Hello. I'm trying to use some java classes that I've written in a processing program. I tried running the processing like normal java in Eclipse, but always got errors about missing libraries. I couldn't get processing to see my Java classes when working in the processing editor. So I ended up copying and pasting all the Java code into the processing program, but now I get an error:

/var/folders/mG/mGQVWF1NEWmgK0Oy5ChbME+++TI/-Tmp-/build5402827676892440067.tmp/JAVA_FILE.java is missing

Please, how can I do this? It should be really simple. Thank you for any help.
