I resolved it myself. Two different ways. This is way too cool!!!!
public static int computeLoanInterest(final int amt, final float rate,
final int term) {
return (int) (amt * rate * term);
}
public static void getConnection2(final JavaScriptObject jso) {
Connection.get(new Callback<Connection>() {
public void onComplete(final Connection connection) {
invoke(jso, connection);
}
});
}
public static native void invoke(final JavaScriptObject jso, final
Object parameter) /*-{
jso(parameter);
}-*/;
public static void getConnection(final String instance) {
Connection.get(new Callback<Connection>() {
public void onComplete(final Connection connection) {
connected(instance, connection);
}
});
}
public static native void connected(final String instance, final
Connection connection) /*-{
$wnd.onConnect(instance, connection);
}-*/;
public static native void exportStaticMethod() /*-{
$wnd.computeLoanInterest =
$entry(@com.mhsystems.rsmapiproxy.client.SomeTestClass::computeLoanInterest(IFI));
$wnd.getConnection =
$entry(@com.mhsystems.rsmapiproxy.client.SomeTestClass::getConnection(Ljava/
lang/String;));
$wnd.getConnection2 =
$entry(@com.mhsystems.rsmapiproxy.client.SomeTestClass::getConnection2(Lcom/
google/gwt/core/client/JavaScriptObject;));
}-*/;
