I have an ecommerce site that has about 100000 SKUs. What is the best practice for handling all the product images as far as where to store them and how to display them on the pages? Should I have a separate HTTP server to serve the images?

This is my class with the GUI:
import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JPasswordField;

Eclipse error message:
Exception in thread "main" java.lang.NullPointerException

i think the problem is to do with my images not being recognised. I put them in my source in User>...>workspace>src which is correct as far as i know. From what i know the images should show up if i look at my src file in eclipse but they dont. I tried changing the file type from .png to .jpg but it makes no difference.
So the user is on a website and I want them to go to another site using the same browser and tab.Can this be done in java? And yes the java program is running on the browser .
View Replies View RelatedI 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.
I'm looking for a way to gather data from a site page. all data is shown in the same page... I am trying to get the content and parse it is a bit crazy as data seems to be not organized. Itried to get it as a document but still looks crazy.
As all data is shown very clearly in the page (I would like every row to be an object) I'm sure there is some way to collect this data easily. (the data is from this page: [URL] ....)
I'll attach a snapshot and the content I got from the website.

In my EJB modules, to prevent that any JPA exception is ever thrown, I check the condition that would cause the exception beforehand. For example, the exception javax.persistence.EntityExistsException is never thrown because, before persisting the entity, I check if such primary key already exists in the DB. Is it the right way to do this?
Another approach is too allow the JPA exceptions to be thrown and catch them in a try-catch block, and then throw my custom exception from the "catch" block. However it requires to call EntityManager.flush () at the end of the "try" block. Otherwise the exception throw could be deferred and never be caught by my block.

View Replies View Relatedhow we can handle the string with special characters. For instance:
123456789BNJKNBJNBJKJKBNJKBJKNBJK"VJKNBJNHBJNJKBVJ KBJKNB"VHBVBBVNBVNBVBVBVBNBVNBNBJHFBVFJB FNVJBNVJNVJDFNVJKNVJKNVJKVNNVJ NN"
I get some user inputs with double quotes and i need to split to 80 chars line.
.length fails to get the length if it contains special characters like double quotes and ?
So my question is simply about how to best lay out my code so that each classes are talking to each other in the best way possible. I have a habit of creating a "handler" that just holds instances of either class and make them interact such as a player/map handler, that holds an instance of a player & map and then checks things such as collisions, though i'm not sure if this is the best practice. i'm just trying to make sure i'm always laying out my code the best way I can as I tend to get a little messy

I have come across some code where it attempts to save an entity to a database, but before it does it validates that the name of the entity is unique. If it is not unique it throws a runtime exception. This results in the ugly default exception web page being displayed. Is there any way to propagate this back to the JSF page where the user enters and clicks the form button to save the entity? The page already handles some error cases such as "field required" using the h:inputText's 'required' attribute. Need something more for name validation.
View Replies View RelatedEvery type of controllable object in my game is a type of Entity, and so extends Entity. This is broken down into Ship(s) and Structure(s). But I have different types of structures as well. The problem is that I use an ArrayList<Structure> to store all of a team's structures, but I need to be able to loop through that, and still be able to reference the subclasses of those structures.
For example, I have a JumpGate, which extends Structure. I need to be able to reference a particular JumpGate - as a JumpGate - and not as a Structure. However, the way that I cycle through all of the different types of structures is with an ArrayList<Structure>. I could get around this by having an ArrayList<JumpGate>, however, I would then need a seperate ArrayList for every type of Structure, which would get messy.
How is this possible? Here is the servlet page.

* Servlet implementation class InvoicingDeptServlet

I have a project that is asking me to create a program that will handle a Golfer and his scores. The program will be comprised of three classes: a Golfer class that will manage all the golfer's scores, a Score class and a Tester class to drive the other classes. To accomplish this task the program will use a partially filled array to store the golfer's scores. I have the majority of the code written. It compiles fine, but when I compile and run it only gives the following output.
Tiger ID Number: 1001 Home Course: Pebble Beach
Score Date Course Course Rating Course Slope
[LScore;@15db9742
I am not sure what I am doing wrong. I have been over and over the code. It is also only printing one golfers information. I have tried creating a for loop for the for the toString in the Golfer class but I am getting the following error Golfer.java:117: error: missing return statement.
I am at a loss here is the code I have for the three sections.
public class Golfer
{
private String name;
private String homeCourse;
private int idNum;
private Score[] scores;
private static int nextIDNum = 1000;

View Replies View RelatedI want to ask if there is an option to set the vertical position of the node handles of the TreeView-control.
I used a custom TreeCell factory with icons of sizes between 24 and 64 pixel and the location of the handle is regardless of the size of the icon on top of the cell. So if you got large icons the view did not look so nice.What I want is a property or something to center the handle in the cell depending on the size of the cell. Is there such an option?
I have a page which lists items using a ui:repeat. The repeat is surrounded by my h:form tag.
Now I have made it so that when click an item, then I load some item details - render them in their own xhtml file and inject the result into the dom tree.
This is causing some problems.
* My injected content has commandButtons and commandLinks which do not work because I don't have a form in my injected page - since this would cause nested forms :-(
* tried to replace commandButtons and commandLinks and instead create unique url's that I can call to get my work done - but how to I then re-render a panelGroup on then page? tried using jsf.ajax.request but I'm not able to get part of the page (a shoppingcart) to update
Basic outline
<h:form>
<table>
<ui:repeat ...>
<tr><td onclick="...">Click here to load item details</td></tr><tr><td id="itemDetailPlaceholder"></td></tr>
</ui:repeat>
</table>
</h:form>
Having with LSL and JSF working together? The only thing I have gotten to work with LSL is PHP, and I know I could get JSP working with it with a little research. However, I rather not mix them on my server.
The only requirement for LSL to work with it is there needs be a custom page that can handle get and post request directly. I have not done this with JSF yet so I'm wondering how that would look.
