Hi there,
for some days I am struggling to get the FTPServer running on my Tomcat
instance. I have my implementatio for the FTPServer, as I need it, running in a
jUnit-test environment but as soon as I deploy it to tomcat I get the following
Error (not Exception(!)) as soon as a client connects to the FTPServer:
Exception in thread "pool-1-thread-1" java.lang.IncompatibleClassChangeError

I am totally unsure which component is in conflict and causes this error. I
think that SLF4J and Mina-core should be in the correct version. Can this error
come because of some weird problem with AOP components coming with Spring?
This is how I add the dependencies to Spring:
<dependency>
<groupId>org.apache.ftpserver</groupId>
<artifactId>ftpserver-core</artifactId>
<version>1.0.6</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.mina</groupId>
<artifactId>mina-core</artifactId>
</dependency>
Thanks for help,
Mit freundlichen Grüßen,
David Weisgerber
