E.g:
onblurr="check(this, '<%=company.getId()%>' );return false;"
doing this, function check(field, inputVal) {
alert("companyId:" + inputVal);
}
Gave me the alerted value as :
companyId:<%=company.getId()%>
instead, if the company.getId() --> 30
When I do like this, how to get the value 30 inside the function? i want companyId:30

I'm having an issue when I try to define a variable in a JSP scriptlet, and then in a separate scriptlet on the same page attempt to use the variable. It looks like it goes out of scope.
I also cannot reference a variable from a servlet in a JSP expression tag. So I've had to write the entire page basically in one scriptlet.
I'm using Tomcat 6.0.

When using trim-directive-whitespaces in a Tomcat 7 application this expression also get trimmed:
<div class="${item.view} ${item.className}">
resulting in the HTML
<div class="personchild">
instead of
<div class="person child">
On the other hand, when I first assign the expression to a varibale it's fine:
<c:set var="className" value="${item.view} ${item.className}"/>
<div class="${className}">
results in the desired HTML
<div class="person child">
Is this the intention of the trim whitespace directive or does this look like a bug?

I have the below code with spaces on uri and prefix (directive attribute).
<%@ taglib uri=" news.tld" prefix=" news" %>
how to fix without altering the JSP? Can i handle with web.xml or any other property available.
I have hundreds of jsp like this and wanted to handle without code fixes.
I tried JSP trimSpaces but it fixes the namespace but not the attributes.

May be I did not understand the meaning and usage of attribute "session" in page directive. My understanding is if session=false, in page directive, then the JSP page will not participate in the session. However, I have my welcomepage as below:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" session="true"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
........
.......
<%= session %>
<c:out value="${pageContext.request.session}"/>
if I choose session=true, then both ways of accessing session works , which means the JSP page participated in the session.
But if I change the session=false, then <%= session %> fails, but <c:out value="${pageContext.request.session}"/> does not fail.
how can c:out still show the session, when session = false

I am working on a text based adventure game. (This is NOT OOP at all) The problem comes in at my second if statement inside my loop, it is not adding 1 to my array locations[] it keep printing location[0] then a 1 at the end. Not really sure what is going on here. I would like it to when I type "Go north" it adds 1 to locations[]
E.G
locations[0]
Go north
locations[1]
go north
locations[2]

I'm really struggling adding JLabels to my GUI. The code is giving no errors but the JLables aren't showing up as I think I've done something else wrong. Here's my method for adding the JLabels:
public void showGraphics(){
for(int i=0; i<message.length(); i++){
if(message.charAt(i) == '#'){
JLabel localLabel = new JLabel("test label");
getContentPane().add(localLabel);
}
}
}
I think the problem might be to do with how the rest of the GUI is setup and the fact that I haven't specified where to add the JLabel just that I'm adding them.
Here's what my GUI looks like.
I want the JLabels above the JTextArea.

I have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product {
private String name;
private double weight;
private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel {
public productList (){
super();
}
public void addProduct (String name, double weight, double price, int code){
super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton();
getContentPane().add(addBasketItem);
addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.

I want to add validation to some of the elements in my constructor.
Person(String idIn, String nameIn, ) {

I want to be able to check that the data for the ID is limited to a certain collection of characters formatted in a certain. For example, I may wish to limit it to 5 lowercase letters or numbers, or a combination of both. How could I do this?

I am doing a few Spring tutorials and in eclipse and for each tutorial I have to right click my project, build path, and then add external archives and then select the spring JAR files I want to bring in and use before my project will successfully compile and run. I was just wondering is this required for every project or is there a way I can set eclipse up to look in these locations for every project without me having to explicitly tell it too?

I have been trying my hand at making 2d top down view games and have found myself repeatedly using the same code so i created a file with all the functions so when it is down i just import the jar and dont have to keep rewriting functions. I have trouble because the background is loaded on the screen and i dont know why as i didn't tell it to load. In fact I set the panels visiblity to false. Both of my classes are in the same package. Why I still get the Image.

I am trying to add two bytes together in binary. The problem is that I need to print the carryover also. The printed result should be 8-bits long if the byte or the integer converted in binary is less than 8-bits the empty space should be filled with 0-s. I figured out how to print and add them, the part with the filling the blank with 0-s too. how to print the carryover. For example:
byte x =15;
byte y =9;
the output will be :
00011110 - carryover
x 00001111
y + 00001001

00011000 - result

So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
Method 1:
View Class ActionListener method:
Java Code: public void addMovementListeners(ActionListener u, ActionListener d, ActionListener l, ActionListener r){
moveUp.addActionListener(u);
moveDown.addActionListener(d);
moveLeft.addActionListener(l);
moveRight.addActionListener(r);
[Code] ....
Which method is better? Is there another method that is even better than these two? Trying to get this MVC thing down.

I was assigned to create a program that opens up a window that asked the user for an input of 0-10. This input will create three windows with the correct number of rows and columns of JTextFields in the form of a matrix. the third window has a button that adds the two matrices (which also take user input) and adds them together and prints them in the correct matrix fields. I am having trouble declaring the 2d array from the user input and creating the windows with the correct amount of jtextfields to move on with my program.
