log4j的錯誤信息 - 批處理

Question

在批處理開始陪我吃飯Simphony模型時，我收到此錯誤信息：

log4j:WARN No appenders could be found for logger (RLFA.society3.run.1.1). 
log4j:WARN Please initialize the log4j system properly. 

這裏涉及的log4j http://repast.sourceforge.net/docs/tutorial/SIM/Frequently%20Asked%20Questions.html#FrequentlyAskedQuestions-log4j不會在所有幫助，因爲我得到的答案只有在開始批量運行時纔會出現問題。通常啓動模型時一切都很好。而且我也無法適應其他任何log4j問題/答案，因爲這個問題在Repast Simphony中似乎相當具體。

之前有人遇到過這個問題並解決了它？或者也許一個想法，這RLFA是什麼？

注意：錯誤發生在模型完全初始化時，在第一步中。

感謝每個幫助，

安迪

編輯：在velocity.log我發現這個測井公司，它說，一個VM_global_library.vm是失蹤 - 但是，這有助於進一步？

問題是我忘了在Repast Simphony中定義一個輸出器。
