OK, I
upgraded to 4.0.2 and here is the
updated error:
java.lang.NoSuchMethodError:

I have found
this function in the file
core-3.2.3.v_686_R32x.jar in the drools/lib directory for 4.2.
One of the
things that has happened
recently is that I have upgraded from 3.2 to 3.3.1. I thought this
might be
part of the problem, but I looked at the core jar for 3.3.1 and it has
the same
method.
The thing
that puzzles me is that
I'm not including the core file in my distribution, but if that's
the problem, why am I not getting a ClassNotFoundException?
Thanks.

NoSuchMethodError
I am running 4.01 and I
started get this exception on a new
piece of code:

It is blowing up on this
line of code:
builder.addPackageFromDrl(
new StringReader(drl)
);
Which is the drl created
from the spreadsheet compiler on
the decision table.
This rules class has been
tested thoroughly under junit. It
wasn't until I deployed the library into my webapp that this issue
turned
up.
Does anyone have any idea
what I should be doing next?
