[Jython-dev] jython settings and tips

[<mdu...@ya...>]

Hi folks,

I discovered jython and it's cool but I encountered some problems may be 
you could help:


---------------------------------------------------------------------------
Do I have to set some environment vars or something in some particular files
to be able to compile the given examples (applets & bean).
I have the following error:

Compiling .java to .class...

Consider using the -C/--compiler command line switch, or setting
the property python.jythonc.compiler in the registry.

ERROR DURING JAVA COMPILATION... EXITING


---------------------------------------------------------------------------
I tried to embed some java JNI source code.
I could load the dll file, but I don't know how to manage to access the 
methods in the dll file.

in java it is:
public class DisplayMessage{

    static {
 System.loadLibrary("DisplayMessage");
    }

    public static void main(String[] args){
 System.out.println(printMessage("hello"));
    }

    public static native String printMessage(String s);
}


in my jython script, i tried:

from java.util import Lang
System.loadLibrary("DisplayMessage")
print(printMessage("hello"))


but it didn't work
how can I do?
