Hello.

I have a problem with a ClassLoader

Without IStrategy It work. But if I try it run, then strategy stopped.

try{
File file = new File("c:\\myclasses\\");

// Convert File to a URL
URL url = file.toURL();
URL[] urls = new URL[]{url};

// Create a new class loader with the directory
ClassLoader cl = new URLClassLoader(urls);

// Load in the class; MyClass.class should be located in
// the directory file:/c:/myclasses/test/loaded
Class cls = cl.loadClass("test.loaded.LoadedClass");

} catch (Exception e){
e.printStackTrace(context.getConsole().getErr());
}

The problem in next code:
...
Class cls = cl.loadClass("test.loaded.LoadedClass");
...

Hi,

Please be sure that the compiled java class is located in the loading package. Try to put the attached zip package to the c:\temp directory, change the file variable to File file = new File("c:\\temp\\"); and try to load class with name Loaded: Class cls = cl.loadClass("test.loading.Loaded") ;.

For details please take a look at the following JForex Wiki page: https://www.dukascopy.com/wiki/index.php ... java_class

Hello,
I put interface Loaded into load_test.jar and write:

...
@RequiresFullAccess
@Library("C:/Dukaforecast/lib/test_load.jar")
public class LoadClassExample implements IStrategy {
...

...
Class cls1 = cl.loadClass("test.loading.LoadingClass");
console.getOut().println("Loaded: " + cls1);
Loaded l = (Loaded) cls1.newInstance();
l.getAnswer();
...

But I have exception:
java.lang.ClassCastException: test.loading.LoadingClass cannot be cast to test.loading.Loaded

Please replace the line Class cls1 = cl.loadClass("test.loading.LoadingClass"); with the following line:

Class cls = cl.loadClass("test.loading.Loaded");
