Hello,
I am currently building a web application (with SpringMVC running in
tomcat) that should serve to demonstrate the result of the processing of
each component in this pipeline. Some components do their job, while
others don't.
These are the facts:
- I am using one TypeSystem that is in the classpath of the main
application (as a jar).
- Each PEAR component has a type system descriptor, that reside in the
'desc' folder and are referenced by the AnalysisEngine descriptors. The
type system descriptors are all the identical.
- The component that does not work (a NETagger) uses another component
(utilities) - while the other working components don't (!!!) - for
getting a special Annotation object (type 'Variation' - a bio entity).
The call is:
entity = (Entity) AnnotationTools.getAnnotationByName(aJCas, className).
This call gives back null, and throws a
java.lang.reflect.InvocationTargetException caused by a
org.apache.uima.cas.CASRuntimeException: JCas type
"de.julielab.jules.types.Variation" used in Java code, but was not
declared in the XML type descriptor.
- I checked if the descriptors are missing that type, but they don't, so
I assume that the descriptors themselves are OK. Perhaps they have a
wrong place - but how do I see which descriptor UIMA uses at a time?
- I am installing the PEARs at runtime with the
PackageInstaller.installPackage(...) method
- The utilities are included in the main application as a jar; they
don't have any type system descriptors, because they should be used
independently and they are working in a 'non-PEAR' environement.
-can this have to do something with running it with tomcat?
I already recognized that each PEAR is loaded by a different classloader
and that this caused that the PEARs itself could not use its own
TypeSystem-JAR or other JARs that has dublicates in other PEARs or the
main application (e.g. log4j) - this is some kind of mysterious for me -
could someone explain why this is so?
So what can I do to get my NETagger running? Could anybody help me.
Hints and tips are also very welcome. (I'm getting frustrated with this
f... problem)
I attached a part of the tomcat logging file that shows the stacktrace
in detail when the above mentiond Exception is thrown.
greetings
Matthias
