Help with Date objects

          I need to get the current date from within a JSP and insert it into an
          Oracle database.
          I need the form to be DD-MON-YY.
          What is the recommended approach for this? I have been experimenting with
          time conversions and etc.. but it gets to cludgy. There must be an easier
          way.
          Thanks,

See the data formatting classes in java.text ... what you need is there.

Need Help with Dates

I am printing a calendar and certain events will be helds on certain dates.
One can edit the event if it has not passed the date. Events in the past can be viewed but not edited.
When I query the database the date must be formatted dd-MMM-yy
I am able to get today's date by doing this:
java.util.Date today = new java.util.Date();
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
String today_str = sdf.format(today);
My code for printing the calendar: I left out some of the table formatting in the JSP page.
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int month = d.get(Calendar.MONTH);
d.set(Calendar.DAY_OF_MONTH,1);
int weekday = d.get(Calendar.DAY_OF_WEEK);
for(int i = Calendar.SUNDAY; i < weekday; i++)
out.print("<td> </td>");
do {
int day = d.get(Calendar.DAY_OF_MONTH);
out.print("<td>" + day + "</td>");
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
if(weekday == Calendar.SATURDAY)
out.println("</tr><tr valign=top>");
d.add(Calendar.DAY_OF_MONTH,1);
weekday = d.get(Calendar.DAY_OF_WEEK);
} while(d.get(Calendar.MONTH) == month);
if(weekday != Calendar.SUNDAY)
System.out.println();
The part I need help on is this:
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
I'm looping through each day of the month to print the days. I have the month, day, year as integers. How can I create a date object out of that and compare it to today's date to test if it's before or after today???
All the function in the Date class that I think would do this have been deprecated.

Need Help with Dates
Here is some information about dates:
There are many edible palm fruits, and one of the most widespread and favored of these is the data (Phoenix dactylifera). Dates were cultivated in ancient land from Mesopotamia to prehistoric Egypt, possibly as early as 6000 B.C. Then--as now--dates were a staple for the natives of those dry regions. Much later, Arabs spread dates around northern Africa, and dates were introduced into California by the Spaniards in 1765, around Mission San Ignacio.
The date prefers dry, hot climates, because date fruits are injured at temperatures of 20 degrees F, and the damp climate of the California coast was not favorable for fruit production. In the mid-1800s, the date industry developed in California's hot interior valleys and in Arizona. Now the date industry in the United States is localized mostly in the Coachella Valley, where the sandy soils permit the plants to be deeply irrigated. Today the new varieties, mostly introduced in this century, produce about 40 million pounds of dates per annum, or over 60% of the dates consumed in this country. The rest are imported mainly from Persia. According to one survey, about one million people are engaged entirely in date palm cultivation worldwide.
Hope that helps.

Is there a Java utility class to help with data management in a desktop UI?

Is there a Java utility class to help with data management in a desktop UI?
I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
someone recommended JGoodies Bindings for Swing - will this work well and in FX?

Many thanks for the reply.
In the servlet create an Arraylist and in th efor
loop put the insances of the csqabean in this
ArrayList. Exit the for loop and then add the
ArrayList as an attribute to the session.I am making the use of Vector and did the same thing as u mentioned.I am using scriplets...

In the jsp retrieve the array list from the session

You can do this in a scriptlet but should also check

Need Help with data type conversion

Hello People,
I am new to java, i need some help with data type conversion:
I have variable(string) storing IP Address
IPAddr="10.10.103.10"
I have to call a library function which passes IP Address and does something and returns me a value.
The problem I have is that external function call in this library excepts IP Address in form of a byte array.
Here is the syntax for the function I am calling through my program
int createDevice (byte[] ipAddress).
now my problem is I don't know how to convert the string IPAddr variable into a byte[] ipAddress to pass it through method.

Class InetAddress has a method
byte[] getAddress() You can create an instance using the static method getByName() providing the IP address string as argument.

Help with date validation on input boxes.

I need some help with date validation on input boxes.
What I�m trying to create is a form where a user inputs dates and then the rest of the form calculates the other dates for them.
i.e. � A user inputs 2 dates (A & B) and then a 3rd date which is 11 weeks before date B is calculated automatically.
Is this possible and if so how do I do it ???
Thanks

Hi,

Need some help with date

Hi everyone!
I have an application in Flex AIR and I'm having problems with dates, I could't found an example on internet until now.
I tried this for insert (database is embeded sqlite)
insertManager.parameters[":mydate"] = mydate.selectedDate.time; // type of this column is INTEGER (in my table) and store a number (milliseconds from 1/1/1970) ex: 1265079600000
Then when I need read records
mydate.selectedDate = new Date(mydateprice); //it supposed show me DD/MM/YYYY but in every case display 1/1/1970
If I replace mydateprice for mydate.selectedDate = new Date(1265079600000); // it brings me the right date
So I don't know what happed, and I'm not sure if it's the best idea to store a date in Flex AIR
I'll appreciate any help, information or example to find a solution.
Regards!
Mara.-

Thank you so much VIKASH!!! it works!!!
Now I'm trying to format this value 1265079600000 in my datagrid column:
<mx:DateFormatter id="dateFormatter" formatString="DD/MM/YYYY"/>
<mx:DataGridColumn width="140" textAlign="left" headerText="DATE" dataField="myDateColumn" labelFunction="formatDate" />
public function formatDate(item:Object,column:DataGridColumn):String
return dateFormatter.format(item.myDateColumn);
but this column appear empty....
Regards and thanks again!

Problem with Date objects

I have a problem when using Date objects. If i create a Date object like this:
Date d = new Date( 2002,03,20,19,45 ), and i try to get the number of Milliseconds
( d.getTime() ) i get a number that cannot be correct. I't is to high. I't looks like i
get the number of Milliseconds to year 3000+ ?? But if i write out the Date object
using a DateFormat.getInstance(), the date is equal to the date i entered above!
Can anybody help me with this ?? Please ??

Hi... as far as I remember, the getTime method returns the number of milliseconds since January 1 1970 (a holdover from Unix days).

Well first off you have your string mixed up, month comes
before date. So that should be
var isToday:String = thisDate.getMonth().toString() + "/" +
thisDate.getDate().toString() + "/" +
thisDate.getFullYear().toString();
Then the second thing to take note of is something straight
out of the live docs with the month.
month : Number
The month (0 for January, 1 for February, and so on) portion
of a Date object according to local time.
They start at 0 not 1. So you have two options either always
add one to the month for the correct month if showing the number
like that or format the date using a DateFormatter before you alert
it. Which could be done like so.
var df:DateFormatter = new DateFormatter();
df.formatString = "MM/DD/YYYY";
Alert.show(df.format(new Date()), "Full Date");
Hope this helps.

Help with date formatting.

Hi,
I have been asked to fix a problem with a report. I have found that the problem is the date format being passed to the stored procedure is not correct, The current format is like Mon April 04 2007. The correct format should be DD-MMM-YYYY which I take to be Mon Apr 04 2004. I am not sure if this is correct anyway, but after looking at the code and the api I have managed to create a date object and call toString on it, after setting a simple date format to dd MMM yyyy.
The problem is that the toString method returns Mon Apr 02 00:00:00 BST 20
07. Is anybody able to help me with this? Below is a little bit of the code:
public void renderDailyReport(ServletWriter out, HttpServletRequest request) throws Exception {
        // reset counters
        totalHits    = 0;
        maxHits      = 0;
        minHits      = 0;
        // get a GregorianCalendar object using the startDate and endDate Strings
        SimpleDateFormat sdf         = new SimpleDateFormat("dd MMMM yyyy", Locale.UK);
        SimpleDateFormat procedureDateFormat = new SimpleDateFormat("dd MMM yyyy", Locale.UK);
        GregorianCalendar dateCounter = new GregorianCalendar();
        GregorianCalendar upperLimit = new GregorianCalendar();
        sdf.setCalendar(Calendar.getInstance());
        Date sd = sdf.parse(startDate);
        Date ed = sdf.parse(endDate);
        procStartDate = procedureDateFormat.parse(startDate);
        procEndDate = procedureDateFormat.parse(endDate);The procStart and end dates are the bits that I added.
They are passed to the stored procedure calling .toString, they are date objects.
Appreciate any help.

Do not use the toString() method of Date - it will always be the same format.
Use the format() method of SimpleDateFormat.
Date d = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("'dd-MMM-yyyy"); // or something like this
String s = sdf.format(d);Message was edited by:

Help with Data Matrix (2D) barcode

Hey everybody,
I need a little help with creating a dynamic Data Matrix barcode. The DM Studio help files explain the barcode, regions, data code words, etc, but don't really help with implementation of one. I can create a static one using the actual Barcode widget in DM Studio, but I'm unsure how to create a dynamic one. Minimally I'd need to change the barcode's content from document to document, but if you use the barcode object in your section, it doesn't appear as though it allows variables or variable information (i.e. DAL script results). We have 3 of 9 barcodes, but we create those by simply using the 3of9 font when outputting the barcode's content. With the Data Matrix barcode, that doesn't seem like the appropriate course of action because of additional attributes like Scale or Symbol Size.
Thanks,
Gregg

Hi Gregg,
I would request you to try like this.
1. First insert a normal field (not a bar code).
2. Change 'Type' to Barcode.
3. Change 'Format' to Data Matrix.
4. Change 'Length' to 11.
5. Change Symbol size, Scale appropriately.
6. Use Rule as usual you would do for a normal field.
7. Use Data Matrix bar code fonts (13504, 13505, or 13506) which are included with Documaker. If you have any other specific font for Data Matrix bar code, you may try that as well.
These steps should allow you get a dynamic bar code.
Thank you.

Problems with Date objects

I want to use the HttpSession.getCreationTime() value and write it to an Oracle Date field.
I am having trouble getting the value in the proper type and format.
I have a test servlet to try to understand the various ways to use and convert DateTime values.
Here's the code:
response.setContentType("text/html");
java.io.PrintWriter out = response.getWriter();
HttpSession session = request.getSession();
long logontime = session.getCreationTime();
SimpleDateFormat formatter = new SimpleDateFormat("mm-dd-yyy hh:mm:ss");
java.sql.Date sqlDate = new java.sql.Date(logontime);
String sDate = formatter.format(sqlDate);
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet</title>");
out.println("</head>");
out.println("<body>");
out.println("DateTime in Milliseconds: " + session.getCreationTime() + "<br>");
out.println("DateTime as java.sql.Date: " + sqlDate + "<br>");
out.println("java.sql.Date SimpleDateFormat: " sDate "<br>");
out.println("</body>");
out.println("</html>");
out.close();
Here's the output:
DateTime in Milliseconds: 1016812138284
DateTime as java.sql.Date: 2002-03-22
java.sql.Date SimpleDateFormat: 48-22-2002 10:48:58
What's happening with the Month in the SimpleDateFormat output?
Also,
How can I convert this string into a valid Date Object to use in CallableStatement.setDate(int index, Date x)?
Thank you for your help.

If you have a String that's in that format, and you want to convert it to a java.util.Date, you do something like this:SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy hh:mm:ss");
java.util.Date date = dateFormatter.parse(thatString);Then if you want to convert that to a java.sql.Date, you do this:java.sql.Date sqlDate = new java.sql.Date(date.getTime());However, I suggest you don't actually want to do that. If your date has hours, minutes, and seconds in it then converting to java.sql.Date throws away that information. You may want java.sql.Timestamp instead.

Help with dates

Hello Everybody.
I need help with de management of dates in my sentence.
I execute the setence to extract information by dates range.
but i have a problem, because i need extract the information automatically, the first day of every month.
the information must be the all last month.
I dont know, what sentence use.
The objective is: refresh the date automatically every month.
This is an example of my sentence, but I need use the field AF_DATE too because this is of date of of production form my information:
The field af_dat is char.
WHERE EFM='F' AND AF_DAT BETWEEN 'date1' AND 'date2'
AND TO_CHAR(AF_TIM,'HH24:MI:SS') BETWEEN
'05:30:00' AND '23:59:59' OR
AF_DAT BETWEEN 'date1' AND 'date2'
AND TO_CHAR(AF_TIM,'HH24:MI:SS') BETWEEN
'00:00:00' AND '00:45:00'AND EFM='F'
ORDER BY AF_DAT,AF_TIM;
Edited by: user10827532 on Jan 23, 2009 7:07 AM

Hi,
It looks like you're using two columns, af_dat for the year-month-day, and af_tim for the hours-minutes-seconds.
A lot of folks would just use one column, and do the kind of range check you want like this:
WHERE   af_dat_tim >= TRUNC (ADD_MONTHS (SYSDATE, -1), 'MM')   -- Start of LAST month
AND     af_dat_tim < TRUNC (            SYSDATE,      'MM')   -- Start of THIS month
AND     TO_CHAR (af_dt_tm, 'HH24:MI') NOT BETWEEN '00:46'
                                           AND      '05:29'

Help with data load model

Hi,
I need help with a data load model. First, i'm doing delta extraction from R/3, we load data with a InfoSource to InfoCube A and InfoCube B.
I'm doing master data validation on the load, so if a load fails for InfoCube A, it fails for InfoCube B too (this is because i can have only 1 InfoPackage for the 2 infocubes, because of the delta update).
So i propose a new model in wich:
- The delta load is taked first to an ODS.
- ODS is cleaned before the delta update.
- Then i create 2 InfoPackages for full load from ODS to Infocube A, and from ODS to InfoCube B.
With this solution i can have 2 infopackages from ODS because i'm not doing a delta load from here to the cubes, and with 2 infopackages i can have independent validations for each cube so if one of them fails, the other can still be loaded sucessfully.
The solution fails because if i load delta from R/3 to the ODS i can't clean it first. The initialization and the old updates needs to be previuslly loaded on the ODS. Then i can't do full load to the cubes and neither have 2 infopackages.
Please help me to solve this issue.
thanks a lot

Hi jeremy,
what about this simple solution:
load data by delta from R/3 in your ODS. You can also have an ODS/cube for the historical data which is more space-saving than holding all the old data in PSA. Then you load your historical data from PSA into the historical ODS/cube.
From your ODS with the actual data you update your requests by full from ODS into the cubes with 2 different full infopackages. But because you load by full you have to use deletion selections in the infopackages to avoid duplicate data!
regards,
Jürgen
