PQ47050: ADD NEW FUNCTION TO ALLOW THE WEBAPP CLASSLOADER TO LOAD BEFORE THE SYSTEM CLASSLOADER


APAR

APAR status
Closed as program error.

Error description
Add new function to allow the webapp classloader to load ahead
of the system classloader. This will allow customers to use
different versions of common java libraries (for example XML4J
and Xerces) than those that are shipped with WebSphere.
Local fix
Problem summary
WAS WebApp classloader to load ahead of the system classloader.
This allows customers to use different versions of common java
libraries than the ones shipped with WAS.
Problem conclusion
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
to be added to the command line of the application server:-Dcom.ibm.servlet.classloader.delegate=false
Temporary fix
delegcl.jar).
