No, the information is not present in the source file.

There are a number of workarounds:

 o APT (introduced in 1.5, part of javac in 1.6) gives access to
parameter names (it works on source). For instance see:
http://weblogs.java.net/blog/emcmanus/archive/2006/06/intermxbean_ref.html

 o Run some form of parser on your source to store the information in a
convenient format. You could use a complete parser (like APT), or add
tags within comments to the source.

 o Compile with variable name debugging enabled, and use ASM (or
similar) to read the class file.

 o Compile with line number and file name debugging. Read the
information for the constructors with either ASM or arrange for an
exception to be thrown/created (and parse the stack trace). Use a regex
to extract the information from the source (which will need to be easy
to regex). See: http://www.jroller.com/page/cpurdy?entry=yaul_trace
