Problemmmmmmmm with date? HELP!!!!!!!!!

Hi
In my program I want to print the current time in millisecond.
I works fine.Now I want to add 5 hours to the current time and display the time in millisecond.
I use this code
Calendar c=Calendar.getInstance();
System.out.println("Current time="+c.getTime().getTime());
Then Use this code to add 5 hours to the time
TimeZone tz=TimeZone.getTimeZone("GMT+5:00");
c.setTimeZone(tz);
System.out.println("New time="+c.getTime().getTime());
But I only get the same number of millisecond?ie current time and new time displays same number.
Could you please try this and tell me what is the problem?
Is there any other method to do this
Could you Please include a sample code
thanks
sabu

c.getTime().getTime() will always return you the number of milliseconds since January 1, 1970, 00:00:00 GMT. Changing the TimeZone in your Calendar will not affect this.
To get the actual time, use Calendar.get(Calendar.HOUR) for the hour, with similar commands for the minute, second etc. To add 5 hours to the Calendar time, you can use Calendar.roll(Calendar.HOUR, 5)

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
and in a for loop step through the ArrayList
retrieving each CourseSectionQABean and displaying.
You can do this in a scriptlet but should also check
out the jstl tags.I am able to remove this problem.Thanks again for the suggestion.

Help on export sybase iq tables with data and import in another database ?

Help on export Sybase iq 16 tables with data and import into another database ?

Hi Nilesh,
If you have table/index create commands (DDLs), you can create them in Developper and import data using one of methods below
Extract/ Load table
Insert location method : require IQ servers to be entered in interfaces file
Backup/Restore : copy entire database content
If you have not the DDLs, you can generate them using IQ cockpit or SCC.

Transfer Of Data from Sap to Oracle with the help of Enterprise Services.

Hello,
We want to transfer data from Sap to Oracle using standard Enterprise Services.Some fields were not available in the existing standard Enterprise Services,so we have enhanced the existing Services by writing code inside BADI available with Enterprise Services.Rest of the fields we have mapped with the existing fields available in standard Enterprise Services.But,the Oracle people want to fetch all data from Sap without entering any input as a mandatory field in the Enterprise Services.The existing standard Enterprise Services require to enter any field as mandatory and are not accepting the range in input for multiple records.e.g.All enterprise Services related to Sales Orders are displaying only one sales Order.We have searched all Enterprise Services for Sales Order(related to reading of data),but not able to find service which would display mutiple records without entering any input.ECC_SALESORDER009QR is the only service which is displaying multiple records without entering any input,but the required fields are not available in this service.So,kindly suggest what we need to do further.
1.Should we go for customization of services completely,so that it would fulfil our requirement.
2.Are there standard Enterprise Services exists which would we give us data in range(all records).
If they exists,please specify the names of Services for reading Purchase Order,Production Order,BOM etc.
Thanks & Regards,
Divya.

Hi Vaibhav,
Let me tell you the objective in detail.
Objective.
To develop a package solution which will work as a bridge between Oracle APS and SAP system so that customers using SAP will be able to use advantages of Oracle APS for their planning needs.
This will consist of following major components:
OA Templates is an Oracle utility to load data from any legacy system to Oracle APS using standard flat files.
Oracle has developed an Application Integration Architecture which is a standard architecture used for integration of Oracle products with other systems.
Enterprise services is an SAP utility to communicate with SAP.
AIA canonicals are standard canonicals developed by Oracle where we have to map data fields from destination system (Oracle APS) and source system (SAP)
Fusion middleware is being used to develop application interfaces following AIA standards.
Tasks at stake:
Mapping of Oracle APS fields and SAP Enterprise Service fields to AIA canonicals
Technical work of developing middleware using Oracle Fusion
From Sap side,we have to map fields which we have received from Oracle with the help of Enterprise Services,rest consumption of these services is done by Oracle guys.So,suggest is there enterprise services available which would give us multiple records .
Thanks & Regards,
Divya.

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.

To upload a data into SAP Table with the help of RFC function in BODS

Hi,
Please provide me step-by-step solution to upload data into any SAP table with the help of RFC function in Data Services.
I have created RFC function that upload data into SAP table. RFC Function contains one table that has same structure as my database table.
In the data services how can i filled the table of RFC function, i am using this function in query transform of data services but it gives me error.
I am also follow link http://wiki.sdn.sap.com/wiki/display/BOBJ/BusinessObjectsDataServicesTipsand+Tricks
but it did not help me.
Thanks,
Abhishek

Hi Abhishek,
Did you import the function module in the SAP datastore first? When you open the SAP datastore, the function should be listed in the 'functions' section. If not, import it. Make sure your function is remote executable.
Once the function is there, you can use it in a transformation. In 'Schema Out' right-click on 'Query' (top level) and choose 'New Function Call'. You can then select a datastore and a function in the datastore. The wizard will show you which output parameters are available. I believe you have to add at least one and can select as many as you like.
After confirming your selection the function and the output parameters appear in Schema Out. You can then right-click on the function and choose 'Modify function call'. A popup will appear where you can specify the input parameters.
I hope this helps.

In Data Quality transform please explain Associate transform with the help of any example.

In Data Quality transform please explain Associate transform with the help of any example.

Hi Neha,
If we are using multiple match transforms and consolidate the final output we will use associate transform .
Let me explain with one example based on data quality blue prints for USA .
We have customer/vendor data .     We need to find the duplicates .
1. First we will find the duplicates on   Name and Address
2. Second we will find the duplicates on Name and Email
3. Third we will find the duplicates on Name and Phone
Here why we need to find the duplicates in multiple stages . If we are finding the duplicates on combination of Name, Address, Email and Phone we may not get proper duplicates   as we are finding the potential duplicates . That's why we are finding the duplicates on different combinations .
In this case we will get the different group numbers for each match combination . Each combination name is there .
We want to consolidate and give the group number to the whole set of duplicates . We will pass these 3 match groups to associative transform and generate the consolidated match group for the input data.
I hope you understand the concept .
Thanks & Regards,
Ramana.

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.

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!

Improving the LabVIEW Help: Working with Data Types

Have you ever had trouble figuring out how to work with the waveform data type, the dynamic data type, or some of the other more complex data types in LabVIEW? As a tech writer on the LabVIEW team, I'd like to improve our documentation about working with data. What would you like to see? What would be helpful? Have you ever given up on a particular data type because it didn't work? Have you ever created a replacement data type because you preferred not to use a LabVIEW data type?
Lacy Klosterman Rohre | Marketing Editor | National Instruments | 512.683.6376 | ni.com/newsletter

I've been programming LabVIEW since around 3.1 / 4.0. Over the years and versions, I've found it necessary to approach a lot of the new datatypes and algorithms with some healthy skepticism because I don't think we're usually given a "fair and balanced" overview. Some of the things that are highly promoted that bring "ease of use" for beginners (and I *do* understand the importance of that when you're growing your LabVIEW user base) can carry significant performance penalties that are mentioned in more of a whisper, if at all. I'd just like a more full disclosure of the tradeoffs -- the good, the bad, and the ugly.
Waveforms -- very rarely use them, unless required for analysis functions. I have a vague notion (between a belief and a memory) that they used to carry a significant performance penalty compared to arrays, but that the gap is now much smaller. Still, I'm most comfortable with my old habit of using data arrays. Some of this came about because a lot of my work uses counters where I may have a variable "dt" value or where my AI is clocked by a counter and the "dt" isn't internally generated.
Dynamic signals -- have never used them. Have no clear idea what good they're supposed to be, and they seem to be tied in primarily with Express VI's, which I have also studiously avoided.
Variants -- Use them only slightly. Performance issues are a question mark. Exception: have learned that the implementation of Variant properties allows their use as an efficient way to create associates for string lookup tables.
Digital Waveform -- have typically avoided it except when graphing digital data during debug. Haven't found any compelling reasons to use it. I do like the notion of a compress/expand capability for sparse digital data, but haven't exercised it enough to trust the implementation.
Recap: I don't need more simple "how-to's" in the help. I need a LOT more "why bother's" that include both pros and cons.

ZSearch Help: Unable to attach it with Data Element XBLNR1

Hi,
I made a ZSearch help, which will show the contents of one field of a Ztable.
There is a field XBLNR(Reference) with data element XBLNR1 in transaction FB50.
I want to attach Zsearch help with it.
I have the access key also, but when I am unable to attach Zsearch help with the data element XBLNR1 because it is not in editable mode.
Can anyone tell me the solution?
Or is there any other method with which I can attach Zsearch help with the screen field?
Regards,
Priyanka.

Hi Priyanka,
you can attach search help to the XBLNR element direclty.
GO to the program SAPMF05A screen number 1010 in SE51.go to layout and double click on doc.ref field. You can assign searhelp in attributes.
ofcourse , u need access key for this.
hope that helps.
regards,

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,
to get third date try this:
java.util.Date bDate = ...;
Calendar yourCalendar = new GregorianCalendar();
yourCalendar.setTime(bDate);
yourCalendar.roll(Calendar.WEEK_OF_YEAR, -11);
java.util.Date cDate = yourCalendar.getTime();Regards

Help With Date Manipulation

Hi Everyone,
I need help with oracle dates. I would like to format the following dates and keep it as a DATE datatype NOT char.
1/10/2007 8:57:45 PM TO 1/10/2007 (only the data part of SYSDATE)
1/10/2007 8:57:45 PM TO 1/1/2007 (first of the month)
If I use the To_Char function, it will return a character string. The problem is that I need to retain the DATE datatype so I can join this query to tables with date fields.

This?

Help with Data base

Hi all I am new in SUN Java Studio Creater and I having problem with
Data base can sombody help me how Can I create a data base.
I do not what I need to do that.
Is not come with Sun Java Studio or no.
if not which data base you think is the best to use with SUN java Studio
Creator.
Thanks alot

For a start, I guess you can explore the tutorial here:
http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/index.jsp?cid=113303
To create database, I guess, it's better if you use the tool provided by the database. Which database? It can work with any databases provided that you can find the JDBC driver for the database.
JSC2 is a great product. Just give it a try!
