APAR: PQ47050 V3.5.2 & V3.5.3 Description: New function to allow WebApp classloader to load before system classloader How to apply: - create a directory to store the jar file (e.g. c:\WebSphere\AppServer\efix) - copy pq47050.jar to the directory - add the directory/jar file to the begining of the admin server's classpath in admin.config: com.ibm.ejs.sm.adminserver.classpath=C:/WebSphere/AppServer/efix/pq47050.jar... - Stop and restart the Admin Server Important information about this fix: PROBLEM CONCLUSION: The code has been changed to allow you to choose the delegation model for the WebApp classloader. If you choose delegate=true (the default) then the system classloader is used to load classes before the WebApp classloader.If you choose delegate=false then the WebApp classloader is used ahead of the system classloader. This way customers can have newer versions of common java libraries in the WebApp classpath and they should not conflict with the package in the system classpath. The following property needs to be added to the command line of the application server: -Dcom.ibm.servlet.classloader.delegate=false
