Protein Alignment Tool

This is a problem I ran into when adding activation.jar and mail.jar (both from Sun) to my .jnlp file. It turns out that these JAR files are already signed by Sun. All JAR files within a JNLP file must be signed by the same certificate - the way around it is to have multiple JNLP files and use the extension keyword.
