How to log axis2 errors and where can I see it?

Hi,
How can i set axis2 logging facility? I deployed my axis2.war on Resin 3.1.9. Then I created StockQuoteService.aar based on the ant task at axis2's samples (C:\AXIS2_HOME\axis2-1.4.1\samples\quickstart). I dropped this .aar file to C:\resin\webapps\axis2\WEB-INF\services. I then started resin using httpd.exe. Axis2 has been deployed successfully and I was able to get to the happy page. However, when I tried accessing the StockQuoteService's method like http://localhost:8080/axis2/services/StockQuoteService/getPrice?symbol=IBM, i got an INTERNAL SERVER ERROR. How do i resolve this? And how do I set up logging facilities in axis2 so that I could view the error logs to see what's wrong. Did any of you encounter similar errors before?

Thanks
