Hi,
is it possible to use primitive data types as method parameter
in ECF?
Currently...for remote services and the ECF generic provider...no.
Since 1.4 (or some earlier version...I can't remember exactly) Java
does autoboxing of primitive data types, and this complicates things
tremendously for the remote services use case.
Its possible that autoboxing could be worked around...contributions
welcomed as always.

It seems to me that the deserialization of the
shared message objects doesn't work correctly. A
java.lang.NoSuchMethodException is always thrown, because ECF
is trying to find a method with "class java.lang.Integer" as
parameter data type instead of the primitive int data type. I
wrote a little example application:
Interface:
public interface Test {
void doSomething(int pBla);
}
Server:
public void start(BundleContext bundleContext) throws
Exception {
Activator.context = bundleContext;
Properties props = new Properties();
props.put("service.exported.interfaces", "*");
context.registerService(Test.class.getName(), new
Test() {
@Override
public void doSomething(int pBla) {
}
}, props);
}
Client:
Test t = (Test) getContext().getService(reference);
t.doSomething(42);
Throws:
java.lang.NoSuchMethodException: No such method:
doSomething([class java.lang.Integer])
