[Geotools-gt2-users] RuntimeException: Unable to find function Length

[<Joh...@no...>]

Helllo All,

I have a very simple shapefile reading class based on the example
(http://docs.codehaus.org/display/GEOTDOC/04+How+to+Read+a+Shapefile). 

Everything works OK when executing w/ "mvn exec:java".  However, when I
bundle everything up into a executable jar using "mvn
assembly:assembly", I get a RuntimeException trying to use the generated
jar file.  I can't understand why there's a problem locating a function
"length" nor really why it's being called.  Any suggestions?

Thanks!
