> Key: AXIS2-4859
> URL: https://issues.apache.org/jira/browse/AXIS2-4859
> Project: Axis2
> Issue Type: New Feature
> Components: codegen
> Affects Versions: 1.5.2, 1.5.3, 1.6.0
> Reporter: Dean Holdren
> Assignee: Ping Liu
> Attachments: iu.patch, iu_1_5.patch, iu_trunk.patch,

> Problem: Service provider adds an optional element to the responses it sends,
> assuming client can handle, while client is unaware and has not (or cannot)
> retrieve updated WSDL and regenerate client. Axis2 client generated with
> ADB, cannot handle and throws an exception.
> Solution:
> Optional "Ignore Unexpected Elements" mode for wsdl2java using adb - allows
> for forward-compatible clients that can recover from unxpected elements in
> service responses.
> Based on the work in Issue 3037 - This patch is more up to date, is for both
> trunk and 1_5 branch, handles more scenarios, and will correctly parse the
> portion of the response after the unexpected element.
> To use, pass the "-Eiu" parameter to wsdl2java
> Handles the following scenarios:
> 1) unexpected element in a xsd:choice, xsd:any, xsd:all
> 2) appended unexpected element in a xsd:sequence.
> For xsd:sequence, the unexpected element, and subsequent elements within that
> sequence are not captured. If a service adds a new element within a sequence,
> it should be *appended*, as the generated client is strict with ordering, and
> can't differentiate an out-of-order sequence from an additional inserted
> element.
