JTabbed Pane help needed. Urgent Request.

Hello Folks
I have a question regarding tabbedPanes
In the Java Sun Site,there is an example of using JTabbedPane using an
example called DiveLog.
There is a line showing
tabbedPane.addTab("Welcome",
null,
new Welcome(),
"Welcome to the Dive Log");
This gives an error unless I say:
tabbedPane.addTab("Welcome",
null,
(Component) new Welcome(),
"Welcome to the Dive Log");
I am type casting Welcome() to a Component and this works fine!!!!
How can Java Sun give such an example??
Am I right in typecasting the class to Component as addTab expects
a component!!!
Please correct me if we can use new Welcome() as given in the example.

I don't know this example ... but if Welcome extends any Component there should be no need for a cast. Is the problem during runtime or during compile time? Maybe the cast satisfies the compiler, but not the JRE because Welcome does not extend any Component?
Rommie.

Some J2ME midlets doubts!! help needed urgently!!!

Hi,
I am currently working in a company where it does wireless technology like WAP and I am assigned a task of creating a screensaver midlet. I have some doubts on the midlets.
1) How do i use a midlet suites? From what I heard from my colleagues & friends, a servlet is needed for midlets to interact with one another. is it true?
2) How do I get the startin midlet to take note the phone is idling so that the screen saver midlet can be called?
Help needed urgently... if there is any source codes for me to refer to would be better... Thanks...
Leonard

indicates that MIDlet suites are isolated (on purpose) from each other, so you can't write over another one's address space.
Also, I believe (at least on cell phones) that you have to specifically enter the Java Apps mode; unless you do the app won't execute. If you are in Java apps mode and a call comes in, the cell's OS puts the Java app currently executing on "Pause" mode and switches back to phone mode.
Not sure if you will be able to have a Java app do that automatically.
BTW why do you need a screensaver on an LCD display? Is it really intended to show an advertisement?
Download and real all the docs you can from Sun, once you get over the generic Java deficiencies MIDlet's aren't that hard.

Help needed urgently on a problem..plzzz

hi..this is a linear congruential generator. I have to implement it and i need the execution time for the program.
for your understanding i'm providing an example below.
Xn=(( a* xn-1 )+b) mod m
If X0=7 ; a = 7 ; b =7 ; m=10
Then
X0 = 7
X1 =((7 * 7) + 7))mod 10 = 6
X2 = ((6*7)+7))mod 10 = 9
X3 = ((9*7)+7) mod 10 = 0
X4 = ((0*7)+7) mod 10 = 7
Now since the cycle is being repeated i.e 7 appears again�so the period is 4 coz there are 4 diff nos. i.e 7,6,9,0�..
help required urgently....your help will be appreciated...thankyou..

Hi,
I wrote the code so that it catches any cycle (not only the "big" one).
Otherwise it will enter infinite loop...
The time complexity is O(N*logN): it can do at most N iterations (here N is your 'm'), and in each iteration there can be O(log N) comparisons (since I maintain TreeSet).
Interesting issue: is it possible to supply such (x0, a, b, m) tuple such that all possible values from 0 to m-1 will be output? I think no :)
Here is the program:
package recurr;
import java.util.TreeSet;
import java.util.Comparator;
public class Recurrences {
     private static long x0, a, b, m;
     private static TreeSet theSet;
     public static void main(String[] args)
          long l0, l1, l2, l3;
          try {
               x0 = Long.parseLong(args[0]);
               a = Long.parseLong(args[1]);
               b = Long.parseLong(args[2]);
               m = Long.parseLong(args[3]);
          } catch(NumberFormatException nfe) {
               nfe.printStackTrace();
          System.out.println("X[0]: " + x0 + "\n");
          long curr = x0;
          boolean cut = false;
          int i;
          // initialize the set
          theSet = new TreeSet(new LongComparator());
          // we can get at most m distinct values (from 0 to m-1) through recurrences
          for(i=1; i <= m; ++i) {
               // iterate until we find duplicate
               theSet.add(new Long(curr));
               curr = recurrence(curr);
               if(theSet.contains(new Long(curr))) {
                    cut = true;
                    break;
               System.out.println("X[" + i + "]: " + curr + "\n");
          if(cut) {
               System.out.println("Cycle found: the next will come " + curr + "\n");
          } else {
               System.out.println("No cycle found!");
          System.out.println("----------------------------------");
          System.out.println("Totally " + (i-1) + " iterations");
     private static long recurrence(long previous)
          return (a*previous + b)%m;
     static class LongComparator implements Comparator
          public int compare(Object o1, Object o2)
               if(((Long)o1).longValue() < ((Long)o2).longValue()) {
                    return -1;
               } else if(((Long)o1).longValue() > ((Long)o2).longValue()) {
                    return 1;
               } else return 0;

Help needed Urgently- Rebate based on collected amount

Dear all,
I come across scenario while discussiion with client that they require rebate with collection. Details of the requirement are given below:
1. SAP rebates run on billed values & set the accrual in rebate agreement on the rate what we have specified in the rebate agreement. Requirement is that, If i have billed on 1000$ & my accrual value is 100$ with the rate of 10%. If i collected 800$ instead of 1000$, then i need to pay the accrual on the basis of 800$ not on the basis of 1000$. It means i have to adjust accrual amount on the basis of 800$. Conclusion is that i have to pay not 100$ accrual instead less then 100$ on the basis of 800$ which i collected.
2. In month 1 have billed on 5000$, my accrual amount is 500$ with rate of 10%. In the 2nd month i have to bill 1000$ and i have given an discount of 500$, it means my billed value is 500$ and my accrual amount is 50$@10%. In month 3 again i billed 500$ and my accrual amount is 50$@10%.
Requirement is that, when i am going to pay the accrual to client, i should pay correct accrual for which he is entitled for. Means i should pay 100$ accrual not 600$ because i have already given an discount of 500$. Discount which i have given already of 500$ should need to be offest with the first month accrual of 500$. So remaning accrual is 100$.
Great if somebody can help me out for the solutioning of the above requirements.

Thanks Ivano,
Somebody has started the conversation.
Let me put my questions again.
This requirement is nothing to do with Payment procedure in the agreement type.
1. In any month if i billed 1000$, so my account receivable would be 1000$. My rebate for that month is 100$ at the rate of 10%. During customer receipt if i collected against my invoice 900$ instead of 1000$, my accrual needs to be corrected 90$ instead of 100$.
I know this can not be fullfilled by standard SAP, by any thoughts on this welcomed.
2. I know Rebate can be settled partially or full settlement by payment method( by cheque, bank transfer, or by credit memo) we have configure in rebate agreement type. But here requirement is totally different.
Here, i need to pay the Rebate as a Discount instead of by cheque or by credit memo. While doing the partial or full settlement system will take into account collected accrual up to that day & apply as a discount to the final bill.
Scenario is like that sometimes customer asked to give us the discount on bill for whatever they accrued so far.
This is again cannot solved by standard SAP, but any thought by any body welcome. We have already thought that we need to enhance the solution.
Solution needed urgently.

Unable to allocate 27160 bytes.........Help needed urgently

hi
in my production database in getting this error..
ORA-04031: unable to allocate 27160 bytes of shared memory ("shared
pool","unknown object","sga heap(1,0)","session param values")
help needed urgently

If you have a program that does not use bind variables you can get this error.
In such cases you do not want to increase the size of the shared pool, but reduce it, and flush regularly. This is a bug in the application and should be fixed to use bind variables.
Another possible workaround is setting cursor_sharing = force, but this can cause other problems, so should only be used as a last resort. If the apps connections can be distinguished by user account or machine, then a log on trigger could be set cursor_sharing just for that application, to limit the damage until the vendor can fix it.

JOption Pane help needed! urgent

For a programming assignment in my AP Comp Sci class, we had to create a method (example: public int BlahBlah (int blah)). The instructions also say to use JOptionPane for inputing the int needed. However, because I created the method, it automatically brings up the method input box, AS WELL as the JOptionPane box I wrote in the code. So, essentially, I am getting two input boxes when all I want is the JOptionPane one.
Also, it is the JOptionPane number that I input that is used for the output.
How am I supposed to write a method but disable the method input box, and instead keep the JOptionPane box?
Any help is greatly appreciated

In the future, Swing related questions should be posted in the Swing forum.
1) Read the JOptionPane API description for an example;
2) Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html]How to Use Option Panes.

Product
? Name : String
? UPC : String
? Cost : Real
? Quantity : Integer
+ Product (Name : String, UPC : String, Cost : Real, Quantity : Integer)
+ Calculate Extended Cost() : Real
+ Calculate GST(): Real
Input Record:
Product name: String
UPC: String
Cost: real
Quantity: integer
Output Reports
1. Display of all product information including extended cost and GST including totals of these 3 fields.
Following is a sample of the output required:

Java coding requirements for this assignment
Main methods required
1.     Load array with all records. Display exception messages only for records that have invalid data in any of the fields. Return array of valid records and logical size.
2.     Validate the UPC. Display each report when requested from the menu.
3.     Justify the data in the columns. Right justify numeric fields; left justify the alpha fields.
4.     A method for each report required in the menu.
Class methods
5.     Use the object method for the extended cost.
6.     Use the object method for the GST.
You may use additional methods in the main program but do not add any methods in the class definition.
Use DecimalFormat for rounding.
Create an array to hold the objects. Assume that we only need to process a file of a maximum of 500 records but the file may be larger than 500 records.
A Universal Product Code consists of 12 digits. The first digit (from the left) is the UPC type. The next five digits are the Manufacturer code. The next five digits are the product code which is assigned by the manufacturer. The final digit is the check digit. A person can determine the check digit of a Universal Product Code by doing the following:
Step 1: Sum all of the digits in the odd positions together.
0+4+0+1+5+9 = 19
Step 2: Multiply the sum from Step 1 by 3.
3 * 19 = 57
Step 3: Sum all of the digits in the even positions together.
6+2+0+1+8 = 17
Step 4: Sum together the results from Step 2 and Step 3.
17 + 57 = 74
Step 5: Subtract the sum from the next highest multiple of 10.
80 - 74 = 6 [check digit]
TEST DATA:
Step 1: Create 5 or MORE additional records that will test all conditions. Include these in your documentation. Identify what field is tested in your test data. (Example: error in each field of the record, rounding up, rounding down, valid UPC, invalid UPC, formatting of report, file too large
Step 2: Use the file attached.
GODDDDDDDDDDDDDD lol pasting it made me go crazy,
these are my codes so far, HOwever the problem is ONLY DISPLAY MENU SHOWS, nothing else even though i have enough codes that it can show something,

Any help would be great thanks !!
Take care,

1) It's your problem that you waited until the last minute before you went for help...not ours. We'll give your problem the same attention as anyone elses...therefore your problem isn't any more urgent than any other problem here.
2) I don't intend on doing your entire assignment. Nor do I intend on reading all of it. If you need help with a specific requirement, then post the information/code relevant to that requirement. I don't know how to help you when you bury the problem inside a 9 mile long essay.
3) Post code in tags so it's formatted and readable. (there's a *code* button up above that makes the tags for you).

Help Needed to Request a Feature

Hello folks!
There is a feature I have been awaiting paitently for years,
ever since Conditional Build Tags came on the scene in RoboHelp.
Adobe has gotten closer than any of its predecessors at providing
this functionality, but just this week, I finally heard verbal
confirmation from Adobe that it doesn't yet do what I need it to
do.
I am appealing to you for help. It seems that the only thing
that will motivate Adobe to provide this (or any) functionality is
a preponderance of user requests on their Feature Request form. I
have already filled this out more than once over the years, to no
avail.
I have detailed below, in 1989 characters, just what I want
and why I want it. If you are moved to also request this
functionality, please go to
www.adobe.com/go/wish
select Feature Request, and if you want, simply copy and
paste my text below into the form. There is a 2000-character limit,
so I have tweaked the wording to make it all fit.
I have been drooling over this functionality for literally
YEARS, because I must maintain 5 separate projects in order to
provide my programmers with all of the different outputs (in
essence, different languages) that we need.
Thanks a bundle!

*******Enhancement / FMR*********
Brief title for your desired feature:
Apply Conditional Build Tags (CBTs) to Topic Titles Appearing
in Search Results
How would you like the feature to work?
Concise problem statement:
On all outputs, the Search Results list is being populated
without my CBTs being applied.
Steps to reproduce bug:
1. Create English & French CBTs.
2. Apply English & French CBTs to topic content,
including to the Topic Title, when displayed in the Design Editor
pane. (This must be done in the Design Editor pane, because CBTs
are not accepted by RH7 in the Topic Properties in the Topic Title
field.)
3. Create 2 new duplicate layouts, which use the English
& French CBTs.
4. Generate outputs for both English & French (WebHelp,
FlashHelp, HTMLHelp--it does not matter which one).
5. View the French output & go to the Search tab.
Results:
6. Search for a French topic title. The Help file does indeed
find the appropriate topic. However, the Search Results list
displays the ENGLISH topic title. If I display the associated topic
in the right-hand pane, I do see the French topic title there, as
well as the French content.
Desired results:
7. The Search Results list should display the FRENCH topic
title in the left-hand pane.
Why is this feature important to you?
No matter which language, our application is going to call
the same specific URL to fulfill a Help request. I use the Map ID
number in the Topic ID field. When I generate WebHelp output, each
topic will have a "Name.htm" which appears as "MapIDNumber.htm".
For instance, "388.htm" is the filename on WebHelp output for the
topic whose Topic Title is "View" in English & "Afficher" in
French.
This feature is important because RH7 will not allow the same
Map ID number or the same Topic ID to be used on more than one
source topic. I need to be able to apply the same Topic ID to
whatever language condition I want, and therefore, my one source
topic must contain all languages with their CBTs applied.

Hello, and thank you all so much for your interest in my
quest!
Since I have much to address, I will quote each person and
then reply to their comments. (Ooops! I have so much to say, I must
address each of your posts separately.)

I can see the problem this gives you but I am not sure it is
a bug.
Peter,
It's a bug in the sense that the output is not fully in
French, in every way possible.

Topic Properties and the Topic Heading, as at the top of your
topic.
Yes, you are right. In the Design Editor, I am editing the
topic title where the Heading style is applied. I suppose the
correct term for this item is indeed "Topic Heading."

It sounds like your layout is to have English content and
French content in the same topic and exclude whatever you need to
for a particular output.
In actuality, I use the Advanced button on the Layout to
Define my CBT Expression. I choose to INCLUDE my desired CBT by
Adding the Tag for a particular output.
For English, I would choose to INCLUDE my English CBT; for
French, I would choose to INCLUDE my French CBT.
In my world, there are multiple English names for the very
same widget. Therefore, I use multiple English conditions to
deterime which name should appear for a particular widget. I mark
the rest of the text with ALL of my English conditions, and mark
the French text with my French conditions. (I MUST mark the English
as English, simply because my source topic also contains French
text. This is the only way to leave the English out of the French
outputs.)
Now, imagine that I want to output just one of my English
conditions. If I were to use Exclude for all of the other English
conditions, then the very text that is marked for all of my English
condtions would never make it into my output.
I have tested this, and found that if I simply include only
the desired CBT, it works beautifully. I don't get the French, and
I do get all of the appropriate text for my indicated English
condition.

topic.
That's what Adobe tried to tell me to do. I explained to them
the issue with the same URL being used in all of my conditional
outputs.
For instance, I want Help to come up and display the exact
topic whose name in English is "View." This topic has been assigned
a Map ID of 388. I have also edited the Topic ID to use the number
388. When I generate WebHelp output, you see this topic generated
as "388.htm."
Now, in my French output, this topic would have a different
title appearing--in French, it would be called "Afficher." My
programmers have our application programmed to call "388.htm,"
regardless of what language is running.
RH source topics cannot use the same topic ID on more than
one topic. Because of this RH limitation, I must put the source
text for both languages inside only one source topic: the topic
whose Topic ID is 388.

Title.
I told the Adobe employee who called me that they need to
code RH so it looks for the Topic Heading material for the text
they use to populate their Search Results list. He sounded
intrigued by my idea, and said he would tell their engineers about
it.
The only other alternative I can imagine at this point is to
allow CBTs to be applied to the Topic Title text. I have even
attempted to manually apply this in the HTML Editor pane. The
trouble is, when I switch away to the Design Editor pane and then
back to the HTML Editor pane, all of the CBTs that I manually
applied have been lost--and it doesn't matter if I Saved first!
They are simply discarded by RH.

This is exactly the sort of programming issue they earn the
big bucks to solve--establishing workarounds for the technologies
at work.
I have to believe it's solvable, because, as I have told the
Adobe folks, their competitor MadCap had the exact same issue with
one of their early versions, and they even told me: "The Search
Results list is being populated before the conditions are being
applied." I called them on it, they worked to solve it, and they
ultimately did solve it in Flare by reworking one of their *.DLL
files.
Maybe I'm comparing apples to oranges, but I still have faith
that this can be solved. My only problem is how long it is taking
to get this issue onto their radar. I have been requesting this
functionality for over 1.5 years!

Maybe some folks who work in multiple languages could chip in
and advise how they work.
I am guessing that where Map IDs are used for the call, they
maintain two projects so that the "same" topic can have the same
ID.
I already do this in RH X5. I maintain five separate
projects, which contain about a dozen different conditions.
However, I have never yet used CBT functionality on the text
in my 5 projects, because my source remains in Word to this day,
and only RH HTML even comes close to giving me the conditional
output I require. In today's Help files, our users must read and
find the text that applies to their condition, because they are
often presented with text like so:
Condition A
* If you are Condition A, then the software does this...
Condition B
* If you are Condition B, then the software does this...
Condition C
* If you are Condition C, then the software does this...
Condition D
* If you are Condition D, then the software does this...
Condition E
* If you are Condition E, then the software does this...
I was actually asked to split out our conditions in this
manner by managers at my company.
Now, if I were a user, I would HATE having to read
documentation like this.
We actually split out our conditions in this way in 2002!,
anticipating that eHelp or (later) Macromedia or (now) Adobe would
provide the CBT functionality so I could hide all of the other
conditions, and give my users a Help file customized specifically
for their business line. It's now 6 years and counting...
Since I will have some major prep work to do in order to
import my text with minimum pain into RH 7 HTML, I just won't do it
until or unless I can prove that I will be able to output all of my
conditions flawlessly. It doesn't pay my company to do the import
and cleanup if we can't produce the product we are required to give
our users.

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:
<html>

this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

A puzzling situation...help needed urgently!

This is somewhat related to the topic I posted here (the app is the same) : http://forum.java.sun.com/thread.jspa?threadID=5253292
So I managed to set things straight and pass the value of the floor selected from the drop down list to a page called FloorPlanRender.jsp (the parameter name is "floorselected", and I store this parameter into an integer variable of the same name as shown in the code for the whole page below). A controller class receives the request, initializes the DB connection and redirects to the appropriate JSP page (not shown in the codes below, but it works fine) -
[BTW, I have posted the entire code for the page and classes involved...that was just to make the code more informative. The problem seems to be in a very small part of the code alone].

                    Now, using this value for floor selected, I have to get the rows and columns configured for this floor from a database. This involves performing a select max statement so that I can get the maximum row and column number respectively.

        System.out.println("Could not get floor numbers: " + e.getMessage());
      finally {
        dataManager.putConnection(connection);
    return floorplanrenderelements;
}When I run the application and choose my floor, the result throws me a "No floor plan exists...." [the else...part in the jsp page].
I have come to know that it is because for some odd reason, the rowcount and columncount variables are not being set properly. I have tested the queries used in the FloorPlanRender peer class in the mySQL query browser and they work (both the row and column count for floor 3 for example, should return 20). But they don't. When I printed out the rowcount and columncount variables, they were set to a 0. I thought the floorselected parameter wasn't retrieved from the previous page properly, but to my surprise it was successfully set to 3, indicating the desired floor number.
I can't begin to see where the error is. There is nothing wrong with the DB connection or the query, but the correct value is not being set to the variables in the jsp page.
Can someone please have a look at the code and guide me as to what possibly is going wrong? I have spent a lot of time and effort and still haven't spotted the mistake, if any. Your help is much appreciated.

Again wrong usage of Iterator :)

</html>For god sake please bother to understand how any implementation of java.util.Iterator works
for more info go through javadocs
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Iterator.html
and i believe you have completey ignored my other suggestion of using enhanced loop in J2SE 5.0+ if iterator is confusing.
Anyways,hope the above might help you in fixing of what you are trying to..
REGARDS,
