Receive the File & line number

[Feigin Yaron <Ya...@comverse.com>]

Hi all,
Is there an optimized way via the log4j functions to receive the line we
are printing from without printing all stack and manipulating it?
In C/C++ there is a __LINE__ macro that do the job...
Is there an equivalent in java for that?
Many thanks,
Yaron Feigin

Can't you use %L in the configuration file for the pattern?

ConversionPattern=(%F:%L)

Generates file name and line number separated by a colon...   
MyFile.java:1

PatternLayout.html

It's not optimized, however.  I don't believe there's a simple,  
optimized, means of getting the line number from java (otherwise it  
probably would be used by Log4J inherently).
