The application works fine in tcServer except for the following error:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

What is the meaning of class path, and where can I find it?

I am a newbie, please explain.

That error means you're missing a JAR file for an actual implementation of SLF4J. What you should do is download an implementation like Logback or Log4j (use the log4j-slf4j-impl JAR, not the log4j-to-slf4j one) and add it to your lib directory in tcServer.

Your class path is simply the various library JARs that contain compiled Java code that supplements your application. Check out the related questions to the right for other similar problems with missing SLF4J JAR files.
