Apache-Tomcat mod_jk servlet mapping issue

Posted: Nov 6, 2002 9:50 AM

I am using an Apache Tomcat integration with MOD_JK.. Attached is the server.xml file and httpd.conf file. I at least want to get the HelloWorldExample servlet to work..but can not even get that..Please anyone help. My jsps are working fine. I have my physical web application seperate from the tomcat install..thus the virutal host mapping. My document root is: /home/httpd/cordimarian-as
Under that I have copied the /examples folder from the tomcat install but I can not get the HelloWorldExample to run.
the url I'm entering in is http://www.cordimarian-as.org/examples/servlet/HelloWorldExample
but i get the HTTP Status 404 - /examples/servlet/HelloWorldExample is not available.....

***can anyone tell me what I'm missing or what is out of WHACK?
Any info you can provide would be wonderful!!!
Thanks,
-T

--server.xml

<Host name="www.cordimarian-as.org" debug="0" appBase="/home/httpd/cordimarian-as" unpackWARs="true">
<Alias>www.cordimarian-as.org</Alias>
<Ali as>cordimarian-as.org</Alias>
<Alias>208.32.141.154</Alias>
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="cordimarian-as_access_log."
suffix=".txt" pattern="common" />
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="cordimarian-as1_log." suffix=".txt"
timestamp="true" />

<Context path="" docBase="/home/httpd/cordimarian-as"
debug="0" />

<Context path="/home/httpd/cordimarian-as" docBase="/home/httpd/cordimarian-as" debug="0" reloadable="true">

</Context>

<Context path="/examples" docBase="examples" debug="0"reloadable="true" crossContext="true"></Context>
</Host>

httpd.conf file is as follows:--

[...]

# Purpose: Integrate Tomcat v4.1.12 [jsp support] into Apache

JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
JkMount /examples/servlet/* ajp13
JkMount /*/servlet/ ajp13

# Purpose: change root directory for apache and tomcat server
(.jsp support)
# to the same, to avoid conflicts and problems such as loading
an image file

[...]

Few things...
1. Can you run http://www.cordimarian-as.org:8080/examples/servlet/HelloWorldExample ? i.e, Does your servlet work without Apache. If not, that needs to be resolved first.

2. DocumentRoot is just where Apache serves static content from. Not very much related to Tomcat.

3. Edit your workers.properties file to make entries like this:


worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=aj p13

4. In your server.xml look for AjpConnectionHandler and see that you have the same port set as above (8009)

If this seems overwhelming, spend some time on a HOW-TO here: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/index.html
