Hello everyone, I would like to know if it is possible to insert Java code in html, since I am trying to do a Java encryption program myself and put it inside the html.
I'm asking here why I have not found anywhere about whether it's possible and how to put it.
Before now yes .
Until recently my answer would be:
You need to use an applet for this because you can not insert the Java directly in HTML. Applets are getting more and more restricted and soon I think there will be no support for Java applets (they are very insecure).
But ... a project I met recently changed my answer to:
Yes is possible and using JavaScript!
This project is JavaPoly.js more information at link .
This is a library that allows you to have Java (JVM) support in browsers.
As an example you can do this in HTML:
<!-- Include the Polyfill -->
<script src="https://www.javapoly.com/javapoly.js"></script><!--WriteyourJavacode--><scripttype="text/java">
package com.demo;
import com.javapoly.dom.Window;
public class Greeter
{
public static void sayHello(String name)
{
Window.alert("Hello " + name + ", from Java!");
}
}
</script>
<!-- Invoke your Java code from Javascript -->
<script type="text/javascript">
com.demo.Greeter.sayHello("world");
</script>
Yes, this is Java in HTML!
Give up to import libraries:
<!-- Include the Polyfill -->
<script src="https://www.javapoly.com/javapoly.js"></script><!--IncludeyourfavoriteJavalibraries(jarfiles)--><scripttype="text/java" src="http://www.yourdomain.com/jimboxutilities.jar"></script><scripttype="text/java" src="http://www.yourdomain.com/guava.jar"></script><scripttype="text/java" src="http://www.yourdomain.com/apache-commons.jar"></script><!--Or,includeindividual.classfiles--><scripttype="text/java" src="http://www.yourdomain.com/com/yourpackage/Foo.class"></script><scripttype="text/java" src="http://www.yourdomain.com/com/yourpackage/Noise.class"></script><!--Orjustincludethesourcedirectly--><scripttype="text/java" src="http://www.yourdomain.com/com/yourpackage/Bar.java"></script><scripttype="text/java" src="http://www.yourdomain.com/com/yourpackage/Girls.java"></script>Note:NeverconfuseJavawithJavaScript link .
Note 2: I have never used it, it seems to me to be something recent and I do not know the support yet. But before we respond that it does not, I think it's good to know that there are people thinking about it.
Here's the result of Try It Yourself that's on the guys' website.
