I'm having difficulty using apache.commons.cli with Java 1.4.2. I used
Eclipse to develop a simple program that uses apache.commons.cli. The
program works within the Eclipse IDE. However, when I export the program as
a Jar file and try to run the Jar from the command line (DOS or Unix). I get
a NoClassDefFoundErrorerror wrt the CommandLineParser. (In another program
that uses apache.commons.cli, running the jar file triggers the
NoClassDefFoundErrorwrt HelpFormatter. So, I think java punts on the first
class it sees containing a problem.)
I also extracted the apache.commons.cli source and built a Jar from it.
Strangely, I couldn't compile my program using my cli jar, instead on the
standard jar. When I extract classes from my cli jar, I noticed some of the
classes in apache.commons.cli are absent. I don't see anything peculiar in
the source.
I don't know how your application is packaged, but did you simply try to
put the commons-cli.jar file downloaded from
http://commons.apache.org/cli in your classpath ?
