Compiling java files in different packages with single javac command

i have java files in various package such as

com\pack1\pack2\pack3\one
com\pack1\pack2\pack3\one\a
com\pack1\pack2\pack3\one\a\b
com\pack1\pack2\pack3\one\a\b\c

com\pack1\pack2\pack3\two
com\pack1\pack2\pack3\two\a
com\pack1\pack2\pack3\two\b
com\pack1\pack2\pack3\two\c

I am compiling them as
javac com\pack1\pack2\pack3\one\*.java
javac com\pack1\pack2\pack3\one\a\*.java
javac com\pack1\pack2\pack3\one\a\b\*.java
..
javac com\pack1\pack2\pack3\two\*.java


I want to know is it possible to compile them with a single javac command(or may be lesser number of javac commands)
thanks
