This subsection describes the support range of the javaee:handler-chains element.

• You can only code one javaee:handler-chains element as the root element of the handler chain configuration file. You cannot omit this element.
• You can specify the javaee:handler-chain element as the child element. If you code a child element other than the javaee:handler-chain element, an error message (KDJW30019-E) is output to the standard error output and the log.
• You can only specify the standard attributes of the XML specifications and XML Schema specifications (such as the xmlns attribute). If you specify attributes other than the standard attributes of the XML specifications and XML Schema specifications, an error message (KDJW30019-E) is output to the standard error output and the log.
