JSF :: Primefaces Calendar Component Passing Incorrect Date Format
Jan 27, 2015
I am using the calendar component of the primefaces and I am using the attribute pattern="MM/dd/yyyy.But when I print the values in my MBean along with the selected date event the timeZone (i think) is printed as Sun Mar 29 00:00:00 IST 2015 I do not understand why its printed even though I have set the pattern.Part of my code :
I have a problem to display a popup with the information of the registered event. I would like the user to hover over a particular event exhibited only the description of the event without having to click on the event to view information. I would like to make an ajax request to that was displayed a popup.
But do not know how to implement jquery and javascript. Well, I am new to programming. My code that generates the schedule is as follows:
In my Bean have methods that make the selection of date and event. Have I configured the option of setEditable to true. Ajax function, jquery or javascript to show the popup containing only observation and event date. And looked at the documentation of primefaces and not found any implementation to solve my problem.
Given a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?
Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...
I have a PrimeFaces page with a calendar component on it. Radio buttons on that page work fine and call the setter method on the back end. The Calendar however doesn't call the setter. The getter method is called on page display.I'm using the PrimeFaces v 5.0 jar file.
I am working on an application using JSP and SERVLET.
Somewhere I need to show the reminders on a particular date on calendar (Jsp page). I have used javascript for calendar and entering reminder from another UI. So I need to display an image on the calendar date which is matching with reminder date. The problem is how can I display the image on that date which is on calendar.
I need to add a few days to make an end date (for instance the start date is the first date selected, and then the end date is x amount of days after that... I think I should be using the add() method but I am not quite sure of where or how to do so)...
Java Code:
//Get an instance of Calendar and DateFormat class, and get current date from the system using OnClick method Calendar startVacation = Calendar.getInstance(); DateFormat fmtDate = DateFormat.getDateInstance(); DatePickerDialog.OnDateSetListener startVaca = new DatePickerDialog.OnDateSetListener() {
I'm a Java beginner and I'm having issues implementing Java's GregorianCalendar into my project. I'm writing to specific test code that passes arguments into an instantiated GregCal class. My problem is that I'm not sure how to pass the arguments through to my constructors and methods, or if I'm even supposed to do that at all. Date formatting is another issue, but I'll be glad If I can just get the dates in and back out. Here is some of the code:
Test code: // Create a Student using the default constructor Student newStudent = new Student(); GregorianCalendar dateOfBirth = new GregorianCalendar(75,7, 3); newStudent.setDateOfBirth(dateOfBirth); GregorianCalendar dateOfGraduation = new GregorianCalendar(90, 6, 10); newStudent.setDateOfGraduation(dateOfGraduation);
Setter: public void setDateOfBirth (GregorianCalendar dateOfBirth){ this.dateOfBirth = dateOfBirth; }
I know that's not much to work with, but that's exactly my issue. I can't seem to find a reliable and UNDERSTANDABLE tutorial for java.util.GregorianCalendar anywhere. All of the existing documentation is beyond my grasp at this point. I'm assuming I need to declare and initialize MONTH, DAY, YEAR variables somewhere in order for the arguments to be passed through correctly. I'm just not sure where or how.
<script type="text/javascript"> function CompareDates(id) { var monName = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec"); var d = new Date(id); var curr_date = d.getDate();
[code]....
why the default date format that the textbox accepts is in 'mm/dd/yyyy'.For example if i entered "13-05-2014" then it would return an error stating date is invalid.If i entered "12-05-2014" then it would return "5 Dec, 2014".I did not declare any dateformat anywhere except for the datepickers which as shown above, is 'd MMM, yyyy'.Before this happened i trialed and error many different kind of codes to try to validate the date however it all didnt work and so i reverted it all back to the original codes.Last time the dateformat that the textbox accepted was 'dd/mm/yyyy' and it worked fine with my javascript function except the validation part.
Now it still works except that the dateformat changed to 'mm/dd/yyyy'.I did try to use console.log to find out what's wrong but there were no error messages.Why has the dateformat changed by itself?
When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:
1. First I will get the date from the email header by the following code.
I've created a method named parseStringToDate this method takes a string parameter and parse it to the date: here is my code:
public Date parseStringToDate(String date) throws ParseException{ DateFormat formatter = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.SHORT, Locale.getDefault()); return formatter.parse(date); }
i'm trying to parse a String to date then:
public static void main(String args[]) { MyDate a = new MyDate(); try { Date d = a.parseStringToDate("Wednesday, August 13, 2014 3:33 PM"); System.out.println(d); } catch (ParseException e) { e.printStackTrace(); } }
As i've defined DateFormat in the method, now i'm passing it a date accordingly: "Wednesday, August 13, 2014 3:33 PM" And the output is: Wed Aug 13 15:33:00 PKT 2014
Which is not equal to the format i gave it.. how can i change its format to same as i've given input. InShort i want to parse a string to date and it should convert that String to date with exactly the same format.
I have a piece of code as below for date format conversion.
DateFormat formatter1 ; DateFormat formatter2 ; Date date = new Date();
formatter1 = new SimpleDateFormat("yyyy-mm-dd"); date = formatter1.parse("1952-12-10"); System.out.println("before format, date is " + date);
formatter2 = new SimpleDateFormat("dd-MMM-yy"); formatter2.format(date); System.out.println("after format, date is " +formatter2.format(date));I would like to change 1952-12-10 become 10-DEC-52, h
However, I am getting below output:
before format, date is Thu Jan 10 00:12:00 MYT 1952 after format, date is 10-Jan-52
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000" at java.text.DateFormat.parse(DateFormat.java:357)
In my project i am facing an problem, The My SQL Data base will accept the date format of yyyy/mm/dd only as "Date" data type but in my program i wants to use dd/mm/yyyy format. (i have this same format now) that's why I am unable to insert / retrieve it..
The intent of the code is to read date from a file, does calculation and then displays that data in a table format on the screen. Then creates another file with those values:
Reads file: Beginningbalance.txt Displays Data with calculation Creates a file called "Newbalance.txt" with the following values:
111 251.41 222 402.00
With the way the code is written I can get it to create the file but it only displays one of the customers (111). I know that I need to create a loop but I am not sure how to build that. I tried creating another while loop and changing it to outFile but that was without success.
import java.io.*; import java.util.Scanner; import java.text.DecimalFormat; public class Output { public static void main(String[]args) throws IOException {
I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel(); GridBagLayout qPanelLayout = new GridBagLayout(); qPanelLayout.columnWidths = new int[] { 0 }; qPanelLayout.rowHeights = new int[] { 0 }; qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE }; qPanelLayout.rowWeights = new double[] { 0.0 }; panel.setLayout(qPanelLayout); componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) { GridBagConstraints gbc = new GridBagConstraints(); gbc.fill = GridBagConstraints.HORIZONTAL; gbc.insets = new Insets(2,2,2,2); gbc.gridx = 0; gbc.gridy = componentCount++; panel.add(comp, gbc_questionPane1); }
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?
I'm making a program to demonstrate Exception Handling. (Note: the code was written inside towards out). The user is prompted to input two values (integers) and then the program will divide those values and output the result.
I then added the "try" and "catch keywords for exception handling-instead of the program shutting down if an error occurs, the words "you cant do that" will appear
I then added a while loop to allow the user another chance to input usable values. Of course, I made sure to make a termination to the loop as well.
Everything works as expected if the user inputs e.g 8 divided by 0. in that case exception occurse, the user is told "you cant do that", is then prompted to start over and so forth until he gives usable integers. then the program continues to the termination. However, if the user inputs a String , e.g 9 divided by xyz, then the program goes into an endless loop
My question is:
1) why does a String cause an endless loop ( I have a theory)
2)why does the loop occur as soon as I put in an incorrect value- is the while loop somehow in extant? somehow always waiting? (hard to picture it)
3) lastly, what would be the correct code to handle and exception caused by a String (as opposed to being caused by impossible to execute math)
Here is the program
package inschool; /* *GOAL: to allow for an exception to occur without causing the entire program to stop. *NOTE: the coding was written from the center outwards (e.g first "System.out.println", then "try", then "do") */ import java.util.*; public class L82_ExceptionHandling { public static void main(String[] args) { Scanner input = new Scanner(System.in);
I have an requirement of splitting a Date-Time String i.e. 2013/07/26 07:05:36 As you observe the above string has Date and Time with space in between them.
Now I want just want split the string not by delimiter but by length i.e. after 10th place and then assign it to 2 variable i.e. Date <----2013/07/26 and Time <---07:05:36 separately.
1. Write an algorithm that asks the user for your birth date and the current date and displays how many days has passed since then (remember that April, June, September and November has 30 days, February has 29 on leap years, and the rest 31)
2. Write an algorithm that asks the user a number (save it as N) and displays the N term of the Fibonnacci series (take it as 1, 1, 2, 3, 5 ...)
I've been stuck on this one for a while. If you scroll down to the while loop there is some code that calculates the angle of a triangle created by two circles colliding. The problem is, The angle between the hypotenuse / x axis, and the angel between the hypotenuse / y axis never go above 65 degrees and i have no clue why?
