How do I use multiple JAR files signed by different certificates?

The JNLP 1.0 specification requires all JAR files used in a JNLP file to be signed by the same certificate. This restriction avoids requiring the user to accept multiple certificates from the same source, and enables Java Web Start to know if the user has accepted all certificates used for an application. However, Java Web Start can use multiple JAR files signed by different certificates, by using the component extension mechanism and multiple JNLP files. The only requirement is that the JAR files contain code from different packages.
