上面这种dom4j方式，在我本机环境（windows+weblogic10+jdk1.6）下没问题，
放到服务器上（linux5.4 x64+weblogic10+jdk1.6）上，始终都报这个错：

在weblogic.xml加配置文件、加lib包等等都不起作用，换成这个就好了（依赖lib在我上传的资源中，完全免费）：
try { URL url = new URL(rss); // 读取Rss源 XmlReader reader = new XmlReader(url); System.out.println("Rss源的编码格式为：" + reader.getEncoding()); SyndFeedInput input = new SyndFeedInput(); SyndFeed feed = input.build(reader); // 得到SyndFeed对象，即得到Rss源里的所有信息 List entries = feed.getEntries(); // 得到Rss新闻中子项列表 int index =0; for (int i = 0; i < entries.size(); i++) { // 循环得到每个子项信息 if(index+1>rssTable.Rows.length){ break; } SyndEntry entry = (SyndEntry) entries.get(i); ci.adp.DataRow rssRow = rssTable.getDataRowByIndex(index); rssRow.setValue("TITLE", entry.getTitle()); rssRow.setValue("link", entry.getlink()); rssRow.setValue("PUBDATE", entry.getPublishedDate()); rssRow.setValue("SOURCE", entry.getAuthor()); index++; } } catch (Exception e) { e.printStackTrace(); }
org.dom4j.io.SAXReader saxReader = new org.dom4j.io.SAXReader();org.dom4j.document document = saxReader.read(rssUrl);org.dom4j.Element channel = (org.dom4j.Element) document.getRootElement().element("channel"); int index =0; for (java.util.Iterator i = channel.elementIterator("item"); i.hasNext();){ if(index+1>rssTable.Rows.length){ break; } org.dom4j.Element element = (org.dom4j.Element) i.next(); String title = element.elementText("title"); String link = element.elementText("link"); String pubDate = element.elementText("pubDate"); String source = element.elementText("source"); ci.adp.DataRow rssRow = rssTable.getDataRowByIndex(index); rssRow.setValue("TITLE", title); rssRow.setValue("link", link); rssRow.setValue("PUBDATE", pubDate); rssRow.setValue("SOURCE", source); index++; }以上就是解析rss问题的总结的详细内容，更多请关注考高分网其它相关文章！
