java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver

Hi eee:
I get the below error:

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
        at java.net.URLClassLoader.findClass(URLClassLoader.java:241)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:516)

        at java.lang.Class.forName(Class.java:142)
        at ExportFromMSSQL.main(ExportFromMSSQL.java:15)

The steps I have taken to set up my env are as folliws:
1. Add the javac and the sqljdbc.jar to my environment as follows:
PATH=/home/asmith:/home/asmith/perl/:/usr/ucb:$HOME/bin:/usr/bin/X11:/
sbin:/usr/java131/jre/bin:/usr/java131/bin:/myhome/asmith/JDBC/sqljdbc_2.0/enu/sqljdbc.jar:.

Where things reside:
1. My javac resides in usr/java131/bin
2. Downloaded and installed the MS driver (http://www.microsoft.com/downloads/details.aspx?FamilyId=F914793A-6FB4-475F-9537-B8FCB776BEFD&displaylang=en) into JDBC subdir. Now the dir structure looks like below
/myhome/asmith/JDBC/sqljdbc_2.0/enu > ls -l
total 1720
