[zeromq-dev] Java on windows issue

[Tamara Kustarova]

Hi Robin,

you should run the latency tests in the following order:
1. zmq_server
2. j_remote_lat
3. j_local_lat

About the java pgm - we haven't tried it, but there is no reason why it 
shouldn't work.
We don't have any examples showing it, but we may create some later on.
You can have a look at the pgm throughput tests, that use simple pgm 
scenario.
If you come to any problems, just ask.

Tamara
