Hi,
I did some further testing and the problem seems to happen when the FS is not
declared in the remote C++ TAE but declared and set in an AE in the (lokal) main
application (in out case a CPE running various Java AEs).
In my unit test I create a "DummyAE" descriptor basically doing nothing but
declaring a "DocumentData" type with the URL Feature. I also created a
customResourceSpecifier pointing to the DAVEDETECTORQ on the remote system. My
test looks like this:
public class RemoteCTaeTest {
private AnalysisEngine daveAe;
private AnalysisEngine myAe;
/**
* @throws java.lang.Exception
*/
@Before
public void setUp() throws Exception {
URL daveResource =
RemoteCTaeTest.class.getClassLoader().getResource("DaveResource.xml");
URL myResource =
RemoteCTaeTest.class.getClassLoader().getResource("DummyAE.xml");
ResourceSpecifier res =
UIMAFramework.getXMLParser().parseResourceSpecifier(
new XMLInputSource(daveResource));
AnalysisEngineDescription aeDesc =
UIMAFramework.getXMLParser().parseAnalysisEngineDescription(
new XMLInputSource(myResource));
this.daveAe = UIMAFramework.produceAnalysisEngine(res);
this.myAe = UIMAFramework.produceAnalysisEngine(aeDesc);
}
/**
* @throws Exception
*/
@Test
public void testSendCAS() throws Exception {
CAS cas = CasCreationUtils.createCas(Arrays.asList(new
AnalysisEngineMetaData[] {
this.daveAe.getAnalysisEngineMetaData(),
this.myAe.getAnalysisEngineMetaData() }));
JCas cas2 = cas.getJCas();
DocumentData metadata = new DocumentData(cas2);
metadata.setDocumentURL("http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1";);
String text = "This is a Dave Test.";
cas2.setDocumentText(text);
cas2.addFsToIndexes(metadata);
this.daveAe.process(cas2);
System.out.print(cas2.getJFSIndexRepository().getAllIndexedFS(DocumentData.type).next());
}
}
The test fails when I used the DaveDetector descriptor delivered with
"2.2.2-incubating". When I add DocumentData type to the DaveDetector descriptor,
the test succeeds and the URL is returned correctly by the remote AE:
(../examples/descriptors/DaveDetector.xml)

</featureDescription>

</typeDescription>

</typeSystemDescription>
I will attach both descriptors used in the test. The implementation of the
DummyAE is completely empty, since it is not called in the test.
From my UIMA understanding so far a remote AS service shouldn't have to declare
or import all types and type systems by potential AE clients connecting to it,
or am I wrong in this regard?
I attached the descriptors used in the Junit test above. Hope this helps. I will
continue to try to reproduce the problem using CVD.

Hi,
Well, I tried another, simpler scenario based on your description:
Just add the following to DaveDetector.xml:
<typeDescription>
<name>uima.tcas.Chris</name>
<description></description>
<supertypeName>uima.tcas.Annotation</supertypeName>
<features>
<featureDescription>
<name>documentURL</name>
<description></description>
<rangeTypeName>uima.cas.String</rangeTypeName>
</featureDescription>
</features>
</typeDescription>
Create the following CasXmi file:
<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:cas="http:///uima/cas.ecore";
xmlns:tcas="http:///uima/tcas.ecore";
xmlns:xmi="http://www.omg.org/XMI"; xmi:version="2.0">
<cas:NULL xmi:id="0"/>
<cas:Sofa xmi:id="1" sofaNum="1" sofaID="_InitialView"
mimeType="text" sofaString="This is a text document with Dave for
analysis"/>
<tcas:DocumentAnnotation xmi:id="8" sofa="1" begin="0" end="46" language=""/>
<tcas:Chris xmi:id="20" sofa="1" begin="0" end="1"
documentURL="http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1"/>
<cas:View sofa="1" members="8 20"/>
</xmi:XMI>
Launch the unaltered DaveDetector as a service, have CVD connect to it
via JMS service descriptor, use File->Read Xmi Cas File to load the test Cas,
use Run->Run DaveDetector On CAS to call the remote service, and, finally
expand the annotation index to see the results. No problems.
This was using something close to uima-2.3.0.

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
