Formatting a date as a string, from bean to javascript - java

In my bean, I'm formatting a date as a string:
public void setStrDate(Date dte) {
DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
this.strDate = df.format(dte);
}
In my js file, I'm grabbing the data:
$('#content').data("myDate", <c:out value="${myBean.strDate}"/>);
And in my js, displaying the data:
$('#sideBar').find("p[class=stat]").append($('#content').data("myDate"));
The date comes over as 10/10/2014. I even see it in the developer tools this way:
$('#content').data("myDate", 10/10/2014);
But on the webpage, it shows up as 0.0004965243296921549
How can I format this?

You need to put quotes around your date when you output it. Make it read:
$('#content').data("myDate", "<c:out value="${myBean.strDate}"/>");
Why is it resulting in 0.0004965243296921549
10/10/2014 is actually being evaluated as math, 10/10 = 1 -> 1/2014=0.0004965243296921549
*if this code "<c:out value="${myBean.strDate}"/>" is making your editor flip out about the quotes then you can use single quotes as well '<c:out value="${myBean.strDate}"/>'

Java: Formatting a Date inside of a string

I know I'm probably doing something wrong, but I am trying to format a Date that is currently stored inside of a string but it won't let me parse it to a String because it doesn't recognize it as a Date (because it's in a String variable) and won't let me format it because it cannot format it in its current state. For reference, I am making a time clock application.
I apologize if I'm doing something stupid but I am fairly new to this and have never used SimpleDateFormat before. I put some snippets of code below:
ArrayList<String> punchHistoryTimes = new ArrayList<String>();
SimpleDateFormat sdf =new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
public void updatePunchHistory(Sheet sheet){
for(int rowNum:rowNumbers){
punchHistoryTimes.add(sheet.getRow(rowNum).getCell(1).getStringCellValue());
punchHistory.add(new JLabel(sheet.getRow(rowNum).getCell(0).getRichStringCellValue().getString()+ " " + sheet.getRow(rowNum).getCell(1).getRichStringCellValue().getString()+ " " + sheet.getRow(rowNum).getCell(2).getRichStringCellValue().getString()));
}
}
//other code is above this but not relevant to the issue
currentEmployee.setEndTime(sdf.format(currentDate));
if(punchHistory.get(punchHistory.size()-1).getText().contains("Clocked In")){
calcTimeWorked(punchHistory.get(punchHistoryTimes.size()-1).getText(),currentEmployee.getEndTime());
}else{
//This line below is where the error is happening
//value of currentEmployee.getStartTime() at error: 1654653731536
//value of currentEmployee.getEndTime() at error: 07-06-2022 21:02:12
//Both currentEmployee.getStartTime() and currentEmployee.getEndTime() are stored as Strings
calcTimeWorked(currentEmployee.getStartTime(),currentEmployee.getEndTime());
}
currentEmployee.setHoursWorked(differenceInTime);
I tried using the debugger and it shows the error is that it cannot parse 1654653731536. I understand the issue but cannot get a solution. I believe the issue is because when it stores the value in the excel file it is storing the date as a string but then when it pulls the date back out of the excel later (the application would have been closed between these events) it views it as a string and does not recognize that there is a Date inside of the String. Is there any way to cast the String 1654653731536 to a Date?

I am not able to write the xpath for dynamic element

I am facing a problem in the following scenario. Please help me guys.
Scenario-
open URL- https://member.bseindia.com/
Click on <MF> folder.
Click on <COMMON>.
Click on <DEC-2017> folder.
Click on <Current date> folder
<Current date> folder is generating dynamically everyday.
I have written the code but not able to write the xpath for dynamic folder. ex-11-12-2017
public class bseIndia
{
String driverPath = "C:\\Users\\Public\\Public Desktop";
public WebDriver driver;
#BeforeClass
public void setUp()
{
System.setProperty("webdriver.chrome.driver","F:\\Abhishek\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
}
#Test
public void nav() throws InterruptedException
{
System.setProperty("webdriver.gecko.driver", "F:\\Abhishek\\Document\\geckodriver.exe");
System.setProperty("webdriver.chrome.driver", driverPath+"chromedriver.exe");
driver.navigate().to("https://member.bseindia.com");
driver.findElement(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl06_lbFolderItem']")).click();
driver.findElement(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl02_lbFolderItem']")).click();
driver.findElement(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl02_lbFolderItem']")).click();
//driver.findElement(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl06_lbFolderItem']")).click();
Date date=new Date();
SimpleDateFormat sm = new SimpleDateFormat("dd-mm-yyyy");
driver.findElements(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl02_lbFolderItem']"));
boolean b= driver.findElements(By.xpath("//a[#id='FileGridVB1_gvFiles_ctl02_lbFolderItem']")).contains(sm.format(date));
if(b==true)
{
here I have write the xpath for dynamic folder.
}
}
}
I would do things a bit differently. I generally try to look at things like this where I'm repeating actions and try to come up with a general function that will take care of it. In this case, you are clicking a folder given a particular expected name. I would then write a function clickOnFolder(String folderName) so that I can handle that case. Then you would just call that function each time you needed to click a folder. The code is below
public static void clickOnFolder(String folderName)
{
driver.findElement(By.xpath("//a[contains(., '" + folderName + "')]")).click();
}
Using XPath, we are finding an A tag that contains the text of the folder name whether it be "MF" or "COMMON" or today's date. This general function can be used to click any folder.
In your question, one of your issues is that you need to find the folder by today's date. You've asked for the final folder name that contains the day/month/year but you really need it for the containing folder also to do it properly (DEC-2017).
To handle these dates, you just need to get today's date in the desired format and find the A tag that represents the folder using XPath. The code to get today's date into the proper format is below.
I've tested the code below and it works.
String url = "https://member.bseindia.com/";
driver.navigate().to(url);
// get date formats for folder names
LocalDateTime currentTime = LocalDateTime.now();
String todaysDate = currentTime.format(DateTimeFormatter.ofPattern("dd-MM-yyyy"));
String monthYear = currentTime.format(DateTimeFormatter.ofPattern("MMM-yyyy")).toUpperCase();
clickOnFolder("MF");
clickOnFolder("COMMON");
clickOnFolder(monthYear);
clickOnFolder(todaysDate);
Your code line that starts with boolean b will not work for several reasons.
You are using .findElements() (plural) which returns a collection so you would need to look at an individual element, e.g. .get(0), to do a comparison.
You are comparing a String to a WebElement which will always fail. What you want is something like driver.findElement(locator).getText().contains("some string");.
Your date format is using mm which in datetime formats means minutes, not months. You want MM.

Formatting UTC date-time's partial seconds

After parsing JSON UTC date-time data from a server, I was presented with
2017-03-27 16:27:45.567
... is there any way to format this without using tedious amount of String manipulation so that the seconds part is rounded up to 46 prior to passing it in as a DateTimeFormat pattern of say, "yyyy-MM-dd HH:mm:ss"?
You can round the second up like this:
DateTime dateTime = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss.SSS")
.withZoneUTC()
.parseDateTime("2017-03-27 16:27:45.567")
.secondOfMinute()
.roundCeilingCopy();
System.out.println(dateTime);
// 2017-03-27T16:27:46.000Z
Have you looked at (and could you use) the MomentJS library? I had issues with reading various date formats from the server and making sense of them in JavaScript code (which led me here). Since then, I've used MomentJS and working with dates/times in JavaScript has been much easier.
Here is an example:
<script>
try
{
var myDateString = "2017-03-27 16:27:45.567";
var d = moment(myDateString);
var result = d.format('YYYY/MM/DD HH:mm:ss');
alert("Simple Format: " + result);
// If we have millliseconds, increment to the next second so that
// we can then get its 'floor' by using the startOf() function.
if(d.millisecond() > 0)
d = d.add(1, 'second');
result = d.startOf('second').format('YYYY/MM/DD HH:mm:ss');
alert("Rounded Format: " + result);
}
catch(er)
{
console.log(er);
}
</script>
But of course, you'll probably want to wrap this logic into a function.

DBunit - Unable to typecast <1997/02/14> to TimeStamp

I'm doing an integration testing with DBUnit (2.49) + Hibernate (4.1.3) following this tutorial.
Production database : Oracle 10
Test database : Hsqldb 2.3.3
Context
My data contains the current format of date : yyyy/MM/dd. However,according to DBUnit faq, DBUnit only supports this format yyyy-mm-dd hh:mm:ss.fffffffff, so I had to create a new format for TimeStamp.
How I tried to fix it
I created a CustomTimeStampDataType based on this tutorial. I changed this part:
String formats[] = {"yyyy-MM-dd HH:mm", "yyyy-MM-dd HH:mm a", "yyyy-MM-dd HH:mm:ss.fffffffff"};
into this one:
String formats[] = {"yyyy/MM/dd"};
I created a CustomeDataTypeFactory following the same tutorial. I only make it extend Oracle10DataTypeFactory rather than DefaultDatatTypeFactory.
In HibernateDBUnitTestCase, I override setDatabaseConfig() with the following:
#Override
protected void setUpDatabaseConfig(DatabaseConfig config){
config.setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY, new CustomDataTypeFactory());
}
But I got new errors
I ran a unit test and got this error.
org.dbunit.dataset.datatype.TypeCastException: Unable to typecast value <1997/02/14> of type <java.lang.String> to TIMESTAMP

at java.sql.Timestamp.valueOf(Unknown Source)
at org.dbunit.dataset.datatype.TimestampDataType.typeCast(TimestampDataType.java:116)
... 20 more
That was weird, it seemed like my CustomTimeStamp was not called, so I changed the date in the dataset using the default format : 1997-02-14 00:00:00.0, and ran the unit test again. Then I got:
org.dbunit.dataset.datatype.TypeCastException: Unable to typecast value <1997-02-14 00:00:00.0> of type <java.lang.String> to TIMESTAMP

at test.HibernateDbUnitTestCase.setUp(HibernateDbUnitTestCase.java:85)
at test.PlayerTest.setUp(PlayerTest.java:117)
That means CustomTimeStamp was actually called. Seems like, the problem stemed from DatabaseTestCase.setUp which somehow called the wrong TimeStampDataType.
How could I fix this issue?
My first option was to replace every yyyy/MM/dd into yyyy-mm-dd in the dataset using regular expressions. This worked fine, until I had to test a method that selected a date based on a request (so the format is yyyy-mm-dd) and compared it to the current date. ( so the format is yyyy / mm / dd). Hsqldb can't compare two dates with different format.
My second option was to decompile dbunit.jar, rewrite TimeStampDataType based on the tutorial. I'm unfamiliar with bytecode writing so before entering uncharted waters, I wanted to know if you had another solution.
Thank you in advance
Fixed it!
So I ended up using my second option.
This is the detailed path for those who need it.
Download dbUnit.2.2.source.jar
Unzip the jar
Go to Eclipse, File > New > Java Project
Uncheck "Use default location"
In Location : specify the path to the new folder created from the jar
Click on Finish
Modify the TimestampDataType.java (if needed)
Instead of ts = java.sql.Timestamp.valueOf(stringValue); use the code below
String formats[] =
{"dd/MM/yyyy HH:mm:ss.SS"}; //and more depending on your need
Timestamp ts = null;
for (int i = 0; i < formats.length; i++)
{
SimpleDateFormat sdf = new SimpleDateFormat(formats[i]);
try {
java.util.Date date = sdf.parse(stringValue);
ts = new Timestamp(date.getTime());
return ts;
}
catch( ParseException e) {
}
Modify the DateDataType.java (if needed)
Instead of return java.sql.Date.valueOf(stringValue); , use the code below
String formats[] =
{"dd/MM/yyyy"}; //and more depending on your need
for (int i = 0; i < formats.length; i++)
{
SimpleDateFormat sdf = new SimpleDateFormat(formats[i]);
try {
java.util.Date date = sdf.parse(stringValue);
java.sql.Date datesql = new java.sql.Date(date.getTime());
return datesql;
}
catch( ParseException e) {
}
}
Right-click on your project, then Export
Select JAR file, then Next
Fill the export destination then Finish.
You just have to add this new jar to the library to make it work.

Java DynamicReports format dates regarding to locale

I'm using DynamicReports API for building reports.
I'm setting the Locale of the report and format the Date columns of the report, but the Dates are always formatted like 10/12/2009 10:54:44 AM no matter what the Locale is.
The code looks like:
rep.setTemplate(Templates.reportTemplate.setLocale(res.getLocale()));
...
if (rs.getString(i).contains("00:00:00"))
rep.addColumn(col.column(title, name, type.dateType()));
else
rep.addColumn(col.column(title, name, type.dateYearToSecondType()));
Is there a way to automatically format dates regarding to the Locale of the report or have I to use a custom ValueFormatter?
I also tryed the Parameter Map with no success
JasperReportBuilder rep = report()
.setDataSource(query, conn.getConnection())
.setParameter(JRParameter.REPORT_LOCALE, res.getLocale());
.setTemplate(Templates.reportTemplate.setLocale(res.getLocale()));
There is no way to automatically format the dates.
The only way is to use patterns for the date column in respect to the locale.
TextColumnBuilder<Date> column = col.column(title, name, type.dateType());
if (res.getLocale().equals("EN") {
column.setPattern("dd.MM.yyyy");
}
else if (res.getLocale().equals("US") {
column.setPattern("MM/dd/yyyy");
}
else {
...
}
rep.addColumn(column);
I managed to format the date field in dynamic jasper in this way.
ColumnBuilder time = ColumnBuilder.getNew();
time.setTitle("Login Time");
time.setWidth(200);
time.setColumnProperty("emp.logintime", Date.class.getName()).setPattern("dd/MM/yyyy hh:mm:ss a");
drb.addColumn(time.build());
