Need help in ADF Programming

Hi Team,
I am using Jdev 11.1.2.3.0
I have some doubts in ADF programming. Please explain with clear steps
1) How to access VORowImpl method or EORowImpl method from AM and AM method from VO or EO.
2) How to access AM instance from some other AMImpl
Thanks in advance,
Rakesh

1) Assuming you have the ViewObject (which is an interface of all public available methods of a view object) you get the ViewObjectImpl class by casting the VO like
ViewObject vo = am.findViewObject("EmployeesView);
EmployeesViewImpl voImpl = (EmployeesViewImpl) vo;
//get VOrowImpl
Row row = vo.next();
EmployeeRowImpl = (EmployeeRowImpl ) row;
Got get a ClassCastException if the row interface does not point to the class you try to cast to!
2) This depends if the application module knows the other AM (e.g. amChild is a child of amMaster). In this case you can use amMaster.findApplicationModule("NAME_OF_CHILD");
If the AM is not known you have to service enable the AM and use the service interface (Integrating Service-Enabled Application Modules)

Need help writing host program using LabView.

Need help writing host program using LabView.
Hello,
I'm designing a HID device, and I want to write a host program using National Instrument's LabView. NI doesn't have any software support for USB, so I'm trying to write a few C dll files and link them to Call Library Functions. NI has some documentation on how to do this, but it's not exactly easy reading.
I've written a few C console programs (running Win 2K) using the PC host software example for a HID device from John Hyde's book "USB by design", and they run ok. From Hyde's example program, I've written a few functions that use a few API functions each. This makes the main program more streamlined. The functions are; GetHIDPath, OpenHID, GetHIDInfo, Writ
eHID, ReadHIC, and CloseHID. As I mentioned, my main program runs well with these functions.
My strategy is to make dll files from these functions and load them into LabView Call Library Functions. However, I'm having a number of subtle problems in trying to do this. The big problem I'm having now are build errors when I try to build to a dll.
I'm writing this post for a few reasons. First, I'm wondering if there are any LabView programmers who have already written USB HID host programs, and if they could give me some advice. Or, I would be grateful if a LabView or Visual C programmer could help me work out the programming problems that I'm having with my current program. If I get this LabView program working I would be happy to share it. I'm also wondering if there might already be any USB IHD LabView that I could download.
Any help would be appreciated.

if anyone could please tell me whats wrong with my code i'd be greatful...the program is supposed to perform binary and sequential search on a sorted array of 100000 numbers.once on an item in the middle of the array once on the right side of it and once on the left side...i also need to count the number of basic operations for the same number in both sequential and binary to see whats better.and i need to check the time...i think the method call is wrong,not sure though...plz i need help.its not compiling and i dont know why..

Just add new messages to a thread you've already created. Don't create a new thread each time.
Anyway, look. This is wrong:int seqSearch(z;50000;n); //method call 4 key where key=midfor two reasons. The first is that leading "int"; it doesn't mean anything here. "int" is used to declare an integer variable, but you're not declaring a variable here, you're invoking a method. The second problem is that you're using semicolons to separate arguments in the method call, but actually commas are correct. You probably want something more like this:
int result;
result = seqSearch(z, 50000, n); //method call 4 key where key=mid.
Some more problems with your code: you're calling non-static methods in a static context (the main method is static and seqSearch isn't). You're also using "n" before you declare it, which is probably a problem.
And this makes no sense:z=2*i;because you've declared z to be an array; you can't use the multiplication operator on an array. It's not clear really what you're trying to accomplish there.
Here's what I want you to do. Take your code and completely remove the binSearch method. Just rip it out. Then in your main() method, take out all references to the binSearch method, and all references except for the first one of the seqSearch method. Fix the things I mentioned above.
Then try to compile what you have. It won't compile. You will get error messages. That's OK. Just fix them and move on. If you don't understand an error message, ask on these forums (DON'T CROSSPOST), quoting the full error message and the relevant lines of code.
After a couple hours, you'll fix the syntactical bugs, and your program will compile. Then you'll find that it compiles but the program doesn't work right. That's also OK. This is how computer programming works. It's part of the process. Don't panic. At that point, you can start trying to fix the program so it does what it's supposed to. Eventually you'll get it to work.
Then, and only then add more invocations of the seqSearch method. They won't all work, probably. You'll find more bugs. That's OK. Just repeat the process of fixing them.
When you've fixed those bugs, then, and only then, add the binSearch method. Repeat the process of fixing syntax and hunting down and fixing bugs.
Then your program will work.

Need help with inventory program!!! someone please help me!!!

Ok I have to write this inventory program for one of my classes.
For part one i needed to Create a product class that holds the item number, the name of product, the number of units in stock, and the price of each unit.
Then create a java application that displays all of the above info plus the total value of the inventory. I have done this so far with success.
For part two i needed to modify the program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time including the item number, the name of the product, the number of units in stock, the price per unit, and the value of the inventory of that product. In addition, the output should display the value of the entire inventory.
so create a method to calculate the value of the entire inventory.(i did this)
and create another method to sort the array items by the name of the product. ( i did this)
The program compiles and runs fine except it is not doing anything from part two. It just does the same thing that it did when i wrote part one.
Does anyone know why or what i need to do to my code.
Here is my code.
import java.util.Scanner; // program uses class Scanner

You will get more help if your code is formatted better:
* Only post code that is already formatted correctly including indentations.
* Get rid of all those comments cluttering up your code.
* Make sure your posted code compiles without need for any changes. Yours doesn't at present. Where is the ProductInfo class?
Again, you want it easy for a volunteer here to read your post, otherwise he/she simply won't do it. Good luck.

Create a program called CerealCompare using an if-then-else structure that obtains the price and number of ounces in a box for two boxes of cereal. The program should then output which box costs less per ounce.

class CerealCompare {
public static void main(String[] args) {
// your code goes here
}Hope that helps.
P.S. Java does not have an if-then-else statement.

hi,
I am currently doing a project in pda application. We are using jeode as a VM for the pda. But it uses java 1.2. Maybe you want to have a look at it. however u cant use the swing class in jeode and only awt is the class availlable for programming interfaces.
If you need jeode u can contact me. I can give you a free copy which was availlable till last year as now it has gone chargable.
Also do you have any idea about how can i read and write txt files or dat files from desktop using java. I want to use a usb cradle for connection.
This information would be really appreciated as I need this for my second year project.

See struts documentation here http://struts.apache.org/1.2.9/userGuide/building_controller.html#action_mapping_example
you should have something like that :
<action-mappings>
        <action
            path="/signup"
            type="org.apache.struts.webapp.example.SignupAction"
            name="signupForm"

            input="/signup.jsp"
            unknown="false"
            validate="true" />
    </action-mappings>in your struts-config.xml.
Hope That Helps

Need help deleting a program called KompoZer

Hi guys,
I downloaded a program for WYSIWYG editor, it is called KompoZer. I dont need it but I cannot delete the dmg file from the desktop or remove the the icon from the task bar.
When I try and drop the dmg file into the trash I get the following message:
The disk "KompoZer en-US" couldn't be ejected because "KompoZer" is using it.
Quit that application and try to eject the disk again.
Although I'm not using the program, any help would be greatly appreciated!

Open Activity Monitor in the Utilities folder and see if you can see anything for KompoZer listed. If son, select it and click on the big red button at the top of the window to quit the process - then try deleting the app.
(If you are running Mavericks the red button has been replaced with an x in the top left corner).

I also need help with a programming assingment. I think I'm almost there!

I have the following assingment to complete:Once again, you realize that you need to upgrade your Java program with two more features:
Be able to print products which are �On Sale�.
Use arrays to store the product names so that you can keep track of your inventory.
After some analysis, you notice that printing the products can be achieved by modifying the two classes you have already written. One approach would be to add a Boolean attribute called �OnSale� to the ToddlerToy and add a print method that print information about a product indicating if it is �On Sale�.
Update your constructor, taking into account the �On Sale� attribute.
Create two more instances: a small train called Train4 and a big train called Train5. Mark both trains �On Sale�
Add another method that prints the sale information
Keeping track of the names of products can be achieved by declaring an array of strings in the ToysManager class itself. Each time a new product is created, it is also added to the array. Use a while construct to print the product names in your inventory.
This is the code I have come up with:
public class ToysManager {
     private String toyInventory[] = {"Big Train","Small Train"};
     public void printInventory() {
     System.out.println("List of Items in Toy Inventory");
     for (int i=0; i<toyInventory.length; i++)
     { System.out.println(toyInventory[i])); } // ";"expected - ToysManager.java
     public static void main(String[] args) {
          //System.out.println("This is the main method of class ToysManager.");
          //call on ToysManager printInventory method for a listing of all toy types
          printInventory();
          // Create ToddlerToy Objects Train1,Train2,Train3,Train4,Train5
     ToddlerToy Train1 = new ToddlerToy(489, "Big Train", 19.95,false);
     Train1.printOnSale();
     ToddlerToy Train2 = new ToddlerToy(489, "Big Train", 19.95,false);
     Train2.printOnSale();
     ToddlerToy Train3 = new ToddlerToy(477, "Small Train", 12.95,false);
     Train3.printOnSale();
     ToddlerToy Train4 = new ToddlerToy(477, "Small Train", 12.95,true);
     Train4.printOnSale();
     ToddlerToy Train5 = new ToddlerToy(489, "Big Train", 19.95,true);
     Train5.printOnSale();
}     //this is the end bracket for the main method
}          //this is the end bracket for the ToysManager class
class ToddlerToy {
     // Initialize and Assign Data Types to each Variables
     private int productID;
     public String productName;
     public double productPrice;
     private boolean onSale;
public void ToddlerToy(int a, String b, double c, boolean d) {
     // Assign Data to Variables
     productID = a;
     productName = b;
     productPrice = c;
     onSale = d;
     //PrintProductPrice(ProductPrice);
     } //end of constructor
public void printOnSale(){
     if(onSale == true) System.out.println("This item #" + productID + ": " + productName + "is on sale");
I don't have any problems with class ToddlerToy. I can compile that with no problems. I'm having issues with public class ToysManager. I can't compile that one correctly. It fails at:
{ System.out.println(toyInventory[i])); } // ";"expected - ToysManager.java
I've looked through the java books I have and also online, but I can't figure this out. I'm new to java so any help would be appreciated.
Thanks in advance.

Thanks. That got me past that error. I was hung up on that for far too long. I made some changes and when i compile the ToysManager class it shoots a different error. The code now looks like this:
public class ToysManager {
     private String toyInventory[] = {"Big Train","Small Train"};
     public void printInventory() {
     System.out.println("List of Items in Toy Inventory");
     for (int i=0; i<toyInventory.length; i++){
     System.out.println(toyInventory);
     public static void main(String[] args) {
          //System.out.println("This is the main method of class ToysManager.");
          //call on ToysManager printInventory method for a listing of all toy types
          printInventory();
          // Create ToddlerToy Objects Train1,Train2,Train3,Train4,Train5
     ToddlerToy Train1 = new ToddlerToy(489, "Big Train", 19.95,false);
     Train1.printOnSale();
     ToddlerToy Train2 = new ToddlerToy(489, "Big Train", 19.95,false);
     Train2.printOnSale();
     ToddlerToy Train3 = new ToddlerToy(477, "Small Train", 12.95,false);
     Train3.printOnSale();
     ToddlerToy Train4 = new ToddlerToy(477, "Small Train", 12.95,true);
     Train4.printOnSale();
     ToddlerToy Train5 = new ToddlerToy(489, "Big Train", 19.95,true);
     Train5.printOnSale();
     }     //this is the end bracket for the main method
}          //this is the end bracket for the ToysManager class
I get an illegal start of expression for:
     public static void main(String[] args) {
and ";" expected for:
     }     //this is the end bracket for the main method
I looked over my initial code, before the "for" loop?, and the public static void main was a valid statement.

Need help with inverter program

I am very new to labview and I need a lot of help fast. I have been given this vi program, which I have attached, that operates a bunch of inverters. The program is driving the inverter which in turn drives the agitator on a washing machine. The agitator goes in forward and reverse direction as a result of a relay within the inverter being supplied voltage to make it open and close. I need to supply voltage to the relay to make it go forward, reverse, and the pause before the next cycle begins. The current program has it doing a forward reverse and then immediately starts the next cycle. If any one can take a look at this program and let me know, first of all what the heck is going on, and second how to fix my problem, that would be incredibly helpful to me. If anyone has trouble opening the file let me know, I think attaching the vi should work but it may also look for a dll file or something when trying to open. Email me if you cannot open the file and I will send you the dll file as well. Your help is greatly appreciated. Thank you very much.

Hello Tony,
you programmed it to run continously...
After the timed while loop runs through your array of ramp values you start again at index 0 (upper shift register). Instead of this end this while loop by combining the output from the comparison with your stop2 button (end loop when stop2 OR end of arrray). Now it will work.
Btw. why do you use "Insert to Array" when you want to concat 3 arrays (sequence frame 0)? Just use a "Build Array" and set "Concat Inputs" via mouse right-click.

New to Java and need help with this program..please!

I'd really appreciate any helpful comments about this program assignment that I have to turn in a week from Friday. I'm taking a class one night a week and completely new to Java. I'd ask my professor for help, but we can't call him during the week and he never answers e-mails. He didn't tell us how to call from other classes yet, and I just can't get the darn thing to do what I want it to do!
The assignment requirements are:
1. Change a card game application that draws two cards
and the higher card wins, to a Blackjack application
2. Include a new class called Hand
3. The Hand class should record the number of draws
4. The application should prompt for a number of draws
5. The game is played against the Dealer
6. The dealer always draws a card if the dealer's hand total is <= 17
7. Prompt the player after each hand if he wants to quit
8. Display the total games won by the dealer and total and the total games wond by the player after each hand
9. Display all of the dealer's and player's cards at the
end of each hand
10. Player has the option of drawing an additional card after the first two cards
11. The Ace can have a value of 11 or 1
(Even though it's not called for in the requirements, I would like to be able to let the Ace have a value of 1 or an 11)
The following is my code with some comments about a few things that are driving me nuts:

Thank you so much for offering to help me with this Jamie! When I tried to call change value using:
Card dealer = (d.changeValue());
I get an error message saying:
Incompatible types found: int
required: Card
I had my weekly class last night and the professor cleared up a few things for me, but I've not had time to make all of the necessary changes. I did find out how toString worked, so that's one question out of the way, and he gave us a lot of information for adding another class to generate random numbers.
Again, thank you so much. I really want to learn this but I'm feeling so stupid right now. Any help you can give me about the above error message would be appreciated.

Need Help With Shell Programming

Hi, I need some guidance as to how to approach my project.
I need to develop a shell to host an e-learning environment that can be accessed through the internet. The user, preferably, needs not to download anything to run/start the e-learning environment. This e-learning environment allows users/students to create a forum, create a chatroom, hand up projects, send mail, do surveys and tutorials online and these can be submitted to the teacher/marker and receive feedback and also view their grades and schedule. Eg, Blackboard http://www.blackboard.com/
The problem is is that there seems to be no shell programming by using java. I have found only shell programming using UNIX, korn and C. I read other posts in the forums here concerning shell programming and alot of the codes include the first 2 lines :
Runtime rt = Runtime.getRuntime();
String command = "your_shell_script_command";
try {
      Process process = rt.exec(command);
     from = new BufferedReader(new InputStreamReader(process.getInputStream()));
     to = new PrintWriter(process.getOutputStream(), true);
catch (IOException e) {         ...       }the above codes were taken from this post: http://forum.java.sun.com/thread.jsp?forum=57&thread=352231
Does it means that I need to use another language besides Java to program a shell and then run it together with my java program? If so, what language do I need to learn and what Java "component" do I need to use? and is it possible to run a shell in an applet, since the applet is viewable through a browser?
I really need some help on this problem as I don't have a clue to go about it at all. Thanks in advance.

er, actually the applet does not seem to load at all.
But from what you have written, yeah, I need to
process the user's input and in my case, his
selected/choosen options in a menu.
E.g, the user wants to create a forum, he/she chooses
the create forum option from the menu which is part of
the shell and something happens which allows the user
to customise the forum.
So, let me get this straight, I can create an applet
and run the shell on the applet and the user can view
this application without downloading anything? As YAT said...providing they have the java plugin...yes... if you keep it to java.applet.Applet (AWT) and not JApplet, you should even have more users able to run it without 'downloading' anything..
Now..to be clear... they ARE downloading your .class files, and running them within a JVM on their own local machine... But they will not need anything (assuming their browser supports the Java version you write in) else...

I need help getting this program to work.

K. I don't pay much attention in my AP Comp Science Class.. but my teacher said if i can get this program to work i get an a for the semester... The program is Metrowerks Codewarrior IDE.. we are running it on windows 98 i think. She said she can't get it to compile.. so i guess it just needs to be able to input simple java programs (i.e. loops, just the regular crap) and compile them and run them...i have no clue what is wrong with it.. it could just need a patch...or we may just be going about it the wrong way...any help would be SUPER appreciated...
