How To Compile Servlets In Command Prompt
Apr 14, 2014
I have set the CLASSPATH
(C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53libservlet-api.jar,
PATH(C:Program FilesJavajdk1.7.0_51in)
and JAVA_HOME
(C:Program FilesJavajdk1.7.0_51) environmental variable on my windows XP.
I installed tomcat server and its running fine. I made my first servlet(DemoServlet.java) in
C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INFclasses folder.
I made the XML file (web.xml) in C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INF folder. In command prompt I went to the classes folder
(C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INFclasses).
And tried to compile my servlet(javac DemoServlet.java) but it is showing file not found error. I am new to servlets.

I was wondering if their is an easily explainable way to convert a jar for a text-based game that runs off the command prompt into a executable. I would guess there probably is not and the game would have to run off of completely different commands, but I thought it couldn't hurt to ask.

I just created a Hello World program in Notepad, but command prompt still can't find it even when ran as administrator. I've even tried to use command line to run Hello World programs I've created with Eclipse but it still doesn't work. Here's proof I have JDK setup as PATH:
I've even tried having the JRE as path but that still doesn't solve my problem. I'm really trying to learn Java programming but this problem is holding me back.

I'm trying to compile one of my Selenium WebDriver .java files to run from the command line. Since it's just one file, I only need to compile the file into a .class file to run it from the cmd line. I don't need to make a .jar file.
The .java file runs fine inside Eclipse, so now I need to make it run from the windows command line.
I tried compiling it using
javac -classpath C:WDJarFilesselenium-server-standalone-2.42.2.jar TasksCreateAssignments.java
but got this error
TasksCreateAssignments.java:23: error: package org.apache.poi.hssf.usermodel does not exist
how can I can fix that?

I am wanting this program to prompt the user to enter a maximum value and a minimum value and the program should in theory generate a random number for the output. Here is my logic:
int maxRange1;
int minRange1;
static int range;
static Random gen;
Then in my mail argument:
gen = new Random();
Scanner input = new Scanner(System.in);
System.out.print("Enter the maximum number: ");
int maxRange1 = input.nextInt();
[Code] ....
I am able to return both the user prompts and get the inputted answer to appear but I am not getting a response for the prompt "The random number is: ".

I am suppose to design a problem the prompts the user to enter a String. Based on the input from the user, have the program prompt with a full description of the playing card entered. Below is a table of the notation and meaning:
Notation Meaning
A Ace
2...10 Card Values
J Jack
Q Queen
K King
D Diamonds
H Hearts
S Spades
C Clubs
Use the .charAt(...) to extract each character from the user's input and build a switch statement to determine the full description.
import java.util.Scanner;
public class PlayingCardIdentifier {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a card notation: ");
String s = input.nextLine();

Write a method named diceSum that prompts the user for a desired sum, then repeatedly rolls two six-sided dice until their sum is the desired sum. Here is the expected dialogue with the user:
Desired dice sum: 9
4 and 3 = 7
3 and 5 = 8
5 and 6 = 11
5 and 6 = 11
1 and 5 = 6
6 and 3 = 9
This is my code:
import java.util.Scanner;
import java.util.Random;
public class mod {
public static void main(String[] args) {
diceSum();
[Code] .....
it works for numbers 2 - 4, but any number from 5 - 12 just prints one output, which is not the correct desired sum.

I am having a problem with code that I've written, the problem occurs when I try to prompt for user input at the end of the first loop. What happens is the println fires but the prompt never does and it exits the loop.

public static void main( String[] arguments )

I am still relatively new to java and am working on a lab program. I have already met the requirements and am trying to spice my code up with a loop that prompts the user to say if the program should run again. This is what I have so far:
package lab2;
import java.util.Scanner;
public class OrderedPairTest{
public static void main(String[] args){
boolean retry = true;
while(retry == true){
[code]....
However, it is giving me an error after the user inputs "y" in for the answer to run again. What did I do wrong?
Error code is: Exception in thread "main" java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at lab2.OrderedPairTest.main(OrderedPairTest.java:11)
