Can someone point me to a > document that explains what's up with Java licensing. There are two licenses you care about, the one with the Java 1.4 SDK, which says: B. Redistribution. This Agreement does not grant you the right to redistribute Software. Please refer to the following URL for information regarding the redistribution of Software if you are interested in redistribution: http://sun.com/software/products/appsrvr/appsrvr_oem.html ...in other words, Sun would like to sell you a license to run the software in production. However, you don't have to do that if you don't want to, as the other license for the Java Runtime Environment, at: http://java.sun.com/j2se/1.4.2/j2re-1_4_2_05-license.txt ...is freely available, and is what your end-users will need to accept in order to run your programs. > I mean, if I install jdk14 to develop java apps, can I resell those apps? Sure, you own the software you write-- obviously providing you don't include any of Sun's code with your software, indemnify Sun against all evil, etc etc. > There was a warning that said something about not redistributing binaries, > but it's too vague to tell me whether that means bytecode genereated by the > java compiler, or binaries that would result from me tweaking the jdk > itself. That's correct. You're not supposed to tweak the JRE itself, nor write software which changes things like how the java.* and com.sun.* packages work.
