Once the custom tool is built you can add it to Dekho using the Dekho AdminGUI. Click on the tools option and then the add button. Enter the tools name, tooltip, icon, and finally enter the URL of the custom tools SWF file in the parameters input box.
Note: For security reasons it will be easiest if you can place the custom tool SWF file in the root of the same domain as Dekho. Custom SWF files can be placed in the Dekho folder, however if Dekho is re-deployed any custom SWF files will be lost.
For a more detailed description of adding a new tool to Dekho see the Tools > add section of the Dekho Administrators Guide document.
