it's due to the database data type.

about the tutorial

1. when prototype "person", should the "type.properties" file in "application_dir/person" or "application_dir\simplehop\person" as in the tutorial?

2. where should the "html.link" be put?
is it "application_dir\global" or "application_dir\people\global" as in the tutorial?

Helma/Antville on IIS

I'm running antville on helma on IIS using the JK isapi_redirect.dll. Everything works fine. What I would like to accomplish is being able to access my blog via mike.blog.escapenet.ch instead of http://blog.escapenet.ch/antville/mike
Any howtos on this subject?

Kein Zugriff auf /manage/

Hallo, meine Installation läuft eigentlich, nur wenn ich den Link zu manage aufrufe (über Browser von einem entfernten Rechner) erscheint die Fehlermeldung:
Access from address 80.142.xx.xx denied.
Wie kann ich die Zugriffsberechtigung herstellen?

in server.properties in der zeile mit "allowAdmin" die IP von der aus du zugreifen möchtest eintragen

(ps: die chancen schnell und verlässlich antworten zu enthalten sind auf den mailinglists eindeutig besser als hier mittels der comments)

How can I access Java classes from macros?

I would like to access Java classes that I have wrote, and use them from macros and functions and get their output to be displayed in my skin?
Is there a way to do that?

Have a look at the relevant section in the Rhino documentation, and be sure to put your classes in the classpath (or jar 'em up and put the resulting archive in lib/ext).
