Hello Hugo,
the resource is not stored in the resource manager under the name that you
specify, but under a "qualified name" that consists of the qualified context
name and the resource key to which the resource is bound.
The proper way to access the resource after the execution would be through the
UIMAContext of the AE, e.g.
AnalysisEngine ae = createEngine(
DummyAE3.class,
DummyAE3.RES_KEY_1, createExternalResourceDescription(
"lala", AnnotatedResource.class,
AnnotatedResource.PARAM_VALUE, "1"));
... = ae.getUimaContext().getResourceObject(DummyAE3.RES_KEY_1);
The alternative would be to manually construct the qualified name, which then
would go like this:
... = ae.getResourceManager().getResource(
ae.getUimaContextAdmin().getQualifiedContextName() +
DummyAE3.RES_KEY_1);
Sure, uimaFIT ( mind capitalization ;) ) does hide a lot of the details -
that's the point!
But the names under which resources are stored in the resource manager is
determined by the UIMA core:
The ResourceManager_Impl has multiple internal lookup tables. The one used for
getResource() uses these qualified names and a resource can appear in there
multiple times, bound to multiple qualified names (multiple AEs). There is
another lookp table called mInternalResourceRegistrationMap in which each
resource appears only once under the name that you can optionally specify in
the createExternalResourceDescription call (here "lala"). However, that table
is very unfortunately not accessible.
Cheers,
