I am trying web service first time so want to client application which will consume webservice which are hosted online for testing purpose
now i want to call some methods defined in this wsdl [URL]....
can anyone tell how should i invoke methods using stand alone java file no eclipse which jar files should i use ?
I have a single class application which works well in the Eclipse console. But how do I turn it into a Jar file?
View Replies View RelatedI need to invoke a restful webservice Client(Rest) from my Webapp based on some scheduler . Also I need to persist the data which the webservice returns in response. So basically-
1. Scheduler triggers, I need to build the rest service request (JSON) and invoke it.
2. Capture the response of the webservice and persist the data in DB.

I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.
Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.
Java Code:
import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

View Replies View RelatedI have a given WSDL file (around 1MB) and inside of the file they have many request and response types.
I have to generate JAR from it so I could import it on my current project and use it
I have tried using this: [URL]....
but it only generated 1 stub file and a 1 callback handler java files and its size is around 60MB.
WHat I need to is to generate seperate class file per response / request type... Is there a way to do it?

So far this is the code I have. It will successfully read the contents of the file(which are below in quotations) and write them to the designated file. My issue is totaling the corresponding costs to their services and then writing that to the file. The if and else if clauses above do not work but how is it that I can get them working?

I am trying to build and IDE for NASM in Java for Ubuntu. There are other IDE's for NASM but they are in C or C++. So i thought i should try making one in Java. Well I am done with the GUI part.
How should i link the NASM compiler to the IDE.
Or
There is another way like "DEV C++ IDE" does in Windows is that it invokes the CMD and runs it in that so i could try doing something like that by invoking the TERMINAL in Ubuntu and running it in that. Does java have an API for this purpose.
I'm pretty new to Java. I was working the project about gamble. I'm having trouble with invoking the void method from another class. This is what I have done so far.
There are two classes, and I'm trying to invoke gambleAnotherRound method from gambler class into highlighted part in casino class. So, what I want to do is when the program generates "else" part, it goes back into another gamble round.
public class gambler {
public void gambleAnotherRound(double dollarsBet) {
dollarsSpent += dollarsBet;
Random randomNumbers = new Random();
double randomDouble = randomNumbers.nextDouble();
[Code] ....
Below one is casino class.
// use a System.out.print statement to ask how much money each gambler should bet.
// Then declare a variable dollarsBet of type double, and set its value to the keyboard's
// keystroke (be sure to use keyboard.nextDouble()).
// If the user enters 0, then issue a break statement, so that the while loop terminates
// Else, invoke the gambleAnotherRound method of each Gambler, and pass it the variable dollarsBet

this is the problem Write a Java project with two different classes.

I had to write a class called Thermometer, that has one instance variable (an integer) for the temperature in Fahrenheit. I had to include the following methods
-a constructor that initializes the temperature to 60
-there is a method to change the temperature
-there is a method to display the temperature
-there is a method to reset the teperature to 60
Here is the code for that.
public class Thermometer {
private int temp;
private int thermometer;
public Thermometer() {
thermometer = 60;
[code]....
Now I get to the issue. I have to write a test class called thermometer to test the thermometer class. I need to test each method while displaying the temperature after it. My professor said I should use the invoke method but didn't go into much more detail than that.
Here is my problem:

method countMail!! Also the text file you are reading from is attached as ampo_uumail.txt and i also have a picture of the output.
For the unit 3 assignment, you must develop a program. that reads the file icecream.dat. This file is supplied in the Files for Unit 3 Assignment directory in Unit 3. You must use TextIO methods to read the file. As you read the file, count the total number of ice cream cones that were sold. (This is the same as the number of lines that you read from the file.) Also count the total number of "Strawberry" cones that were sold.
At the end of the program, print out the total number of cones, the number of Strawberry cones, and the percentage of cones that were Strawberry.To do this program, you have to know when to stop reading from the file. TextIO has a function named TextIO.eof() to check whether the entire file has been read. The value of this function is true if the entire file has been read. The value is false if there is more data in the file. You want to continue reading from the file as long as TextIO.eof() is false.
Note: Suppose that flavor is a variable of type String and you want to test whether its value is "Strawberry". To do this, test whether flavor.equals("Strawberry"). (Do not use == to test for equality of Strings.)
Each line of the file icecream.dat is an ice cream flavor such as "Vanilla" or "Strawberry." A line represents the sale of one ice cream cone of the given flavor.
You must complete your program, test, debug, and execute it. You must submit your java code file. The output of your program must be captured by either copying the content in the output window and pasting it into a text document that you submit along with your java code file, or by capturing the image of the screen which contains the output of your java program. In windows you can capture a screen shot with the Ctrl Alt and Print Screen key sequence. This image can then be pasted into a Word, WordPad, or OpenOffice document which can be submitted with your assignment.
For students using the programr service online. Make sure that you create both the TextIO.java and the icecream.dat files as java project files. I found it was easier to rename icecream.dat to icecream.txt for some reason. For students using Netbeans, use the same set of rules that were defined in Unit 2 to setup your project and incude the TextIO.java file as we did in unit 2. Also make sure that you copy the icecream.dat file into your project directory so that it can be found by your java program.
I'm wondering about the use of exceptions to handle errors that might occur during file I/O when the I/O is done by a method implementing an interface's method. The idea is for the interface to provide a uniform way for application code to read (and write, though I'm not addressing that in this post) a document from a file, given a File object that specifies the on-disk location of the document. The "document" can be an instance of any class the application programmer wants it to be, provided that it can be created from a file stored on disk. Here's the interface definition:
public interface DocumentRamrod<T>
{
public T openDocumentFile(File file) throws FileNotFoundException;
}
A simple implementation, when T is a class that just holds a String, might look like this (Please overlook the fact that there is no call to the BufferedReader's close method, as it's not needed for this example.):
public class MyRamrod implements DocumentRamrod<OneLineOfText>
{
public OneLineOfText openDocumentFile(File file) throws FileNotFoundException
{
return new OneLineOfText(new BufferedReader(new FileReader(file)).readLine());
}
}
But, that one line where the file is read (Line 5) might generate an IOException.To cope with it, I could add a try-catch to the implementation like this:
public class MyRamrod implements DocumentRamrod<OneLineOfText>
{
public OneLineOfText openDocumentFile(File file) throws FileNotFoundException
{
try
{
return new OneLineOfText(new BufferedReader(new FileReader(file)).readLine());
} catch (IOException ex)
{
Logger.getLogger(MyRamrod.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Or, I could add that to the list of exceptions defined for the method in the interface, like this:
public interface DocumentRamrod<T>
{
public T openDocumentFile(File file) throws FileNotFoundException, IOException
}
But that's where I'm getting nervous, as it makes me realize that, with an infinite number of possible implementations of openDocumentFile, I can't predict what all the exceptions thrown might be.should I have openDocumentFile simply throw Exception, and let the application programmer sort out which one(s) might actually be thrown, should I keep listing them as it become clear which ones are likely to be thrown, or should I not have openDocumentFile throw any exceptions and let the application programmer deal with it in the implementation of openDocumentFile (with try-catch blocks, etc.)? In Good Old C, I'd have passed back a null to indicate some general failure, with the various callers up the call-stack having to either deal with it or pass that back themselves (until some routine up the stack finally did deal with it), but that seems like an approach the whole exception mechanism was designed to avoid.
I'm thinking the right choice is to have openDocumentFile throw Exception, and let the application programmers decide which subclasses of Exception they really want to deal with. But I have learned to be humble about the things I think, where Java is concerned,
I am wanting to override certain methods in some Minecraft class files, and tell those class files to use code from my class files.
And no, I don't mean extend a class. When I try to extend from the main Block.Class, it makes that file as another block file for the game, or something.
So like, I want to tell the main file that handles block registries to use the code from my class file to register my custom blocks to the list of blocks, but without modifying that main block file.
Is this even something that's possible?
Also, I know that the way a file is named affects the loading order. My class files would be named using symbols to make it load right before the class file I want to override.
I am trying to load a CSS file from a mySql DB table (each row represent a customer that use the application, and each one can set his own CSS file).
How can I convert the Stream / String that I loaded from the Clob column to something that I can use here XXXX
scene().getStylesheets().add( XXXX );
I found alot of examples, but they all talking about files from filesystem, or URLs. My CSS file is in the application memory. I want to prevent the option to write my string as a new file and then read it again. I have no problem with loading the CSS file from database, this part is O.K.
