can some one help me, why i am getting different month day and year
Be aware that you're using deprecated methods of the Date class. If you read the javadoc for those methods you'll discover that the results are correct. The getMonth method returns a zero-offset month with zero representing January. The getDay method returns a zero-offset day of the week (0 = Sunday...6 = Saturday) not the day of the month. Use the getDate method to return day of the month. The getYear method returns a value that is the result of subtracting 1900 from the year.

Urgent need help in data archeiving
hi to all,
i had a problem in data archeiving. the problem is i want to archive data from two tables
and also delete that data after a specific time. i got standard programs for it like sbooka and sbookd
one is for addition of record and other is deletion of records. but how to go forward with these standard programs i am not understanding ok plz help me in this issue
Thanks and Regards
Kranthi Kiran ReddyHi,
1) Create a archive object for ur program using
AOBJ transaction by specifying tables to be
archived. DAta is stored in table Arch_obj.
Also specify new delete,read program name.
create archive info structure,field catalog also.
Study EXAMPLE archive object and proceed.
2) First read archive data similar to program
sbooka by changing archive object name.
archive file will be created and stored in table
admi_run,admi_files.
3) Write delete program similar to sbookD to delete
data from your z custom table.
4 ) SARA transaction can be used to schedule
job.
5) SARI transaction can be used to view archived data.

Need help in date Validation Urgent
Hi ,
We need help in Date Validation.
we have 2 Date fields on the form Start Date, End Date
The requirement is: End Date (May not be greater than 30 years from the start date).
I have written following script on End Date Exit event. But the problem is its calculating 30 years from the Current Date not from the Start Date
var tDate = util.scand("mm/dd/yyyy", new Date());
var M = tDate.getMonth();
var D = tDate.getDate();
var Y = tDate.getFullYear();
var SRes = util.printd("yyyy-mm-dd", new Date((Y+30), M,D) );
//app.alert(SRes)if (SRes <= this.rawValue){
app.alert("May not be greater than 30 years from the start date")
xfa.host.setFocus(
this);}
can someone please help me
Regards,
JayHi,
You'll need to get javascript date from LCD field, and calculate & compare with the future date in javascript date.
try following script;
var sDate = StartDate.rawValue;
var wkStartDate = util.scand("yyyy-mm-dd", sDate);
var nYear = wkStartDate.getFullYear();
var nMonth = wkStartDate.getMonth();
var nDay = wkStartDate.getDate();
var wkFutureDate = new Date(nYear + 30 , nMonth, nDay);
sDate = EndDate.rawValue;
var wkEndDate = util.scand("yyyy-mm-dd", sDate);
if (wkEndDate.getTime() > wkFutureDate.getTime()){
xfa.host.messageBox("May not be greater than 30 years from the start date");
xfa.host.setFocus(this); -

When I compile this in Flex Builder 3 it says: The element type 'mx:Application' must be terminated by the matching end-tag '</mx:Application>'.
but I have this end tag in my file, but when I try to switch from source view to desgin view it says, that: >/mx:Script> expected to terminate element at line 71, this is right at the end of the .mxml file. I have actionscript(.as) file for scripting data.
This is the mxml code to terminate apllication tag which I did as you can see:

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. -

Don't flag your question as urgent, even if it is for you.
* We all answer questions here voluntarily, in our leisure time. We do that because doing so is fun for us, because we enjoy helping people and having interesting discussions. Guess what, it is much less fun if it gets stressful. So the last thing you want to do to get us to answer your question is to pass your stress over to us.
* People who are stressed and want a fast answer often don't even find the time to do the necessary research or to formulate their question in an easy to comprehend way. That's even less fun to work with. So you really don't want us to feel your stress. Instead you want to take your time to write a well formulated post that is fun to answer. The less likely it is for us to know that your question is urgent, the more likely you are to get a fast answer!
* The simple notion that you want your post to be answered faster than those of the other members might feel rather unfair to some of us. Doubly so because often "urgent" questions actually are homework questions. Yours might be different, but someone who had bad experiences with this type of question might not read far enough to notice. -

[Urgent] Need help calculating difference between two dates
I'm trying to write a code to display the current day and time, then accept two dates from the user and display the difference between the two dates. To display the current date and time, I've used the SimpleDateFormatter library but I'm having difficulty calculating the difference between two dates. Could someone please help me with this?
Below is my code so far
import java.util.Date;
import java.util.Scanner;
import java.text.SimpleDateFormat;
public class DateFormatter {
public void displayNow()
Date todaysDate = new Date();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss");
String formattedDate = formatter.format(todaysDate);
System.out.println("Today's date and time is: "+formattedDate);
public void calculateDifference(Date startDate, Date endDate)
/* This is whre i need help! */
public static void main(String[] args)
DateFormatter df = new DateFormatter();
Scanner sc = new Scanner(System.in);
df.displayNow();
System.out.println("Please enter a date: ");
String date1 = sc.next();
System.out.println("Please enter another date: ");
String date2 = sc.next();
}The methods displayNow() and calculateDifference(Date startDate, Date endDate) are essential and cannot be skipped out.tarahmarie101 wrote:
Dude. I've tried doing assignments under pressure, and it doesn't work. Here's a piece of free advice. Start earlier next time, don't put "urgent" in the title of your post b/c it just pisses people off around here--and is a sure sign of an overdue homework assignment which no one around here likes helping with, and try to ask intelligent questions--don't just say "Help me!"
Of course, it takes some time to learn what the intelligent questions are. You have my sympathy. Try asking questions about how to do a particular task, instead of asking people to tell you what to do. It starts to get easier after a while.
actually dude i started on this on monday.. but there were so many other stuff to do along with this.. and i did try referring up the Calendar utility but it was a bit confusing actually.. it was only after that did i come to this forum.. nor am i very good at Java.. anyhoo thanks for your sympathies :P -
URGENT: Need help reading URL of current page
Hello kind people!
I need help, and its very simple:
How do i read the URL of a web page?
For example, the URL of this page is:
http://forums.sun.com/thread.jspa?threadID=5327796
So how can i be able to read in this URL in my java program?
thanks SO MUCH
P.S. I HAVE searched the java docs and everything, the closest thing i found was request.getRequestURL().? but i have no idea how to use it. you have NO IDEA how appreciative i would be if you could simply show me exactly how to read in the URL of a given page.
thanks SO MUCH

This expects the "page" to be text (hence an InputStreamReader instead of an InputStream.)

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. -
Hi,
I need to print date in the following format:
Jan 21, 2007
11:23 AM 21/01/2007
21-01-2007 18:23
Now as per condition of assignment the year, month, day and hour, min, sec all are entered as separate integer values.
my code:
import java.util.*;
import java.text.*;
public class stringToDate
// Integer value of date and time variables
int day=21;
int month = 1;
int year=07;
int hour=18;
int min=23;
int sec=14;
// Converting integer value into date
public void convertIntoDate()
String strTmp= day+"/"+month+"/"+year+" "+hour+":"+min+":"+sec;
System.out.println("String: " + strTmp);
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
try
Date outDate = dateFormat.parse(strTmp);
System.out.println("Converted: " + dateFormat.format(outDate));
catch(Exception e){ System.out.println("Exception: " + e);}
public static void main(String args[]) {
stringToDate dF = new stringToDate();
dF.convertIntoDate();
}Now as per my code i am able to print in the following format:
String: 21/1/7 18:23:14
Converted: 21/01/0007 18:23:14
But if i try to print in other formats it gives me following error message:

Need help with a Class.
Ok hey guys i got A project for school and i need help. I asked my teacher and he num so yea. here it is
this is my blog class
/* Project Name: .java
Name:
Class: Programing 2 #0047-02 Pds 5&6
Variable List:
Info:
import java.util.Scanner;
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
public class blog
String date2;
String user;
String Entry;
public void GetInfo(String Iuser,String IEntry)
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
date2 = dateFormat.format(date);
user = Iuser;
Entry = IEntry:
public void ShowInfo()
System.out.println(date2 + " " + user + " Said: " + Entry);
}This is my test class
/* Project Name: .java
Name: Josh
Class: Programing 2 #0047-02 Pds 5&6
Variable List:
Info:
import java.util.Scanner;
public class test
String user;
String Entry;
public static void main (String[] args)
{ System.out.println("Welcome Please Eneter UserName");
Scanner kb = new Scanner(System.in);
user = kb.next();
System.out.println("Please Enter Your Entry");
Entry = kb.next();
blog info = new blog();
blog.GetInfo(user,Entry);
blog.ShowInfo();
}So what is sopost to do in the test it ask user to import user name and entery. It send it to blog Class, then it send it out. Here is my errors
G:\VOC T2\Java\Chap4\test.java:21: non-static variable user cannot be referenced from a static context

Tool completed with exit code 1 Plez help-- "non-static X cannot be referenced from a static context" --
You get this error because static members don't require an instance of the object to be accessed; they belong to the class. But a non-static member belongs to an instance (an individual object). There's no way for the static method to know which instance's variable to use or method to call, and thus, the compiler happily tells you that you can't access an instance member (non-static) from a class context (static).

Below is the XML and need help in parsing it
declare
responsexml sys.XMLTYPE;
testparsexml sys.XMLTYPE;
begin
responsexml := sys.XMLTYPE('<GetListItemsResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/">

The issue is with rs:data , z:row nodes.... please suggest how to handle these kind of namespaces in Oracle
I need the parse the attribute "ows_Title" and save it into a DB

Need help with date range searches for Table Sources in SES
Hi all,
I need help, please. I am trying to satisfy a Level 1 client requirement for the ability to search for records in crawled table sources by a date and/or date range. I have performed the following steps, and did not get accurate results from Advanced searching for date. Please help me understand what I am doing wrong, and/or if there is a way to define a date search attribute without creating a LOV for a date column. (My tables have 500,00 rows.)
I am using SES 10.1.8.3 on Windows 32.
My Oracle 10g Spatial Table is called REPORTS and this table has the following columns:
TRACKNUM Varchar2
TITLE Varchar2
SUMMARY CLOB
SYMBOLCODE Varchar2
Timestamp Date
OBSDATE Date
GEOM SDO_GEOMETRY
I set up the REPORTS table source in SES, using TRACKNUM as the Primary Key (unique and not null), and SUMMARY as the CONTENT Column. In the Table Column Mappings I defined TITLE as String and TITLE.
Under Global Settings > Search Attributes I defined a new Search Attribute (type Date) called DATE OCCURRED (DD-MON-YY).
Went back to REPORTS source previously defined and added a new Table Column Mapping - mapping OBSDATE to the newly defined DATE OCCURRED (DD-MON-YY) search attribute.
I then modified the Schedule for the REPORTS source Crawler Policy to “Process All Documents”.
Schedule crawls and indexes entire REPORTS table.
In SES Advanced Search page, I enter my search keyword, select Specific Source Group as REPORTS, select All Match, and used the pick list to select the DATE OCCURRED (DD-MON-YY) Attribute Name, operator of Greater than equal, and entered the Value 01-JAN-07. Then the second attribute name of DATE_OCCURRED (DD-MON-YY), less than equals, 10-JAN-07.
Search results gave me 38,000 documents, and the first 25 I looked at had dates NOT within the 01-JAN-07 / 10-JAN-07 range. (e.g. OBSDATE= 10-MAR-07, 22-SEP-07, 02-FEB-08, etc.)
And, none of the results I opened had ANY dates within the SUMMARY CLOB…in case that’s what was being found in the search.
Can someone help me figure out how to allow my client to search for specific dated records in a db table using a single column for the date? This is a major requirement and they are anxiously awaiting my solution.
Thanks very much, in advance….raford,
Thanks very much for your reply. However, from what I've read in the SES Admin Document is that (I think) the date format DD/MM/YYYY pertains only to searches on "file system" sources (e.g. Word, Excel, Powerpoint, PDF, etc.). We have 3 file system sources among our 25 total sources. The remaining 22 sources are all TABLE or DATABASE sources. The DBA here has done a great job getting the data standardized using the typical/default Oracle DATE type format in our TABLE sources (DD-MON-YY). Our tables have anywhere from 1500 rows to 2 million rows.
I tested your theory that the dates we are entering are being changed to Strings behind the scenes and on the Advanced Page, searched for results using OBSDATE equals 01/02/2007 in an attempt to find data that I know for certain to be in the mapped OBSDATE table column as 01-FEB-07. My result set contained data that had an OBSDATE of 03-MAR-07 and none containing 01-FEB-07.
Here is the big issue...in order for my client to fulfill his primary mission, one of the top 5 requirements is that he/she be able to find specific table rows that are contain a specific date or range of dates.
thanks very much!
