You can register the rule XML files with the application by adding a new context parameter for each rule XML file in the web.xml file (located inside your EARFILE/WARFILE/WEB-INF directory).
<context-param>
<param-name>scui-validation-rules-file-<unique-identifier></param-name>
<param-value><file-path-inside-webapp>::<load order></param-value>
</context-param>
<context-param>
<param-name>scui-validation-rules-file-unique-identifier</param-name>
<param-value>fully-qualified-name-of-the-file::load order</param-value>
</context-param>
where load order defines the order in which the rules file must be loaded. File having the least load order will be read first. Multiple files can have same load order. If no load order is defined, system considers it as zero.
<context-param>
<param-name>scui-validation-rules-file-fwk-1</param-name>
<param-value>/WEB-INF/rules1.xml</param-value>
</context-param>
<context-param>
<param-name>scui-validation-rules-file-fwk-2</param-name>
<param-value>/WEB-INF/rules2.xml::1</param-value>
