Running application keeps redirecting back to the Root application
I'm running an application under tomcat6. Also, if I go to the root of the tomcat server http://myserver:8080, I can see the tomcat home page displayed. I assume this is the ROOT in webapps. Regardless, then I attempt to hit the application by putting the name of the war on the end, http://myserver:8080/myapplication it redirects me back to the "root" server. I run several application in tomcat 7 and I do not see this behavior. Any idea what might be causing this? I do not see anything in the logs.

That means Tomcat will have to have access to mail.jar, typically by
placing a copy in Tomcat's /lib. Otherwise it can't load javax.mail.*.

Probably because the Resource could not be created. See above.

As another noted, this happens when you have two copies of mail.jar
available to the classloader tree, even when they are exact copies of
each other. Don't include a copy in your application if it is to be
provided by the container (which is required, if you want to use it
this way).

I use NetBeans with Maven, and in that context I would declare the
mail dependency to be provided. I don't know how to do
that in a native NetBeans project, but what you'd need to do is to
tell NetBeans that javax.mail is required to compile but must not be
included in the output WAR.
Or you can just manually remove mail.jar from the built application
before deployment. I have to do that with a community project that I
haven't yet had time to fully adapt to injection. Doing it
this way might be a good quick proof-of-concept for a nicer solution.
In summary: place mail.jar in Tomcat's /lib and NOT in your deployed
application.

Tomcat 7.0.41 shows v6 manager GUI
I have tomcat 7.0.41 running on multiple machines all running with jre1.7.0_80. I know they are identical installations because they are all extracted from the same tarball. On machines running Centos5, 5.4, 6.2 and 7, the manager GUI is the v7 look and feel. On one machine running Centos6.6, the manager GUI is the v6 look and feel. It doesn’t affect the functionality, but it is a difference that I can’t explain and that has me concerned. I’ve looked through the open bugs and the changeling on the Wiki and cannot find anything close. Has anyone else seen this? And, if so, what is the cause and is there a fix?

RequestDispatcher.forward between 2 virtual hosts defined in the same Tomcat container
Hi, I would like to know if we can do servlet forwarding between 2 different webapps deployed on 2 different virtual hosts configured in the same Tomcat container. So, I have configured 2 different virtual hosts in my Tomcat server.xml as follows: and put the root.xml file for default webapps to: $CATALINA_HOME/conf/Catalina/ directory. servlet2 is deployed as a different war in the 2nd virtual host. I notice that when I try to fetch the context of servlet2 from Servlet1 to do a forward from Servlet1 to Servlet2, the loaded context is null and so there is forwars. Please note that crossContext attribute is set to true in the context.xml for the 1st war. Also, noticed that in case I do not define any explicit virtual hosts and deploy both the wars in the default host i.e localhost, the forwarding works fine. Can somebody please let me know if servlet.forward works with virtual hosts. Any suggestions would be highly appreciated. Thanks Neha

This error indicates that you have mail.jar in two different classloaders.
Probably common loader and webapp loader. The one in tomcats lib folder -
common loader - is the right one.

I don't use netbeans, so I can't help you there. You could look for tutorials
about database drivers, they will probably be handled the same way.
