Servlet bug??

I have tested this problem on both tomcat-3.2.2 and tomcat-4.0-b3.
Here is a jsp that works just fine.

    Properties props = new Properties();
    InputStream is = null;
    try {
       is = getServletContext().getResourceAsStream("/WEB-INF/easMail.properties");
    } catch ( Exception ex ) {
	out.print("ResourceAsStream problem:" + ex.getMessage());
    }   
    try {
      props.load(is);
    } catch ( java.io.IOException e ) {
      out.print("Can't load the properties file");
    }
    for (Enumeration e = props.propertyNames(); e.hasMoreElements();) {
        String pn = (String)e.nextElement();
        out.print(pn + ": " + props.getProperty(pn) + "<br>");
    }

Here is its output

Test
mail.imap.socketFactory.class: javax.net.ssl.SSLSocketFactory
mail.transport.protocol: smtp
mail.imap.socketFactory.port: 993
mail.imap.socketFactory.fallback: false
mail.store.protocol: imap


Here is a snippet of code from my servlet.
line #
124  private void doTask() throws ServletException,IOException,
125				 EasMailException {
126	ssn = request.getSession(true);
127	String task = request.getParameter("task");
128	InputStream is = null;
129	try {
130            is = getServletContext().getResourceAsStream("/WEB-INF/easMail.Properties");
131	}
	catch (Exception ex) {
	    request.setAttribute("javax.servlet.jsp.jspException", ex);
	    svcxt.getRequestDispatcher("/Error.jsp").forward(request, response);
	}	    
	try {
	    props.load(is);
	}
	catch (Exception ex) {
	    throw  new ServletException( "can't find properties file: " + ex.getMessage());
	}

Here is the results from running the servlet.

Error Encountered.

java.lang.NullPointerException

java.lang.NullPointerException

What is wrong with this picture? Originally I had the code inside my
init() method, but moved it down in the main body of the class to see
if I was doing something wrong in the init() code.

Thanks
