Customize the Management Console

The user interface of the Management Console ( https://localhost:9443/carbon) of a Carbon product consists of two layers:

  1. UI inherited from WSO2 Carbon platform

    The bundle, org.wso2.carbon.ui_<version-number>.jar located in <IS_HOME>/repository/components/ plugins/, contains the templates and styles (css files) for the Management Console. The <version-number> is the version of the Carbon Kernel that WSO2 Identity Server is built on. This bundle is responsible for the overall look and feel of the entire Carbon platform.

  2. Unique UI of each product

    Each Carbon product (that is built on Carbon kernel) has another style bundle, org.wso2.identity.styles_<version-number>.jar located in <IS_HOME>/repository/components/plugins/. This contains all the styles and images that override the ones in core Carbon platform. The <version-number> is the version of the product.

The following sections will guide you through the customization process.

Set up the development environment

To download and set up the product environment for editing, follow the steps given below.

  1. Download the latest version of WSO2 Identity Server.
  2. Extract the ZIP file into a separate folder in your hard drive.
  3. Go to the <IS_HOME>/repository/components/plugins/ directory to find the required JAR files:
    • org.wso2.carbon.ui_<version-number>.jar
    • org.wso2.identity.styles_<version-number>.jar
  4. Copy the JAR files to a separate location on your hard drive. Since the JAR files are zipped, you must unzip them to make them editable.

You can now customize the look and feel of your product by modifying the contents of the JAR files as described in the next section.

Customize the user interface

Customizing the product interface involves changing the layout (or design) of the Carbon framework as well as changing the styles and images specific to the product. The following topics explain how some of the main changes to the product interface can be done.

Change the layout

The layout of the Carbon framework is built using a tiles JSP tag library. These tiles allow us to break the presentation of the layout into small JSP snippets that perform a specific function.

For example, header.jsp and footer.jsp are the tiles corresponding to the header and footer in the layout.

The template.jsp file controls the main layout page of the Carbon framework, which holds all the tiles together. The template.jsp file as well as the JSP files corresponding to the tiles are located in the org.wso2.carbon.ui_<version-name>..jar/web/admin/layout/ directory.

Therefore, changing the layout of your product primarily involves changing the template.jsp page (main layout page) and other .jsp files of the JSP tiles.


Do not change or remove the ID attributes on the .jsp files.

Change the styles on the Carbon framework

The global.css file located in the org.wso2.carbon.ui_<version-name>.jar/web/admin/css/ directory determines the styles of the Carbon framework. You can edit this file as per your own requirement. Alternatively, you can apply a completely new stylesheet to your framework instead of the default global.cssstylesheet.

Apply a new style sheet to the carbon framework

  1. Copy your new CSS file to this same location.
  2. Open the template.jsp file located in the org.wso2.carbon.ui_<version_name>.jar /web/admin/layout/ directory, which contains the main layout of the page and the default JavaScript libraries.
  3. Replace global.css with the new style sheet by pointing the String globalCSS attribute to the new stylesheet.

    //Customization of UI theming per tenant
    String tenantDomain = null;
    String globalCSS = "";
    String mainCSS = "";

Change the product specific styles and images

The styles and images unique to WSO2 Identity Server Management Console are located in the org.wso2.identity.styles_<version_number>.jar file. Follow the steps below to modify product specific styles and images.

  1. Copy the necessary images to the org.wso2.identity.styles_<version-number>.jar/web/styles/images/ directory.

    For example, if you want to change the product banner, add the new image file to the above directory.

  2. Open the main.css file located in the org.wso2.identity.styles_<version-name>.jar/web/styles/css/ directory.

  3. To specify a new product banner, change the background-image attribute of org.wso2.identity.styles_<version-name>.jar/web/styles/css/main.css file as follows:

    /* ---------------- header styles ------------------ */
    div#header-div {
        background-image: url(;


The size of the images you use will affect the overall UI of your product.

For example, if the height of the product logo image exceeds 28 pixels, you must adjust the main.css file in the org.wso2.identity.styles_<version-name>.jar/web/styles/css/ directory to ensure that the other UI elements of your product aligns with the product logo.

Start the server

In the preceding steps, you have done the changes to the product interface after copying the JAR files to a separate location on your hard drive. Therefore, before you start your production server, these files must be correctly copied back to your production environment as explained below.

  1. Compress the contents of the org.wso2.carbon.ui_<version-number>.jar and org.wso2.identity.styles_<product-version>.jar folders into separate ZIP files.
  2. Change the name of the ZIP file to org.wso2.carbon.ui_<version-number>.jar and org.wso2.identity.styles_<version-number>.jar respectively.
  3. Copy two new JAR files to the <IS_HOME>/repository/components/plugins/ directory in your product installation.
  4. Start the server.
