Résumé de l'analyse des problèmes RSS

try{ 
   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 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++;  
           }
  }catch (Exception e) { 
   e.printStackTrace();
  }

Après avoir lutté toute la matinée, j'ai finalement réussi à le faire d'une manière différente.

La méthode dom4j ci-dessus fonctionne bien dans mon environnement local (windows+weblogic10+jdk1.6),
mettez-la sur le serveur (linux5.4 x64+weblogic10 +jdk1. 6), cette erreur est toujours signalée :
