[mary-users] client Java application

[Nikolai Kouznetsov]

Hello,

I am trying to see how I can run the TTS engine from within my Java 
application. To do this, I started with an example provided on MARy's 
website. When cling.dfki.uni-sb.de server is psecified, the clients works - 
it generates an utterance and plays it. When I use localhost, it does not 
work for me. When I run the provide maryclient from the bin directory it 
prodeuces the following:

java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)
Mary TTS client 4.3.0 (impl. 20101220)
Connected to localhost:59125, Mary TTS server 4.3.0 (impl. 20101220)


So, it looks like the maryclient can work with the localhost.




Please see the code and the generated output below.

Please advise. I would like to understand why you client code does not work 
if I  specify localhost as the name of the sever.

My best regards,
