JSF :: Jsf2 Search Results Not Displaying?
Apr 27, 2014
I develop a little app in javaee6 and jsf2. I have a search page which has a search form with 2 fields and a search button when i click search button the results should be displayed in searchresults page.
Here is my code,
search.xhtml page
<h:form id="searchform">
<h:inputText id="deptId" value="#{searchBean.departmentId}"></h:inputText>
<h:inputText id="deptName" value="#{searchBean.deparmentName}"></h:inputText>
<h:commandButton value="Click to Search" action="#{searchBean.searchEmployees}">
[code]...
Issue: searchresults page is is not displaying records though it fetched records from table I'm able to achieve this using search bean as session scope but i want to use the scope as Requestscope.

Is there a way that I can save a binary search algorithm to a text file or something, so that it will always contain more information? The reason why I ask this is because I have BST like project which is supposed to act the game Twenty Questions, were it asks a person 20 Q's until it guess the answer. However, although my project does not require you to save stuff to a file, I find it rather very useful and cool if I could do that.So for example it would start out something like this:
Think of an animal and I will guess it.
Does it have legs? YES
Is it a cat? YES
I win! Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Is it a snake? YES
I win! Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Is it a snake? NO
I give up. What is it? EARTHWORM
Please type a question whose answer is yes for an earthworm and no for a snake.
DOES IT LIVE UNDERGROUND?
Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Does it live underground? NO
Is it a snake? NO
I give up. What is it? FISH
Please type a question whose answer is yes for an earthworm and no for a snake.
DOES IT LIVE IN WATER?
Continue? NO
Good-bye.
However, if the user exits the program then everything will be lost and go to waste. So once again, is there a way that I can save all of these inputs to a file or something and then read it in again?

I have created a jsp file which does the simple task of reading data from a mysql database and displaying the results on a web page. Please see below:
<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

However, each time I run the jsp file in the browser with my localhost as server, I get an HTTP Status 500 error.

I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {
[Code] .....
"The problem is with the while loop, the one above is something I was experimenting with "

I'm trying to build a method that can search a binary search tree for a specific target and then return the number of probes it took to get there. It seems to me that the best way to do this would be a recursive search method and a counter that tracks the number of calls. But I'm struggling with how to implement this. Here's the code I have so far. what works/doesn't work with the method.
// Method to search the tree for a specific name and
// return the number of probes
public T search(BTNode<T> btNode) {

I need to print certain information from an arraylist depending on the arguments the method has. I'm trying to print the last 3 methods from the database class but nothing is printing and I don't know what the problem is.
package hw3;
import java.util.*;
public class Driver {
public static void main(String[] args){
/* Comments required
PersonFileReader pfr = new PersonFileReader("person.dat");
ArrayList<Person> testData = pfr.readData();
Database db = new Database(testData);
*/
[Code] .....
On the driver class I just print what the methods from the database class do.

I have the following
Java Code: list.stream().sorted((s, s1) -> s.getName().compareTo(s1.getName())).distinct(); mh_sh_highlight_all('java');
I want to save the results to a collection.
I saw an video tutorial on these by Oracle learning library and they mentioned an into(collection) method but I looked at the api and there isn't one.
How can I do it?

I wrote this small program to take an octal number from the user and convert it to decimal form.
import java.util.Scanner;
public class Decimal
{
public static void main (String args []) //gets octal number from user, later prints conversion
{
int octal;
[Code] .....
Some conversions work. For example, 77 will be correctly converted to 63, and 77777777 will be converted to 16777215. However, some conversions do not work. An example of this is 775002 gets converted to 74898.

I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.

I am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.
// Bookstore.java
// This program displays information on multiple books

I've recently started programming with lwjgl, playing around with some 3D graphics. I've built a house and now I'm trying to render a view looking straight onto the center of the roof, but with current configuration it's slightly off.
As you can see in the image the edges on the roof aren't perfetly straight which would be the case if I was looking straight to the center from a point on the roof normal vector. I'm using gluLookAt to get the view, using the following code:
gluLookAt(house.getRoofCenter().x + house.getRoofNormal().x * 0.25f,
house.getRoofCenter().y + house.getRoofNormal().y * 0.25f,
house.getRoofCenter().z + house.getRoofNormal().z * 0.25f,
house.getRoofCenter().x, house.getRoofCenter().y, house.getRoofCenter().z, 0.0f, 1.0f, 0.0f);
And for the normals:
Vector3f.sub(p2, p1, a);
Vector3f.sub(p3, p1, B)/>/>/>;
Vector3f.cross(a, b, c);
roofNormal = new Vector3f(-c.x, -c.y, -c.z);
and center:
roofCenter = new Vector3f((p3.x + p1.x) / 2, (p3.y + p1.y) / 2, (p3.z + p1.z) / 2);
My question is: Is this due to errors in the rendering methods or is my math off?

Well, I have a list inside of a java class then i want to call that list into the jsp to show the results. That list has results from a query, everything is ok in java class because it shows me just one result in jsp, i read that it can be do with a for or enhanced for but been honest i have try everything and nothing work.
To import the class i did this.
<%@ page import="servlet.promotion*" %>
And the For.
<% for (int i=0 ; promos.size() < i;i++) { %>
<tbody>
<td><input type="text" name="C1" value="<%=m1%>"readonly = "readonly"> </td>
.... .... ....
</tbody>
<% } %>
The list is called promos.

I can now call the DB on the query I want and return results. What I know want to do is build an array of the data, forward it to the JSP page and display the bits individually.
So THis is the Servlet I havce:
package com.journaldev.jdbc.datasource;
import java.awt.List;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
[code]...
I think It is to do either with the way I am adding the values to User or its the forward:
getServletConfig().getServletContext().getRequestDispatcher("/test.jsp").forward(request, response);
