This may seem long but I wanted to include anything
I thought was relevant.

  CATALINA_HOME=/usr/local/jakarta/jakarta-tomcat-4.0.2-b2
  JAVA_HOME=/usr/java/jdk1.3.1_02

I added a new <Host> entry to server.xml for my new website.
This is the only change I made to the stock server.xml.

>   <Host name="192.168.0.52" debug="0" appBase="webapps" unpackWARs="true">
>     <Realm className="org.apache.catalina.realm.MemoryRealm" />
>
>     <Valve className="org.apache.catalina.valves.AccessLogValve"
>              directory="logs"  prefix="192.168.0.52_access_log."
suffix=".txt"
>              pattern="common"/>
>
>     <Logger className="org.apache.catalina.logger.FileLogger"
>                prefix="192.168.0.52_log." suffix=".txt" timestamp="true"/>
>
>     <Context path="/manager" docBase="manager" debug="0" privileged="true"/>
>
>     <Context path="" docBase="NewWebsite" debug="0" reloadable="true">
>       <Logger className="org.apache.catalina.logger.FileLogger"
>                  prefix="NewWebsite_log." suffix=".txt" timestamp="true"/>
>     </Context>
>   </Host>

This works great.  When I point my browser at http://192.168.0.52:8080/
I get my home page and the JSP/servlet stuff works as expected.

Like so many other, the next step is to set up the
Warp connector so that I can front Tomcat with Apache.

I changed the stock httpd.conf (RedHat 7.2 i386) by adding a
new <VirtualHost> section to correspond to NewWebsite above.
I installed mod_webapp.so from the downloaded webapp-module-1.0.2-tc402
archive.

>   NameVirtualHost 192.168.0.52
>
>   LoadModule webapp_module modules/mod_webapp.so
>   WebAppConnection warpConnection warp 192.168.0.52:8008
>   WebAppDeploy examples warpConnection /examples/
>
>   <VirtualHost 192.168.0.52>
>   ServerName 192.168.0.52
>   WebAppDeploy NewWebsite warpConnection /
>   </VirtualHost>

The address 192.168.0.52 will eventually become a properly
DNS-registered name www.NewWebsite.com (names and ip
addresses may have been changed to protect the guilty).

The intention is to have any request for http://192.168.0.52/ be
redirected by mod_webapp to the NewWebsite Tomcat context.
But that is not what happens.  Instead, the browser sits as if
it is loading something that never comes and there are no
messages in any of the apache & tomcat log files on the server.
Not even an access log entry.

On startup of httpd I get the following message in the httpd
error log.

So I should probably first address the [warn] about EAPI.

I've got jakarta-tomcat-connectors-4.0.2-b2-src.tar.gz  and
jakarta-tomcat-connectors-4.0.2-b2.patch from
tomcat4-4.0.2-b2.1.src.rpm
(though I can't remember where I got that src rpm?).

I've unpacked it and am about to dive in but I thought I'd check
with the group here to see if I'm going along the right track.

Should the above configuration work (once I get rid of the EAPI problem
with my freshly compiled mod_webapp.so)?

One of the strange things (to me) is
the setup I've shown here is the actual production machine that I'm
trying to prepare.
My development/test machine OS/Apache is very similar (RedHat 7.1 instead)
and a very similar setup works fine.


Thanks
Kevin.
