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'm working on an applet for my class. I decided to use AWT even though it's really old.
I'm having trouble with the labels on my program. They don't show up until I click another tab in the browser and then go back to it each time after I click on a button. I tried to use repaint() but it doesn't seem to work. What can I do?
I am trying to pass parameters from he following HTML file to an applet. the applet is not initializing and the iam getting the following error on the console. I also have both the html file and and the java applet under the same source file in eclipse.
java.lang.NumberFormatException: null at java.lang.Integer.parseInt(Integer.java:542) at java.lang.Integer.parseInt(Integer.java:615) at applet.DisplayMessage.init(DisplayMessage.java:16) at sun.applet.AppletPanel.run(AppletPanel.java:434) at java.lang.Thread.run(Thread.java:745)
Here is the html file
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title>
I work on SSH for creating a external tool to manage remote OS.
I find out the JSch library and i create the java GUI project as jar application, and worked for me very well. (i am working on Netbeans ).
I introduce the JSch library with Netbeans as follow. Right click on the Project-> Properties -> Libraries ->Compile ->Add JAR/Folder.
After that i try to transform the project to applet in order to work it form web server.
I made the transformation in all the code.
When i run the applet through the Netbeans it worked for me. When i build the project to create the jar file.
I create a folder with the my.jar file, index.html, a folder named (lib) which contains the jsch-0.1.50.jar file.
Then try to run the index.html, the GUI appear but cannot connect to the remote with the SSH, and does not give any error.
I think that the problem is that my.jar cannot communicate with the jsch-0.1.50.jar.
Why the project runs trough the Netbeans an does not run when i call it from the next html code.
index.html
Java Code:
<Html> <Head> <Title>Java Example</Title> </Head> <Body> This is my page<br> Below you see an applet<br> <br> <Applet Code="AppletUI.class" archive="my.jar" width=600 Height=700> </Applet> <Body> </Body> </Html> mh_sh_highlight_all('java');
I have created a simple applet application that is embedded in a HTML. When I did compiled it, I received an error of ClassNotFoundException. I'm using Jdeveloper11gR1. Please see screenshot.
This is my error :
java.lang.ClassNotFoundException: cams.gsis.applet.CAMSApplet at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
[Code] ....
And this is my Error on java console.

I have an applet which I want to embed into HTML. In applet viewer in Eclipse IDE the view is this(see pict01), and when I access my index.php on local server I get this view(see pict02). I don't know what I am doing wrong. I checked it with Firefox, IE and chrome. No changes. Here is source code:
import java.util.*; import java.io.*; import javax.swing.*; import java.awt.*; import java.applet.*; import java.net.URL; public class WCURL extends JApplet {
//static final int WIDTH = 8; //static final int HEIGHT = 12;
[Code] ......
I have these files in my local servers folder where I am trying to access it from(see pict03).
I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException { int returnVal = fc.showSaveDialog(window); if (returnVal == JFileChooser.APPROVE_OPTION) { StyledDocument doc = (StyledDocument)text.getDocument(); HTMLEditorKit kit = new HTMLEditorKit(); BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
This is a college course assignment that consists of classes TotalSales and TotalSalesTest.In the main program I have created a two dimensional array to output a columnar layout with cross-totals in 4 rows and 5 columns. This program outputs sales totals by row for each sales person(1 - 4) and output by column for products(1 - 5). I have created extra elements in the array to store total for rows and columns. So far both classes compiles. The problem is that although the PrintWriter creates a notepad file, it doesn't print to it. I don't seem to understand the input and output methods completely. I finished another program similar to this using basically the same try and catch that read the file and printed out a document in notepad. Here is the code and I'll try include the input file.
import java.util.Scanner; import java.io.*; public class TotalSales { private int salesPerson; //declare class variable private int productNumber;//declare class variable
so i followed a tutorial on youtube called "Java Game Development with Slick" - by thenewboston,URL....okay, so i have made my game / program, and now i just want to export it to a jar file that people can double click and play..unfortunately when i double click the .jar file nothing happens...i get the little "loading" thingy on my courser but it disappears after about 5 seconds and then nothing happens :(the way i made it into a jar file is by doing the following:
-right clicked my java project.. -clicked on "export".. -clicked on java / Runnable JAR file -filled in the stuff, (JARs destination ect..) -pressed finish.. -then i got a jar file on my desktop and double clicked it....but as i said....nothing happens
I have two files - I can get the second one to populate with the first ones data and then delete the first one. I cannot get it to then rename itself to the name of the first file. It also only hits the 'rename' section of the code providing I place system.gc in otherwise it completely skips it.
I have a question about the following snippet concerning the steps the javac compiler follows to compile a program:
[...]at first, searching a class within a package is discussed if the latter doesn't contain a full package name[...]
It is a compile-time error if more than one class is found. (Classes must be unique, so the order of the import statements doesn't matter.)
The compiler goes one step further. It looks at the source files to see if the source is newer than the class file. If so, the source file is recompiled automatically. Recall that you can import only public classes from other packages. A source file can only contain one public class, and the names of the file and the public class must match. Therefore, the compiler can easily locate source files for public classes.
However, you can import nonpublic classes from the current package. These classes may be defined in source files with different names. If you import a class from the current package, the compiler searches all source files of the current package to see which one defines the class. I don't quite understand the red fragment. I wondered if the word "import" nonpublic classes from the current package weren't a synonym for the word "use", since why would we want to import a class from the same package when compiler searches the current package automatically anyway?
However I wanted to test nonpublic classes that are contained in source file which name doesn't match the class name:
NonpublicClass.java:
Java Code:
package com.work.company; class NonpublicClass { public void description() { System.out.println("Working!"); } } mh_sh_highlight_all('java');
[Code] ....
Everything's fine when the source file names are the same as above. However, when I change NonpublicClass.java to a different name, there's an error "cannot find symbol" in:
Java Code: NonpublicClass v = new NonpublicClass(); mh_sh_highlight_all('java');
I noticed that the class file for NonpublicClass isn't even generated so that's probably the cause. If I change to the directory of the package the NonpublicClass is contained in and compile it directly, i.e. issue for example:
I'm trying to read a xml file and delete it's contents. I do this by reading the file,writing it to a temp and then overwriting the original with the temp by renaming it
//overwrite original xml file with new file boolean successful = outputFile.renameTo(inputFile); System.out.println("success");
It does say the value of the local variable is not used however. I've debugged to ensure it hits the code it always prints out the line after too.It just does not overwrite my original xml file with the temp one.
It's had votes on stack so I thought that would of been reputableStack - overwrite but the second one got voted as a good answer. But still I would like to know if my code can work or not.
I am kind of new to programming in java and I am trying to run a first time setup type of thing for my program so I am saving the settings to a file. If the file doesn't exist I want it to run the first time setup but if the file does exist I want it to skip that process. My problem is that .exists() says reads true whether the file is there or is not there.
public static void main(String[] args)throws IOException{ new Window(); //Runs the Window() PrintWriter writer = new PrintWriter(path); boolean bool = new File("path.txt").exists(); System.out.println(bool); if(!new File("path.txt").exists()){
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.
import java.util.*; public class TestArithmetic { public static void main(String [] args) { Scanner console = new Scanner (System.in); System.out.println("Enter First Number"); int x1 = console.nextInt(); System.out.println("Enter Second Number");
I can't figure out how to complete the for loop for the forward method that needs to calculate each pixel on the path setting it to white, starting at location (x,y) and ending at r.
public class Turtle { private static BufferedImage img; private static int black = 0; private static int blue = 255; // 2^8-1 private static int green = 65280; //(2^8-1)*2^8 private static int red = 16711680; //(2^8-1)*2^16 private static int white = 16777215; // 2^24-1 private double x,y,theta; // what does a Turtle know? static // a static initializer list
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 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();
[Code] ....
I need to convert the sample download.jsp to html so that i can parse
I have one table in mysql in that some rows are there i want to retrieve all rows using servlet and jsp concept and i have done half of the way but not getting output it is showing some info and nothing getting printed on page except columns heading and here is my bean class..
public class TimeDetailBean { private Time intime; private Time outtime; private Date date; private String eid;
So this is probably pretty simple but I can't seem to figure it out. My teacher wants us to write a code that scans a text file, then outputs some text based information AND displays an applet bar graph of the data sorta like this for the text:
and then an applet thats the same info just a little more graphic. My code interprets the input well, but when i try to make an applet output, the code basically forgets all of my variables and starts anew (when i just state the public static graphic (paint) class after everything) OR it refuses to scan the input file (if i switch the public class from main.....throw ExceptionIO to just public class graphic(paint))
Also, as a side note, any way to have java automatically determine how many separate lines there are in a text file without me having to manually count them.
import java.util.Scanner; import javax.swing.JApplet; import java.awt.*; import java.io.*; public class Project2 extends JApplet {
