Re: Exception in thread "main" java.lang.UnsatisfiedLinkError: no NTEventLogAppender

It's not enough to have NTEventLogAppender there, you also have to put it on the PATH.
Commenting the line has no side-effects except that log will not be written into Windows event log.

  Hi Sasa,

  Thank you.

  But I find the "NTEventLogAppender.dll" is actually already in the indicated directory in my pc. The exception still occurs. Please suggest. 

   

  I have a work-round way to eliminate the exception is to comment out the line in shark.conf :

  #log4j.appender.NTEventLog=org.apache.log4j.nt.NTEventLogAppender

  But I don't know its impact.. ?

   

  Best Regards,

  He Wei

  There is no NTEventLogAppender.dll is not in ypour path. Look at the shark scripts for Windows, and you'll se the line:

   

  set PATH=lib\contrib\ext;%PATH%

   

  The appropriate dll is placed in lib\contrib\ext.
