Apache-Tomcat Servlet Mapping Issues

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

Re: Apache-Tomcat Servlet Mapping Issues

2005-06-22 Thread Hari Mailvaganam 
Hi David:

An alternate to using mod_JK is to proxy http (or https) request to
the Tomcat from Apache.

i.e:
ProxyPass /path http://localhost:port/path
ProxyPassReverse /path http://localhost/path

There are valid reasons for using mod_JK - above just an alternate
suggestion if you can do without mod_JK

regards,

Hari Mailvaganam

Hi,

As you test, can you load a servlet through apache httpd? Such as

http://www.xyz.com/testservlet

You should make a simple servlet that just has the doGet method to test.
