A Downcasting example. Help needed
Hello,
Can someone please explain the term Downcasting?
From what I have understood is that in Downcasting,
the superclass is typecasted to a subclass.
Am I right in my understanding? or have I overlooked something?
For example:
class Animal{
class Cat extends Animal{
class Downcasting{
public static void main(String args[]){
Animal a = new Cat();
typeCasting(a);
static void typeCasting(Animal a){
Cat c = (Cat)a;
}
Yep. That's downcasting.

Internationalised Example Help Needed
My goal here is to put together an easily understandable example of an Internationalised stand-alone java application.
To start, I would like to create a stand-alone java application that performs the following tasks:
1. Has a pulldown that allows a user to select a language (English, Arabic, Korean, Greek, etc.) When the language is selected, I want to change the properties of a JTextFild so that when a user types in the JTextField, the characters that come out in the JTextField are in the language that was selected in the pulldown. I know how to create the pulldown, but how do I change the properties of the TextField dynamically?
2. I have a JButton that, when pressed, stores the language selected AND the characters in the JTextField into a Sybase Database. It also adds the same info to a JList that displays a list of text strings (in the language that they were entered) with their selected language (in English). My questions here are:
- How should I store the text in the database (Hex or Unicode?)
- Is it possible to have a JList display different languages on different lines within the list?
- Is there a generic font that can display ALL types of languages?
Any help (especially code samples) would be greatly appreciated. I have read the tutorials on this site, but I didn't see anything that would help.What do you mean when you say "the characters that come out in the JTextField are in the language that was selected in the pulldown"? The characters that are displayed in the field depend on the characters that the user inputs. There are no properties to change.
2. I have a JButton that, when pressed, stores the
language selected AND the characters in the
JTextField into a Sybase Database. It also adds the
same info to a JList that displays a list of text
strings (in the language that they were entered) with
their selected language (in English). My questions
here are:
- How should I store the text in the database (Hex
Hex or Unicode?)I don't know Sybase, so there may be implementation-specific issues, but for the DBs that I know, it would only make sense to configure the DB to store eveything in Unicode. If you store hex values, the DB will not be able to perform locale-dependent collation, etc.
>
- Is it possible to have a JList display different
ent languages on different lines within the list?
Yes, why not? As long as everything is in Unicode, you can display anything you want anywhere you want (single characters alternating, for that matter)
- Is there a generic font that can display ALL
ALL types of languages?Well, there are Unicode fonts that support MOST languages, but I think there will always be edge cases with new character sets that have only recently been added to the Unicode standard.
Any help (especially code samples) would be greatly
appreciated. I have read the tutorials on this site,
but I didn't see anything that would help.In that case I recommend that you find some of the books on Java internationalization and study them. A simple Google search will also give you some helpful links. -
Problem with Multi File upload example, help needed
I got the code from the following location.....
http://www.adobe.com/devnet/coldfusion/articles/multifile_upload.html
And I've got it to work to some degree except I cant get the file transfer to work when pressing, Upload. Below is what my debugger outputs. Any thoughts on how to fix this or even what it means?
At the very bottom of this message is the upload.cfm code.......

Flex Multi-File Upload Server Side File Handler
This file is where the upload action from the Flex Multi-File Upload UI points.
This is the handler the server side half of the upload process.
--->
<cftry>
<!---
Because flash uploads all files with a binary mime type ("application/ocet-stream") we cannot set cffile to accept specfic mime types.
The workaround is to check the file type after it arrives on the server and if it is non desireable delete it.
--->
<cffile action="upload"
filefield="filedata"
destination="#ExpandPath('\')#MultiFileUpload\uploadedfiles\"
nameconflict="makeunique"
accept="application/octet-stream"/>
<!--- Begin checking the file extension of uploaded files --->
<cfset acceptedFileExtensions = "jpg,jpeg,gif,png,pdf,flv,txt,doc,rtf"/>
<cfset filecheck = listFindNoCase(acceptedFileExtensions,File.ServerFileExt)/>
<!---
If the variable filecheck equals false delete the uploaded file immediatley as it does not match the desired file types
--->
<cfif filecheck eq false>
<cffile action="delete" file="#ExpandPath('\')#MultiFileUpload\uploadedfiles\#File.ServerFile#"/>
</cfif>
<!---
Should any error occur output a pdf with all the details.
It is difficult to debug an error from this file because no debug information is
diplayed on page as its called from within the Flash UI. If your files are not uploading check
to see if an errordebug.pdf has been generated.
--->
<cfcatch type="any">
<cfdocument format="PDF" overwrite="yes" filename="errordebug.pdf">
<cfdump var="#cfcatch#"/>
</cfdocument>
</cfcatch>
</cftry>Just 2 things in my test:
1) I use no accept attribute. Coldfusion is then free to upload any extenstion.
Restricting the type to application/octet-stream may generate errors. Also, it is unnecessary, because we perform a type check anyway.
2) I have used #ExpandPath('.')#\ in place of #ExpandPath('\')#

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIEIn short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Help needed to run JSTL 1.1 in Tomcat 6.0.16
Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below

what is the problem with my code?
When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:
{code{color:#000000}}{color}<Context path="/DBTest" docBase="DBTest" debug="5" reloadable="true" crossContext="true">

{color:#0000ff}url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>{color}
{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

EDI IDOC generation for interface with Vendor software help needed.
EDI IDOC help needed.
We are NOT an EDI shop, but have a project to output data to Sales Force.com
Sales Force requests IDOC output - eg. 810 Outbound Invoice.
We will need to do a historical load of Orders/Quotes/Invoices from the past 2 years.
Is there a function module or series of FM's that are used to generate the E2EDKxxxxx type segments?
I have been testing using the IDOC_OUTPUT_INVOIC and IDOC_OUTPUT_ORDRSP FM's, but they generate segments begining with E1EDKxxxxx.
Basicall we have a report program that the user enteres in the date range of Order/Quotes/Invoices they wish to extract, the the program needs to output a flat file (.txt) on the server which is then picked up by Sales Force.com.
Also, is there a way to have in the Partner Profile a generic Partner under the "Type KU" that can be used for all orders/invoices so I don't have to create a KU Partner Type for each and every Sold-To customer we have?
I am very new to EDI so any help would be greatly appreciated.
Thanks.
Scott.Hi Scott,
We will need to do a historical load of Orders/Quotes/Invoices from the past 2 years.
I know it's very tempting to use an interface for such loads if you anyhow have to create one. However, often the volume alone speaks against interface usage for such scenarios.
Is there a function module or series of FM's that are used to generate the E2EDKxxxxx type segments? I have been testing using the IDOC_OUTPUT_INVOIC and IDOC_OUTPUT_ORDRSP FM's, but they generate segments begining with E1EDKxxxxx.
Well, the E2* segments basically reflect the external name of the IDoc segment, whereas the function modules you're referring to basically just create an internal version of the IDoc. Once the IDoc framework then passes the IDocs to the partner, the segment names usually (depends on how the IDocs are passed on) get converted to their external name. If there are multiple versions of a segment, then the version number will be appended to the segment name.
Note that IDoc segment definitions are only partially stored in the data dictionary. If you want to see all versions you should always use transaction WE31 to look at segments. There you can also see for example for E1EDK01 the several versions and when you then use in SE37 function module SEGMENT_EXTERNAL_NAME_GET you will see what SAP produces as the external name for segment E1EDK01. This function module is basically the one that handles the segment name translations.
Ignore the comments for subsystem, this is basically an option in SAP to possibly trigger further external tools (e.g. mapping etc.) for handling the outbound IDocs.
Again, the funny thing is that via the WE30 transaction, if i put in INVOIC02 as the Obj. name and see the segments, i can see that E2EDK01 there is a version 005, but if i go to SE11 and put in E2EDK01005 structure line and i get a "not found". We just have up to E2EDK01002.
In the old days SAP used to generate E1, E2 and E3* structures in the data dictionary (SE11). The E1* structure reflected the character type representation of an IDoc segment, whereas the other two (definition and documentation) contained actual references to data elements (e.g. if you used a quantity field). However, in newer releases those dictionary structures (E2* & E3*) are no longer generated, because they're superfluous (meta data defined via WE31 is sufficient).

Help Needed in Creating Java Class and Java Stored Procedures
Hi,
Can anyone tell how can i create Java Class, Java Source and Java Resource in Oracle Database.
I have seen the Documents. But i couldn't able to understand it correctly.
I will be helpful when i get some Examples for creating a Java Class, Java Source and Stored Procedures with Java with details.
Is that possible to Create a Java class in the oracle Database itself ?.
Where are the files located for the existing Java Class ?..
Help Needed Please.
Thanks,
Murali.vHi Murali,
Heres a thread which discussed uploading java source file instead of runnable code on to the database, which might be helpful :
Configure deployment to a database to upload the java file instead of class
The files for the java class you created in JDev project is located in the myworks folder in jdev, eg, <jdev_home>\jdev\mywork\Application1\Project1\src\project1
Hope this helps,

Unfortunately this is very difficult because the top half of your post, your really the only one that can answer what the setup should be. The adjustments are made based on the acoustics of your room and how everything sounds noone can really give you info on it because every house, and room has different acoustics. The walls, insulation, carpet or bare floors, basement or main floor are just some examples of what can make a difference in sound reproduction. By the way NHT (Now Hear This) are excellent speakers. For bass and treble, the music I listen too requires a high treble content so I usually have it at 7 out of 10 but my bass is at 4 out of 10. The sub base should be fine where it is.
Did your receiver come with an Audessy mic for calibration. I would use that for a basic setup and go from there I am not sure if on your unit it will do frequecy but I think it did.
Your volume settings look fine again personal preference there is right or wrong.
For you listening mode Preset you should have an auto setting I am at work so it may take a coule of hours for me to get back to you as I have to go through your manual and see what you would set it up with so please bare with me. I will list the info as I read it so it may not be in the order you have it.
I will have to make a second post since I can't go back and edit this one. -
Please help-- need to populate a jtable at runtime
Hello all,
i have this problem:
i have to populate a jtable at runtime.i take the data
from different buttons and from a jlist.i will focus
on the jlist here because the problem is elsewhere
after i select the particular items from the list i put them in a 2d array. the problem is that this array
might have null entries.for example, according to the
list item selections, my array might look like this:
data[0][0] = "somedata"
data[0][1] = ""
data[0][2] = "otherdata"
and so on
when i try to add row to the table it adds the
data[0][1] as well (tablemodel.addRow(data[0]);)
is there any way to make it not print the elements
that have null values?
the problem is that the number of rows and the number of columns of data is generated at runtime and it can be up to data[6][200] so if i only put data in say
data[45] and data[i][195] i only want to print
this values in the jtable's rows and not the whole
data[i]
i try to put the results of data[][] that are not null in a new array but it doesnt work.here is how i try to do this:
for (int i=0;i<data[0].length;i++) {
for (int b=0;b<data.length;b++) {
while (data[b][i] != null)
datanew=data;
when i try to add row datanew[b] in the jtable i see the same result (some columns are empty)
if i try to print data[b] i see something like "Ljava.jang.string:2@#435"
but if i print data[b][i] for the i's that are not null then i see the right results.
is there any way i can do it ?maybe exceptions handling? i dont know.
any kind of help would be greatly appreciated.
i am a begginer in java, i hope i dont sound ridiculous.
thank you in advancethanks for your reply everybody
well i have changed the algorithm a little and now it works. however, i have a similar problem right now
as i said in the beggining the data will be selected both from a jlist and some buttons. now the list work.
the list has items that relate to buttons.
so now i have one more condition that will show only the
results of the list that relate to the buttons.
i have done this by using a boolean when each button is
selected.
the problem now is that i have an array that have null rows (instead of null columns that i had before)!!
even though i can add them to the jtable normally since
they are rows, i dont want to show empty rows.
so i want to create a new array that will have as rows
all the rows of the first array that contain data.
Here is my algorithm that generates data according to jlist and buttons selection:
Object[] selected_items = charList.getSelectedValues();
for (int j=0;j<selected_items.length;j++)
tablemodel.addColumn(selected_items[j]);
for (int k=1;k<data[0].length;k++){
if ( selected_items[j].equals(data[0][k]) ){
for (int b=0;b<=data.length-2;b++){
if (authors_boolean_array)
data3[b][j]=data[b+1][k];
else System.out.print("no author ");
else System.out.print("no ");
System.out.println("");
doesnt matter how it works. the result is that it ends
with a data3[b][j] array that can be up to data3[6][200]
and might have empty rows
so i want a new array say data4[][]
for example i need to find a way to do something like this:
data4[0][0] = data3[0][0];
data4[0][1] = data3[0][1];
data4[1][0] = data3[2][0];
data4[1][1] = data3[2][1];
i tried something like this: (count is the number of the selected buttons)
for (int j=0;j<selected_items.length;j++){
for (int b=0;b<=data.length-2;b++) {
if (data3[b][j] != null) {
for (int c=0;c<count;c++) {
for (int d=0;d<selected_items.length;d++) {
data4[c][d]=data3[b][d]; // (*)
else System.out.println("data4 null");
but it doesnt work because b isnt increased as need
at (*) line
well i know this is causing a hedaque so i wont be suprised if i dont receive any answer.however, since there are always some kind people arround i thought i could give it a try as it would save me precious time.
thank you all for your time -
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 with Report Design
Hi All,
Here is the requirement.
Period Type(holds 2 values) : Payment and Vested.
we have field 'Total Days' which is calculated based on "User Selected" Period Type.
For example, When Period Type is Payment,
If start date is less than or equal to grant date and end date is less than or equal to vest date, then calculation is (End Date - Grant Date)+1
If start date is greater than grant date and end date is less than or equal to vest date, then calculation is (End Date - Mobility Start Date)+1 (similarly 2 more if conditions) ...we have similar calculation for Period Type - 'Vested'.
This Period Type is a multiselect Prompt. How can this be achievable.
Any thoughts will be greatly appreciated.

About Java 2 opaque font color question, help needed!
About Java 2 opaque font color question, help needed!
I was trying to test opaque font (the string has a foreground color and a background color), but i can't find the method for doing that.
i can change foreground by Graphics2D.setPaint(Color.black).
Anybody know how to change the background of the string?
Thanks!Hi. The way I'd do it would be to use the font metrics to find the length of a string and draw a rectangle and then drawstring over the rectangle. If you want an example, I can post it although I suspect theres a better way.

New Nokia E7 just bought in Italy * help needed to...
I just bought a new E7
Very nice and light but I let my old E90 and I need some help to solve some problems
How can I
*If I want to check mail manually there is nowhere a function or option or button "check mail" !!
*In my address book of E90 I could add some details on the descriptions. I can't there ! If for an example I wanted to make difference etween more mobiles number on a name I could put on E90 mobile perso or mobile night or mobile urgency
There I can't add any detail on the voices on the phone !
And when I transferred from E90 all those details are now lost and I have the name with 5 mobiles numbers without any tag or note !
*Other very big problem, when you send mails (not sms) there is no folder "sent mails" anywhere !!! You can't keep you sent mails !!!
in italian
* Nei vari indirizzi mail come faccio a fare il controllo mail manualmente ? Non esiste nelle opzioni o da nessuna parte il tasto check mail o similare
* Nella rubrica a differenza sempre del mio ultimo E90 se voglio mettere un dettaglio su le varie voci non posso. Per esempio Mario Rossi ha tre numeri cellulari dove prima mettevo numero celliulare giorno, numero urgenze o numero riservato e adesso non posso. Oltre ad avermi nel trasferimento dei dati dall e90 a e7 perso tutti i "dettagli" della rubrica qui sopra spiegati. Mi ha trasferito i numeri ma senza i dettagli che avevo aggiunto
* Importante per le mails quando invio una email NON appare da nessuna parte una cartella o folder SENT MAILS. Assurdo ma non c e una cartella mails inviate ! appare sms inviati ma da NESSUNA parte mails inviate !!!no news from Nokia...

Offscreen drawing and Events help needed!!
Hi,
I have run into a problem... I need to create a rather complicated image with lots of interactivity. As a simplified example, I need to add a grid, a histogram, and a pie chart on the same JPanel.
Normally, you create your images in your class, set up listeners on your graphics objects and voila, clickable images.
But I want to create all my images in a separate class, attach listeners there and then add that image and its listeners to my JPanel. Otherwise my class gets huge and painful- some of these objects (the histogram for example) need to establish URL connections, execute JDBC querys, be threaded, etc. According to what I know about OOP, these should certainly be in their own class.
So, if I wanted to draw a 10x10 grid, I could simply do:
DrawGrid grid = new DrawGrid( 10, 10 ); In DrawGrid, I would have listeners on each cell, so I can keep track of what was clicked.
Adding grid to my JPanel also adds the listeners associated with grid...
I initially tried this as a separate JPanel, and then to just add the new JPanel to the 'central' one, but this wont work because some of my graphics must overlap each other- and I couldnt get graphics to overlay multiple JPanels.
I also created my graphic by extending BufferedImage and then doing:
g2d.drawImage( buffer1, 0, 0, this);
g2d.drawImage( buffer2, 0, 0, this);
Which worked for the images- but none of the listeners worked. :(
I really need some help on this one.
Also what are the best books for Java 2D graphics and interacting with them??? I gotta buy one.
Thanks!
BryanFrom what I understand, you want to have multiple images on one surface and have them all contain their own mouse listeners. As far as i know this is impossible (but what do i know:)
What you could do is have a single mouse listener and subdivide the surface whenever images are placed there. So when the user clicks it checks to see in which section was clicked, then forwards that info to the appropriate object. And to deal with overlapping just have the top image have control over that area. If you needed to get more complex wich your bounderies you could have an array of pixels representing the surface and flag them bassed on the objects in that area.
It may get a bit slow if your boundaries are too complex
