If a self-contained application that uses Xerces and other Axis classes deploys correctly but displays errors when running, the problem is a class-version conflict between the classes shipped with EAServer and those used by the application. To solve this problem, you can either:
Use the disableResolveFirstBySystem option when you deploy an application, to tell EAServer to resolve classes using the internal class loader first, or
Remove the application’s copy of the classes. This may not work, because the application may run only with its own classes.
