Hi,
so I've come a bit further now. Still generated the proxies with Ant upfront.
When I used a ClientSideClassFactory then I got a
IlleagalArgumentException in the constructor of the generated proxy class
AltrimiGenerated*_Main.java.
When I swiched back to ServerSideClassFactory as in this code snipplet
try {
HostContext hc = new SocketObjectStreamHostContext(host, port);
Factory factory = new ServerSideClassFactory(false);
factory.setHostContext(hc);
datasource = (SIMONDataSource)factory.lookup("server");
assertNotNull(datasource);
} catch (ConnectionException e)
{
fail("Cannot get datasource component");
}
I got the component so the lookup was successful now, but then this
exception:

And about exceptions, exceptions are also serialized to the client side?
Could I create a interface and a proxy for a exception class if I don't
want a certain exception to be serialized to the client side due to JNI
for example?
Then finally there are various host context classes, which ones are most
preferable, stable and fully functional? Can anybody give some overview or
advice on which to take? I just looked in the examples and took the
SocketObjectStreamHostContext but some examples use s
CustomSocketObjectStreamHostContext and others.
Regards, Peter
