Tomcat + Ubuntu Juju = HA/clustered and integrated Tomcat in Seconds
Hi Tomcat Expert, You probably know Ubuntu from the Ubuntu desktop or phone. You might know that we are the number 1 operating system in the cloud and the number 1 OpenStack distribution. What you might not know is that one of our latest open source products, Jujuhttp://juju.ubuntu.comcan instantly deploy, integrate and scale any server software on any cloud or server. An expert makes a charmhttps://juju.ubuntu.com/docs/charms.html one time and anybody in the world can instantly deploy it via juju deploy charmname or via our GUI http://jujucharms.com We are trying to give anybody in the world an instant high-available/clustered tomcat stack based on a blueprint design. If you want to understand what we mean with instant just go to comingsoon.jujucharms.com and drag and drop the tomcatHAstack.yaml file on the canvas. You will see how tomcat, apache, haproxy, memcached, terracotta, mysql, postgres and mongo all get installed in multiple instances and mostly all get instantly integrated. This is exactly our problem, we are almost where we want to be with creating instant Tomcat clusters and having tomcat come pre-integrated with lots of third-party software. However we must admit that we are not a Java fortress. We are not an expert on how to make the tomcat clustering work on any cloud. We build three versions of tomcat but non is really the top quality that we would have hoped for: tomcat charmhttp://comingsoon.jujucharms.com/sidebar/search/~robert-ayres/precise/tomcat-3/?text=tomcat tomcat7 charmhttp://comingsoon.jujucharms.com/sidebar/search/oneiric/tomcat7-0/?text=tomcat tomcat6 charmhttp://comingsoon.jujucharms.com/sidebar/search/precise/tomcat6-1/?text=tomcat We now got a request from a non-profit group, that is creating open source software to help poor countries better manage their health records, to use our tomcat charm to install their software in high-availability clusters. We could really use some help from the tomcat community and ideally have the tomcat community take over the ownership of the tomcat charm hence anybody can instantly have blueprint solutions that come pre-integrated and scale on the click of a button. Can you please help us? We can give you remote training on how to charm and you can find more info on creating charms here https://juju.ubuntu.com/docs/authors-charm-writing.html.

Tomcat getting stopped when idle
Hi, We are facing some weird issue in our Tomcat environment. After starting the Tomcat process on one of our Solaris server, process is automatically getting shutdown after 2-3 minutes if no activity is done through Application deployed in Tomcat. I have observed similar issue in one of following mailing thread where as user has asked to install a Listener and print a stacktrace when the stop event happens. I need to know how to install such Listener. http://www.mail-archive.com/users@tomcat.apache.org/msg84717.html Server version: Apache Tomcat/6.0.16 Server built: Jan 28 2008 11:35:29 Server number: 6.0.16.0 OS Name:SunOS OS Version: 5.10 Architecture: sparc JVM Version:1.6.0_51-b11 JVM Vendor: Sun Microsystems Inc.

com.amazonaws.services.dynamodb.sessionmanager.DynamoDBSessionManager
Hi, when I use the com.amazonaws.services.dynamodb.sessionmanager.DynamoDBSessionManager I get classloader issues when a session gets deserialized and my session contains classes which are not available to the shared loader. My question: Is this a bug in com.amazonaws.services.dynamodb.sessionmanager.DynamoDBSessionManager? I do not want to put these classes into the shared loader because they belong only to a special webapp. Thank you. P.S.

Re: Multi-URL Access 1 Webapp
Starting over since i can not seem to get this to work with tomcat or apache.
So what i have now that IS somewhat working is:
#This rewrites https://share.anydomain.tld to our mail server
RewriteEngine On
RewriteCond %{HTTP_HOST} ^share\.
RewriteCond %{HTTPS} on
RewriteRule ^/(.*) https://192.168.123.3:8443/share/$1 [P]
This DOES get me over to the tomcat side but gives a 404. Notice the status
line:
HTTP Status 404 - /share/share/page/
Tomcat seems to be adding an extra /share. User need to access the web app with
https://share.anydomain.tld which will land on apache and apache will get it to
tomcat. The web app is accessible from http://ip:8080/share or
https://ip:8443/share. How do i stop tomcat from adding the extra share?

RE: Multi-URL Access 1 Webapp
mod_rewrite is what's adding the extra /share/
RewriteRule ^/(.*) https://192.168.123.3:8443/share/$1 [P]
should be something like either:
RewriteRule ^/(.*) https://192.168.123.3:8443/$1 [P]
or:
RewriteRule ^/share/(.*) https://192.168.123.3:8443/share/$1 [P]
..depending on whether you want to proxy all URL's to Tomcat, or just the
/share ones..

Configuring Embedded Tomcat for SSL
Tomcat version: 7.0.47
OS: Windows 7 (x64)
JDK: 1.7
I am attempting to start an embedded instance of Tomcat, which is
configured for SSL only, on port 443. The code I am using is as follows:
*public* *static* *void* *main*(String[] args)
*throws*UnknownHostException, LifecycleException, ServletException {
Tomcat tomcat = *new* Tomcat();
tomcat.setBaseDir(D:\\Temp);
tomcat.addWebapp(/sslapp, D:\\);
Connector connector = *new* Connector();
connector.setPort(443);
connector.setScheme(https);
connector.setSecure(*true*);
connector.setAttribute(address, 127.0.0.1);
connector.setAttribute(SSLEnabled, *true*);
connector.setAttribute(bindOnInit, *true*);
connector.setAttribute(keystoreFile,
...\\EngineInstance.keystore);
connector.setAttribute(keystorePass, password);
connector.setAttribute(clientAuth, false);
connector.setAttribute(sslProtocol, TLS);
connector.setAttribute(keyAlias, test);
connector.setAttribute(keyPass, password);
tomcat.setConnector(connector);
tomcat.init();
tomcat.start();
tomcat.getServer().await();
}
When I run the above, I receive the following output:
Nov 01, 2013 10:08:07 AM org.apache.catalina.core.StandardService
startInternal
INFO: Starting service Tomcat
Nov 01, 2013 10:08:07 AM org.apache.catalina.core.StandardEngine
startInternal
INFO: Starting Servlet Engine: Apache Tomcat/7.0.47
Nov 01, 2013 10:08:07 AM org.apache.catalina.startup.ContextConfig
getDefaultWebXmlFragment
INFO: No global web.xml found
It does not look like the connector I created is actually being started.
When I try browsing to the above port using Chrome/IE all it does not
connect.
I thought I was following the correct process base don information I
located on Google, however, it would appear I am still doing something
incorrect.
I have confirmed the existence of the private key in the keystore (using
Keystore Explorer), so all that is fine.
Please, any help would be greatly appreciated.
Cheers,
Matthew
