Well, java0x1 is a Java ref to an object. You need to pass it to a Java method
like so:
public class Test {
static String str;
public static void mymethod(String in_str) {
str = in_str;
}
}
Then you would invoke this Java method from Tcl like so:
set jstr [java::new String "A Java String"]
java::call Test mymethod $jstr

P.S.
You could also look into setting a field of a Java object using java::field.
