Classpath reading in Linux

http://stackoverflow.com – $ $CLASSPATH $ .profile $CLASSPATH > bash: :/usr/java/connectors/mysql-connector-java-5.1.23-bin.jar: No such file or directory $ /usr/java/connectors/mysql-connector-java-5.1.23-bin.jar > no main manifest attribute, in /usr/java/connectors/mysql-connector-java-5.1.23-bin.jar What I'm having trouble understanding is, when I run it from $CLASSPATH (to see if it has been set) why it's not being detected. Shouldn't it be the same if I type it in? I'm getting two different results. the connector is 0777 with owner root:root. (HowTos)
