Instatiate an aggregate AE having reference to a UriSpecifier
Hi,
On our project we are currently trying to create OSGI Bundle to integrate UIMA components.
For the moment it works well but I have an instantiation problem using an aggregate AE which reference a Vinci descriptor.
He is what i'm doing:
-- Main descriptor of the aggregate AE (X.xml) --
<?xml version="1.0" encoding="UTF-8"?>
<taeDescription xmlns="http://uima.apache.org/resourceSpecifier">
<frameworkImplementation>org.apache.uima.java</frameworkImplementation>
<primitive>false</primitive>
<delegateAnalysisEngineSpecifiers>
<delegateAnalysisEngine key="A">
<import location="A.xml"/>
</delegateAnalysisEngine>
<delegateAnalysisEngine key="B">
<import location="B.xml"/>
</delegateAnalysisEngine>
</delegateAnalysisEngineSpecifiers>
<analysisEngineMetaData>
<name>XXX</name>
<description>slmkjhsqldkjfhldfjkh</description>
<version>1.0</version>
<vendor>XXX</vendor>
<configurationParameters/>
<configurationParameterSettings/>
<flowConstraints>
<fixedFlow>
<node>B</node>
<node>A</node>
</fixedFlow>
</flowConstraints>
<typePriorities/>
<fsIndexCollection/>
<capabilities>
<capability>
<inputs/>
<outputs/>
<languagesSupported/>
</capability>
</capabilities>
<operationalProperties>
<modifiesCas>true</modifiesCas>
<multipleDeploymentAllowed>true</multipleDeploymentAllowed>
<outputsNewCASes>false</outputsNewCASes>
</operationalProperties>
</analysisEngineMetaData>
<resourceManagerConfiguration/>
</taeDescription>
-- Descriptor B.xml describes a UriSpecifier --
<?xml version="1.0" encoding="UTF-8"?>
<uriSpecifier xmlns="http://uima.apache.org/resourceSpecifier">
<resourceType>AnalysisEngine</resourceType>
<uri>XXX</uri>
<protocol>Vinci</protocol>
</uriSpecifier>
Then in Java i'm using this code to instantiate the Aggregate AE (uimaComponentDescriptorPath is the path to the main component descriptor, uima) :
ConfigurationManager configurationManager = UIMAFramework.newConfigurationManager();
try
{
// uimaComponentDescriptorPath is the path to the main component descriptor of the aggregate (X.xml)
ResourceSpecifier uimaComponentDescription = UIMAFramework.getXMLParser().parseResourceSpecifier(new File(uimaComponentDescriptorPath));
// uimaComponentRootPath is the path to the root directory of the aggregate AE
ResourceManager resourceManager = UIMAFramework.newDefaultResourceManager();
resourceManager.setDataPath(uimaComponentRootPath);
// Component classPath is computed using an utility function
String uimaComponentClassPath = this.buildUimaComponentClassPath(uimaComponentRootPath);
resourceManager.setExtensionClassPath(this.getClass().getClassLoader(), uimaComponentClassPath, true);
AnalysisEngine analysisEngine = UIMAFramework.produceAnalysisEngine(this.uimaComponentDescription, resourceManager, null);
}
catch (Exception e)
{
}
The line AnalysisEngine analysisEngine = UIMAFramework.produceAnalysisEngine(this.uimaComponentDescription, resourceManager, null); throws an exception :
org.apache.uima.resource.ResourceInitializationException: The Resource Factory does not know how to create a resource of class org.apache.uima.analysis_engine.AnalysisEngine from the given ResourceSpecifier. (Descriptor: file:/D:/workspace_npf/component/desc/B.xml)
at org.apache.uima.UIMAFramework.produceResource(UIMAFramework.java:261)
at org.apache.uima.UIMAFramework.produceAnalysisEngine(UIMAFramework.java:352)

at org.apache.uima.UIMAFramework.produceResource(UIMAFramework.java:303)
at org.apache.uima.UIMAFramework.produceAnalysisEngine(UIMAFramework.java:383)
So this error indicate that UIMA can't find the a ResourceFactory to create an AnalysisEngine from a <uriSpecifier>....</uriSpecifier> descriptor.
What is the problem in the source code ? I think i've missed a step because this Aggregate AE is working in a CPE.
Thanks,
Baptiste Gaillard

RE: User configuration params in CPE descriptor
Posted by "Duan, Nick" <Ni...@ManTech.com>.
Marshall, I realized there wasn't any need for specifying additional
user parameters, as you indicated, there isn't any coding required for
modifying CPE at the manager level. Please consider the matter as
closed.
Thanks!
Nick

I don't think I quite understand what you're asking for. The CPE
descriptor has a place for specifying user-defined parameters, within
each component (which you may be acknowledging with your parenthesized
remark). If you''re asking about other user-defined parameters - what
would be "user" of these? (There's no user-written code other than what
is in the components.)
Please say more details if this doesn't address your question. -Marshall

I now see another thread has picked up on this. Let's keep the
discussion (if there is anymore) on the other thread.

User configuration params in CPE descriptor

Is there any way to specify a user-defined parameter in CPE descriptor
(like what you can do in CPE components' descriptors)?
Thanks!

I suggest checking to make sure that uima_adapter_vinci.jar is in your
classpath. Usually that's the cause of this error message.
