If I have a folder that has multiple .jar files inside Is it possible to set the classpath with one declaration i.e. set classpath=c:\jar\*.*; instead of: set classpath=c:\jar\jar1.jar; c:\jar\jar2.jar;etc...
No, but with any Java 2 system, you can put any jars you like in the lib/ext directory of your JRE and they will automatically be picked up as if ther are in the classpath. This is how I load most of my jars.
