This is a blank Struts configuration file with an example

Tiles and the Struts Validatorare configured using the factory defaults
and are ready-to-use.
NOTE: If you have a generator tool to create the corresponding Java classes
for you, you could include the details in the "form-bean" declarations.
Otherwise, you would only define the "form-bean" element itself, with the

This plugininitialize Tiles definition factory. This later can takes some
parameters explained here after. The plugin first read parameters from
web.xml, thenoverload them with parameters defined here. All parameters
are optional.
The pluginshould be declared in each struts-config file.
- definitions-config: (optional)
Specify configuration file names. There can be several comma
separated file names (default: ?? )
- moduleAware: (optional - struts1.1)
Specify if the Tiles definition factory is module aware. If true
(default), there will be one factory for each Struts module.
If false, there will be one common factory for all module. In this
latercase, it is still needed to declare one plugin per module.
The factory will be initialized with parameters found in the first
initializedplugin (generally the one associated with the default
module).
true : One factory per module. (default)
false : one single shared factory for all modules
- definitions-parser-validate: (optional)
Specify if xml parser should validate the Tiles configuration file.
true : validate. DTD should be specified in file header (default)
false : no validation
Paths found in Tiles definitions are relative to the main context.
