There are four different ways one can deploy a webapp to Tomcat.
If $TOMCAT_HOME is the Tomcat top-level directory:

Copy the war file foo.war or exploded war directory to $TOMCAT_HOME/webapps
Create a context file context.xml in the webapp’s META-INF/ directory that contains a fragment that describes the webapp deployment
Add a <Context> element to the <Host> element in Tomcat’s server.xml that describes the webapp deployment, including docBase. docBase is a attribute that locates the war file or exploded war directory in the filesystem.
Create a context file foo.xml in $TOMCAT_HOME/conf/Catalina/localhost/foo.xml that contains a fragment that describes the webapp deployment, including docBase.

Sample $TOMCAT_HOME/conf/Catalina/localhost/foo.xml

If you are trying to debug Ruby code in RubyMine IDE, but are having difficulties such as, the IDE freezes after you try to step in, step over, or step next and are wondering if your configuration is wrong? It is not, if you happen to have installed the ruby-debug-ide19 gem from the command line (not from IDE), you need to patch the actual gem code to get things working nicely.

Open the following file with your favorite text editor (part of ruby-debug-ide19 gem)
```
$GEM_HOME/ruby-debug-ide19-0.4.12/lib/ruby-debug/command.rb
```
Add the following code at line ~120 (look below for full code location):
```
return "" if str == "$FILENAME"
```
