
    return dateadded;
}

/**
 * @param dateadded the dateadded to set
 */
public void setDateadded(Timestamp dateadded) {
    this.dateadded = dateadded;
}

Which is used by my Data Access Object to get and set the time from the database:

while(rs.next())
         {
             comment = new Comment();
             comment.setDetails(rs.getString("details"));
             comment.setDateadded(rs.getTimestamp("dateadded"));
             comment.setUrgency(rs.getInt("urgency"));
             commentList.add(comment);
         }

After getting the values, the values are set to an arrayList which is forwarded to a page and output using JSTL.

However, I CANNOT figure out why it does not show ANY result.

DEBUGGING TRIED: I printed a non-null arrayList and got something like this [Models.Project@17735867] and when I print the value of COMMENT (the one that has error) the output of the print is just []

So that means there is an error in the arrayList.

Would any of you know what's wrong with my code?

将调试放在ResultSet ，确保其具有数据或在while循环代码中进入吗？
