I am running Tomcat 5.5.23 on a Windows XP machine with JDK6. I have only one
webapp
(others are standard webapps packaged with Tomcat). During Catalina bootstrap,
I see the null pointer exception (trace below) that looks quite like #39631
(SEE http://issues.apache.org/bugzilla/show_bug.cgi?id=39631).
I do not have any libraries in endorsed or shared directories. I am using ver
1.2.14
of Log4j, ver 1.0.4 of commons logging and commons logging API
(commons-logging-1.0.4.jar,
log4j-1.2.14.jar, commons-logging-api-1.0.4.jar).
Is this caused by incompatible jar versions? I am not sure how to troubleshoot
this further.
Pl help,
Thanks,
