Resource XML
The Resource XML is where Aura starts to get really cool. Any file that ends with Resource.xml will be processed by Aura as a configuration data file. Root node for this file must be resources and nested between resources are WAS configuration items. . Here is a basic example:
<resources>
<Cell name=”${{CellName}}” >
<JDBCProvider name="MyProvider">
</JDBCProvider>
</Cell>
</resources>
Between these resources tag, you can set Cell with name being a token. Other attribute values like database name can tokenised and replaced with tokens as required. Syntax of tokens is ${{CellName}}. Tokens within the curly brackets will be replaces with values specified in the environment properties file.
