log4j problem

[marco_ballarini]

Hi,

I've the following problem. I'm using a JDO library (JPOX, 1.1.5 version) in the SAP J2EE environment. I deployed it as a web service. The web service works well, the only problem is that JPOX is unable to log all his activities. Looking inside the trace files of the J2EE container it seems that JPOX is unable to find the log4j.properties file. But the strange thing is that the deployed jar contains the log4j.properties file and that it's at the right entry in the classpath. Following is the trace of the container:

log4j:ERROR Could not read configuration file from URL [jar:file:/F:/usr/sap/SJC/JC03/j2ee/cluster/server0/apps/sap.com/CrifShuttleWS/webservices_container/webservices/app_jars/CrifShuttleWS.jar!/log4j.properties].#

Hi,

This Issue normally arises when it cannot find the log4j.properties in the classpath.

please put a valid log4j.properties in the classpath or with any java classes. so that the file is loaded when the JVM is started up.
