_Normally_ the core java libraries are inserted onto the classpath for you,
hence
you may not always have to setup a classpath.

javax.* is not part of the core libraries, its name actually stands for 
'java extensions'. Over time some of these extensions, such as swing (javax.
swing)  
have made it into the normal distribution but others such as servlets have
not.

If you want to see what is or is not in the core distribution, go into the
libs
directory of the JVM installation of the JRE and open up rt.jar.. in there
you 
will find java.io, java.util etc etc.
