Configuration

Each module takes its own set of configuration files. Within a module, each Calyxo component is configured through individual configuration files.

Generally, all Calyxo configuration files are in XML format and share the ability to

• import another configuration file: the imported configuration is merged into the importing configuration.

  <base:import file="../calyxo-control-config-shared.xml"/>
  

  This feature greatly supports sharing of common configuration parts between modules.
• define, initialize and store Java objects as local variables or as module (or application) scope attributes:

  <base:set var="content" value="/WEB-INF/content"/>
  

  or even

  <base:set var="mybean" scope="module">
    <base:object class="...MyBean">
      <base:property name="foo" value="bar"/>
    </base:object>
  </base:set>
  

  Simple, but very useful...
• use JSP EL expressions in so called dynamic attributes to reference local variables and attributes in module- or application scope.

  <foo value="${mybean}"/>
  

• declare functions to be used in dynamic attributes: you can provide you own function libraries.

  <base:functions prefix="bar" class="...MyFunctions"/>
