Web Services :: Comparing Previously Downloaded Html File With New One
Dec 7, 2014
I have downloaded the target page's html-file successfully, but how can I find out WHEN that version had its latest update?
Here's how the page is downloaded:
public void dlPage(URL url) {
try {
br = new BufferedReader(new InputStreamReader(url.openStream()));
fileOut = new BufferedWriter(new FileWriter(url.getHost()+".html"));
while( (line=br.readLine() ) != null ) {
fileOut.write(line);
fileOut.write("
[Code
I was thinking of using URLConnection's method getLastModified() for comparison. But dont have a clue how to read it from this file. Am I perhaps solving the download-part incorrectly?
I am making a little game for my friend based on HTML and javascript and i was wondering how to play an audio file that i downloaded on to my computer without the user interacting. like a buzzer you would hear on jeopordy or something like that, creating a Wrong answer buzzer and a right answer buzzer into an if/else statement.
i downloaded a sample database code of an online payroll system. How can i assemble it to know how it works. the files include php and mysql files. it is to build an online payroll system
Logic her eis when user selects option1, it asks for user to enter name and as soon as user enters name, it should compar name to existing names in txt file. I have user while loop and for loop but for some reason, it doesnt compare properly as there seems to be some mistake in looping and it just read first line or you can say single line rather than comparing it with all lines in txt file. i have attached votes.txt file with this. Also, if user doesnt exists infile, it will ask user to enter vote as yes or no and add it to file and then count total number of Yes and No votes from file and compare them.
my votes.txt file looks as below with two columns namely (name and vote).
Hiren No samir yes bob no rikul no master yes patrick no summer yes bhanja no
import java.util.Scanner; import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; public class logBook { public static void main(String[] args) throws FileNotFoundException

So far this is the code I have. It will successfully read the contents of the file(which are below in quotations) and write them to the designated file. My issue is totaling the corresponding costs to their services and then writing that to the file. The if and else if clauses above do not work but how is it that I can get them working?

I edited some lines from "[URL] ...." and saved it as html file; now if a friend want to do a search in Wikipedia for cats, the edited page should show up instead of original page.Is there a way to do this using java script.
I just created an applet that I want to call from a html file.
The applet code looks like this (and works):
package jav12;
import java.awt.*; import javax.swing.*; public class Welcome extends JApplet { public Welcome(){ } public void init() { getContentPane().add(new Label("Yessss it works",Label.CENTER));
[Code] ....
When I click on the html file the content of the page is blocked and the applet isn't loaded. What can I do to fix this. I think it has something to do with rights. This is a crosspost to JApplet content blocked
I need to convert a .txt file to html text, where the first line is changed to have < h1 > < /h1 > around it and the rest is wrapped in < p > < /p > so for example I read a .txt file that says:
chapter 1
this is a sentence
it would output:
<h1>chapter 1</h1>
<p>this is a sentence</p>
here is what I have so far and I cannot get anything to output.
I compiled the applet, then put the applet in an HTML file using notepad and saved the html file in the right place for it to run correctly. The HTML file runs smoothly, but then it only shows the scrollbar part of my applet, and not the images or any text...
Why is This?????
Java Code:
import java.awt.*; import java.applet.Applet; import java.awt.event.*; import javax.swing.ImageIcon; public class Temperature_Convert extends Applet implements AdjustmentListener { private Image temp; private Scrollbar bar; private int old, newtemp = 0;
I need to get the html in string when i hit the hit the jsp in servlets basically i need to put the output of jsp in pdf file when i hit one link i need to download that data in pdf file. I am using itextpdf.
//Get the output stream for writing PDF object OutputStream outStream=pResponse.getOutputStream(); ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();

I need to convert the sample download.jsp to html so that i can parse
Does the following code, which gets a class from a remote server, caches the class on the client machine?
URL u = new URL("http://1.2.3.4:80/JavaClasses/MainClass.class"); InputStream input = u.openStream(); DataInputStream data = new DataInputStream(input); byte classBytes[] = downloadByteCodesFromURL(data); Class c = defineClass("MainClass", classBytes, 0, classBytes.length);
JFrame parentFrame = new JFrame(); File f12=new File("E: ewfile.txt"); JFileChooser fileChooser = new JFileChooser(); fileChooser.setSelectedFile(f12); fileChooser.setDialogTitle("Specify a file to save"); int userSelection = fileChooser.showSaveDialog(parentFrame);

I want to save selected text file as html file in target directory....
I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.
I wrote a code to download a zip file in jsp, but it is not working as expected, when i execute this following program i am able to download file with "download_all.jsp" name, but now original download file (/tmp/Download_All/1244687508907.Zip). The download_all.jsp is my jsp name which is having the following code. Here is the code snippet:
try { String filename = "/tmp/Download_All/1244687508907.Zip"; if(request.getParameter("filepath")!=null){ filename=request.getParameter("filepath"); } // set the http content type to "APPLICATION/OCTET-STREAM response.setContentType("APPLICATION/OCTET-STREAM");
I inherited a navigation system which is like this:
index.jsp homepage.jsp
When I click on the "view source" in the browser, I get two headers like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en_US"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <meta http-equiv="X-UA-Compatible" content="IE=edge">
[Code] ....
I know this is not good. I have inherited the nav system from someone else and I have a lot of complicated AJAX and JQuery going on inside my module. I am not sure how to resolve.
I'm trying to create an algorithm that compares the first names of two people, which goes ahead and cancels similar characters and then counts the remaining characters to give a 0 if the remaining characters are even and a 1 if the remaining characters odd.
