[java] Compiling.

Hi, I''m having some problems compiling a java file. It''s neccessary for me to compile this file via a .jar file. In my note it says to type javac - classpath file1.jar file2.java This is for UNIX btw but I''m doing this from the command prompt in XP. Anyway this doesnt work so I''m wondering how I do this. I''ve also tried to compile it using JCreator LE but again it is dependant on the .jar file and I cant work out how to compile the .java file throught the .jar file. Thanks in advance -- Ant
