You can use third-party libraries: such as HtmlUnit

It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use.

Example:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class JavaScriptProgram
{
    private WebClient webClient;
    private HtmlPage currentPage;

    public JavaScriptProgram()
    {
        webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_8);
        webClient.setThrowExceptionOnScriptError(false);
        webClient.setJavaScriptEnabled(true);
    }

    public void visitPage(String url)
    {
        try
        {
            currentPage = (HtmlPage) webClient.getPage(url);
        }
        catch(Exception e)
        {
            // Cannot get the page
        }
    }

    public void executeJavaScript(String code)
    {
        currentPage.executeJavaScript(code);
    }

    public static void main(String[] args)
    {
        JavaScriptProgram p = new JavaScriptProgram();
        p.visitPage("http://www.stackoverflow.com");
        p.executeJavaScript("document.write('Hello World!');");
    }
}

If you want browser capability within your Swing app, you could check Lobo, it supports Javascript too.

Swing components doesn't support Javascript codes natively. If you really need integrate Javascript and Java, you can try Rhino. But remember: it's javascript language only, you cannot use browser's API.
