Groovy not reading jar files in .groovy/lib - jdbc

Question

I'm having a problem with jar files and groovy. For a few specific examples I'm trying to connect to a postgresql database and when using
sql = Sql.newInstance("jdbc:postgresql://localhost", "user", "pass", "org.postgresql.Driver")
I get a ClassNotFound exception for org.postgresql.Driver. I have the postgresql jar in my ${user.home}/.groovy/lib, and the line to load from there in the groovy-starter.conf is not commented out. I'm also having a similar problem with a dbunit.jar file.
If I try to manually add the classpath using groovy -cp I'm getting an error that says
Caught: java.io.UnsupportedEncodingException: p
Any ideas?

According to the CLI Help - http://groovy.codehaus.org/Groovy+CLI:
$groovy -help
usage: groovy
-a,--autosplit <splitPattern> automatically split current line
(defaults to '\s')
-c,--encoding <charset> specify the encoding of the files
-e <script> specify a command line script
-h,--help usage information
-i <extension> modify files in place
-l <port> listen on a port and process inbound lines
-n process files line by line
-p process files line by line and print result
-v,--version display the Groovy and JVM versions
groovy -cp will tell groovy to load characterset p which does not exist.
Your attempt to use ${user.home}/.groovy/lib should have worked assuming you used the correct path for ${user.home}. If you add info on your OS we might see if you got it right or not.
As a WA - just export the CLASSPATH environment variable to wherever the jars are located.
Windows: set CLASSPATH=c:\temp\postgresql.jar;c:\temp\dbunit.jar ...
Unix/Linux (KSH): export CLASSPATH=${HOME}/temp/postgresql.jar:${TEMP}/temp/dbunit.jar ...
