In the Taverna Workbench 2.x, if you click on the Import new services button in the Service Panel, a drop-down for different types of services will appear. Select the one that corresponds to the new service and paste the Web address (URL) of the new service in the pop-up window. For example, to add the DDBJ Blast service, you would type the WSDL address (http://xml.nig.ac.jp/wsdl/Blast.wsdl) into the Import new services -> WSDL service box.
In Taverna 1.7.x Workbench, if you right-click on the Available Processors node in the processors tree, a drop-down for different types of processors will appear. Select the one that corresponds to the new processor and paste the Web address (URL) of the new service in the pop-up window. For example, to add the DDBJ Blast service, you would type the WSDL address (http://xml.nig.ac.jp/wsdl/Blast.wsdl) into the Available processors -> Add new WSDL scavanger box.
