您的主要问题是，您正在查找的信息并不存在于您使用的URL上，而是位于

Your main problem is that the information you're looking for, does not exist at the URL you're using, but at http://www.portal.pwr.wroc.pl/box_main_page_news,241.dhtml?limit=10.
You should first get that page, and than use this (it's a combination of Hovercraft and Andrei volgon's answers) -

String url = "http://www.portal.pwr.wroc.pl/box_main_page_news,241.dhtml?limit=10";
String baseURL = "http://www.portal.pwr.wroc.pl/";
Document doc = Jsoup.connect(url).get();
Elements links = doc.select(".title_1 > a");
for (Element link : links) {
    System.out.println("Title - " + link.text());
    System.out.println(baseURL + link.attr("href"));
}
