You can register regular expression files with the application by adding a new context parameter for each regular expression file in the web.xml file (located inside your EARFILE/WARFILE/WEB-INF directory).
<context-param>
<param-name>scui-regex-file-<unique-identifier></param-name>
<param-value><file-path-inside-webapp>::<load order></param-value>
</context-param>
<context-param>
<param-name>scui-regex-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 regular expressions 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, the system considers it to be zero.
<context-param>

<param-name>scui-regx-file-fwk-2</param-name>
