[Jython-users] Py.runCode(...) question

[Nick C. <ni...@sr...>]

Hi,

Can someone tell me why the code below doesn't print hello.

public class EmbedTest {

  private String func = "def func():\n\tprint 'hello'";

  public void run() {

    // NullPointerException without creating an interpreter
    // need to initialize the runtime?
    // better way to do this?
    PythonInterpreter i = new PythonInterpreter();
    PyCode code = __builtin__.compile(func, "<string>", "exec");

    System.out.println(code.__class__);
    System.out.println(code.__dir__());
    System.out.println(code.__getattr__("co_argcount"));
    System.out.println(code.__getattr__("co_varnames"));
    PyStringMap locals = new PyStringMap();

    //Py.exec(code, locals, locals);
    Py.runCode(code, locals, locals);
  }

  public static void main(String[] args) {
    try {
      EmbedTest test = new EmbedTest();
      test.run();
    } catch (Exception ex) {
      ex.printStackTrace();
    }
  }
}

The compile call returns a PyTableCode object but the call to Py.runCode
doesn't have any noticeable results.

thanks,

Nick
