what are the libraries needed for flume log4jappender
Hi,

I would like to make my app directly write events to an flume agent.

What are the libraries needed to add into my application?

I have tried to add the following three but runs into class not found
errors.
log4j.properties are as follows:
log4j.rootLogger=TRACE, flume
log4j.appender.flume = org.apache.flume.clients.log4jappender.Log4jAppender
log4j.appender.flume.Hostname = example.com
log4j.appender.flume.Port = 44444
log4j.appender.flume.layout=org.apache.log4j.TTCCLayout
Error In Initialization

Classpath:
C:\\workspace\mongodb\Mongodb\bin;C:\test\log4j-1.2.16.jar;C:\test\flume\flume-ng-core-1.4.0-SNAPSHOT.jar;C:\test\flume\flume-ng-log4jappender-1.4.0-SNAPSHOT.jar;C:\test\flume\flume-ng-sdk-1.4.0-SNAPSHOT.jar
