        /js/
        /WEB-INF/
            /src/ (not created by default)
            liferay-display.xml
            liferay-plugin-package.properties
            liferay-portlet.xml
            portlet.xml
            web.xml
        icon.png
        view.jsp

Answer 1

• Icon.png is default image icon displayed in your portlet, At top left corner just before Portlet title. If you want to use your image replace default icon.png with yours keeping the name same.

OR As Olaf Kock suggested

• Update your image path / name in liferay-portlet.xml as the location to change/configure icon.png

<icon>/newicon.png</icon>

Answer 2

Better option is to create a new theme with pluginsSDK, (copy the classic theme for starting) and then replace the portal favicon in the new theme folder with new one.

Alternatively, add the following code in portal-ext.properties file:

theme.shortcut.icon=your_new_icon.ico
