Hi, Also in this thread, I can't but refer to this other thread of yours and in particular to post #4.
To resume, if you open a command prompt from the "Lightstreamer" folder of the Server installation package, you should run a command like this:
Code:
java -cp "lib/*;lib/log/*;lib/core/*;lib/adapters/*;lib/proxy/*" com.lightstreamer.LS conf\lightstreamer_conf.xml
This is the simplest way to run the Server. It will log "No com.lightstreamer.kernel_lib_path defined; using a unique ClassLoader; ignoring any other _lib_path supplied" at startup, but this should not prevent it from working.
Launched in this way, there may be problems only in case of conflicts between third-party libraries used by the Server and libraries used by your Adapters, but they can arise only after the initial startup.
In particular, the classes from Logback that you can't load are in the "lib/log/*" part of the classpath shown.
Please try to do exactly the same and confirm if it works.
Then, use that as the baseline that you should refer to when setting up the launch in you own context.
