In the web application, logged in users are saved to the session via session.setAttribute("loggedIn");.
I take in various user data into a servlet, validate and then perform a HTTP PUT request and then reset the person object by overwriting the session attribute, "loggedIn".
The issue I am having is that once the user edits their date of birth (dd-mm-yyyy input which is then converted into "dd-MMM-yyyy" for database input) after returning to their profile page, the date of birth field displays nothing.
However, if the user logsout (session.removeAttribute("loggedIn")) and then logs back in, the date displays appropriately. I have tried to auto logout and then login the user upon HTTP put, but it doesnt seem to work.
Thank you for any attempts at answering my question.
Date formatting code:
public String getDobAsFormatted(String input) throws ParseException
{
//take in yyyy-MM-dd'T'HH:mm:ss
SimpleDateFormat sdfDate = new SimpleDateFormat("dd-MM-yyyy");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date date = sdf.parse(input);
String formattedDate = sdfDate.format(date);
//output dd-mm-yyyy
return formattedDate;
}
public String getDobForDbInput(String input) throws ParseException
{
//take in dd-mm-yyyy
SimpleDateFormat sdfDate = new SimpleDateFormat("dd-MM-yyyy");
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");
Date date = sdfDate.parse(input);
String formattedDate = sdf.format(date);
//returns dd-mmm-yyyy
return formattedDate.toUpperCase();
}
