I have an active/passive nodes with Tomcat using heartbeat. When I shutdown the active node, Tomcat on passive node starts. This is a piece of the starting trace:
INFO: Initializing Coyote HTTP/1.1 on http-8080 May 22, 2014
7:37:43 PM org.apache.catalina.startup.Catalina load INFO:

app name VentusProxy May 22, 2014 7:37:59 PM
org.apache.catalina.mbeans.JmxRemoteLifecycleListener createServer
It takes 15 seconds to initialize JAAS, that means 15 seconds more without service.
I don't use JAAS at all in my application, so I'd like to disable it or, at least, try to reduce this 15 seconds.
Can anybody tell me if this is possible and how?

I'm working through an EJB tutorial where my client program invokes a method via remote stateless EJB to add a book. Upon exit the client retrieves and prints all the books from the EJB (I know it's not a good idea to store data in a list within a stateless EJB). All of this works fine, except the initial RMI also returns the following exception (I've included the full output from the client test as well).
Client output:

So everything with the client, other than the exception, appears to work correctly. I suspect this issue has something to do with the zero'd out node addresses, but I'm not certain. The client properties file is below (in case that configuration is incorrect).

can you help me please
Check whether you have created any static connection objects. Static object tend to live in the server heap even when the application is stopped.
I seem to be having the same problem that everyone has with Struts2 and getting it up and running, driving me mad :#
Having manually written the files from the Hello_World_Struts2_Ant project and run into build path issues, I decided I should just download the project to see it up and running.....
For some reason the only page I can access from this project is index.jsp, when i try to click on the link for hello.action or visit hello.action through the address bar, it gives me a tomcat 404. (I am running tomcat 7).
I would usually concede that it is my own idiocy that has led me here, but the fact that the project download from the struts site isn't working is just plain annoying.....
I'm not great with tomcat error logs, but I can't see anything that can help me with this issue.
Any help would be greatly appreciated.
To save me loading this page with all code that I have, I've got the code that is distributed here: http://code.google.com/p/struts2-examples/downloads/detail?name=Hello_World_Struts_2_Ant_2_3_1_2.zip&can=2&q=

After a reading the above posts I deleted my Tomcat installation and started again from scratch that way, it seemed that Tomcat had been the problem as it worked straight away for me after reinstalling tomcat.
It had perhaps been me deploying things as root.war that caused the tomcat issue.
The "same problem" thing was that I had done a bit of search before posting this and found a lot of folk having issues with getting struts up and running, perhaps a poor phrase to describe the issue on my part.
Thanks for the help though! Defainately going to look into Maven as a lot of folk seem to recommend it, although the copying to WEB-INF/lib and configuring build path works for now :)

I had the same problem with Tomcat 6 and Struts2 2.1.8 webapp (maven 3.0.3 + eclipse keepler + JDK 1.6.0_22). I'm new in struts2+tomcat developing and I'm not used to solve this kind of problems.
After having made some changes on my code (and don't use svn nor git...), and after start using a mvn tomcat:redeploy task (witch confused me) I had this same behavior, and don't know what were causing to fail the deployment (the project keeps compiling ok).
The error seems so confusing and zero descriptive to me, and I've read many related posts. I've tryed to update the struts2 version, cause I've read that this kind of problems seems solved in struts2 2.3.3 (was using 2.1.8).
https://issues.apache.org/jira/browse/WW-3768
I dont't know why I was just reading catalina log:

The answer was very close, in localhost-date.log!
That point me to a bad declared action in struts.xml, so simple to solve and so descriptive, but so dificult to figure out just reading catalina log.
