whether we can call DTS directly from Java.Solution which we got as below:-
1. Create dts
2. Create job in which we have to call dts
3. Call job from stored procedure
It pretty lengthy process and we are not sure how error handling can be done in this scenario.
I create 2 files:
CircleCalculationMethod.javaMain.java
In Main.java, How can i call method in CircleCalculationMethod.java ?
Should I put everything in same folder ??Should i do something like "import CircleCalculationMethod.java"Should i do something like create a package ...
I use Eclipse software
We are using MS SQL server 2000, in which we have explored calling dtsrun.exe from Runtime class in java. But it is not suggested way to call dts, as error handling will be difficult.
whether we can call DTS directly from Java.
I am trying to call a java method in jsp. The main idea is to hide menu based on the user who logs in. The java class flows like this :
public class UserVerification {
public static void main(String[] args) {
UserVerification obj = new UserVerification();
System.out.print(obj.GetUserVerification("abc"));
[Code] ......
I used java and jsf. I created dynamic datatable in java file. Can i call java method from setOnchange() event?
I am able to call java script function from setOnchange() event. See the below code which is working fine for java script.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("openWin(this);IGNORE_UN LOAD=false");
I wrote openwin() function in java script. But i am not able to call java method change().
Code which is not working.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("myclass.change();IGNORE _UNLOAD=false");
myclass is the bean of class Test. If user select any value from dropdown i want to call change java method. This function will apply the same selected dropdown value to the other record also.
I am new to Java and have been learning it. I have a question here. I came across the following Java class and trying to understand it thoroughly but got confused how it is able to call an abstract method. Here is the code I am referring to :
package sampleapps.gui;
import javax.swing.*;
import java.awt.*;
public class InnerClassAnimationExample {
int x=70, y=70;
public static void main(String[] args) {
[Code] ....
So, in the code above, there is an inner class NewMyDrawPanel which has a paintComponent(Graphics g) method. I have highlighted 2 lines of code above.
Line 1 : Graphics2D g2d = (Graphics2D) g;
Line 2 : g2d.fillOval(x,y,40,40);
I understand we are type casting reference g to Graphics2D reference g2d and we are calling fillOval() method on g2d. I don't see a fillOval() method in Graphics2D class but it is there in Graphics class and fillOval method is an abstract method.
So, my question here is :
1. If we are not able to instantiate an abstract class(Graphics2D and Graphics classes), how are we able to access the fillOval() abstract method,
2. Secondly, since the fillOval() method is an abstract method, it does not have any implementation for the method.
However, when I call the method fillOval() on Graphics2D reference, I was able to draw and fill an oval of the specified co-ordinates. So, where would the actual implementation code be?
I have a EAR file which has a java class file and EAR file is deployed in weblogic.I have to call the java class of EAR file from a standalone java code which is present inside a JAR.While making the call to EAR i have to pass a parameter from JAR to one of the methods of class file which is present in EAR.
View Replies View RelatedI have to call a java method using only varags in its prototype :
public void _instanceMethod(Object... obj) {
....
}
that is equivalent to :
public void _instanceMethod(Object obj1, Object obj1, ..., Object objn) {
....
}
My question is simple : I only own a List<Object>How can I set each element of _instanceMethod parameter from my List ?? If i decided to iterate through my list such as :
for (Object obj : myList){
_instanceMethod(obj);
}
How can I correctly "populate" the _instanceMethod varargs signaturee by the n elements of my list ?
I am having problems in creating an age calculator in java. The only input is your name and date of birth. It means I need to incorporate the current date and make conditions. I am only allowed to use BufferedReader, InputStreamReader and IOException for import. I need to start with this and just add the conditions,
import java.io.InputStreamReader;
import java.io.IOException;
import java.io.BufferedReader;
public class ageactivity
{
public static void main (String[] args) throws IOException
{
BufferedReader br = new BufferedReader (new InputStreamReader (System.in));

I tried to add conditions but its not calculating the days.
We are in the process of developing a e-commerce application. It is a web site for a book shop. It is a site very similar to Amazon.com where you can order books online. Front end is in Java Technology. There is however a concern about where to put the business logic.
I am suggesting to put all business logic in the Oracle Database, as stored procedures (i.e. packages). However, one of my colleague says that when you call a Oracle stored procedure from Java, it takes 2 round trips, one to validate the procedure and then to validate the input / ouput parameters of the procedure.
In a website application like what we are trying to build, is it sound advice to put all business logic in the DB? Or should it be in the middle tier (app. server) programmed in Java? Or should you spread in between the middle tier and DB? If so how?
I am trying to make a 2d graphical animation using the java swing classes in order to make a frame. I had a basic version working when all of the code was under the main method, but when I moved some into another method it broke it. With y understanding of java my code should work as I create a variable of the method containing the code and then assign the size and exit button. However this causes many problems such as my BeaconFrame method informing me that it is unused when I have used it. Here is my code:
import javax.swing.*;
import java.awt.*;
public class BelishaBeacon {
public void BeaconFrame() {
JFrame frame = new JFrame();
JPanel panel1 = new JPanel();

I'm new to Java. I need to run a SQL server stored procedure(that creates a unique job number) from Oracle SQL Developer (JDBC) in Java. The same Java code will be used in Applescript to run the SP.

I have a question about a method I have. In my game, I had a move method to move my player left and right, and originally this method was huge, as it also took care checking collisions and a few other things. I broke it up a bit and put the collisions in their own methods and call them from again another method... Here is an extract which I hope illustrates my point:
private static final double MOVE_SPEED = 0.2;
private static final double MAX_MOVE_SPEED = 3.5;
private static final double STOP_SPEED = 0.18;
private double xPos;
private double yPos;
[Code] .....
Something I thought might be a good idea is to check the direction collision when im doing the calculations for that direction:
if(moveLeft) {
dx -= MOVE_SPEED;
(dx < -MAX_MOVE_SPEED) {
dx = -MAX_MOVE_SPEED;
}
checkLeft();
}
But then I would also need to check it when I'm slowing down the left movement:
if(dx < 0.0) {
dx += STOP_SPEED;
if(dx > 0.0) {
dx = 0.0;
}
checkLeft();
}
Then I thought instead i can check it after both of these steps:
if(moveLeft || dx < 0.0) {
checkLeft();
}
I guess my question is quite general: How much is acceptable to break up a method? How many chains of method calls is acceptable? Is it ok to call the same method from different nearby places?
I am newbie in java and little bit known to apex. I write an java code and compile it to class file. Now i want to call that class file from an push of button on apex. When button is pushed i need some arguments to be password to java class files . For arguments i need to take the item value from the apex page.
But i stuck on how to call that java class file from apex. On command prompt when i ran java class file, its working.
my first assignment is to convert a md5 string to password of the user, the MD5 function is available, i just need to call it and print the result. Here is my code. I can't call the md5 because of the String[] and String is different in main and md5 function,modify the code so it can run properly, also the input has to be entered from command line.
import java.security.*;
public class PasswordCracker {
public static void main (String[] args){
String password;
md5(args)
System.out.printf(""+password+"");

I have two comboBoxes - one in main and another in my 'windows' class. The code below is in main and references the comboBox in main but I need to use the comboBoxEnv out of my 'windows' class. How can I do that so it says ComboBoxEnv rather than comboBox?
JMenuItem menuExport = new JMenuItem("Export");
menuExport.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if(comboBox.getSelectedItem() == null){

I've gotten access to it by changing my code and making a method of it but I'm not sure of what I do now
exportImport.comboBoxEnv();

I have written a java app that's been working for a few years now and the client is very satisfied. However, a certain user has been experiencing a problem where the app runs fine BUT whenever it interacts with the OS (Win7 in this case), it takes ~10 mins to respond. Actions include, for example, exporting the currently displayed JTable to a CSV file or making an OS call to open up MS Word, etc.
I copied the users version of the app onto my platform (win 8.1) and tested it on winXP too with no problems which points towards an issue on the users particular PC. Furthermore, it used to run on the users PC fine until something (??) happened.
I've tried the following so far:-
1. looked at System restore to check anything new installed - nothing obvious
2. disabling anti virus - problem still occurs
3. monitoring JVM process time using Task Manager - little CPU time seems to be utilised (=> no loop etc)
I'll try :-
1. using JvisualVM - although I don't think this will show me what's going on with the OS
2. excluding the JVM and the app from all anti malware
Any app or something that shows interaction with the OS so I can trace what might be intercepting the call from my app to the OS?
How do i call the method without using inner classes in this example:
jt = new JTable (model) {
public boolean isCellEditable (int row, int col) {
if (col == 5) {
return false;
