Hello,
I have a class that it creates a new instance of
SAXParserFactory. When I execute main (), it works as well as I hope but if I
make a servlet and I try to execute it ( the same code), I obtain the next
error:
java.lang.SecurityException: sealing

Here you are the code of the
constructor.
Thanks for all.
public MIPGParseoXml(){
try {
factoria=SAXParserFactory.newInstance();
parseador = factoria.newSAXParser(); Vector_De_salida= new Vector(); }
catch (ParserConfigurationException s) { s.printStackTrace(); System.out.println("error ParserConfigurationException:"+s); } catch (SAXException s) { s.printStackTrace(); System.out.println("error ParserConfigurationException:"+s); } catch(Exception E) {
E.printStackTrace();
}
