Run a Java application in a web browser

Question

I am relatively new to Java and have a Java application consisting of a couple of packages and a number of classes. I want to be able to run this application in a web browse

Answer 1

I've written some kind of JVM which precompiles Java classes to native JavaScript. Here is an HelloWorld example which runs java programm in the browser:

it has also a WebGL demo which renders a 3D cube.

Answer 2

Java Web Start is a good technology for deploying Java applications over the web. You can start the application from a web page link, although the application runs outside of the web browser frame: Java Web Start Tutorial.

Java applets allow you to embed a Java application in a web page. It has some serious drawbacks for larger applications.

Servlets (and Java Server Pages) are appropriate technologies for server-side generation of web pages (and other web content) but these technologies won't help you to deploy an existing Swing-based Java application, unless you are prepared to replace the user interface.

Answer 3

If you want a really fancy web-browser based application written in java, then you should learn gwt.

Answer 4

See the section of the Java Tutorial on how to build and deploy applets.

Answer 5

The easiest way for you will be to use a servlet. What you need:

• Apache Tomcat (Or any other Servlet container)
• Knowledge of what a servlet is (basically a class that extends from servlet, like httpservlet)
