javac in jdk1.3 (HELP!!!)

I have a basic doubt.....

there seems to be 2 files: javac and oldjavac in 1.3....i would like to know this - if i use oldjavac in 1.3 will it follow the compilation procedure as if it were compiling in 1.2?

Also assuming we have 2 packages that use each others classes, it looks like i wd have to compile both packages independently ( unlike 1.2 where dependency classes were compiled automatically).....now my problem is that when i compile the first package it says the second's classes are not found and vice versa......

How do is solve this.....
