Subject Servlets / Includes - not working
Date Fri, 26 Sep 2003 21:00:48 GMT
Hello, 

Current working environment:
RedHat 7.3
jakarta-tomcat-4.1.24
apache_1.3.27
j2sdk1.4.1_02

I setup tomcat to use multiply workers so each apache server would have its
own worker and catalina base. This setup works for serving jsp pages and the
examples page works (except Include and JSP-Servlet-JSP). Also non of the
servlets under /examples/servlets/ work. 

When I attempt to load JSP-Servlet-JSP I get a 404 error:
	The requested resource (/examples/servlet/servletToJsp) is not
available.

I get the same error when I attempt to load
<url>/examples/servlet/HelloWorldExample
	The requested resource (/examples/servlet/HelloWorldExample) is not
available.

The Include example <url>/examples/jsp/include/include.jsp! atleast gives me
an exception:
	org.apache.jasper.JasperException: /jsp/include/include.jsp(10,0)
Invalid buffer size


I'm using the default web.xml file that came with tomcat so I won't include
that. But I'll include  server.xml and the important parts of my httpd.conf
file. I also attached the mod_jk.log entry for each failure. 

Hopefully someone can tell me what part of my config I messed up or how to
gets servlets and includes working. 

Please let me know if you need any additional information.  

Thanks so much for your help, 
Keith. 

There are some comments in the config as I tried different things to get it
working.
