Im unable to display an image uploaded by a user on my local server (D:\fichiers)in a JSP,
using pure Jee (no spring), Tomcat 9, intelli-j idea.
I've tried everything i could find :
I tried to add :
<Context docBase="D:\fichiers" path="/images"/>
in context.xml in meta-inf, in server.xml in Tomcat installation conf folder, in server.xml in Tomcat/conf of the app, in catalina/localhost/root.xml, in catalina/localhost/context.xml.
But i still get an error 404, images not found.
Here is the server.xml file :
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Context docBase="D:\\fichiers" path="/images"/>
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b"/>
</Host>
and the jsp call :
<c:set var="chemin">/images/</c:set>
<c:forEach items="${spot.photos}" var="photo">
<img src="${chemin}${photo.nom}"/>
</c:forEach>
The only time it worked is when i checked on tomcat configuration
Deploy applications configured in Tomcat instance
But i had to remove it, cause Catalina was starting springframework on its own, and nothing worked properly after that.
Ok i found the answer, and though it's stupidly simple, i couldn't find a place where it was said.
In Tomcat configuration tab in Intelli-j :
Deployment Tab -> Add external Source -> Select the local Drive -> Put URL desired in Application Context, and that's it !
I am trying to add a vhost to my already running tomcat7 server.
I already have my default application running on tomcat successfully.
<Host name="mydefault.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
<Host name="myNewHostDomain.com"
appBase="wings_microx_cash_reports"
unpackWars="true" autoDeploy="true">
i have added the domain as well on dns (godaddy) and ping is running fine.
But when i check the logs in /usr/share/tomcat7/logs, i do not see anyinfo with respect to my new vhost
Also, when i send in a http request to my new host, i see the default host app is running
<Engine name="Catalina" defaultHost="mydefault.com">
Any pointers how i can check/rectify this?
sorry for false alarm
i had not closed the tag pproperly.
I want to deploy my app as root app so I renamed my war to ROOT.war. Default server.xml looks like -
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern="common" -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
I also need to serve some static content. So I added Context tag-
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<Context docBase="/home/athakur/Documents/UI" path="/" />
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern="common" -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
I want to serve static content from this path and apis from my ROOT.war. But as soon as I add context element ROOT.war is not expanding and getting deployed. When I remove the context path it does. Also UI is correctly rendered from the path post adding context tag. So don't want to change that behavior either.
Looks like we cannot do this. We cannot have two context with same path and different docBase under same host. So you cannot have -
<Context docBase="/home/athakur/Documents/UI" path="/" />
<Context docBase="ROOT" path="/" />
So I had to settle for
<Context docBase="/home/athakur/Documents/UI" path="/" />
<Context docBase="ROOT" path="/apis" />
If you however want to do it at root level only then you need to do it from inside your webapp.

I am trying to configure Tomcat7 serer.xml
the
<Host appBase="webapps/testweb" name="trythis.test.com" unpackWARs="true" autoDeploy="true">
<Context docBase="." path="" reloadable="false">
<Environment name="WEB_APP_PROPERTIES" type="java.lang.String" value="\\10.120.13.200\config"/>
</Context>
</Host>
Even though this config folder is accessible over the network my Tomcat can't access it:
I'm trying to create a tomcat cluster in order to replicate sessions.
my 2 tomcats are existing on two different machines,
All examples available showed clustering of 2 tomcats on same machine.
Where do i configure the ips of the tomcats in the configuration files?
(currently when i use the default configurations i get the error:"
Oct 30, 2013 10:21:03 AM org.apache.catalina.ha.session.DeltaManager getAllClusterSessions
INFO: Manager [localhost#/HATest]: skipping state transfer. No members active in cluster group."
Thanks!

For the default cluster configuration to work between multipl machines, multicast needs to be working. If the nodes can't see each then then the chances are that multicast is not enabled in one or more of the machnes / blocked at the network level / machines are on a different subnet.
In this case, you can use static membership to explicitly define the other machines in the cluster. See the Tomcat clustering docs for details.
Inside <Host></Host>, you need to do clustering.
Make use of the following example to modify your server.xml:
<Host name="site1.mydomain.net" debug="0" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Logger className="org.apache.catalina.logger.FileLogger" directory="logs" prefix="virtual_log1." suffix=".log" timestamp="true"/>

In this
host = system ip of the tomcat running on another machine and
port = receiver port of the tomcat running on another machine
In below receiver tag ...

address = is current machines ip address
Make these above changes in server.xml of tomcat running on current machine.
Similar changes need to be done in server.xml of tomcat running on other machine; only system ips and port will change.
Hope this will help you..
