Hi,
I did a project on jsp and EJB called Dataminig implemented in Online shopping. Dataminig is an upcomming technology for Customer Relationship management. You can also do some kinda project like online patient monitering. In this project you can even see how to communicate through COM port.

Help needed for changing Project Facets
Hi,
I am facing a problem in publishing a dynamic web project on workshop for weblogic 9.2. i have set the java compiler settings to 1.3. the error displayed is "Java compiler level does not match the version of the installed Java project facet. at ...<web project name goes here>"
I checked the project facet settings as Java 5.0. this however is not editable. Is building an Ant script the way forward and if it is, what is the tag specific to project facet settings?
Thanks in advance.You can also use a LSMW.
You are lucky, this is exactly the eg taken in SAP help :

Dear members
I am looking for a developer who can help me (rebuild) and
administrative back-end based on an existing MS SQL database in
either PHP or ASP classic.
I am pretty much a novice, more a designer than a programmer
but know my way around DW and some ASP code, I am new to PHP. I do
have experience with building databases, not much however with
building databases for e-commerce purposes.
I purchased WebAssist E-Commerce Suite if someone knows what
it is and work with DW MX 2004 on a Windows XP Professional SP2 m
achine.
I am not asking for free help but help me get the job done.
There is a time frame and the money I can spent on help is not
unlimited.
Pref. someone in Europe who I can keep in contact with via
MSN Messenger and/or Skype.
I can build myself the insert, update and delete pages on
various tables.
However certain things are unclear to me wether they are
absolutely a nescessity or can be done without.
Please if you have the time and not looking for a fast buck..
contact me.
Yours sincerely

Help needed for HSC project, urgent.
Hi,
I am having further troubles. In my storybook on the first page all the buttons are appearing, I do not want this. How do I code to fix that, the only button I want on the first page is "page1_btn"
will paste my coding into here, and could you please tell me what to do to fix this ?
page2_btn.visible= false;
p3_first_btn.visible= false;
page1_btn.addEventListener(MouseEvent.CLICK,turnpage2);
function turnpage2 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page2");
page1_btn.visible = false;
page2_btn.visible= true;
page2_btn.addEventListener(MouseEvent.CLICK,turnpage3);
function turnpage3 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3");
page2_btn.visible= false;
p3_first_btn.visible= true;
p3_first_btn.addEventListener(MouseEvent.CLICK,turnpage3a);
function turnpage3a (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3a");
p3_first_btn.visible= false;
And, also the reason why I am setting the buttons to visible= true; at the start and visible= false; at the end is because I can only have one button for each page.
Please help someone,
Regards,
AdamIn your code you are:
1. setting page2_btn and p3_first_btn to visible false, then you set an event listener and function for page1_btn.
2. setting page2_btn to be visible true and setting an event listener and function for that button.
3. setting p2_first_btn to be visible true and setting an event listener and function for that button.
If all of this code is in the same frame, then you are turning all of the buttons' visible properties to true.
If you only want one of those buttons to be visible at any one time then set the visible property for page2_btn to true at the end of the function turnpage2 and do the same for p2_first_btn.
Something like this:
page2_btn.visible= false;
p3_first_btn.visible= false;
page1_btn.addEventListener(MouseEvent.CLICK,turnpage2);
function turnpage2 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page2");
page1_btn.visible = false;
page2_btn.visible= true;
page2_btn.addEventListener(MouseEvent.CLICK,turnpage3);
function turnpage3 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3");
page2_btn.visible= false;
p3_first_btn.visible= true;
p3_first_btn.addEventListener(MouseEvent.CLICK,turnpage3a);
function turnpage3a (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3a");
p3_first_btn.visible= false;

Hi, everyone.
I am new in java.
I try to unstand one command in unix cron job as following:
java -Xmx256m -classpath .:./jse.jar:./commons-codec.jar com.etsi.jse.run.usa.apartments.SearchingWithCity $*
i can't figure out what "$*" stands for.
If any suggestions, thanks a lot> i can't figure out what "$*" stands for.
It's a command line argument that gets used to initialize the String[] array passed to the main method. My guess is that it's a regular expression-ish search string with a "wildcard" used by the program to find apartments within particular city, judging by the name of the package and class.

Help needed for java network programming
How can I implement a GUI as a client in my server-client program.
I have a window(JFrame)having one Textfield and a "Send" button.
My requirement: While execution, the GUI should start as a client, and whatever textinput I will give to the Textfield, that should be printed in the server program.
So, how can I implement a GUI window as a client.
If any of U have idea,Please let me know soon.
Regards.Well, the client part and the GUI part are separate. The button simply calls a send method.
As for the networking, you can just use a Socket and a ServerSocket on the client and server, respectively. Then, wrap a PrintStream around one side and a BufferedReader(InputStreamReader()) around the other. You'll be able to talk back and forth once your connection is established; it's up to you to read from the BufferedReader and use the results on the server side. -

Hello everyone
I'm a Student and new to java and I have been given a question which I have to go through. I have come across a problem with one of the questions and am stuck, so I was wondering if you guys could help me out.
here is my code so far:
A Class that maintains Information about a book
This might form part of a larger application such
as a library system, for example.
@author (your name)
*@version (a version number or a date)*
public class Book
// instance variables or fields
private String author;
private String title;
Set the author and title when the book object is constructed
public Book(String bookAuthor, String bookTitle)
author = bookAuthor;
title = bookTitle;
Return The name of the author.
public String getAuthor()
return author;
Return The name of the title.
public String getTitle()
return title;
and below are the questions that I need to complete. they just want me to add codes to my current one, but the problem is I don't know where to put them and how I should word them, if that makes sense.
Add a further instance variable/field pages to the Book class to store the number of pages in the book.
This should be of type int and should be set to 0 in the Constructor.
Add a second Constructor with signature
public Book(String bookAuthor, String bookTitle, int noPages) so it has a third parameter passed to it as well as the author and title;
this parameter is used - obviously?? - to initialise the number of pages.
Note: This is easiest done by making a copy of the existing Constructor and adding the parameter.
Add a getPages() accessor method that returns the number of pages in the book.
Add a method printDetails() to your Book class. This should print out the Author title and number of pages to the Terminal Window. It is your choice as to how the data is formatted, perhaps all on one line, perhaps on three, and with or without explanatory text. For instance you could print out in the format:
Title: Robinson Crusoe, Author: Daniel Defoe, Pages:226
Add a further instance variable/field refNumber() to your Book class. This stores the Library's reference number. It should be of type String and be initialised to the empty String "" in the constructor, as its initial value is not passed in as a parameter. Instead a public mutator method with the signature:
public void setRefNumber(String ref) should be created. The body of this method should assign the value of the method parameter ref to the refNumber.
Add a corresponding getRefNumber() accessor method to your class so you can check that the mutator works correctly
Modify your printDetails() method to include printing the reference number of the book.
However the method should print the reference number only if it has been set - that is the refNumber has a non-zero length.
If it has not been set, print "ZZZ" instead.
Hint Use a conditional statement whose test calls the length() method of the refNumber String and gives a result like:
Title: Jane Eyre, Author: Charlotte Bronte, Pages:226, RefNo: CB479 or, if the reference number is not set:
Title: Robinson Crusoe, Author: Daniel Defoe, Pages:347, RefNo: ZZZ
Modify your setRefNumber() method so that it sets the refNumber field only if the parameter is a string of at least three characters. If it is less than three, then print an error message (which must contain the word error) and leave the field unchanged
Add a further integer variable/field borrowed to the Book class, to keep a count of the number of times a book has been borrowed. It should (obviously??) be set to 0 in the constructor.
Add a mutator method borrow() to the class. This should increment (add 1 to) the value of borrowed each time it is called.
Include an accessor method getBorrowed() that returns the value of borrowed
Modify Print Details so that it includes the value of the borrowed field along with some explanatory text
PS. sorry it looks so messey1. In the future, please use a more meaningful subject. "Help needed with java" contains no information. The very fact that you're posting here tells us you need help with Java. The point of the subject is to give the forum an idea of what kind of problem you're having, so that individuals can decide if they're interested and qualified to help.
2. You need to ask a specific question. If you have no idea where to start, then start here: [http://home.earthlink.net/~patricia_shanahan/beginner.html]
3. When you post code, use code tags. Copy the code from the original source in your editor (NOT from an earlier post here, where it will already have lost all formatting), paste it in here, highlight it, and click the CODE button. -
help needed for writing query
i have the following tables(with data) as mentioned below
FK*-foregin key (SUBJECTS)
FK**-foregin key (COMBINATION)
1)SUBJECTS(table name)
SUB_ID(NUMBER) SUB_CODE(VARCHAR2) SUB_NAME (VARCHAR2)
2 02 Computer Science
3 03 Physics
4 04 Chemistry
5 05 Mathematics
7 07 Commerce
8 08 Computer Applications
9 09 Biology
2)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2) SUB_ID1(NUMBER(FK*)) SUB_ID2(NUMBER(FK*)) SUB_ID3(NUMBER(FK*)) SUBJ_ID4(NUMBER(FK*))
383 S1 9 4 2 3
384 S2 4 2 5 3
---------I actually designed the ABOVE table also like this
3) a)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2)
383 S1
384 S2
b)COMBINATION_DET
COMBDET_ID(NUMBER) COMB_ID(FK**) SUB_ID(FK*)
1 383 9
2 383 4
3 383 2
4 383 3
5 384 4
6 384 2
7 384 5
8 384 3
Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2 SUBJECT3 SUBJECT4
383 S1 Biology Chemistry Computer Science Physics
384 S2 Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID subjects
383 Biology,Chemistry,Computer Science,Physics
384 Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --PradeeshWell I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say. -
Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with re
Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with reddish cast and loss of detail
System: Windows 7
Adobe CS5
Printer: Epson Stylus Photo 1400
Paper: Inkjet matte presentation paper with slight luster
Installed latest patch for Adobe CS5
Epson driver up to date
After reading solutions online and trying them for my settings for 2 days I am still unable to print what I am seeing on my screen in Adobe CS5. I calibrated my monitor, but am not sure once calibration is saved if I somehow use this setting in Photoshop’s color management.
The files I am printing are photographs of dogs with lots of detail I digitally painted with my Wacom tablet in Photoshop CS5 and then printed with Epson Stylus 1400 on inkjet paper 20lb with slight luster.
My Printed images lose a lot of the detail & come out way to dark with a reddish cast and loss of detail when I used these settings in the printing window:
Color Handling: Photoshop manages color, Color management -ICM, OFF no color adjustment.
When I change to these settings in printer window: Color Handling: Printer manages color. Color management- Color Controls, 1.8 Gamma and choose Epson Standard it prints lighter, but with reddish cast and very little detail and this is the best setting I have used so far.
Based on what I have read on line, I think the issue is mainly to do with what controls are set in the Photoshop Color Settings window and the Epson Printer preferences. I have screen images attached of these windows and would appreciate knowing what you recommend I enter for each choice.
Also I am confused as to what ICM color management system to use with this printer and CS5:
What is the best ICM to use with PS CS5 & the Epson 1400 printer? Should I use the same ICM for both?
Do I embed the ICM I choose into the new files I create?
Do I view all files in the CS5 workspace in this default ICM?
Do I set my monitor setting to the same ICM?
If new file opens in CS5 workspace and it has a different embedded profile than my workspace, do I convert it?
Do I set my printer, Monitor and PS CS5 color settings to the same ICM?
Is using the same ICM for all devices what is called a consistent workflow?
I appreciate any and all advice that can be sent my way on this complicated issue. Thank you in advance for your time and kind help.It may be possible to figure out by watching a Dr.Brown video on the subject of color printing. Adobe tv
I hope this may help............... -

This is the Question
Create a class ToyCollection that stores information about different toys in a toy shop. The information to be stored about a single toy is,
- Toy identification as String
- Name of the toy as String
- Short description about the toy as a String
- Price of the toy as float
- Quantity of the toy in hand as short integer.
This class contains following methods,
- Constructor method that assigns user input values to above mentioned variables.
- main ( ) method that creates array of 4 objects of ToyCollection class and that takes input for all above details from the user and
calls method to check validity of Quantity and Price values. If all values are valid then create the objects and display the details
for all 4 toys.
- Method that checks validity of quantity and price. If the quantity is 0 or negative then method should throw user defined
exception with appropriate message and come out of program. Similarly if the price is 0 or negative then it should throw user defined exception with appropriate message and come out of program.
- Method that displays all details about a single toy in the following format, e.g. Here Total price should be calculated.
Toy Identification : S-1
Toy Name : Small Scooter
Toy Description : Ordinary 3 wheeler scooter
