System: Solaris SunOS 5.9
Apache: 2.0.52
Tomcat: 4.1.31
Mod JK: 1.2.6
The problem: Apache/mod_jk cannot resolve servlet URL mappings
When Tomcat is running stand-alone, it can resolve servlet mappings without
any problems; so that a page with this form definition:
<FORM name="login" method="POST" action="loginhandler">
correctly invokes the com.company.LoginHandler servlet (which suggests
there's nothing syntactically wrong with the <servlet> and
<servlet-mapping> entries in web.xml);
When Tomcat stand-alone is turned off and Apache is turned on, that same
page always throws a 404 error for "site/loginhandler"; these are the error
messages in mod_jk.log:
[Wed Jun 22 09:04:08 2005] [mod_jk.c (2313)]: mod_jk::jk_translate, check
alias_dir: /usr/apache/tomcat/webapps

What terribly simple configuration error have I made here?
These are the web.xml entries for this servlet:
<servlet>
<servlet-name>loginhandler</servlet-name>
<servlet-class>com.company.aiwosc.LoginHandler</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>loginhandler</servlet-name>
<url-pattern>/loginhandler</url-pattern>
</servlet-mapping>
This is the workers.properties file:
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=server.org
worker.ajp13.type=ajp13
This is the app section from mod_jk.conf:
