I want to do a Registration page on some website. i connected to mysql and creating some id like 1 and 2 like this , but i don't want like this. i want to generate v21001 and v21002 to generate on every registration.
View RepliesThe problem you have is that it doesn't produce a 4x4 array. For that you need more nested for loops.This is what I have tried so far:
import java.util.Scanner;
import java.util.Random;
public class challenged2e
{
static Scanner console = new Scanner(System.in);
public static int i=0;
public static void main (String args[])
[code]...
I get 21 errors and they all have to do with i and j.
code used to create watermark in text-field of any registration page?
View Replies View RelatedI need to count external hyperlinks to other web-sites on each page of the the web-site. I've found this code here on stackoverflow:
public class Scanner {
private HtmlProcessor hp;
private String baseUrl;
private int step = 0;
private List parsedLinks;
public Scanner(String baseUrl) {
[Code] .....
Also I've found other working code that uses standard Java but it counts links only in one web-page. Can't create pattern to look all pages on web-site yet.
I'm assigned along with two others to make this program for a project.
We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.
Suppose i am using useBean in one of the jsp to check for the user registration. suppose the url which is hit is simultaneously used by 4 users and suppose object type created i.e. ID is person .When the last user enters the details and submits the details a person has just submitted ,that is person id already created , then how the useBean will work in this scenario.

I have a project which has a set of configuration files, where each configuration file represents an environment specific configurations. In other words, I have 3 environments, development, staging, and production. The configuration for each environment is different, e.g. DB name, url etc.
Whenever I want to deploy the same code, on each environment, I have to manually generate environment specific .war file, so that it has environment specific configuration file in it.
What I am looking for is a kind of solution where i have to compile only once in maven and it generates only one .war file, which I can use on every environment. In other words, i want the environment specifi application server/tomcat to identify which configuration to pick.
That way, I'll be sure that we are deploying and testing the same .war file on every environment/application server.
How can i restructure the application to achieve this functionality?

I want to generate a new tile every 1,5,10,15 (please check the code to gain an understanding of where I'm going) the session last for 4m :20 sec, I need using the date package, I tried using the sleep method however I don't want to pause the whole thread, so I need setting up the time aspect of the key generation (assume all other code works).

View Replies View RelatedI am having a doubt about how to fix and what could be the code to generate a retroActive salary case in payroll generation. Upto last year(2013) it was working fine.Now it is 2014 and i am stuck as i am new to java.
The system is computing every value in yearly basis,but the inputs are in monthly basis.
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road. If you choose to cross, the outcomes for 0-2 are "You crossed safely." For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street." For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working. I have up to here:
import java.util.Random;
public class test4 {
public static void main(String[] args) {
Random random = new Random();
for(int i =0; i < 1; i++){
int num = random.nextInt(10) + 1;
System.out.println("The number of cars on the street are: " + num + "Do you wish to cross the road?");
}
}
}
I need to generate reports for huge data (around 2 to 5 lakh records) in different file formats (PDF , XLS , RTF , XML) in my web application.
Data will be fetched from database.
I have been searching for a best open source report generation tool and ended up on choosing on Dynamic Reports.
Aspose , is licensed and unluckily we could not afford to at this moment.
Whether i can use Dynamic Reports , or is there any other tool available.
I am writing a payroll program .The program generates random PPS numbers and then takes in users information and calculates the salary accordingly.

</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
