Subject RE: Servlet Context Listener problem...
Date Tue, 15 Jul 2003 01:30:47 GMT
Listeners must be declared before any servlets in web.xml. I'd check that
first.

Subject: Servlet Context Listener problem...


Hi:

I implemented ServletContextListener in my class. I then wrote the xml  
in the web.xml file and started tomcat. The error tomcat threw tells me  
that it did not recognize the listener and listener-class elements ?? i  
have them declared in the web.xml as:

<web-app>
	
	<!-- ServletContextListener -->
	<listener>
		<listener-class>
	
com.wavesinmotion.cw.classes.jsphelpers.CourseWizardContextListener
		</listener-class>
	</listener>
</web-app>

Any ideas where I am going wrong ?
Thanks.

Tomcat threw this error below:
