LogConfigurationException while running STRUTS with two applications
in iPlanet
We are running two STRUTS applications using Log4j in iPlanet 6.5 Application servers. We have deployed struts, commons-beanutils, common-collections, commons-digester, commons-logging, commons-validator and log4j under the WEB-INF/lib and packaged them as separate ear files for each application separately. The Action servlet in each application is deployed with a different name. Each application has an initializer servlet that is invoked at application server startup and load the Log4J configuration.
The above works fine with only one application and also on occasion with both applications. However, we are getting intermittent errors when running both applications together when the requested JSP fails to load with an error in the application server kjs logs. We have observed the following pattern of errors: (with debugging turned on)
Always starts with one LogConfigurationException (see Error #1 below). This error does not always happen at startup. It can happen even after some usage of the applications. Once this error has occured, we get a java.lang.NoClassDefFoundError (see Error #2 below) when the JSP page load occurs in the application.
Has anyone seen this error ? Any insight would be much appreciated.
Error #1

Re: LogConfigurationException while running STRUTS with two applicationsin i
Planet
Posted by Kent Sølvsten Rasmussen <ke...@aarhusmail.dk>.
In later versions, commons-logging has been separated in 2 jarfiles, 1. commons-logging.jar and 2. commons-logging-api.jar. This might be the case here. Maybe your are using a commons-logging-api from the applicationserver itself.
Try putting a commons-logging-api.jar inside your webapps too.
(btw this is actually a USER question)
