jdbc

I'm having trouble getting the postgresql jdbc driver to work.  Here's my error:
java.sql.SQLException: No suitable driver       at java.sql.DriverManager.getConnection(DriverManager.java, Compiled
Code)      at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code)       at
DBBean.<init>(DBBean.java,Compiled Code)       at DBBean.main(DBBean.java, Compiled Code)
 

I'm running Linux with the 1.2.2 jdk.
I'm running pgsql 7.0.2.

CLASSPATH=/usr/lib/pgsql/jdbc7.0-1.2.jar:.

Any help would be appreciated.
