Need help for CCVP CERTIFICATION

Hi. I am a CCNP certified person. I would like to lear CCVP. Is it possible to learn CCVP without any voice backround. Is it possible to get voice knowledge by reading books? if so pls recommend some books which will be helpful for me to learn voice over ip and its related ccvp papers. i will be greatful to you
thanks
esa

It will be very difficult, though not impossible, to achieve CCVP with no voice experience. The value of doing this would certainly come into question. I would recommend finding a position where you can gain experience or building a lab for experience. Nothing replaces getting your hands on the equipment. That being said, reading will start you down the right path and give you some knowledge of voice protocols, QoS, etc. Please find a list of books and a link to some good information on Cisco's website below.

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

Need Help for Java Homework Assignment, Can someone Please help me ?

This is the program that I am supposed to write, and I am terrible confused, as it takes at least 3 different files.
Write a class named GroceryList that representss a person's list of items to buy from the market, and another class named GroceryItemOrder that represents a request to purchase a particular item in a given quantity. (I.E. four boxes of cookies).
**The GroceryList class should use an array field to store the grocery items, as well as keeping track of its size (number of items in the list so far). Assume that a grocery list will have no more than 10 items. A GrocerList object should have the following methods:
public GroceryList()
Constructs a new empty grocery list.
public void add(GroceryItemOrder item)
Adds the given item order to this list, if the list is not full (i.e., has fewer than 10 items).
public double getTotalCost()
Returns the total sum of all grocery item orders in this list.
The GroceryItemOrder class should store an item quantity and a price per unit. A GroceryItemOrder object should have the following methods:
public GrocerItemOrder(String name, int quantity, double pricePerUnit)
Constructs an item order to purchase the item with the given name, in the given quantity, which costs the given pricer per unit.
public double getCost()
Returns the total cost of this item in its given quantity. I.E. 4 boxes of cookies that cost 2.30 per unit, have a total cost of 9.20.
public void setQuantity(int quantity)
Sets the grocery item's quantity to be the given value.
Any suggestions would be sincerely appreciated.
Thanks.

Pete,
I having difficulty with the main class, and getting console to store a users input into a string array ... I will post the code that I have so far. Sorry I am trying real hard to learn ... and just having a frustrating time.
This is what I have in the main file.
import java.util.*;
public class Chapter_8 {
     public static void main(String []args){
          Scanner console = new Scanner(System.in);
          System.out.println("Please enter the first item of your list");
          String[]GroceryList = console.next();
          System.out.println("Please enter the next item of your list");
          String[]GroceryList = console.next();
          System.out.println("How many would you like to buy?");
          int quantity = consolenextInt();
     }This is what I have in the GroceryItem Class file:
public class GroceryList{
public GroceryList(){
Static String []GroceryList ={"beans", "macaroni", "milk", "cheese", "bread", "eggs","hamburger","Hotdogs","peas","cookies"};
for(int i=0;i<5;i++){
System.out.println(GroceryList);
And the final file that I have is the GroceryItemOrder Class file:public GroceryItemOrder(String name, int quantity, double pricePerUnit){
this.name = name;
this.quantity = quantity;
this.pricePerUnit = pricePerUnit;
public double getCost(){
public void setQuantity(int quantity){
Sorry, I know it isn't much, that's why I am frustrated.
Thanks.

Need help for Java Programming asap plzzzzzzzzzzzzz

Here is the work: (Im writing it coz I wasn't able to attach it)
Introduction
In geometry, a straight line is the shortest distance between two points.
A line may be characterised by its end points and its length.
A line connects the points P1 and P2.
The point P1 has coordinates {X1,Y1}.
The point P2 has coordinates {X2,Y2}.
The length of the line joining P1 and P2 is given by the equation:
{ (X2 - X1)2 + (Y2 - Y1)2 }1/2
Those of you who are familiar with geometry will recognise the equation as being the well known Pythagoras equation for the hypotenuse of right angled triangles.
Requirements
Develop a class specification for the class Point.
Write a short test program and test plan for this class.
For example:
//pointTest.java
main(...)
Point P1;
P1.create(24,16); // create a point with coordinates {24,16}
P1.display(); // display the {X,Y} coordinates of P1
Develop a class specification for the class Line.
Write a short test program and test plan for this class.
For example:
//lineTest.java
main(...)
Point P1 = new Point();
P1.create(24,16); // create a point with coordinates {24,16}
Point P2 = new Point();
P2.create(33,42); // create a point with coordinates {33,42}
Line L1 = new Line();
L1.create(P1,P2); // create a line using points P1 and P2
System.out.println( L1.length() ); // display the length of line L1
Line L2 = new Line();
L2.create(12,30,28,16); // create a line using coordinates {12,30}, {28,16}
L2.display(); // display the coordinates of both points and the length of the line
Application
We wish to determine the length of the boundary of any regular or irregular polygon .
The polygon may have up to 6 sides.
The user should be prompted to enter the number of sides and the coordinates of each vertex point.
The program should then calculate and display the total length of the boundary.
You should write an application to implement this using your Point and Line classes.
What I should have at the end
The following:
? A listing of the files Point.java, the class test program and results.
? A listing of the files Line.java, the class test program and results.
? The application program and results.
Note 1: All code must be written in java.

Point P1 = new Point();
P1.create(24,16); // create a point with coordinates {24,16}That's a terrible idea. If that was actually in your requirements, then whoever wrote it should stop teaching Java right now.
We have constructors to initialize objects with sensible, meaningful values. Creating a new Point object without any values and then calling a "create()" method to set the values is a pretty stupid approach. Not only does it ignore the usefulness of a constructor, it also ignores the convention that methods called "create" should actually create something (and not just set values).

Need help for java and linux

Hi, guys,
I am being involved in a project.My current task is to build an interface using java. This interface will obtain some information from a linux-based software called NistNet, which is done by C and has GUI as well. My question is, can I use this java-based interface to obtain some information that is typed in this NistNet'GUI? If I can, how can I do that?
Any hint available?
Thanks!

You can bridge between Java and C using the "Java Native Interface" (JNI). There used to be a good tutorial on this site but it vanished for no apparent reason in some resent update, so try a websearch.

You haven't posted ANY 'java program' for us to help with.
The forum is NOT a coding service. It is to help you with YOUR code.
Post the code you have written and SHOW us (don't just tell us) how you compile it and execute it and the results you get. Then we can help you with any problems you are are having.
If you need help understanding just what the program should be doing you need to ask your instructor to clarify the assignment.

Hello Experts,
I have report where users can input the company, housebank, account ID and posting date.

but how do I link it with the proper bank and account?
For example:
                   Cash in Bank
Bank A
Account ID 1     1,000,000
Account ID 2     25,000,000
Hope you can help me guys. Thank you and take care!

hi Viraylab,
each house bank you can find in table T012, in T012K you'll find the bank accounts to the housebank, the G/L account will be in T012K-HKONT.

Need help for flash builder

i need help for flash builder 4 and papervison 3d. I need to create a slider with it ranges of value from 10 to 50 to adjust the camera values for the camera.fov and also need to create it for the yaw of the object from 0 to 360. I try to look for any slider event and classes in this program but cant find any, btw, i need to use the AS only project file.
here is my codes:
can you please tell me how i should modify the codes?
package
    import flash.display.BitmapData;
    import flash.display.Sprite;
    import flash.events.Event;
    import org.papervision3d.materials.BitmapFileMaterial;
    import org.papervision3d.materials.BitmapMaterial;
    import org.papervision3d.objects.primitives.Sphere;
    import org.papervision3d.view.BasicView;
    [SWF (width="800", height="600", backgroundColor="0x000000",frameRate="30")]
    public class EarthBitmap extends BasicView
        private var sphere:Sphere;
        public function EarthBitmap()
            super(800 , 600);
            var earthmaterial:BitmapFileMaterial = new BitmapFileMaterial("../assets/Earth.jpg");
            sphere = new Sphere(earthmaterial,100,20,18);
            camera.fov = 25;
            scene.addChild(sphere);
            addEventListener(Event.ENTER_FRAME,rotateSphere);
        public function rotateSphere(evt:Event):void
            sphere.yaw(0.2);
            singleRender();

Turn the click handler into a full on separate function. Then store all the views in an array and use Math.rand() to randomly choose one.
Something like this:
<fx:Script>
     <![CDATA[
          var questionsArray:Array = {question2,question3,question5,questionRed,questionGeography};
          function buttonClickHandler(event:MouseEvent){
               var randomProblem:int = Math.floor(Math.random()*(questionsArray.length));     //generates a random integer between 0 and the total number of questions in the array (arrays are 0-based)
               navigator.pushView(questionsArray[randomProblem]);
     ]]>
</fx:Script>
<s:Button id="randomProblemButton" label="Next Problem" click="buttonClickHandler(event)" />
Haven't tested that, but something along that line should work
