I could do it with MBean but, this code changes the server attribute (I mean, for all instances). Anyone know how to do it just for the current session?
// obtain the mbean server instance
MBeanServer server = (MBeanServer)MBeanServerFactory.findMBeanServer(null).iterator().next();
// construct target object name
ObjectName name = new ObjectName("jboss.varia:name=DataSourceDelegator");
// set attribute value
Attribute attr = new Attribute("TargetName", "java:/AnotherDS");
server.setAttribute(name, attr);

Subject: RE: [JBoss-dev] cmp with multiple datasource
I could do it work via jmx-console, but I cannot find the way to do it in my program. I'm doing:
DataSourceDelegator dsd = new DataSourceDelegator(); try{ dsd.create(); dsd.setBindName("java:/DS1"); dsd.setTargetName("java:/DS2"); } catch (Exception e) { System.out.println("..."); }
what is wrong in here?

It is checked in Branch_3_2. org.jboss.varia.dsdelegator package.
After building (varia/build.bat), you should find dsdelegator.jar in varia/output/lib. It should be copiied to server/<config-name>/lib.
In varia/src/resources/services/dsdelegator you can find a sample config dsdelegator-service.xml
Sorry, for the delay.

I went another way and wrote a datasource delegator service. It is very simple. The service implements DataSource interface and has a method that sets the target DataSource. The service is bound into the JNDI. All you need to do is just to specify this service instead of a real DataSource for your entity beans and change the target at runtime.
I could commit it in org.jboss.varia.* if there is an interest in it.

We could add support for chaging entity bean's datasource at runtime only in case when the datasources have the same type mappings (datasource-mapping) and database schemas are the same. Would it help you?

this is my scenario: we need to migrate an old application that have 5 different implementations, so when a user log into the application, it is
redirected
to his respective server. In each server is running the same data model
but
with different data.
Now, we are migrating this old app (client/server) to web but we cannot change the data model (damn customer issue), so I´m trying to not
construct
different EJBs to each datasource.
The meanwhile workaround is to create a new jar for each implementation
(the
same code, but with different jndi names and datasources), but it
represents
a heavy maintenance code...
Any ideas?

No way, at the moment. But could you tell why you would like to do it? Thanks.

Hi all,
does anybody know how can I change the CMP entity bean datasource on
runtime? Are there any workaround to get this?
