Subject RE: serving servlets from jar files
Date Fri, 24 May 2002 14:07:36 GMT
When I change the web.xml setting to
<servlet>
<servlet-name>DateServlet</servlet-name>
<servlet-class>com.test.date.DateServlet</servlet-class>
 </servlet>

I get:
2002-05-24 09:02:06
StandardWrapper[/cediac01:org.apache.catalina.INVOKER.DateServlet]: Marki
ng servlet org.apache.catalina.INVOKER.DateServlet as unavailable
2002-05-24 09:02:06 invoker: Cannot allocate servlet instance for path
/cediac01/servlet/Date
Servlet
javax.servlet.ServletException: Wrapper cannot find servlet class
DateServlet or a class it d
epends on
[...]
----- Root Cause -----
java.lang.ClassNotFoundException: DateServlet
[...]


It doesn't show that it is even looking in my jar file now.
