Java errors when trying to compile a Red5 server sample

Question

I'm trying to a build a Red5 server sample using the tutorial here. I have done all the things including adding red5.jar, commons-logging-1.1.1.jar but when i try to build the my own jar file using ant I get the following errors!

BUILD FAILED
C:\Users\MediaStudio\workspace\Sample\build.xml:8: Compile failed; see the compiler error output for details.

I'm using the classic version of Eclipse (not sure if it's important or not but!)

Answer 1

I solved this problem by adding the classpath attribute to the javac command inside the build file pointing to the right jar files like the line below:

classpath="${lib.dir}/red5.jar:${lib.dir}/commons-logging-1.1.1.jar"
