Error description
A ClassNotFoundException might be thrown for the class com.ibm.xml.logger.WSLoggerUtil if a context class loader has been specified in a program that uses the Thin Client for the Feature Pack for XML or if classes from the Thin Client are loaded using an instance of java.net.URLClassLoader.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0 * **************************************************************** * PROBLEM DESCRIPTION: If the Feature Pack for XML Thin * * Client is used in a program that * * specifies a context class loader, or * * if the program loads classes from the * * Thin Client using an instance of a * * URLClassLoader, a * * ClassNotFoundException might be * * thrown for the class * * com.ibm.xml.logger.WSLoggerUtil. * **************************************************************** * RECOMMENDATION: Install a fix pack that contains this * * APAR. * **************************************************************** In trying to initializing its logging framework, the Feature Pack for XML Thin Client checks whether a user-specified logger has been requested, and if a user-specified logger has been requested, it attempts to load the implementation class for that logger. If a context class loader has been specified, the Thin Client will use it to attempt to load the logger's implementation class. If no user-specified logger has been requested, the Thin Client attempts to use the class com.ibm.xml.xml.logger.WSLoggerUtil. However, the Thin Client still attempts to use any context class loader to load that class, rather than using the class loader that loaded the logging framework itself. If WSLoggerUtil is not available to be loaded by the context class loader, a ClassNotFoundException results. Finally, if the classes in the Thin Client are loaded using a URLClassLoader, a ClassNotFoundException results due to an explicit reference to the WSLoggerUtil class in the logging framework LoggerUtil class. With other kinds of class loaders, that reference does not result in a ClassNotFoundException
Problem conclusion
The first problem was resolved by changing the logging framework to only use the context class loader in attempting to load a user-specified logger, not the default logger com.ibm.xml.xml.logger.WSLoggerUtil. The second problem was fixed by changing the explicit references to com.ibm.xml.logger.WSLoggerUtil within the com.ibm.xml.logger.LoggerUtil class to references encoded in String values instead. The fix for this APAR is currently targeted for inclusion in fix pack 8.0.0.2.
