The directives in the namespace provide general configuration abilities like conditional configuration.

In general, we recommend avoiding the use of resin:if and resin:choose when possible, in order to keep configuration files manageable.

directive meaning
<resin:if> configures a block conditionally
resin:import imports a file into the current directive
resin:message output a log message during configuration
resin:set sets a variable or jndi-value
resin:choose selects one of a group of choices.

resin:import imports a configuration file into the current tag. The configuration file will match the current context, the a resin:import file in a <web-app> will be an XML file with a <web-app> tag.

tag meaning
fileset a set of files to import
path the file to import
optional if true, the target is optional

The web.xml and resin-web.xml files are loaded with a resin:import tag in the conf/app-default.xml file.


  <resin:import path="WEB-INF/web.xml" optional="true"/>
  <resin:import path="WEB-INF/resin-web.xml" optional="true"/>
