[fpc-devel] jsonrpc - does it still work?

[Joost van der Sluis]

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?
