Dynamic JCo Connection with Adaptive RFC Model 2

Question

Hi gurus,
I'm trying to dinamically change a model data connector inside my web dynpro. I'm using an Adaptive RFC Model 2 to communicate with the R/3 backend. I've found that is possible to change the connector modifiyng the code inside the web dynpro. In detail I've found this example:
IWDDynamicRFCModel model1 = (IWDDynamicRFCModel) WDModelFactory.getModelInstance(Model1.class);
I put this code into wdDoInit method but I get the following error:
"<comp_name>.wdDoInit failed to create or init instance of model 'model_name' in scope NO_SCOPE with instanceId 'null'"
Furthermore I've used the deprecated Adaptive RFC Model and when I instantiate a model, ModelName m=new ModelName(), I see that the methods m.setJcoClient(client) and m.setSystemName(systemName) are visible, while when I try to do the same with Adaptive RFC Model 2, with my model m, the methods before there aren't.
So this is my question: is it possible to change data connector dinamically with Adaptive RFC Model 2?
Thanks a lot

Dear Lukinho,
You may try this ;
try {
IWDJCOClientConnection clientCon =  WDSystemLandscape.getJCOClientConnection("<name of the JCO connection>");
String clientName      = clientCon.getClientName();
String lang          = clientCon.getLanguage();
String passowrd          = clientCon.getPassword();
String sysID          = clientCon.getSystemIdentifier();
String user          = clientCon.getUser();
//etc...
} catch (WDSystemLandscapeException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
I got this code from the thread   [Multiple Client Logon in JCO   |Re: Multiple Client Logon in JCO;
Also have a look at this thread
[JCo Destination   |Re: JCo Destination;
Hope it helps!!
