[Json-rpc-java] Re: Json-rpc-java Digest, Vol 8, Issue 9

[jv]

well, I haven't thought too much about it. it's an investigation
development, so I'm not really reluctant to apply an open licensing
scheme... Something like Apache or LGPL should be nice. I can send you
the current example, but it's in Spanish (as you have already guessed,
English is not my native language ;-) ). But if you are really
interested  I can translate it this week and package it in a
convenient way.

thanks!!
