Sandro,

The import statement was missing from your code so I couldn't tell which
API you were using. The other reason I ask is that certain logging
frameworks do stack scanning (depending on configuration) to determine
the
invoking class which could be the source of your problem. So the question
is does the call to getThis() cause the StackOverflowError or a subsequent
call to "info()"? If you just send the datat to stderr do you
get the
error?

>>        /** Logger named "ApplicationTracer"

LoggingFactory.getLogger("ApplicationTracer");

well, it depends on configuration which logging implementation is used...
in this case it is log4j...

i thought that the pointcut

>>        pointcut traceClasses() :
>>                within(com.namics.common..*)
>>                &&
!within(com.namics.common.log*..*)
>>                &&
!within(com.namics.common.aop..*);

will reduce the scope correctly (only within com.namics.common.* but not
...)

are static mehtod that bad for getThis()?? i mean produce a
stackoverflow...?

kind regards,
sandro

Sandro,

Can I ask what logging implementation you are using? Also does your program
have static methods? In which case getThis() will return null. You may
want
to check this or code separate advice for static methods.
