NullPointerException when restarting a Web App
Summary: NullPointerException when restarting a Web App
Product: Log4j
Version: 1.2
Platform: Other
OS/Version: Windows NT/2K
Status: NEW
Severity: Normal
Priority: Other
Component: Other
AssignedTo: log4j-dev@jakarta.apache.org
ReportedBy: anjiloh@tecnes.com
I've got a Windows 2000 Server, I'm using Jakarta-Tomcat 4.1.24, Struts 1.1rc1.
My tomcat works as Windows Service.
My webapp is provided as WAR file.
If I stop/start the Windows Service (Via Control Panel/Administrative Tool)
the webapp is deployed correctly. If I use the Tomcat Web Application Manager
and I stop the webapp, I replace the WARfile with a new one and I start the
application (http://servername:8000/manager/html/start?path=/PM) I've got the
following exception:
