Hi,
I'm working on a Struts/Tiles web app with Websphere 5.1.2 and Struts 1.2.4
I'm getting exceptions when trying to use the Validator framework.
After debugging, it almost seems as if the strut-config.xml is not being
properly digested.
The property maps of the Plug-Ins are always null.
Thus, the ValidatorPlugIn does not know that I've specified a "pathnames"
property.
Here's my struts-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts

This plugin initialize 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 plugin should 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
later case, it is still needed to declare one plugin per module.
The factory will be initialized with parameters found in the first
initialized plugin (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.
