Subject Re: IIOP tunelling over HTTP
Date Tue, 23 Mar 2021 19:56:01 GMT
Hi Francois

It is tested and working on TomEE 8.0.6; I did specifically test it using
this example:
https://github.com/apache/tomee/tree/master/examples/ejb-remote-call-2
before replying. Do let us know if you run into issues and we'll be happy
to help you out.
