Hi all,

I have written a Tcl extension in Java:

public class JavaTest extends Extension {
public void init(Interp interp) {
/* Register some commands... */
interp.createCommand("creole_JavaTest",
new creole_JavaTest());
}

public static void SetComponentHome(String path) {
System.out.println("JavaTest::SetComponentHome("+path+")");
creole_JavaTest.creole_JavaTest_home = path;
}
} /* class JavaTest */

My "JavaTest" that is an extension, has a new method "SetComponentHome".
Is there a way to call this method?

I can load the extension with:

java::load -classpath path JavaTest

but the JavaTest class seems to disappear after the extension gets
loaded. Any ideas on how to call SetComponentHome?

the docs say you can use java::call to invoke static methods
on java classes

does that not work?

No. It does not see at all the JavaTest class.
I can load it, its init gets called, but somehow it is not visible as a
class in tclBlend.
