NullPointer building a document,
March 2, 2010 at 4:25 AM

while(urlList.hasNext())
{
URL url = urlList.next();
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(url);

processElements(doc.getRootElement());

}


the code above sometimes works sometimes doesn´t. when it doesn´t works a NullPointerExeption is thrown in "Document doc = builder.build(url);" line. The curious is that my urlList has 10 identicals urls
