[news.eclipse.technology.riena] Re: project similar to riena

[Christian Campo <christian.campo@xxxxxxxxxxxx>]

Hi Nicolas,

Riena implements Remote Services which enables components to make calls running OSGi service on a remote machine
using the business interface. We are planning a first milestone version end of February by which we will also have some
documentation on the wiki how to create services, how to use security and so on. The code and Junit testcases already 
exist in the Riena CVS repository. We are just a little bit behind setting up the documentation.

Concerning persistence you might be interested in ObjectTransactions which deliver in milestone 2. They include some 
mechanim to track changes in large objectnets, transfer only the modified properties from the client back to the server 
and then allow either reconstructing the complete objectnet on the server or only change the modified properties in the 
server DB.

We had a presentation in the Eclipse Summit in October in Germany. There are some slide online available from that event
http://www.eclipsecon.org/summiteurope2007/index.php?page=detail/&id=37

We are also having a long talk slot on the EclipseCon 2008 in Santa Clara in march if you are coming
http://www.eclipsecon.org/2008/?page=sub/&id=150

There is also a rough plan for Riena
http://wiki.eclipse.org/Riena_Project#Riena_Project_Plan

which we will supply more details as we progress....

You are certainly welcome to try what is there or express requirements, use-cases, missing features etc.

regards
christian
