I have a tomcat server running perfectly fine apart from writing the access logs.
In Server.xml, the access log is defines like below:
<Server port="xxxx" shutdown="SHUTDOWN">
<GlobalNamingResources>
----
</GlobalNamingResources>
<Service name="Catalina">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="access." suffix=".log" pattern="common" resolveHosts="false"/>
<Connector --- />
<Connector --- />
<Executor --- />
<Engine name="Catalina" defaultHost="localhost">
<Realm ---/>
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"></Host>
</Engine>
</Service>
I can see that accesslog valve is defined under service tag and not inside of Engine, host or Context as per common implementation. Can this be the reason behind the server not writing access logs
Official documentation suggesting supporting this: https://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Access_Logs
Got this comment from server.xml :
A "Service" is a collection of one or more "Connectors" that share
a single "Container" Note: A "Service" is not itself a "Container",
so you may not define subcomponents such as "Valves" at this level.

I would like to run two tomcat services on two ports (8080,8181) with different codeBases, but sharing the same database resource. When I do this, I get "javax.naming.NameNotFoundException: Name [comp/env/jdbc/mydb] is not bound in this Context. Unable to find [comp]." when it tries to initialize the second Service.
My Services look like this in the server.xml:
...
<GlobalNamingResources>
<Resource auth="Container" name="jdbc/mydb" url="jdbc:db2://myserver:50000/mydb" username="xxx" password="xxx" .... />
</GlobalNamingResources>
...
<Service name="Catalina8080">
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
....
<Host name="localhost" appBase="webapps8080" unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" .... />
</Host>
</Engine>
</Service>
<Service name="Catalina8181">
<Connector port="8181" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8444" />
<Engine name="Catalina" defaultHost="localhost">
....
<Host name="localhost" appBase="webapps8181" unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" .... />
</Host>
</Engine>
</Service>
My server level context file looks like :
<Context>
...
<ResourceLink name="jdbc/mydb" global="jdbc/mydb" type="javax.sql.DataSource" />
</Context>
I've tried adding and removing the Resource links at the application level context file, but nothing seems to change the outcome. Any thoughts are greatly appreciated.
You should change the name of your <Engine> in the second service: there can be only one naming context for each combination of engine name, host name and context name.
In your case the combination (Catalina, localhost, your application name) probably appears twice, hence you should be able to find an entry like this:
SEVERE [main] naming.namingContextCreationFailed
in the logs and JNDI doesn't work in the second context.
I have a trouble with configure of Apache and Tomcat. My purpose is to get ability to adress to tui.org/servlet, when tui.org is my virtual host configured on local machine and /servlet/ is url-pattern which is defined at web.xml. But instead the servelet I get 404 Not Found by Tomcat but I can to adress to my server by tui.org/tui.org/servlet - it works. Structure of files on my server is the following:
Root: /var/www/tui.org
-------->/WEB-INF/classes/a
-------->/WEB-INF/classes/a/MainServlet.class
-------->/WEB-INF/web.xml
-------->/index.html
How can I achieve this behaviour?

<servlet-mapping>
<servlet-name>mainServlet</servlet-name>
<url-pattern>/servlet</url-pattern>

Configuration of tui.org (tui.org.conf at /etc/apache2/sites-available:
<VirtualHost *:80>
ServerName tui.org
DocumentRoot /var/www/tui.org
<Directory /var/www/tui.org>
AllowOverride All
Require all granted
</Directory>
JkMount /servlet* ajp13_worker
</VirtualHost>
I use Apache2, tomcat9 and Ubuntu 18.04.
Thank you in advance!
P.S. Sorry for my english.
There are several issues here:
You must not serve the web application directory with Apache - e.g. you're declaring DocumentRoot /var/www/tui.org for Apache and <Host appBase="/var/www/"> for Tomcat.
e.g but not limited to: The servlet spec specifically disallows to serve the directory WEB-INF to ever be served to a client, and you're explicitly bypassing this limitation.
An application deployed in a Host's appBase is always deployed under that name (unless specified differently in a context.xml file). The only other exception to that rule is if a directory is called ROOT - in that case, it's deployed without a name, thus omitting the tui.org that follows your server name.
but this is secondary to the issue of serving the whole webapp through Apache httpd. Fix that one first.
One way to fix your biggest problem is to omit the DocumentRoot directive in Apache and rather serve everything from Tomcat: JkMount * ajp13_worker.
For solving problem with adressing by tui.org/servlet I had to add <Context> directive to server.xml:
<Context path="" docBase="/var/www/tui.org/"/>
and change appBase from /var/www/ to /var/www/tui.org/.
And for fix problem with access to WEB-INF (thanks to #OlafKock) I had to add next to tui.org.conf:
<Directory /var/www/tui.org>
AllowOverride All
Deny from all
</Directory>
To be precise I need to get pictures from an external directory say: C:/MWDB.
I found this link: How to config Tomcat to serve images from an external folder outside webapps? which I wanna follow up with the part where you need to add a directory in your server.xml context tag.
So Basically Based on the way it says I came with that it should be like:
<Context docBase="C:/MWDB" path="/images" reloadable="true" source="org.eclipse.jst.jee.server:Duck"/> (request: www.example.com/images/image.png) with this way while restaring the server it pops me an error saying
The server at localhost has encountered a problem
Which then I did this: <Context docBase="C:/MWDB" path="/images"/> And This I can't even access my index.html file

I'm using Java 8, Apache Tomcat v9.0
Okay I figured out my problem.
Basically What I didn't know is that you could have multiple <context> at the same time.
So When I had something like:
<Context docBase="C:/MWDB" path="/images"/>
I could Server from only MWDB directory and not my internal Project and that is why I couldn't access my index.html file. So For to server from both directory Simply you can do:
<Context docBase="C:/MWDB" path="/images" reloadable="true" source="org.eclipse.jst.jee.server:Duck"/>
<Context docBase="C:/MWDB" path="/images"/>
Works Perfectly so far :)
Every application deployed on my Tomcat returns status code 404 on every request I make. I've tried several projects, helloworlds or skeletons and every project behaves the same as others:
Some of the projects I've used:
https://github.com/mwarman/skeleton-ws-spring-boot
https://spring.io/guides/gs/rest-service/ (I can run it with mvn spring-boot:run but it's not working as deployed to Tomcat)
https://github.com/shagstrom/spring-mvc-hibernate-skeleton
I'm using the newest Tomcat8 (8.0.27), Oracle JDK 8. I've also tried Tomcat7 with OpenJDK 7.
Used Tomcats are running on MAC and Debian.
I've build apps via mvn and via Intellij Idea.
Tomcats are clean, no configs are changed (except adding manager-gui user).
Since I've tried many different projects, I don't believe the problem is in the code. Is it in Tomcat's config? How can I get it to work?

If you installed tomcat successfully, you may have seen tomcat main page from browser http://localhost:8080/ URL. (Otherwise, you need to check tomcat installation first.)
I guess you may have built jar by fallowing above sites that you mentioned.
I am wondering whether you applied the jar into your tomcat or not because you mentioned same result from any other projects.
You need to apply jar or war into your tomcat in order to apply java program.
Here are links that I wish they might be helpful to you.
Packaging war : How to make war file in Eclipse
Tomcat - war file deployment : https://www.youtube.com/watch?v=9X9DA8oVodk
If tomcat returns 404 response, you have to check those points:
check if your deploy was correct
check if war bootstrap and its ServletContext initialization has no errors
check if the resource your invoking was successfully exposed.
To test these issues you have to expose:
static resource test
web service resource test
in this way you can exclude the pitfalls you can meet during application deploy

I am trying to get Apache to forward requests to the examples that come with Tomcat. I did it once on another machine a few months ago, but on this new server I am stump.
Tomcat is running fine, localhost:8080 loads the default homepage and localhost:8080/examples/ displays the example page. But when I drop the 8080 and use port 80 on the apache server, it simply gives me a 404.
What is really bugging me is the lack of any log info on why. I am using the stock httpd-jk.conf with this added:
JkMount /examples/* worker1
Then this is my workers.properties:
worker.list=jk-status
worker.jk-status.type=status
worker.jk-status.read_only=true
worker.list=jk-manager
worker.jk-manager.type=status
worker.list=worker1
worker.worker1.reference=worker.template
worker.worker1.host=localhost
worker.worker1.port=8009
worker.worker1.activation=A
worker.template.type=ajp13
worker.template.socket_connect_timeout=5000
worker.template.socket_keepalive=true
worker.template.ping_mode=A
worker.template.ping_timeout=10000
worker.template.connection_pool_minsize=0
worker.template.connection_pool_timeout=600
worker.template.reply_timeout=300000
worker.template.recovery_options=3

Answering with a checklist;
Are you certain port 80 is served by the Apache you expect - are your "404" responses showing in the access logs of that Apache instance
are you certain your mod_jk module is being loaded (see Apache logs, or use one of the Apache status page views to verify); if the module was not loaded, the JK configuration section would be silently ignored
are you certain your workers.properties is being found (Still, see Apache logs; you might also wish to raise the JkLogLevel in httpd.conf to trace for the time being; also, make sure you know where your JkLogFile is located)
Then about the SSL issue; mod_jk and mod_proxy_ajp should both work. If you just want basic "server-side SSL", and are not working with client certificates, then everything will be handled by your Apache httpd. If, on the other hand, you'll be doing client authentication using SSL client certificates, then I think there's another SO posting rather relevant to that use case.
