RE: Newbie Question about NoClassDefFoundError

Are you using a version of Java that's earlier than Java 1.4? If so,
you'll need to upgrade your version to at least 1.4 to be able to use
that class. The API documentation for the java.util.regex.Pattern class
says "Since: 1.4".

Subject: Newbie Question about NoClassDefFoundError

I am new at this (first time using Java routines from RPGLE) but I have
a problem that I have not been able to find in the archives.

I am attempting to demonstrate the feasibility of using Java routines to
create XLS spreadsheets to replace many of the reports that we deliver
to the users as CSV now. I got Scott Klement's "Excel Spreadsheets from
RPG" article with the source code (Thanks Scott). I am trying to compile
and run the XLCRTDEMO program. When I run it, it is attempting to define
a formula when the Java Machine throws this error
