Hi all,

I'm playing with json-rpc but can't get it to work.

I've tried the examples in fcl-web/examles/jsonrpc. I couldn't follow the readme as there are no lpi-files, so that the rttirpc.lpg does not work. But also this fails:

It fails at 'client.SayHello'. The invoke-logic is never called.

Maybe I miss a compiler-directive?

I have the jsonrpc in use in various commercial applications in production, so yes it definitely works.

But I must admit I have not looked at the examples in a long time.

I'll have a look this weekend.

Michael.

The .lpi files where not there because .lpi is in the ignore list, so I never noticed they were not in the repo :/

I committed them, and removed the *.lpi stance from the .gitignore file.

I corrected the example. The "classname" property in the json-rpc request has been renamed to "class", but the example was not adapted for this. This is now done.

I tested both client examples, both work.
