In Java, is there a way to force a JVM instance to run on a single CPU/Core.
Additionally is there a way for given thread to figure out what CPU it is running on?
What is the recommended way of setting GET query parameters on a Restlet Request object?
I think I can see how to get them out of the request using getQueryAsForm(), but how do they get set in the first place?
At the moment, I am adding them manually to the URL using a StringBuilder and java.net.URLEncoder, but it seems like there should be a better way.
I have imported a GWT project from GIT , but when i run maven Install
it says
.m2\repository\commons-logging\commons-logging\1.1\commons-logging-1.1.jar; cannot read zip file entry
and if i simply run my application , i get this
\git\my-Search-Engine\qsse\war}: java.lang.NoClassDefFoundError: com/google/inject/servlet/GuiceServletContextListener

but if i do that i start gettin the exception
ava.lang.NoClassDefFoundError: com/google/inject/Injector
any idea how can i resolve this
I need a 'java' source code on how to extract a cap file from the computer and divide it into blocks in order to send it using APDUs to the smart card to install or load or delete an application. Thanks in advance.
I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?
Suppose I'm running several servers serving basic requests on my local network (say a home network, where all machines generally have an IP in the form K.K.K.x, where x is variable). Is there an easy way to discover all such servers? I would need to find each IP on the network running a particular java server application.

Hi,
ok it is 'easy' to make jna wrapper solution for mapping exported functions within dll using jna:
long f1(int x), just int

Please don't say cpp code should be rewritten to avoid this:-)
Quick question:

Hi, I am a C++ / Java programmer and the main paradigm I happen to use in everyday programming is OOP. In some thread I read a comment that Type classes are more intuitive in nature than OOP. Can someone explain the concept of type classes in simple words so that an OOP guy like me can understand it?

Hello,
Is there a command in java for conversion of an ArrayList into a object array. I know how to do this copying each object from the arrayList into the object array, but I was wondering if would it be done automatically.
I want something like this:
ArrayList<TypeA> a;
// Let's imagine "a" was filled with TypeA objects
TypeA[] array = MagicalCommand(a);
I want to create a simple clock using Java. The code is so simple that I will give an example:
for(int i=0;i<=60;i++)
jLabel11.setText( Integer.toString(i) );
The problem is while I'm running my program the result didn't show each update in sequence.
It show only the 60 digit immediately, without showing the change from 1 to 2 to 3 ...
How can i fix this problem?
I'm working on a project for school in Java programming. I need to design a GUI that will take in questions and answers and store them in a file. It should be able to contain an unlimited number of questions. We have covered binary I/O.
How do I write the input they give to a file? How would I go about having them add multiple questions from this GUI?
package multiplechoice;
import java.awt.*;
import javax.swing.*;
public class MultipleChoice extends JFrame {
public MultipleChoice() {
/*
* Setting Layout
*/
setLayout(new GridLayout(10,10));
/*
* First Question
*/
add(new JLabel("What is the category of the question?: "));
JTextField category = new JTextField();
add(category);
add(new JLabel("Please enter the question you wish to ask: "));
JTextField question = new JTextField();
add(question);
add(new JLabel("Please enter the correct answer: "));
JTextField correctAnswer = new JTextField();
add(correctAnswer);
add(new JLabel("Please enter a reccomended answer to display: "));
JTextField reccomendedAnswer = new JTextField();
add(reccomendedAnswer);
add(new JLabel("Please enter a choice for multiple choice option "
+ "A"));
JTextField A = new JTextField();
add(A);
add(new JLabel("Please enter a choice for multiple choice option "
+ "B"));
JTextField B = new JTextField();
add(B);
add(new JLabel("Please enter a choice for multiple choice option "
+ "C"));
JTextField C = new JTextField();
add(C);
add(new JLabel("Please enter a choice for multiple choice option "
+ "D"));
JTextField D = new JTextField();
add(D);
add(new JButton("Compile Questions"));
add(new JButton("Next Question"));
}
public static void main(String[] args) {
/*
* Creating JFrame to contain questions
*/
FinalProject frame = new FinalProject();
// FileOutputStream output = new FileOutputStream("Questions.dat");
JPanel panel = new JPanel();
// button.setLayout();
// frame.add(panel);
panel.setSize(100,100);
// button.setPreferredSize(new Dimension(100,100));
frame.setTitle("FinalProject");
frame.setSize(600, 400);
frame.setLocationRelativeTo(null); // Center the frame
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}

In Eclipse (and Flash/Flex Builder) you get the option with Ctrl+Shift+F to do a file search and look for a regular expression. Would be a real handy thing to know.
I want to find the word negate if it appears in a Flex/java comment like the following:
// It was negated because
or
/*
The negate option was....
*/
or
/**
* We have to negate the value
*/
Any ideas? Will test them out at http://www.regexplanet.com/simple/index.html
I have a JSplitPane which when shown should split the pane by 50%.
Now on giving an argument of 0.5 (as suggested) to setDividerLocation, Java seems to treat it as a normal number instead of a percentage. As in, the divider, instead of going to the middle of the pane, is almost at the start of the left pane (the pane is vertically split).
Any work arounds?
I want a simple client that takes a few parameters (Method, URL, Parameters), makes an HTTP request, and shows me the results that were returned.
A browser obviously can easily send GET and POST requests, but I have no good ideas on DELETE and UPDATE.
Did I miss something in browser 101, or is there a common freeware tool to do this? I've seen other threads that give me Java APIs for a simple client, but that's not what I'm looking for.
