I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.
I have designed a login page for my project....which has username and password box....I have created a Table in Teradata which has username and password information....now i need to connect this html login page to Teradata database to validate the username and password.
would like to make .jar application, which will be able to sava data without using any database (Postgres...) but i dont know, what type of datastorage i should use to make the application portable. I just want to .jar file, which is capable works on any computer with java installed. Is there some option?
My current calculator (currently available on my site) launches your default webbrowser with the CalculatorHistory file allowing you to print through your browser, but I been working on self contain the html page in a the JEditorPane which is great it does what i want, so I started working on the printing side and I am stuck...
The code I have was from a example (modified) but when I run the code I get the following error:
Exception in thread "main" java.lang.IllegalArgumentException: services must be non-null and non-empty at javax.print.ServiceUI.printDialog(Unknown Source) at gcclinux.co.uk.PrintReport.main(PrintReport.java:28)
The Line 28 equals to PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
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 need to parse an html web page to extract specific information from the tags in Java. For example,
<b>Species </b> Strain </td>
I need to look for the Strain info (Strain is variable in length) in the page. The whole web page is stored as a huge string. I need a regular expression that can identify all the Species and retrieve their corresponding strain info. how to do this or can propose some clever string manipulation methods in Java.
I have a server written in java and can display html pages. but when i try to add css to the page the server doesnt use it.(not my code). Do you have to flag the browser to use css or something?
public class SimpleWebServer extends Thread { public static final String VERSION = "SimpleWebServer"; public static final Hashtable MIME_TYPES = new Hashtable(); static { String image = "image/"; MIME_TYPES.put(".gif", image + "gif"); MIME_TYPES.put(".jpg", image + "jpeg");
I am trying to make a calculator using Java GUI. I've managed to make an ActionListener and add it to a button, but I've made an error in my code that I'm unsure of how to solve. Because of how I've written the code, only one number can be placed in the text field. For example, the an ActionListener for the three button on the calculator was added to the button, but no matter how many times the user presses the button, only one 3 will appear in the text field. The code is below:
import javax.swing.*;//import the packages needed for gui import java.awt.*; import java.awt.event.*; public class Calculator { public static void main(String[] args) { JFrame window = new JFrame("Window");//makes a JFrame window.setSize(300,350);
[code].....
As you can see, because the compiler forces the String variable to be final, so when the user presses the button, the code simply shows how a space character and three character would look like, because the String variable can't change. How do I write my code so that every time the user presses the button, a character is added to the text field?
I want a completely unique GUI with unique buttons, like I could make it a giraffe if I wanted to! (not going to, but a giraffe seemed like a pretty irregular shape) ....
One of my assignments was to make a program that would read a sequence of names and then list them all.Just to be clear, it would read them all first, and then it would list them all at the same time.
i am trying to make a platform game in java and to do this im trying to make a scrolling bacground. i can get the background image to scroll. However, i cant get the image to scroll forever, here is the code.
GamePanel class ( the jpanel ) public class GamePanel extends JPanel implements ActionListener{ static ArrayList<BackGround> store = new ArrayList<BackGround>(); public GamePanel(){ setFocusable(true); Timer time = new Timer(5,this); time.start(); store.add(new BackGround(0,-200));
the problem i have is that i want the bacground to loop. however, once the first instance of the background is done scrolling it freezes and doesnt load anymore. here is the code for adding a new background to the list
so recently i made an applet and i was gonna put it up on my website when i got an error saying that java had blocked the applet duo to security thingys..sooo i looked in to it and i found out that apparently you need permission from java to run a applet or something like that, because there was a lot of viruses coming from there or something...
so does that mean only big game company's that can actually get permission by java make applets? are applets dead!? is there no other way to play java games in a browser!??!
example: i hava a table conex wich i inser on it two columns name and password i fill it by name : yosra password : lol name : najeh password :mdr
i don't know when i fill jTextfield of password and name correctly for ewp i put yosra as name and password as lol the loop continue to the next row and i show the two message dialog on netbeans about correct acces and refused access and the frame of my chatroom is opened
private void jButton1MouseClicked(java.awt.event.MouseEvent evt) { // TODO add your handling code here: String pass=new String(this.pass.getPassword()); String nam=this.name.getText(); acceder(nam,pass);
