Hi,I am new to "Mina". I am having problems getting the project-examples to work. I am using the following packages: - mina-1.0.2 - backport-util-concurrent-3.0 - slf4j-1.3.0 - spring-framework-2.0.3 The least of my problems is that "spring-framework" doesn't build. "slf4j" seems to be a bigger problem; when I try to run various MINA examples (eg "echoserver") I get the following error: Exception in thread "main" java.lang.ExceptionInInitializerError at org.apache.mina.common.ExecutorThreadModel.<init>(* ExecutorThreadModel.java:81*) at org.apache.mina.common.ExecutorThreadModel.getInstance(* ExecutorThreadModel.java:71*) at org.apache.mina.common.support.BaseIoServiceConfig.<init>(* BaseIoServiceConfig.java:46*) at org.apache.mina.common.support.BaseIoAcceptorConfig.<init>(* BaseIoAcceptorConfig.java:36*) at org.apache.mina.transport.socket.nio.SocketAcceptorConfig.<init>(* SocketAcceptorConfig.java:48*) at org.apache.mina.transport.socket.nio.SocketAcceptor.<init>(* SocketAcceptor.java:63*) at org.apache.mina.transport.socket.nio.SocketAcceptor.<init>(* SocketAcceptor.java:84*) at org.apache.mina.example.echoserver.Main.main(*Main.java:49*) Caused by: *java.lang.IllegalStateException*: Logging factory implementation cannot be null.

SLF4J requires one more JAR file. Please try to download the latest version of slf4j-simple or slf4j-log4j (+ log4j.jar) and add it to the build path. HTH, Trustin -- what we call human nature is actually human habit -- http://gleamynode.net/ -- PGP Key ID: 0x0255ECA6
