Re: Compile error accessing method in an adjacent package

I'm an experienced Java programmer but I've been away from Java for a
few years and need a bit of a memory assist. Also, I don't remember
all of the terminology so forgive me if I use the wrong word
occasionally: I'll try to be clear in what I mean so that you
understand what I'm asking.
I have two packages in the same Eclipse (Galileo) project:
com.foo.old and com.foo.new. The "new" package does the same thing as
the "old" package but has a couple of new classes that have some new
functionality. All of the existing classes in the "old" project are
completely unchanged. The "new" package contains only the classes
containing the new functionality and a new version of the "driver"
program from the old package. The "driver" program basically just
instantiates each of the other classes in turn with statements like
this, where Alpha is the class called by the driver program and
writeBlah() is its primary method, and x and y are parameters passed
from the driver program (x is a String and y is an Object):
new Alpha().writeBlah(x, y);

In the "old" package, the driver program finds classes Alpha, Beta
and all of their peers in its own package. The old version of the
driver program works perfectly.

My problem is in accessing the classes in the old package from the
"new" version of the driver in the "new" package.

I did CTRL-SHIFT-O in Eclipse so that it would find Alpha and its
peers in the "old" package and the statement to import com.foo.old
appeared without difficulty. However, now I get a compile error. The
method name, writeBlah, is underlined in red and the message says
"the method writeBlah(String, Object) in the type Alpha is not
applicable for the arguments (String, Object).".
