There are no separate trial and licensed builds of JAR archives for MindFusion components. When you purchase a license, you can find the license key for this component listed on the Keys & Downloads page at MindFusion's customer portal. Pass this license key to the DiagramView.setLicenseKey method to disable the component's evaluation mode and stop displaying trial messages. setLicenseKey is a static method and you need to call it just once from application's initialization code.
