Hi all...
Thanx Dim for a step forward...
You're right... Apache redirected the request. :-))) I was looked only at
terminal (thinking that debug=9 is enough) - but in fact, just in mod_jk.log
there is two lines for every request to my servlet:
[jk_uri_worker_map.c (344)]: Into jk_uri_worker_map_t::map_uri_to_worker
[jk_uri_worker_map.c (434)]: jk_uri_worker_map_t::map_uri_to_worker, done withou
t a match
Here (you wrote similar advice "Re: Servlet configuration" to somebody else) I
looked to web.xml, which contains:
<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>Hello</servlet-class>
</servlet>
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>Hello</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
Maybe there is some redundancy or missing... but where? Because Hello.class is
in webapps/intranet/WEB-INF/classes (with all classes generated from jsps) and
web.xml is in WEB-INF... that's right I hope. URI is still the same:
host:port/intranet/servlet/hello
But I tried also Hello HelloServlet, all without servlet... etc. (Despair. :-))
Is it possible to let log mapping from URI to absolut path? With JSP this is
done, but with servlets I have no additional information from where it tries
load it. As fast I was done with JSP - I'm now stuck in this problem. I except
that solution is easy, but I can't see it.
Thanks for anything
