I have three files, all in the same directory:
DistContainer6.x10:
import x10.compiler.Native;
public class DistContainer6 {
public static def main(args:Array[String](1)) {
Console.OUT.println("DistContainer6 test: Starting");
val test = new HelloWrapper();
Console.OUT.println("DistContainer6 test: Complete");
}
}
HelloWrapper.x10:
import x10.compiler.NativeClass;
@NativeClass("java", "", "JavaHello")
public class HelloWrapper {
public native def this();
}
JavaHello.java:
public class JavaHello {
public JavaHello() {
// this space intentionally left blank
}
public void sayHello() {
System.out.print("hello from JavaHello");
}
}
Attempting to compile DistContainer6.x10 results in:
x10c: ----------
1. ERROR in
/nfs/17/tbitter/GAStuff/mcsweeny/examples/DistContainer6/HelloWrapper.java (at

JavaHello cannot be resolved to a type
----------
6 problems (6 errors)
x10c: Non-zero return code: 255
2 errors.
And also, JavaHello.java is blanked out. That is, the file is now empty.
Things I have tried:
- changing the @NativeClass line to: @NativeClass("java",
"java.util.concurrent.locks", "ReentrantLock") fixes all errors.
- creating a JavaHello object and calling sayHello from a @Native annotation in
DistContainer6 works
Any ideas?
Thanks,
