My code is:
Logout.jsp:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP Page</title>
[Code] ....
how to resolve this?

View Replies View RelatedI have a project in java that asks me to load some information from previous object files and add new objects to them afterwards. I created the files, but when I close the program and search for the previous information that should've been saved in the object file , it return nothing.
Here is the code.
Add method:
public boolean addUser (User u){
users[Ucount]=u;
Ucount++;
return true;
}
The save method:
public void saveUser (){
try{
FileOutputStream FOS = new FileOutputStream("User.txt", true);
ObjectOutputStream OOS = new ObjectOutputStream (FOS);
[Code] ....
The read method:
public void readUser (){
try{
FileInputStream FIS = new FileInputStream ("User.txt");
ObjectInputStream OIS = new ObjectInputStream (FIS);
for (int i=0;i<Ucount;i++){
[Code] ....
*Note: When I open the object file I could see that the information are actually there, so I think there's a problem with the read method I'm not sure what it is.
I'm having trouble to compare two string from my LinkedList. I took me 2 days now trying figure out how to compare the current string to previous string in the linkedlist. Here is my code.

String comparableHead = data.toLowerCase();
return (myHead.compareTo(comparableHead));

I am trying to use iText to create a PDF document. I found a nice tutorial online but one thing stumps me. How do I get the URL of the JSP page that contains the content? Since this will not be static, I don't want to hard code this. I am sure this is something simple but I am fairly new to servlets and JSP.
String File_To_Convert = "test.htm";
How do I get the url of the JSP page?
I have 3 issues -
1-I'd to be able to refresh my page. currently I've set it so it doesn't refresh so I can draw but I want to introduce timed refreshment for example after 30 seconds of drawing the page goes blank and starts again.
2- I'd like to introduce a maximum amount you can draw per each refreshment. E.g the page reloads every 30 seconds and each 30 seconds you have 100 ellipses you can draw, when it refreshes you have a new 100 ellipses
My code below...
PImage bg;
int cNum = 1;
void setup() {
// Images must be in the "data" directory to load correctly
size(1200, 800);
bg = loadImage("User_T_1.jpg");

View Replies View RelatedI have a assignment in which the code has to scrape a web page for a little bit of data including the link to the next page, follow the link, and do this 100 times. It is scraping all the data correctly, including the link, but it isn't following the link to scrape the data on that next page. Instead, it is displaying the first page's data 100 times. I have the code in a while loop where it reads in one character at a time from the page into a string and then uses pattern matching to get the data and the next link from the string. Then it correctly displays the data and should loop back to connect to that next link and read one character at a time into the string and so on.
I have printed the link to the console and it is good. I don't get any errors. I just can't figure out where exactly the problem is. Here is my code:
import java.awt.*;
import java.io.*;
import java.net.*;
import java.util.regex.*;
import javax.swing.* ;
public class SimpleWebSourceGetter{
static void getSourceCode(String url) {
String mystring = "";

I am calling a jsp page from my servlet using the requestdispatcher.forward(myjsp.jsp) method. myjsp.jsp is creating a new thread which is parallely processing along with the servlet. The issue is that the jsp page is not displayed until the servlet finishes its execution, although the new thread is created by jsp and is executing in parallel. How do we have the jsp page displayed even when the servlet is executing.

First the user shall authenticate with a tan

View Replies View RelatedI am trying to have a program go on one of the stock trading websites and read the number a stock or currency is at and display or save it. I have it reading and displaying the binary code but I don't see how to have it find the numbers I would like to get.
On the site you would have to go on the page and click some tabs to trade and maybe the stock you would like, it doesn't really matter what one it returns as this is more just an idea. Although I would like to have it search out a selected stock eventually to take it to the net level. I think my biggest problem is I can't see how to access the stock numbers in the code. I looked for different click events but don't see how to have a program do this.
I do not intend to have it display all the code like it is now. I just did it like that to see what I was getting. I will just have a small toolbar with options and a display.
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;

I just want to know how can i move to another jsp page from my servlet.
I know that there are 9 implicit objects that are available in a JSP page , except the page implicit object every object has certain utility ,but i am not able to understand the usage of a 'page' implicit object.
I've read it is actually an object of the servlet which is obtained after compiling this JSP page ,moreover a reference of Object class hold this 'page' object so there are only those 11 legacy methods of Object class which anyone can invoke on it and even if the 'page' object is typecasted to our generated servlet class it will also be of no use until there are any instance methods or fields(which are not Thread-safe) declared through <jsp:declaration> tag ,and writing instance method through jsp:declaration will again bring us to the old discussion of avoiding java code from JSPs..
