Setting multiple jars in java classpath

Is there a way to include all the jar files within a directory in the classpath?

Java error: Only a type can be imported. XYZ resolves to a package

I get the error: "Only a type can be imported. XYZ resolves to a package."

How do I add logging.properties to the classpath of an Eclipse project?

I'm using Eclipse 3.7.1 and my code isn't seeing my logging.properties file. (I thought it would see it automatically because it is in the standard place within the JRE but that is apparently wrong). I've been told I need to add this file to the root of the classpath but I'm not sure how to do that.
