Hi,

thanks for this hint! you are right, I tested this in a WLP 10.2 consumer - JBoss Portal 2.6.4 producer scenario and managed to pass data using BEA's custom transfer mechanism. Basically, from WLP portlet backing file you can add the object to the request something like:

request.setAttribute(MarkupRequestState.KEY, "TEST");

The WLP consumer will serialize, encode this object (Base64) and add an extension to the SOAP message (getMarkup) with the result, something like:

<v1:extensions>
    <ext1:MarkupRequestState xmlns:ext1='urn:bea:wsrp:ext:v1:types'>
        <ext1:state>
                rO0ABXQAC0dFT1JHRSBURVNU
        </ext1:state>
    </ext1:MarkupRequestState>
</v1:extensions>

As you mentioned, this value can be extracted from the SOAP message, Base64 decoded and deserialized on the JBoss Portal side using a custom JAX-RPC handler (for the MarkupService). 

However, a downside of this approach is that, in case of sending custom objects, you need to have the same version of the class on the producer as well, otherwise the deserialization will fail. Therefore is safer to use primitives and common java objects.

Cheers,
George
