-----------------------------------
Resolution: Fixed
> JAX-WS Needs a property to prevent lossy transformations before the
> application handlers are called
> ---------------------------------------------------------------------------------------------------
>
> Key: AXIS2-4502
> URL: https://issues.apache.org/jira/browse/AXIS2-4502
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: jaxws
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Problem:
> When a message is received, we want to quickly transform the message into the
> "final form" to reduce memory and increase speed.
> For example, in the JAX-WS server inbound case, the message payload is
> transformed into a JAXB object (which is what the JAXWS @WebService needs).
> However if the customer has installed a JAX-WS soap handler AND that handler
> inspects the message payload (the contents of the soap Body), then
> the JAXB object must be "re-transformed" into an SAAJ tree.
> This re-transformation is slow and is also "lossy". For example, the
> namespaces in the original message and post-JAXB message may be different.
> Most SOAP Handlers don't touch the SOAP body. The JAX-WS specification does
> not provide a mechanism to allow SOAP Handlers to tell the engine their
> "intent".
> So we want to expose an option that would allow a customer (developer or
> administrator) to preserve the original message.
> Solution:
> The Axis JAX-RPC web service engine had a property call "high fidelity". The
> intention of the property was to preserve the original message.
> I am working on a fix to introduce a "jaxws.payload.highFidelity" property.
> The property will be available for programatic property (used by the
> developer )or as a configuration parameter (used by an administrator).
> **
> * Context Property:
> * Name: jaxws.payload.highFidelity
> * Value: Boolean.TRUE or Boolean.FALSE
> * Default: null, which is interpreted as FALSE....engine may set this to
> TRUE in some cases.
> *
> * Configuration Parameter
> * Name: jaxws.payload.highFidelity
> * Value: String or Boolean representing true or false
> * Default: null, which is interpreted as FALSE
> *
> * Description:
> * If the value is false, the jax-ws engine will transform the message in
> the most
> * performant manner. In some cases these transformations will cause the
> loss of some information.
> * For example, JAX-B transformations are lossy.
> *
> * If the value is true, the jax-ws engine will transform the message in
> the most loss-less manner.
> * In some cases this will result in slower performance. The message in
> such cases is "high fidelity",
> * which means that it is a close replica of the original message.
> *
> * Customers should accept the default behavior (false), and only set the
> value to true if it is
> * necessary for a SOAP Handler or other code requires a high fidelity
> message.
> *
> * The engine will first examine the Context property. If not set, the
> value of the Configuration
> * property is used.
