          ServletContext context = event.getServletContext();
          context.log("***ShowLifecycles - Created the servlet
context");

          ServletContext context = event.getServletContext();
          context.log("***ShowLifecycles - Destroyed the servlet
context");

  }

error information following:
org.xml.SAXparseException
the processing instruction target match "[xX][mM][lL]" is not allowed

how can I fix it?
