In address book, all user interface related source files (XML/XSL) are located under <uwc-deployed-path>/WEB-INF/ui/html/abs directory by default. To customize the user interface for a domain, follow these steps.
Create a directory with a domain name, (For example siroe.com) under <uwc-deployed-path>/WEB-INF/ui/html.
Copy all files from <uwc-deployed-path>/WEB-INF/ui/html/abs to<uwc-deployed-path>/WEB-INF/ui/html/<domain>.
Make the required changes in XSL files as explained in the chapter Chapter 7, Customizing General Features in Address Book.
Although all images are located under <uwc-deployed-path>/absimx by default, you may create a directory with a domain name (For example <uwc-deployed-path/absimx/siroe.com) under it and include the icons that are customizable under the newly created domain directory. Also ensure that the path reference to the newly created directory is updated in <uwc-deployed-path>/WEB-INF/ui/html/<domain> search-images.xsl and commonimages.xsl.
