Need help on data coversion to be read by Java program

Hello everyone,
I have a challenging project to generate reports from MVS (mainframe) data and using Java as the programming language to read this data and generate reports. The Java program will execute on Wintel platform and AIX/UNIX platform.
The data that I need to read (DCOLLECT idcams utility) is in binary/EBCDIC variable record format and resides in mainframe and transmitted via FTP to wintel platform.
I tried converting the data to ASCII format before tranferering but the transfered data seems to be wrapped around and not sure how to handle it. I could transfer the whole thing in binary format and then read and convert at the same time( I believe Java can read EBCDIC accoding to my notes).
I am sure some one have done this once before and I do not want to reinvent the wheel againg. I need your help in what direction to take for best aproach reading this data.
Your suggestions would be appreciated
Thanks

Thanks for you replies guys!
I need to use java because the ultimate reporting tool
is going to be a service developed in Jini.
The reason I believe the data seem to be wrapped
around after ftp transfer is because when I edited
(TSO FSE from MVS) all text data is aligned withing
the same column.
After data is transmitted via FTP (converted to ASCII
during trasmition) and edited with wordpad, text
characters do not seem to be on the same possition.
They are scattered all over the display area. Is
possible this could be a display affect from winword
but not sure.
The MVS job to FTP the file follows:
//STEP01 EXEC PGM=FTP,
// PARM='FTP.MIAMIDADE.GOV (EXIT'
//SYSPRINT DD SYSOUT=*
//OUTPUT DD SYSOUT=*
//SYSIN DD *
user-name/password
CD /storage
CD UAL
ASCII
PUT 'STORAGE.DCOLLECT.TYPV' 'DCOLLECT_TYPEV.TXT'
ls -l
close
quit
Words of advice appreciated

YES! 1st mistake ... don't use WordPad for this ... your NotePad, Dos, or some other pure text editor.

Need help in date coversion

Hi,
I have a date format which is varchar2 and value is like 2009-03-31..i need to convert to date and it shouldbe like 31-MAR-09
i am getting like 0RA-01981 error..please help me in that

What are you doing with your "date" once you've converted it? Storing it in a DATE column in a table? Using it as part of a date calculation?
You ONLY need to worry about the format of a date when:
a) you are telling the database your string is actually a date (ie. on input into the db)
or
b) you are selecting date information to display to the front end/report
Once a date-string is in DATE format, it's stored in Oracle's internal date format. Since we're humans, it's difficult for us to understand that format, so anytime we view a date, it goes through a translation back into a string for display purposes only.
This can be done via two ways:
1) to_char(your_date_col_or_var, your_date_format) to set the format explicitly, eg: to_char(sysdate, 'dd/mm/yyyy')
or
2) using the default nls_date_format parameter. This can be changed, eg: "alter session set nls_date_format='dd/mm/yyyy hh24:mi:ss';"
If that doesn't help you, please provide more information on what you're doing, including sample data and/or code.

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.

Hi,
You'll need to get javascript date from LCD field, and calculate & compare with the future date in javascript date.
try following script;

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.

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!

I need help restoring data from my time machine.

1) On the time machine, where do I find the TRASH file that is located on the dock in my desktop? I'd like to restore that to a prior date but can't find it.
2) I DID A VERY BAD THING & need help to get back to where I was before. I wanted to delete files that were taking up lots of space. My OTHER section was using 160G. I downloaded OmniDiskSweep and found that 120G was being used by my virtual machine (I run Quicken in Windows, through VMware). I started to delete files that were called Snapshots assuming these were the snapshots that the program regularly takes of my files. Apparently they were not. I also deleted the program Windows XP Professional because that was never used. When I try to open VM or quicken program, it says it is missing a particular snapshot, i.e. Snapshot 11104. I deleted about 20 of these. I left all the other files that said Windows XP Home Edition. But now it shows that I only have the Professional Edition, even though that's what I deleted. I'm trying to restore from Time Machine and it looks like the information is not there - I've tried various different backups and nothing seems to have the information I need. The earliest back up I have is from 5/7 when I started time machine on a new external 1TB HD. Would that have the information I need since it's the very first back up? Please Help.

I am assuming it's real data because it's taking up storage on my HD. It falls in the category "other" and the total of this section is 160G. Here is a snapshot of the virtual machine.
I also took a shot of the VM snapshots & it tells how much space is being taken up by the snapshots.
I've now changed the number of snapshots taken down to 12 (didn't know I had this option) & I can delete alot of the 21 snapshots that have already been saved. I have no idea how much of the HD was set aside for the VM because someone else installed it for me 5 years ago. I've had enough problems with it over the years that I've wanted to switch to Quicken for Mac or find another financial program to use. I've upgraded the VM 2x over the years, but didn't want to spend $100 for Version 5. I understand the concept of a VM but that's about all.
I did do the disk cleanup in Windows on the C drive. I deleted 700 MB of temporary files and then compressed 4G of data down to 2G. While the cleanup was progressing it said that the C drive was 30.99G and 78% of it was free. That just doesn't make sense to me. It recommended a defrag, so I did that also.
I'm pretty sure it's real data because I recently had to switch from a 320G external HD for TM, to a 1T HD. One TM backup was over 300G which I found to be excessive because I basically use my computer for mail, some word processing, and my financial data.
Thanks again for all your help. I really appreciate it.

Need help in date formatting

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:
Exception: java.text.ParseException: Unparseable date: "21/1/07"
Please help me....

Now as per the above error message format one is working fine but format 2(// Format Jan 21, 2007) have some issues...kind suggest.

Hi, My names Chance

i found a tutorial of exactly what i need to do but im stuck on creating a script to import and convert php data
to a single html line
heres the link to the the script, if you scroll down to the bottom
where it says
RSS or XML Data Source
"The scrolling text can be imported from any source: RSS, XML or any other format.
For example, if you want to import data using PHP to convert it into a single HTML line to be displayed by the ticker, create a php script to import and convert the data, and include it directly in the DIV tag as follow"
this is what i need help doing
http://www.mioplanet.com/rsc/newsticker_javascript.htm
i already have the php code that i want to import
i just need to know how to import and convert my php script so im able
to make the the javascript from the link i provided to work
thank you so much for your time
if you have any question or answer please email me
[email protected]
thanks again hope to here from you soon

Hi

Need help in date conversion(it's Urgent)

I am reading data from the text file... and inserting that data into the oracle table(using bpel process)
I have following problem with the date field.
In the XSD file if i specify the date format as nxsd:dateFormat="ddMMyyyy" and when i pass null value in place of date,partnerlink(file adapters read ) is not reading the data.
When i remove the dateFormat="ddMMyyyy in the xsd file then it is reading correctly and i am able to insert that data into the table.
Can anybody give me the solution to the above problem

from information you've given i'm concluding that
You've tried reset (*#7370#)
Ensured that you've successfully upgraded, i mean you didn't suffer a failed upgrade(*#0000#)
Though NSU uses user data conservation technology, you might've lost settings, which i'm sure you've checked and its there and selected correctly.
As the problem started after firmware upgrade and glitch seems to be with connectivity(i remember browser improvement was one of changelog of last update), so your phone somehow didn't get upgraded properly. Only way out is to consult nokia care in your city.

Need help detecting data changes in my jTable

I have created a jTable and a corresponding TableModel that extends the AbstractTableModel.
In my TableModel, I call fireTableCellUpdated within setValueAt.
I want to be able to say "if jTable has been edited then do something".
How do I do this? Do I have to implement an action listener? If I do then where do I implement that?
I've read the tutorial and the help several times but the tutorial is just a brief overview and does not go into what to do when you have extended the AbstractTableModel.
TIA,
Jennifer

I'm pretty much a novice to Java programming so I don't know why I'm using a custom table model. I'm just following my predecessor. My app has to be able to edit a .dbf file so I thought the table model has to be able to read the headers.
I've tried the code from the link you referenced and things are working great now.
Thanks again!

After user has make his selection by entering the qty and ticking on the check box, he would click the "Add To Cart" button ... and this would call my servlet : AddToAddControlSerlvet.java

import java.util.*;
import java.util.ArrayList;
public class AddToCartControlServlet extends HttpServlet
 public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException,IOException

 if (action.equals("AddToCart"))
 addToCart(req,res);
 public void addToCart(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
 try
 String url = "";
 String[] addList = req.getParameterValues("checkbox");
 HttpSession sess = req.getSession(true);
 //String sessionID = sess.getId();
 DBClass dbClass = new DBClass();
 ArrayList cartList = new ArrayList();
 for (int i = 0; i < addList.length; i++)
 String productCode = (String)addList;
 int qty = Integer.parseInt(req.getParameter("Q"+productCode));
 Products product = dbClass.getProductDetail(productCode);
 double totalUnitAmt = qty * product.getUnitPrice();
 double totalCartonAmt = qty * product.getCartonPrice();
 Order order = new Order(product.getProductCode(),product.getProductDesc(),product.getBrandName(),product.getUom(),qty,product.getUnitPrice(),product.getCartonPrice(),totalUnitAmt,totalCartonAmt);
 cartList.add(order);
 sess.setAttribute("cartList", cartList);
 url = "/Cart/CartDetails.jsp";
 ServletContext sc = getServletContext();
 RequestDispatcher rd = sc.getRequestDispatcher(url);
 rd.forward(req, res);
 catch (Exception e)
 System.out.println(e);
From here, i would get the list of items which user has selected and add to the cartList, then i would direct the user to CartDetails.jsp which displayed the items user has selected.
From there, user would be able to remove or to continue shopping by selecting other category.
How i do store all the items user has selected ... everytime he would wan to view his cart ...
As i would be calling from jsp to servlet .. or jsp to servlet ... and i do not know how i should go about in creating the shopping cart.

Hi !
Yon can use a data structure as vector and store the items selected by the user into the vector . Keep the vector in session using session object , so the user can access the entire shopping cart from anywhere in the application .
Then , you can change the cart accordingly .
Hope this works.
Cheers ,
Pranav
