Hi,

I have add a logging package (log4j) to a java plugin node. The logging appears to work fine, but the WMQI log file : 'syslog.user' reports the following :
    Failure to locate Java class org.apache.log4j.nt.NTEventLogAppender
    Failure to locate Java class org.apache.log4j.xml.DOMConfigurator
The log4j.jar is located in the jplugin folder and contains both the aforemention classes. From the java plugin node I can call

Code:
 System.getProperty("java.class.path")


which returns the classpath from which I can verfiy that the log4j.jar is indeed in the classpath.

This error is reported when the broker is recycled. Is this a class loader issue? And if so, where can I put the jar or how can I ensure the classes are available when the broker loads the plugin jars?

Thanks in advance,
John

Put it in the classes folder.
