In a standard Tomcat distribution, the default application is located in the ROOT directory /var/lib/tomcat5/webapps: From centos installation, this directory is empty. Please help us to bring up the apache-tomcat installation page. tomcat5.conf has the following settings CATALINA_HOME="/usr/share/tomcat5" JASPER_HOME="/usr/share/tomcat5" CATALINA_TMPDIR="/usr/share/tomcat5/temp" JAVA_ENDORSED_DIRS="/usr/share/tomcat5/common/endorsed" I see the following in /usr/share/tomcat5 after installtion.

Hello, I've got a Centos 5.4 box that is not rotating it's mail logs. I just found out about this, the file is considerably large.

Kernel Panic with wl.ko (Broadcom wireless driver) [CentOS 5.4]
by Martin Jungowski 14 Mar '10

14 Mar '10

Been experimenting with CentOS 5.4 some more. In order to get my wireless card to work (Broadcom BCM4311) I need Broadcom's wl.ko driver (http:// www.broadcom.com/support/802.11/linux_sta.php) It compiles fine after the necessary modification in typedef.h, loads and wireless works. However, as soon as I put some load on that interface (scp something from another machine, download something with Firefox, etc.) the machine kernel panics. I've tried the stock 2.6.18 kernel, the latest 2.6.18-164-11, and the latest patched 2.6.18-164-11-bug4139.4192.4196 (necessary to get my ALPS touchpad to work). I've tried two different versions of Broadcom's driver: 5.10.79.10 and 5.60.48.36. It doesn't kernel panic when I unload the wl kernel module, plug in a network cable and copy those files over ethernet. I downloaded the 2.6.27 kernel source and compiled my own kernel and it seems to work with that. However, for some weird reason, with any given self-compiled kernel (tried 2.6.18-8, 2.6.25 and 2.6.27) klaptop won't allow me to configure any standby/hibernation options because it doesn't recognize any of them. They do work perfectly fine though, I can pm- suspend the laptop from command-line. Any idea what else I could do? Either getting wl.ko to work with 2.6.18 (does somebody have a version older than 5.10.79.10 that they could email me?) or getting klaptop to realize that the laptop does indeed know how th suspend and hibernate with a non-CentOS-kernel would be fine.

mailman on CentOS with multiple virtual hosts
by David Mehler 13 Mar '10

13 Mar '10

Hello, This isn't exactly CentOS specific, but it does reference the CentOS way of doing things, so offlist replies might be better. I'm running a CentOS 5.4 server with postfix as MTA with virtual mailbox domains. I have set up a mailing list server lists.example1.com using apache virtual hosts and the mailman rpm. Now i want to add a second one call it lists.example2.com and am not sure how to pull this off. If anyone has a multiple virtual host setup i'd be interested. Thanks. Dave.
