JSP :: How To Set Scripting-invalid True
May 12, 2014
I was trying to set scripting-invalid true , but even after setting it to true I am able to use scripting. This is the web.xml under WEB-INF
<web-app>
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>
true
</scripting-invalid>
</jsp-property-group>
</jsp-config>
</web-app>
And This is the jsp page
<html>
<body>
<!-- Here I am going to use scripting like scriptlet,expression and other element like jsp declaration element -->
<%!int i=0;%>
<%System.out.println("Scriptlet");%>
<%=new String("Expression")%>
</body>
</html>
Why its not working ?

I need fixing an issue in the search textbox in one of the jsp's. I was informed that cross site scripting can be done in the textbox and I kept the below code in my jsp to fix the issue:
Java Code:
searchTerm = request.getParameter("search");
searchTerm = searchTerm.replaceAll("<", "<").replaceAll(">", ">");
searchTerm = searchTerm.replaceAll("[^A-Za-z0-9 ]", "");
searchTerm = searchTerm.replaceAll("eval((.*))", "");
searchTerm = searchTerm.replaceAll("["'][s]*((?i)javascript):(.*)["']", """");
[Code] ....
Now, after applying the above code, the cross site scripting can be done and the problem is that the search can't be done using the textbox and all the time will display none results.

My goal is to ask them for their name and if they got it right then it says yes while if they wrote it wrong, it would say no.
Java Code: public static void main(String[] args) {
Scanner name = new Scanner(System.in);
System.out.println("What is your name?");
String sname = name.nextLine();
name.close();
System.out.println("Are you sure it's " + sname + "?");
Scanner tfname = new Scanner(System.in);
String stfname = tfname.next();
[code]....

Currently experiencing this issue where my IF statement never gets evaluated to 'true'.
public static void search(SalesEmployee[] employeeArray, int searchID)
{
for(int i = 0; i < employeeArray.length; i++) {
String e = ("" + employeeArray[i].getId());
if(e.equals(searchID)) {
System.out.println(employeeArray[i].toString());
}
}
}//end of search

I have a piece of code for an applet that I want to run as the main applet code, and I want it to loop until a boolean is true, but it needs to paint while the code is looping. Here is the relevant part of my code ....
public void paint(Graphics g)
{
g.drawImage(background, 0, 0, this);
if(over == false)
{
tick();
[Code] ....
(I have tried replacing the if with a for, that does not work.)

I have a problem with an if statement I've done. I'm not sure how to fix my problem. I'll post the code of the if statement and the output.
if (box = true &&(shippingSwitch ==1))
{
if (ounces < .5)
{
additionalPrice = ((ounces % .5)/(0.0625))*1.25;
shippingPrice = 15.75 + additionalPrice;//((weight / 8)+ (weight % 8));
[Code] ....
Here's the output I get using println to test it.
Please enter 1 if your package is a letter and 2 if your package is a box
2
Please enter weight in pounds (Example: 1.2):
1.2
Please enter your shipping service option:
Press 1 for Next Day Priority:
Press 2 for Next Day Standard:
Press 3 for Two Day Shipping:
1
7.00
If I comment out the else statement on the last line of code I get the following output:
Please enter 1 if your package is a letter and 2 if your package is a box
2
Please enter weight in pounds (Example: 1.2):
1.2
Please enter your shipping service option:
Press 1 for Next Day Priority:
Press 2 for Next Day Standard:
Press 3 for Two Day Shipping:
1
13.75
What I want to happen is the code under the first comment to to execute if true, or go to the code under the next comments and execute if that statement is true and if that is not true I want the last block of code to execute underneath the last comments.

I have the code and it works very well, but my professor wants us to use Junit testing to test our code. I've never used JUnit before, how it works. Is it possible to have a boolean value (true or false) randomly set?
Here is the code I need to test:
package musicalinstruments;
class MusicalInstrument {
public String name;
public boolean isPlaying;
public boolean isTuned;
public MusicalInstrument(){
isPlaying = false;
isTuned = false;

So, I don't know how to start off this program. I'm not looking for the final answer, but I don't know two things: 1. the objective, 2. what type of thing do I start it off with? A method? I'm pretty sure it's not a class right because it already has a class?
public class WebFarm
{
private ArrayList<Server> servers;
/* constructors and other methods and instance variables not shown */
}
public class Server
[Code] ....
the Instructions:
The ping() method of the Server class returns true if the server is currently functioning normally; otherwise it returns false. Write a definition for the needsAttention() method of WebFarm that returns an ArrayList containing the servers that are not functioning normally:
public ArrayList<Server> needsAttention()
{
//I can put code here
}

Create an application that generates a quiz. Prompt for the user's first and last name, college major, and confidence in test taking (high, medium, or low). The quiz should contain at least five true/false questions about horticulture. When the user selects the correct answer, a message of positive reinforcement should be displayed. If the user selects the incorrect answer, the correct answer should be displayed with a message of constructive criticism. At the end of the quiz, display the number of correct and incorrect answers as well as the percentage of correct responses for each user.
import java.util.Scanner;
class HorticultureQuiz {

I'm supposed to take this truth table and alter it so it displays 1's and 0's instead of true false. I'm assumed to do this I would just need to change the variable type and replace true and false with 1 and 0 but every way I try this does not work.
//a truth table for the logical operators.
class LogicalOpTable {
public static void main(String args[]) {
boolean p, q;
System.out.println("P Q AND OR XOR NOT");
p = true; q = true;
System.out.print(p + " " + q +" ");

I'm creating a 4x4 2D array. I need to be notified, or gain a value when all elements have been turned true. Is this as simple as
"If the2DArray[] = true { blah blah }" ?

Assignment: Given an array of scores sorted in increasing order, return true if the array contains 3 adjacent scores that differ from each other by at most 2, such as with {3, 4, 5} or {3, 5, 5}.
scoresClump({3, 4, 5}) → true
scoresClump({3, 4, 6}) → false
scoresClump({1, 3, 5, 5}) → true
Codingbat AP-1 3rd question
public boolean scoresClump(int[] scores) {
for (int i = 0; i < scores.length; i++) {
int a = scores[i];
int b = scores[i + 1];
int c = scores[i + 2];
if (Math.abs(b-a) + Math.abs (c-b) <=2)
return true;
}
return false;
}
I got it right for some of the input, but not one of them. I tried to use the for loop and if statement on a specific input that I got wrong:
{4, 5, 8}
scores[1] - scores[0] = 1
scores[2] - scores[1] = 3
I suspect it has something to do with the for loop, but I don't see the problem with it. It should work, shouldn't it?
But anyway, here is the error for {4,5,8} :
Exception:java.lang.ArrayIndexOutOfBoundsException : 3 (line number:7)

Code in the book is written exactly like this:
import java.util.Scanner;
public class AdditionQuiz {
public static void main (String[] args){
//Generate random two integers using utility System.currentTimeMillis
int n1 = (int)(System.currentTimeMillis() % 10);
int n2 = (int)(System.currentTimeMillis() / 7 % 10);
[Code] ....
however the true/false result can not be printed due to the "answer" variable...

Code below:

jScrollPane2.setVisible(true);
table_001.setVisible(true);
try {
PreparedStatement st =conn.prepareStatement(SQLTextEditor.getText());

Given an array of scores, return true if each score is equal or greater than the one before. The array will be length 2 or more.
scoresIncreasing({1, 3, 4}) → true
scoresIncreasing({1, 3, 2}) → false
scoresIncreasing({1, 1, 4}) → true
Java Code:
public boolean scoresIncreasing(int[] scores)
{
for (int i = 0; i< scores.length-1; i++) {
if (scores[i] < scores[i+1] || scores[i] == scores [i+1]) {
return true;
} else {
return false;
}
}
return false;
}
Unsure what the problem is, it will always return True for some reason...

I am kind of new to programming in java and I am trying to run a first time setup type of thing for my program so I am saving the settings to a file. If the file doesn't exist I want it to run the first time setup but if the file does exist I want it to skip that process. My problem is that .exists() says reads true whether the file is there or is not there.
public static void main(String[] args)throws IOException{
new Window(); //Runs the Window()
PrintWriter writer = new PrintWriter(path);
boolean bool = new File("path.txt").exists();
System.out.println(bool);

How do I make it so that if both numbers are entered between 10 and 20 it will print false?
The assignment: Ask the user to enter 2 ints. Output "true" if one of them is in the range 10 - 20 inclusive, but not both. Otherwise output "false"
12 99 → true
21 20 → true
8 99 → false
15 17 → false
import java.util.Scanner;
public class Practice {
public static void main(String[] args) {
//get user input
Scanner user_input = new Scanner(System.in);
System.out.print("Enter a number: " );

I am new to Java and would like to ask how to do this question specifically:
Code a Java method that accepts a String array and a String. The method should return true if the string can be found as an element of the array and false otherwise. Test your method by calling it from the main method which supplies its two parameters (no user input required). Use an array initialiser list to initialise the array you pass. Test thoroughly.
