EJB / EE :: Inquire To Get Some Queue Statistics Like Current And Max Depth
Apr 7, 2014
In weblogic deployment, I have my MQ profile defined which creates weblogic.jms.PooledConnectionFactory. I want to Inquire to get some queue statistics like Current depth and max depth. If I have MQQueueConnectionFactory/MQQueueManager, I can do this with MQQueue INQUIRE but I am not able to find a solution for this from PooledConnectionFactory.
Is there a way to convert PooledConnectionFactory to MQQueueManager/MQQueueConnectionFactory or is there any other way to INQUIRE from PooledConnectionFactory.

I made a heads or tails game but I'm getting a bug when the user says he doesn't want to play anymore. The statistics are printed as many times as the games played. If you want to test the code, write" cap" " pajura" and when the program says "Vrei sa mai joci?" that means "do you wanna play another one?" and you can answer with "da"(yes) or "nu"(nu) Here is the code:
import java.util.Scanner;
public class cap_sau_pajura{
private static int user;
private static int pc;
private static String converted;
static int usermove;
private static int castiguri = 0;
private static int pierderi = 0;

I have a list of people with a matching telephone extension number, the people are organised in a hierachy tree with some colleagues at the same level and then some junior colleagues. I have been trying to write code that can find the tree height of any given member but I am unable too. Here is my code so far but the left and right are not working because I have not declared them any where in my code.
Java Code:
//hierarchy rank section 7
// **Depth** from node to root (bottom up)
public int rank(Member p1){
//to do

I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.

This program is for a swimming pool filling service company. They charge 2 cents per gallon and $50 per hour to fill a pool. The truck can fill at a rate of 730 gallons per hour.
Create the Pool class that calculates the cost to fill a pool based on it's Shape, length, width and depth. (Input order is S L W D)
The pool class will need data fields for String shape, double length, double width, double depth, static double GallonsPerSqFoot = 7.4805, static double price per gallon = .02, static double FillingFeePerHour = 50.0, and static double FillingRate = 730gal/hr.
Create a No-Arg constructor and a constructor that accepts the non-static values, and has the methods: getShape, getLength, getWidth, getDepth, getGallons, getHours, getFillingFeePerHour, getHourlyCost and getTotalCost.
At the end of the class, create a main() method that asks for the input and returns the output based on the Pool class gets.. methods.
The shape options are oblong or rectangle. (A round pool would be oblong with the same width and height, a square pool would have the same width and height)
Formulas:
Rectangle cubic ft = length * width * depth.
Oblong cubic ft= ((Math.PI * Math.pow(width/2,2)* depth) +((length-width) * width * depth))
Gallons = cubic ft * 7.4805.
hours = total gallons/730.
Total cost = (total Gallons * .02)+(hours * $50)
Example Output
An oblong pool 18.00 feet long by 12.00 feet wide and 5.00 feet deep will use 6923.10 gallons of water and take 9.48 hours to fill. The total cost will be 612.65.
Here is my code:
import java.util.Scanner;
import java.util.*;
public class Pool
{
private String poolshape1 = "oblong";
private String poolshape1 = "rectangle";
private double length;
private double width;
private double depth;
private static double GallonsPerSqFoot = 7.4805;

I am trying to get the current utc date/time, but it keeps printing out in local time:
Java Code: LocalDateTime dt = LocalDateTime.now();
ZonedDateTime zdt = dt.atZone(ZoneOffset.UTC);
System.out.println("time: " + zdt);
// output:
time: 2014-06-02T13:37:55.705Z mh_sh_highlight_all('java');
13:37 is local time. Utc time is 17:37.

import java.util.Scanner;
public class Swipe_In {
public String DTStart; //Swipe in Date Time
[code]....
I have got 2 questions on the above class...
1) I get an error "Cannot make a static reference to the non-static field DTStart" wherever i use DTStart in the main method....What's causing this error? and How do i fix it for good?
2) public String DTStart; Once i get the current date & time assigned to the above DTStart String in the main method i cannot use the updated value of DTStart in any other class. In another class i wanna create an instance(object) of this Swipe_In class with DTStart assigned to the current time(as in its main method)..I tried but the object's DTStart gets assigned to null.(( How do i achieve this?

I'm working on a project for class that asks me to record punch-in and punch-out times for employees. However, I am having difficulty figuring out where I am going wrong as none of the information will write to the text file in the ArrayList that I have created. The code is as follows:
import java.text.*;
import java.util.*;
import java.io.*;
import java.nio.file.*;
public class TimeClockApp {
// declare class variables
private static EmployeeDAO employeeDAO = null;
[Code] .....
I want to keep the coding as simple as possible as I am new to Java, and have spent hours upon hours trying to figure this all out. The console output looks like this:
Welcome to the Punch-In/Punch-Out Screen
Please choose an option below:
I. Punch In
O. Punch Out
Choice: i
PUNCH IN
--------
Enter Employee ID:
8
8Punch-In Date & Time: 2014/05/28 22:44:26

My primary question is about which method is the best for having an applet of mine communication with a backend database of mine. In other words, I don't want to try learning a technology that is out of date or not a good fit for my goal. I purchased the O'Reilly title "Java Servlet Programming", but it seems to be very old and out of date (referencing Netscape 4, etc.) and I see a Java RMI O'Reilly title on Amazon, but it was written in 2001.
My basic goal is to allow my applet to have access to a back-end database for reading and writing. I understand that direct Applet to DB (via JDBC) access is a bad idea so my thought is to create a servlet (much like web service for lack of a better term) or an actual web service (RESTful would be my first guess) to broker the requests. I already have a very basic servlet running that has access to my database server so now I want to focus on the best method for making calls from the applet to the servlet but having said that I don't want to go down this road too far if a servlet is not the right tool for the job.
My reading has been leading me to RMI, but as I said, I don't want to focus on that if there is a better option. In a non-Java environment, I'd use a web service (REST, SOAP, etc.) and perhaps that's what I should do here as well and not even bother with a servlet per se and just go with a web service.I know there can be some subjectivity with regard to these choices and I don't need to know what the "best" one is.I don't want to use RMI if it's dead or has been surpassed by something else, for example.
Should I use a servlet? Should I use a web service? My needs are rather modest; query the database, send updates to the database, etc. Nothing too crazy.

So basically we have this question to do : Write a method dayNumber that determines the number of days in a year up to and including the current day. The method should have three int parameters: year, month, and day. If the value of any parameter is invalid, the method should print a warning message and return the value zero. The table gives some examples of the action of the method. Accept any non-negative year as being valid. You may want to assume the existence of a method numberOfDays that returns the number of days in a given month of a given year. And you should have a method call isLeapYear, if the user enter a year that is a leap year.
This is what I did so far:
class dayMonthYear {
public static void main(String[] args) {
System.out.println("Enter a year");
int year = In.getInt();
System.out.println("Enter the month for '1' to be January - '12' to be december");
[Code] ....
It works and compiles but my problem is that: let say I enter "12" for December and December has 31 days, so what my program will do since December has 31 days, it thinks each month has 31 days and add them up which will give me 372 when it's suppose to give me 365. How do I make it that it won't do that and that it will work if the year is a leap year too.

I want to know if I can get the entire log4j.properties file constructed in Java code. I am not talking about configuring the logger using Java code.I have a logger that is already configured using a file. I want to get access to either Logger or LogManager (any other?) class and print the current configuration that is in memory.

Is it possible to define the same message driven bean as a listener to different queues?
The goal being to define different redelivery configuration for different kind of messages, but handle them all through a single deployment MDB for unity/entity purposes.
The other option is to have many MDBs targeted to the same source code.
