Introduction
Oct 14, 2018
Jaunt 1.5.1 release

Test drive Jaunt today and leave feedback in the forum to help shape the next release!
Jaunt is a Java library for web-scraping, web-automation and JSON querying. The library provides a fast, ultra-light browser that is "headless" (ie has no GUI). The browser provides web-scraping functionality, access to the DOM, and control over each HTTP Request/Response, but does not support Javascript*. Jaunt enables your Java programs to:
  • peform web-scraping and JSON data extraction
  • work with forms and tables
  • control/process individual HTTP Requests/Responses
  • interface with REST APIs or web-apps (JSON, HTML, XHTML, or XML).
*Now you can automate Chrome, Firefox, Safari, Internet Explorer, etc,
with full Javacript support, using Jauntium.
Code example: Google scraper - search for 'butterflies'
UserAgent userAgent = new UserAgent();         //create new userAgent (headless browser)
userAgent.visit("http://google.com");          //visit google
userAgent.doc.apply("butterflies").submit();   //apply form input and submit
    
Elements links = userAgent.doc.findEvery("<h3>").findEvery("<a>");  //find search result links
for(Element link : links) System.out.println(link.getAt("href"));   //print results
