Could you send the stack trace? -- Ceki On 06/06/2011 10:50 PM, Stephen Schaeffer wrote: Hi all, I'm attempting to use the DBAppender, with the MySQL dialect. I am unable to actually put any records into my DB however. It seems that the culprit is that in DBAppenderBase:append, there is a call to subAppend, which is implemented either in Access, in which case it takes an AccessEvent as it's first argument, or in Classic, in which case it takes an ILoggingEvent as it's first argument. What it is actually passing is a LoggingEvent (no initial I) object, and so I'm getting ClassCastExceptions, and nothing in my DB. I'm assuming that someone out there has this working, and I'm just wondering what I'm doing wrong.
