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.
View RepliesWe have a large applet based application with a current client-side minimum jar download size of ~4MB. If we put ALL of our class files into jars, that size will probably double. Most users only use a small portion of the class files for their particular tasks. Having ALL users download ALL the classes, compressed in jars, is extremely time consuming and a major problem after application updates due to the large number of users and the network load it would cause.
So after downloading some basic jars other needed individual class files are downloaded as and when requested by user. For signing applet, applet class files are moved to jar and this jar is signed with following attributes in manifest.
Jar file manifest:
Permissions: all-permissions
Codebase: *
Application-Name: XYZ
Application-Library-Allowable-Codebase: *
Trusted-Library: true
When applet is invoked from browser with JRE 1.7.51, there is a security blocked exception for individual files which are accessed from the signed applet jar. Why individual class files are blocked? Is it necessary to move all individual class files in a jar?
Is there anything wrong with writing JSP tags in psuedo-HTML? I've been writing tags in XHTML, but it would seem that XHTML could not be compliant with both an XHTML standard and the HTML5 standard.
View Replies View RelatedI do not think this is possible, but I'd like to confirm. If I have an HTML page that has an embedded Java applet, and that applet in turn renders an HTML document (within the applet window), is the HTML *within* the applet part of / accessible through the DOM for the parent page?

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;

View Replies View RelatedI am currently trying to update a few java applets for a website. As of right now, the applets are automatically blocked on all computers when they are accessed because the newest updates for Java have caused them to be blocked. I have determined that the solution to this is to resign the .jar files that are used to run the application with a new certificate.
I requested and received a certificate (in pkcs 12 format, a .p12 file), imported it into the computer, and used it to sign the .jar files. However, I have been getting an error after signing the .jar files stating that the full certificate chain of the code signing certificate is not valid.
I tried to check the path of the certificate using a method he recommended (using OpenSSL) but didn't really find anything of use.
You basically paste a url Into a textarea and choose an Image for the link.The Image link Is then appended to a html file.
I'd like to put everything In a single jar file but I'm not sure what to do so the user can access the html file.
The only two options I can think of are:
a) create the html document on the fly when the jar runs.
b) Is to run a bat command when the jar Is executed that will extract the jar files.
The user can either choose from a number of Images In the logos folder for common websites or add new Images. Since the folder isn't empty , It seems like extracting the jar files Is necessary.
So I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*;
public class Test{
public static void main(String[] args) throws IOException{
int x;
//create a new file internally called doc. But externally labelled the user input
File doc = new File(args[0]);

I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){
Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar");
}
I would then continue this on for Linux and Windows, but this limits my application.
How to create object for "class B" and call the "function_B" from other different class D where class D has no connection with class A? Here is my program.
public class A(){
void print(){}
}
class B{
void function_B(){}
}
class C{
void function_C(){}
}
Here, A, B, C are in the same package. But class D is in different package.
I will give an example below of what I am talking about. in C++ I know I would need a copy constructor because I would be pointing blindly in the heap if I deleted a object in the struct.
We have a Class/struct animal and three animals in that class/struct, a dog, a cat and a cow. Each animal has a baby and then I will give the animal a name in main. But if I delete one of the dogs puppies because I sold him wouldn't I being pointing off in the heap and have a leak?
Also since Java doesn't have structs can I put a class inside a class?
I want to know can we put the data of html file example
<html>
<body><applet code="classname" width="100" height="100">

We have a custom authorization in our application login page, authorization by using eToken and java (signed jar classes) and applet as login button on page. It's work fine on older and current java versions like 7u67, 7u71 but it's not work on new java version 8u25.
We write a test class named AuthControl without package, we found that problem is in .jar file path, for example:
&APPLET_VERSION. is a jar file name, uploaded using "Shared Components / Static Files - Create"
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {code:'AuthControl',
archive:'#WORKSPACE_IMAGES#&APPLET_VERSION.', width:132, height:37}; // problem in the path to the .jar file
var parameters = { scriptable:true, mode:'login' };
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>
Error is:
...
java.lang.ClassNotFoundException: AuthControl
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)

at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
basic: load: class AuthControl not found.
...
But if we use a direct path to the jar file, it's work fine without errors, example:
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {code:'AuthControl',
archive:'http://example.com/myapplet.jar', width:132, height:37};
var parameters = { scriptable:true, mode:'login' };
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>

The immediate issue I am having is using Selenium to click on the Login Button. The tag seems to be returning as a class and not an id.
<input class = "inline faux-button secondary" type ="submit" tabindex="3"
onclick="javascript:return Go()" value="Login" name="submit_button"></input>
I have been able to use just the findElement by id on other accounts I have, however you have to pay like £100 a year to stop being timed out every 10 seconds, so I get stuck after logging in.
iii.co.uk doesnt have a time out function so trying with this. How to access the input class above.

View Replies View RelatedOk say you have
public class MyClass {

When would the myObject be created? Before or after the constructor? And does this mean you can't pass
this into the parameters of that object?
I am not able to understand how we are able to create an object of static inner class defined inside an interface .
interface outer {

I have a doubt regarding to java.
Can we declare a class inside an interface?
Ans :yes
But what will be the situation?
I am not getting why it is required...........
What this interface inside that abstract class does. Looking for some examples to how can i use it ....
