Hi Eddie,
unfortunately I'm out of the office today so I can only send you the unit test
reproducing the problem on monday. But our scenario is more or less the following:
- A CPE running several Java AEs first, then send the CAS to a remote AS Service
which is a C++ AE
- the collection reader adds a FS with document metadata (including the String
Feature "URL") to the CAS. This FS directly extends the Top-Type, not Annotation.
- I used the unaltered DaveDetector to replace our own C++ AE to reproduce the
problem
For the unit test I wrote a "No-OP" Java AE which uses a Typesystem only
including this "DocumentData" FS with only this one String Feature. I used a
Custom Resource Specifier like in the AS Documentation to reference the
DaveDetector on a remote machine. I then create a CAS using the CasCreationUtil
which in turn uses the "No-OP" AE descriptor and the DaveDetector-Resource
Specifier. I then add the problematic Feature in question and call "process" on
the remote Dave-AE. Then the exception I mentioned in my earlier mail happens.
I will send you the test code on monday and also try to use CVD to reproduce the
problem.
Thanks,
Christoph

Hi Christoph,
I could not reproduce the problem, with 2.2.2 or the latest 2.3.0
release candidate code.
My scenario was:
1. add the following feature to type David:
<featureDescription>
<name>documentURL</name>
<description></description>
<rangeTypeName>uima.cas.String</rangeTypeName>
</featureDescription>
2. add this code to DaveDetector.cpp:
AnnotationFS fsNewExp =
tcas.createAnnotation(david, uiExprBeginPos, uiExprEndPos);
+ Feature documentURL = david.getFeatureByBaseName("documentURL");
+ fsNewExp.setStringValue(documentURL,
"http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1";);
indexRep.addFS(fsNewExp);
3. start DaveDetector as a service:
deployCppService descriptors\DaveDetector.xml DaveDetector
4. create a DaveDetector JMS service descriptor pointing at the service:
<customResourceSpecifier xmlns="http://uima.apache.org/resourceSpecifier";>
<resourceClassName>org.apache.uima.aae.jms_adapter.JmsAnalysisEngineServiceAdapter</resourceClassName>
<parameters>
<parameter name="brokerURL" value="tcp://localhost:61616"/>
<parameter name="endpoint" value="DaveDetector"/>
</parameters>
</customResourceSpecifier>
5. use cvd to connect to the service, put a Dave and David in the
text, call it, and inspect the results.
Please do provide the modifications to DaveDetector and a details
description of the scenario.
Regards,
Eddie
