Using a single JAR may have a very few advantages in particular cases, Java Web Start has some limitations but don't use a single JAR just to avoid using Java Web Start.

A JAR can be opened by the default archiver under Windows and Linux instead of being run. Moreover, some versions of web browsers (Firefox?) puts JARs into ZIP files but keep the same name which prevents them to work when double-clicking...

You can look at this and this. You can sign your JARs and generate your JNLP files in any IDE and/or with Ant too.
