Creating your first Jaxer application

Standalone Jaxer Server

To create a Jaxer application if you are using the standalone Jaxer server:

Use your favorite web editor to create the HTML, CSS, and JavaScript files for your project inside the new folder.

For help with building your first project, read through the code sample walkthroughs described on the Aptana samples page.
