CayenneDataObject over WebService

[Oilid Adsi <Oi...@freenet-ag.de>]

Hello,

 

how is it possible to send and receive an own generated class of
CayenneDataObject-type over a WebService (for example Apache Axis 1.3)?

 

We made the experience that axis will throw an exception because the
CayenneDataObject is not serializable.

 

As workaround we have built another object (webservice-bean) with the
same getter- and setter-methods 

and merged the CayenneDataObject-class and webservice-bean together by
using java5 method-reflections. 

 

But this is not really nice...

 

 

Thanks for help!

Have you looked at the Cayenne ROP project? (http:// 
cayenne.apache.org/doc/remote-object-persistence-guide.html)

This already does exactly what you need and is dead simple to set up.  
It uses Hessian as the 'web service' - really just a simpler, faster,  
smaller and much easier alternative to SOAP. We use both SOAP and  
Hessian in our application, and if we could I'd gladly strip out the  
clumsy Axis for Hessian any day.

All Cayenne objects are serialised and sent across the network  
between client and server.
