Tomcat allows you to create multiple server instances for the same installation. The installation directory is identified as CATALINA_HOME , the instance directory is identified as CATALINA_BASE . Here are the steps: Create a base directory for the new instance, for example: /home/nogeek/tomcat1 . Create the subdirectories: mkdir -p /home/nogeek/tomcat/{bin,conf,logs,temp,w...

Linux services startup order in general: kernel runs /sbin/init /sbin/init reads /etc/inittab and runs script defined by this line: si::sysinit:/etc/init.d/rcS switches to runlevel defined by id:3:initdefault: which causes /etc/init.d/rc to be called with the current run level. /etc/init.d/rc calls the scripts under the /etc/rc <current_run_level> .d directory (symbolic links to actual scripts under /etc/init.d/ ) in this order: The KILL scripts first (scripts with name starting with K, i.e., rc?.d/Knn name ): "script_name stop" then, the START scripts (scripts with name starting with S, i.e., rc?.d/Snn name ): "script_name start" Within each group (KILL or START), run scripts from lower priority number (i.e., the nn in the symlink name) to higher priority number. The Upstart init daemon does not use /etc/inittab . Instead, it...

This is a simple web application with a single servlet and a single JSP page. It is intended to be a test bed for JSTL tags. You may want to store all syntax, rules, and exceptions in your head, but in my opinion nothing beats a simple test program that allows you play with it all you want. So here it is (build with Maven ). Prerequisites: Maven: http://maven.apache.org/ . You don't need any prior knowledge of Maven, but you need to install the binary. JBoss: http://jboss.org/jbossas/downloads/ , or Tomcat: http://tomcat.apache.org/ if you don't run the SQL tests. You need to know how to deploy a web application (shh! Don't tell your boss it's just copying a file to the deployment folder). Steps: The directory...

If you want to add security to your wireless network, you almost never want to use WEP . WPA is an improved encryption algorithm that avoids many of the WEP vulnerabilities. However, FC4 (Fedora Core) doesn't support WPA out of the box. I have to install wpa_supplicant in order to access my wireless AP with WPA encryption. Since my Airlink wireless card only shipped with Windows drivers, I also needed ndiswrapper to make it work under Linux. This is my experience setting up wpa_supplicant with ndiswrapper. 1. Download wpa_supplicant 0.5.8 from http://hostap.epitest.fi/wpa_supplicant/ . Extract files to a working directory. 2. Create a .config file that contains: CONFIG_DRIVER_NDISWRAPPER=y CONFIG_CTRL_IFACE=y The first line initially read CONFIG_DRIVER_WEXT=y following the ndiswrapper documentation, but that didn't work for me. 3....
