The org.apache.commons.logging.LogFactory class is required but cannot be found.

If you don't have the [url=http://jakarta.apache.org/commons/logging/]commons logging library[/url], go and get it.

If you have it, make sure it is in the [url=http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/classpath.html]classpath[/url].
