logging in jotm

[vinodv26@xxxxxxxxx]

I am using jotm (1.4.3)/xapool(1.5.0) in tomcat 4.1.31. Both xapool/jotm are 
placed in common/lib.

My server has multiple webapps and each one needs to log into separate log 
file and have separate log4j conf file. Previously we used to have log4j in 
WEB-INF/lib of each of the webapps but when we shifted to jotm/xapool we 
moved log4j into common/lib as jotm/xapool need logging facility.

Now the problem arose that the last to load webapp's logger configuration was 
overwriting all the other webapps logger configurations. This was solved 
using classloader based repository selector 
(http://www.qos.ch/logging/sc.jsp). With this each webapp is having its own 
log configuration and application logs are working perfectly. 

The problem is with jotm/carols log messages, they are always going into 
first to load webapps log file. We need that jotm writes its logs based on 
the context from which its called. Meaning if webapp1 requests for user 
trasaction then jotm must log into webapp1's log.

Xapool which is also placed in common/lib is writing logs as per context, is 
this a problem with the way jotm uses logger or is something wrong in my 
log4j configuration ?

I looked at code of org.objectweb.jotm.TraceTm and noticed that it uses 
static Log instance
>> public static Log jta = LogFactory.getLog(JOTM_LOG_PREFIX + ".jta");

Doesnt this mean that jotm will always use the logger of that webapp which 
does first lookup of jotm transaction resource ?
