Another "java.lang.NoSuchMethodError" question

I've seen a lot of posts about this, but I still can't make heads or tails
of it. I have a couple of programs that started throwing these exceptions
lately. I "don't think anything has changed" with these programs or this
class, but I did have a friend walk me through re-compiling a different
class a few weeks ago. I have a feeling it's more than a coincidence.


Here's what I am seeing:

exception "java.lang.NoSuchMethodError: writeDetailRows" when calling

ava.lang.String;Ljava.lan" in class "Reports.LastTwoST".
Recovery . . . : Contact the person responsible for program maintenance
to
determine the cause of the problem.
Technical description . . . . . . . . : If the exception indicates that
the
Java class was not found, ensure the class for the method is in the
class
path. If the exception indicates that the Java method was not found,
check
the method name and signature. If the signature is not correct, change
the
RPG prototype for the method, or change the Java method, so that the
return
type and parameter types match. You can determine the signatures for all
the
methods in class XYZ using command QSH CMD('javap -s XYZ').
