Subject [jna-users] Synchronized output between Java and c

Hi, I am calling a c library from Java using JNA on Ubuntu Linux 8.04. The problem is when I try to print output for debugging the output of the c library itself is not synchronized with the Java output. So for example if I call function printDfa(DFA* dfa) in c from within Java as in the following code ,

(Note that dfa1, dfa2 are Java objects that encapsulate the corresponding c structures of type DFA and printDfa calls the actual c function printDfa.)

System.out.println("printing dfa1"); dfa1.printDfa(); System.out.println("printing dfa2"); dfa2.printDfa();

the printDfa output got mixed with the debugging messages before and after this function.

Is there any suggested solution to this other than reimplementing the c function in Java. Also what is the best way to debug the java program along with the c library as a whole unit. Is there a way to use Java debugger.

Thanks Muath
