jdbc driver and jar problem

[Liz]

Is there something special about jdbc drivers
and jar files? My app runs fine using MySQL.
The MySQL jar file is in my classpath. When
I put the app into a jar file, I keep getting
class not defined; it can't find the driver.
Even if I put the MySQL jar file in the current
directory it can't find it.

try

java -cp \path\to\mysql.jar;\path\to\my.jar package.of.MainClass
or
java -cp /path/to/mysql.jar:/path/to/my.jar package.of.MainClass

or write a Class-Path attribute into your jar's manifest.

Note that if you start your application using the -jar command line
option then all the class path options are ignore and only those found
in the manifest file of the jar is used.
