Using Maven overlay functionality, it is easy to deploy custom resources with the Resource Server.

Create a new Maven project with the resources you want to add or modify. At Yale we wanted to include custom xsl and css required by some of our portlets, and to modify jquery-ui-1.7.2-smoothness.css to fix a bug in the accordion menu styles for IE6. All other resources will be inherited from the Resource Server. We also wanted to override the log4j.properties, to ensure that logging from the resource server complied with our logging standards and that logs were saved in a standard location.
```
src
  main
    resources
      log4j.properties
src
  main
    webapp
      rs
        jqueryui
          1.7.2
            theme
              smoothness
                jquery-ui-1.7.2-smoothness.css
        yale
          <custom resources>
```

Create a pom for the project using the maven war plugin overlay functionality to merge the Resource Server 1.0.8 with your project. Note the exclusion of the .min.css file that is being modified in the custom resource project.

Add the custom resource server to your UPortal installation. At Yale, filtering for the framework, portlets, and any other web applications deployed with the portal, including log file location for a given environment (dev, test, prod), occurs during the uPortal build process. To include the custom resource server, do the following:

Add the ResourceServingWebapp to the uportal-portlets-overlay file structure

uportal-portlets-overlay
  ResourceServingWebapp
    pom.xml
