The Management Console user interface (
https://localhost:9443/carbon) of a Carbon product consists of two layers:
- UI inherited from WSO2 Carbon platform contains the templates, styles (css files), and images that are stored in the core Carbon UI bundle stored in
<version-number>is the version of the Carbon kernel that the product is built on. This bundle is responsible for the overall look and feel of the entire Carbon platform.
- UI unique to each product contains all the styles and images that override the ones in core Carbon platform. This file is in
<version-number>is the version of the product.
The following topics explain how to download a Carbon product and customize its user interface.
Setting up the development environment
To download and set up the product environment for editing, take the following steps.
- Download your product.
- Extract the ZIP file into a separate folder in your hard drive.
- Go to the
<PRODUCT_HOME>/repository/components/plugins/directory to find the required JAR files:
- 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.
Customizing the user interface
Customizing the product interface involves changing the layout/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.
Changing the layout
The layout of the Carbon framework is built using a tiles JSP tag library. The use of tiles allows us to break the presentation of the layout into small JSP snippets that perform a specific function. For example,
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. That is, the header part in the
template.jsp file is replaced with the
<tiles:insertAttribute name="header"/> tag, which refers to the
header.jsp file. The
template.jsp file as well as the JSP files corresponding to the tiles are located in the
Therefore, changing the layout of your product primarily involves changing the
template.jsp page (main layout page) and the JSP files of the relevant JSP tiles.
Ensure that you do not change or remove the ID attributes on the
Changing the styles on the Carbon framework
global.css file, which determines the styles of the Carbon framework, is located in the
org.wso2.carbon.ui_<version-name>.jar/web/admin/css/ directory. You can edit this file as per your requirement. Alternatively, you can apply a completely new stylesheet to your framework instead of the default
To apply a new style sheet to the carbon framework:
- Copy your new CSS file to this same location.
- Open the
template.jspfile located in the
global.csswith the new style sheet by pointing the
String globalCSSattribute to the new stylesheet file.
Changing the product specific styles and images
The styles and images unique to your product are located in the
org.wso2.<product-name>.styles_<version-number>.jar folder. To modify product specific styles and images, take the following steps.
- Copy the necessary images to the
org.wso2.<product-name>.styles_<version-number>.jar/web/styles/images/directory. For example, if you want to change the product banner, add the new image file to this directory.
- Open the
main.cssfile located in the
To specify a new product banner, change the
org.wso2.<product-name>.styles_<version-name>.jar/web/styles/css/main.cssfile as follows:
Note that 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.<product-name>.styles_<version-name>.jar/web/styles/css/ directory to ensure that the other UI elements of your product aligns with the product logo.
Starting 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.
- Compress the contents of the
org.wso2.<product-name>.styles_<product-version>.jarfolders into separate ZIP files.
- Change the name of the ZIP file to
- Copy these two new JAR files to the
repository/components/plugins/directory in your product installation.
- Start the server.
