Sitemaps for Java

Tutorial

Using Sitemaps for Java is pretty strait forward, as shown in the example below. Sitemaps for Java currently supports two strategies in Sitemap-creation:

Sitemaps
Also known as sequential sitemaps, where URLs are written in the order they are added.
ChangeFrequencySitemaps
Groups URLs by the frequency at which they update. This is a good idea if you have huge amounts of URLs and prefer that Google only download Sitemaps with URLs that change reguarly.

Sitemaps can be created as compressed Sitemaps with the setCompressed() to true, and if validation of the result is required set setValidationIncluded() to true.


// ...
try {
  // Create Sitemaps for example.com
  Sitemaps sitemaps = new Sitemaps(
       new java.net.URL("http://www.example.com"),
             new File("C:/homedir/example.com/"));

  // Compress the sitemaps
  sitemaps.setCompressed(false);

  // Without validation
  sitemaps.setValidationIncluded(false);

  // Now add URLs
  URL url1 = new URL(
      new java.net.URL("http://www.example.com/index.html"),
      new Date(System.currentTimeMillis()),
      ChangeFrequency.ALWAYS, 1.0);


  sitemaps.addURL(url1);

  URL url2 = new URL(
      new java.net.URL("http://www.example.com/faq.html"),
      new Date(System.currentTimeMillis()),
      ChangeFrequency.HOURLY, 0.75);  

  sitemaps.addURL(url2);

  // Close sitemaps and write - also writes Sitemap Index
  sitemaps.close();
} catch (Exception e) {
  e.printStackTrace();
}
//..

The Javadocs give an overview of the API.
