NullPointerException when trying to start server...

[drdaz]

Hi there

I'm attempting to run rplay on Ubuntu 10.04 (32-bit) under the Sun Java VM. I have built Apple mDNSResponder 107.1 and installed it (along with the Java libraries).

When I attempt to start the RPlay server by clicking on the button, I get the following:

Exception in thread "Thread-1" java.lang.NullPointerException
at LaunchThread.run(LaunchThread.java:97)

Looking at the code, I'm not sure why the error occurs here, since it appears the object shouldn't be null (you initialize the thing in line 75).

I'll debug some more if I get the chance... but if you know of some reason why things shouldn't be working with my setup (OS or dependency versions) then you'd save me some time by letting me know ;-).

This is probably due to a missing libjdns_sd.so. Make sure you enter mDNSPosix and "make os=linux Java". After that, you should end up with a .jar and the libjdns_sd.so. Make sure they're in your path and it should work.

New version of RPlay includes JmDNS which eliminates this issue. Please try again.
