[jacorb-developer] Bad type on operand stack error when using JacORB and JBoss modules

[Rob Ratcliff]

Hi ,

I found this old article on reworking JacORB to work with Felix by
compiling without RMI support using -Dno-rmi=true.

http://apache-felix.18485.x6.nabble.com/Bundelizing-Jacorb-getting-screwed-tp4843264p4843270.html

What's the equivalent maven command to do this?

Any advice on this?

Rob
