RE: Strange weblogic problem with new jarfile name (WAS: Why is t he version number included in the log4j jar file name?)

[Matt Cox <MC...@DeWolfe.com>]

Are you using WL 6.1 SP 2?  I was looking at some threads on bea developer's
newsgroups where users where having problems with jars working in SP 1 but
not in SP 2. I wonder if this is related.

yes, the first example i provide is with log4j.jar named as such.  when i
change 
it back to log4j from the numbered name, and do a clean deploy it works once

again.

Have you tried renaming log4j-1.2.4.jar to log4j.jar and then re-deploying
it?

we just upgraded log4j to the 1.2.4 jar. 

we encountered a very very strange problem (using Weblogic 6.1), that seems
to 
be 
directly related to having the version number in the filename of the jar. 

weblogic would fail upon access to a servlet that depended on log4j
(basically 
every 
servlet, since they all inherit from a class that contains an instance of
Logger 
(used to 
be Category)). 

it would fail because it couldn't find the class, and yet, the
log4j-1.2.4.jar 
file was 
in WEB-INF/lib 

upon closer examination, weblogic copies the jar files that a web-app is 
dependent on 
into its own special directory within WEB_INF, and mangles the names.  to 
illustrate, 
here is the (edited) output of a find command in our deploy directory (our
web-
app is 
named "ts2"): 

bash-2.03$ find . -name '*.jar' 
. 
. 
./ts2/WEB-INF/lib/log4j.jar 
. 
. 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/log4j59854.jar 
. 
. 

note that log4j.jar is mangled into log4j59854.jar. 

now, after renaming log4j.jar to log4j.1.2.4.jar and clearing out the deploy

directory 
and redeploying the web-application, this is what it looks like: 
. 
. 
./ts2/WEB-INF/lib/log4j-1.2.4.jar 
. 
. 
. 
(all jars in the weblogic directory displayed): 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/startup59860.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/jaxen-full59861.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/jdom59862.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/commons-
beanutils59863.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/soap59864.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/commons-
collections59865.jar 
./ts2/WEB-INF/_tmp_war_edAdmin_edAdmin_ts2/WEB-INF/lib/saxpath59866.jar 

note, that log4j-1.2.4.jar is now ignored, and i cannot execute a web 
application. 

now, i recognize that this is, in fact, a weblogic error and not a log4j
error.  
but, i 
mention it here because of the recent discussion regarding the name change,
in 
case 
anyone might come across a similar issue.  has anyone else encountered this?
