Hi,
If following code is valid
Category cat = Category.getInstance(NameOfTheServlet.class.getName());
then, could you please give me an example of how to use Log4J with
servlets?
I need to use XML file as configuration file which should be parsed
thru' servlet
and necessary logging should be done.
Currently I've used the following code (inside doPost method):
---------------
static Category cat =
Category.getInstance(assign4Servlet.class.getName());
try
{
URL url =
getServletConfig().getServletContext().getResource("/sample1.xml");
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setValidating(true);
DocumentBuilder builder =
factory.newDocumentBuilder();
Document doc =
builder.parse(url.toExternalForm());
DOMConfigurator.configure(doc.getDocumentElement());
--------------
-------- some servlet code --------
--------------
cat.info("Inside doPost method of the servlet");
cat.debug("Inside doPost method of the
servlet");
}
catch(ParserConfigurationException eP)
{
}
catch(SAXException eS)
{
}
--------------------
file sample1.xml is in the same directory as the servlet class file.
But there is no log being generated.
What could be the problem?
Thanks & regards,
Amit

Hello Scott,
Categoty.getInstance takes a string or a class. Assuming that the
MyFooBar class is in the ch.qos package. The following a strictly
equivalent:
Category x = Category.getInstance("ch.qos.MyFooBar");
Category x = Category.getInstance(MyFooBar.class.getName());
Category x = Category.getInstance(MyFooBar.class);
