JavaCrawler - Version 1.0 JavaCrawler is a java tool for crawling the web. You select your search term, the starting page, and the depth. JavaCrawler will crawl from one page to another searching for your term. Wherever it finds it, JavaCrawler returns that page. This program is sold for only $22. However, to run it, you need the java runtime to be installed on your system. The java runtime can be downloaded for free from the java official web site. Note that JavaCrawler runs on all available operating systems (not just Windows).
