Subject Re: svn commit: r551968 - /geronimo/server/trunk/modules/geronimo-transaction/src/main/java/org/apache/geronimo/transaction/manager/TransactionImpl.java
Date Sat, 30 Jun 2007 01:13:50 GMT
After many attempts to log stack traces I think I've found that for  
log4j at any rate

log.error(new Exception("message") just logs the message but
log.error("watch this!", new Exception("message")) logs the stack  
trace from the exception.

I had some more changes to TransactionImp so I changed to the latter  
style in rev 552073.

thanks
