I looked at SeamTest and felt kind of silly for not putting any of the test
logic in a script. I changed it thusly:
| public class GreeterTest extends SeamTest {
|
| @Test
| public void testGreeterHello() throws Exception {
| new Script() {
| @Override
| protected void invokeApplication() {
| Greeter g = (Greeter)
Component.getInstance("greeter");
|
| assert "Hello, world!".equals(g.getHello());
| }
| }.run();
| }
| }
|
And at least I got a more familiar error.

I've always wondered at the generality of "could not instantiate Seam
component". Why not? Was the underlying class not found? Name not resolved?
Bad Mood? Stars not in alignment? Doesn't seem to be name related, because
when I try Component.getInstance("kwyjibo") I get the ubuquitous
NullPointerException instead (Java seems to give me more of those than I ever
got in C or C++)
