>From the above information what seems to be happening is that a request for the establishment of a component of the type x.y.z.SomeServiceImpl.class is being made but when the container attempt to get the Type definition there isn't one. This means that during the initial model construction phase the process of scanning the jar files in the block classpath did not result in the discovery of a resource named /x/y/z/SomeServiceImpl.xinfo - or, it was discovered by the corresponding class was not loadable. In the second case you would get a warning message saying that the component type was ignored and the reason why. Another way to isolate the problem is to turn on -debug mode and following through the messages during the scanning phase to see what is happening (or not happening). It would also be interesting to know if you have the same problem when running your component under Metro.
