And it is the same problem that I did not add the line for the preload servlet in the
web.xml. So I don't know is that any error on the line that I add to the web.xml.
Since the applcation is running on the Jrun with no problem and I only change the
environment from Jrun to tomcat. And tomcat and Jrun seems to be the same to be the
servlet engine. So I think there is the problem of the setting. But I still do not
where is the problem come from.
Thanks for your help.
b) Do you get the same error when you start the servlet manually (by
connecting with a browser)?

Subject: Preload Servlet in Tomcat
Hello,
I am just develop a application in Jrun and I am trying to
run it on tomcat 3.2.1 (Both for web server and servlet
engine) on win2k. And I want to preload a servlet when the
tomcat start.
I add some line in the file TOMCAT_HOME/conf/web.xml
like that
servlet
servlet-name
ContentServletNT
/servlet-name
servlet-class
com.i2.iba.test.ContentServletNT
/servlet-class
load-on-startup
1
/load-on-startup
/servlet
But after I restart the server, it seems not work. It display
a error with the same as without this line. Is there any
problem with this few line?
And I am also cannot login the admin page of the tomcat. What
is the username and password for the tomcat admin page?
Thanks for your help.
Regards,
Patrick Lee
