Why can't processing find "Serial" when I build my library?

Reenforcements

Hello everyone,

I'm trying to make a library which depends on the core.jar and serial.jar from Processing. I couldn't figure out how to have multiple class paths, so I copied both the jars and their respective native libraries into a folder and set that as "classpath.local.location" in the build.properties. I also added the libraries as external jars to eclipse. For some reason, it can't find "Serial" as a symbol though. Why is this? Also, if anyone knows how I can reference both libraries directly from Processing instead of copying them that'd be great too!

Thanks you for sacrificing your precious time to help. Here's the log from an ant build. I copied the part in question below but I have the full log too.

Ant can't even find "println"? I don't understand why. I'm including both "import processing.core.*; import processing.serial.*;"

EDIT: Oops, okay, so println is actually a method of PApplet. This part makes sense now.

I've perused some Processing library sources and most of them can successfully import from "processing.core". It's located @ "core\library\" btW.

The other bundled libraries (dxf, io, net, pdf, serial, svg) are located @ "modes\java\libraries\".
Serial more precisely @ "\modes\java\libraries\serial\bin\processing\serial\Serial.class".

I'm also interested on how to build Processing libraries as well.
Hope some1 more experienced in it shows up here. 8-X
