That is up to the specification you put into the manifest file for your applet's JAR. Have a read around the spec docs with the JDK for details on this, but it's relatively simple to do. As an example, here is a manifest entry that we use in Xj3D for the Java3d rendering component: Class-Path: xj3d-norender.jar xj3d-core.jar xj3d-parser.jar xj3d-sav.jar Class-Path: xj3d-net.jar uri.jar j3d-org.jar Extension-List: java3d java3d-Extension-Name: javax.media.j3d java3d-Specification-Version: 1.2 java3d-Implementation-Version: 1.2.1.04 java3d-Implementation-Vendor-Id: com.sun java3d-Implementation-Title: Java3D Core Runtime Environment java3d-Implementation-URL: http://java.sun.com/products/autodl/java3d/prefer_ogl/java3d-$(os.name)$.jar Extension-Name: xj3d Specification-Vendor: Web3d Consortium Specification-Version: 3.0 Implementation-Vendor-Id: com.yumetech Implementation-Vendor: Yumetech, Inc Implementation-Version: 2.0 -- Justin Couch http://www.vlc.com.au/~justin/ Java Architect & Bit Twiddler http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
