             Summary: Specifying other classes, such as FileResourceSpecifier_impl, as resource specifiers causes IllegalClassException when binding
                 Key: UIMA-3093
                 URL: https://issues.apache.org/jira/browse/UIMA-3093
             Project: UIMA
          Issue Type: Bug
          Components: uimaFIT
            Reporter: Richard Eckart de Castilho
            Assignee: Richard Eckart de Castilho
             Fix For: 2.0.0uimaFIT


I'm working with ConceptMapper, which means I need to attach a FileResourceSpecifier to the external dictionary resource (it only took me most of the day to work this out).

The relevant bits of code are something like this:


AnalysisEngineDescription aed = AnalysisEngineFactory.createAnalysisEngineDescription(
    "analysis_engine.descriptor_name");
ExternalResourceDescription dictRes = 
    ExternalResourceFactory.createExternalResourceDescription(
    "DictionaryFileName", DictionaryResource_impl.class, "someURL");
FileResourceSpecifier frSpec = new FileResourceSpecifier_impl();
frSpec.setFileUrl("file:testDict.xml");
dictRes.setResourceSpecifier(frSpec);
ExternalResourceFactory.bindExternalResource(aed, 
    ConceptMapper.PARAM_DICT_FILE, dictRes)

This gets an IllegalClassException:

org.apache.commons.lang.IllegalClassException: Unsupported resource specifier class [class org.apache.uima.resource.impl.FileResourceSpecifier_impl]
	at org.uimafit.factory.ConfigurationParameterFactory.canParameterBeSet(ConfigurationParameterFactory.java:584)
	at org.uimafit.factory.ExternalResourceFactory.bindNestedResources(ExternalResourceFactory.java:839)

I think this is a spurious error; I've wrapper the call to .canParameterBeSet() in a try/catch, and it seems to work fine (I've now got another unrelated downstream problem, so I can't promise yet, but will update when I do know more)
