I'm not clear what you mean by "access the Class Database". Connect Atelier to the SAMPLES namespace and you'll be able to view/edit classes from the SAMPLES database. Please expand on what else you're trying to do.

Alex, if you code it as an instance method (private or public) then you won't be able to call it from a classmethod (private or public) unless the caller has (or creates) an instance of its class. In other words, the decision about whether to code an instance method or a classmethod is surely independent of the decision about whether to mark that method private or public, no?

Using my DC mod superpowers I changed this post from a Question into an Article.

The page at http://www.georgejames.com/ws/ looks like this:

Use the link I've highlighted.

You may also need some of the Hints & Tips entries, and/or Patches entries.

If you get stuck I suggest you contact me directly, using the "John Murray" link near the top of that page.

Brian, if you don't mind using 20-year-old software, the link in my previous reply goes to a page from where I think MSM-Workstation can still be downloaded.

I have removed the "Developer Community FAQ" tag from this post. Please do not use this tag.

What sort of webserver is at http://xyzx.x.edu ?

How was it set up and configured to use CSP Web Gateway?

I suggest you contact InterSystems Support (a.k.a WRC) for help resolving your issue.

No, it's not possible to do this with Caché.

Some old-timers (like myself) may recall MSM-Workstation, which could do this kind of thing.

That'll be the problem, because /api/atelier is how Atelier talks to the server.

What is the $ZVERSION string of the remote server?

So does the following URL (or similar) give you access to Portal on the remote server?

http://xyz.x.edu/csp/sys/UtilHome.csp

Try port 57772.

In other words, use the same port number as you use when accessing InterSystems Management Portal.

Yes, that's what I mean.

See also my post here which documents how to set up %ALL, and how it doesn't actually apply to 100% of your namespaces.

Well, the %Z* names were safe from overwrite by InterSystems, until they came out with the %ZEN package

A CACHE.DAT database file can be mounted, read and modified by any instance of Caché, including one running "locally", by which I assume you mean "on your workstation".
