UIMA AS Client
Hi,
I am modifying RunRemoteAsyncAE.java. What I'd like to do is to make an
annotation in the Cas.
In the case of an empty Cas:
CAS cas = uimaEEEngine.getCAS();
I want to send a default text:
cas.setDocumentText("Some text to send to AS service.");
and create an annotation:
MyAnnotation ma = new MyAnnotation(cas.getJCas());
But I get "JCas type "MyAnnotation" used in Java code, but was not
declared in the XML type descriptor"
The Java implementation of the annotation is found, as it is defined,
but as it isn't a UIMA Analisys Engine, it hasn't access to the type
system of the pipeline.
How should I solve this issue?
Regards,
David

Weeird ... I added much the same to runRemoteAsyncAE
Iterator it = cas.getTypeSystem().getTypeIterator();
while(it.hasNext()) {
System.out.println(">>> Type: " + ((Type)it.next()).getName());
}
and as well as the uima types got types from my service, e.g.:
>>> Type: org.gale.Sentence
Did you see your types in the metadata returned in the log? Did the status
callbacks show that initialization was successful?

Hi,
we have tested our UIMA AS client with the RoomNumberAnnotator from UIMA
AS examples and, in this particular case, the UIMA AS client retrieves
the proper typeSystem.
When it has to do with our UIMA AS pipeline, the UIMA AS client only
retrieves the default UIMA type system, not the one from the AS service.
Our UIMA AS service has been tested through CVD and it seems right.
We have pasted the code of our client here: http://pastebin.com/zrSeMZe8

David

Can you deploy RoomNumberAnnotator from UIMA AS examples and connect your
client to it to see if you get service types. You should see
type: org.apache.uima.tutorial.RoomNumber.
The example is in
UIMA_HOME/examples/deploy/as/Deploy_RoomNumberAnnotator.xml. Queue
name: RoomNumberAnnotatorQueue

Ok, we do obtain an XML with <analysisEngineMetaData> that contains the
full type system. It also shows up correctly in the CVD.
However, when trying to get the type system from a Java client, we only
get the default UIMA type system, not the one from the AS service.
We initialize a UimaAsynchronousEngine and then call .getCAS() on it to
obtain an empty CAS and .getTypeSystem() on that CAS. Getting all types
via .getTypeIterator() shows only the base UIMA types. Our
understanding was that the CAS obtained from the UimaAsynchronousEngine
would have the AS service's type system.

To see what typesystem is returned by your service you can turn up the
logging when invoking runRemoteAsyncAE.
In your UIMA_LOGGER_CONFIG_FILE set
org.apache.uima.adapter.jms.client.level = FINEST
and you'll see the service's typesystem as part of the metadata returned to
the client.

UIMA doesn't allow defining types in aggregate descriptors. There
should be an error in the uima.log for the service. If not, there were
bugs in uima-as 2.3.0 that lost the root cause of exceptions in
uima core components. Running that aggregate with cvd should
show the error. CVD also allows one to browse the type system.

Thanks, is there a way to check what type system the AS service uses?
MyAnnotation is declared in the capabilities section of the aggregate
descriptor of the service (AS primitive, made from merging a few PEARS).
The type system itself (its XML definition) is imported in the
separate AE descriptors, which works without problems in other settings
(e.g. deploying the aggregate PEAR through SimpleServer).

When the UIMA AS Client is initialized the type system for its casPool
comes from that of the remote service, optionally merged with that of
the registered collection reader if there is one. MyAnnotation will
have to be defined in one of those two to be in the CAS definition.
