javax dot mail

[conrad]

If I have an application that utilizes javax.mail
then I imagine that I can do one of two things:
Include the jar file for javax.mail in a zip
file with my jar file and configure the classpath
appropriately to recognize both jar files.
Or, can a jar file include a jar file? In which
case, I just need to worry about a single
jar file and referencing it via classpath.

Thoughts?

Jar files in same dir and a Class-Path directive in the
manifest of your jar file is the standard solution for
the problem.

You might use an installer that puts the jar in the ext directory or
if your users are techies, just give them instructions on how to do
that as a prerequisite.
