Re: model file problen in opennlp uima wrapper
Thanks! Indeed either OpenNLP or uima wrapper needs to be compiled with Java 1.6. I will check out the wrappers. I didn't figure out the cvs-root name and project name on the sourcfourge site. I assumed /opennlp and opennlp.uima but the cvs command didn't work. cvs -d:pserver:anonym...@opennlp.cvs.sourcefource:/opennlp checkout opennlp.uima Any ideas?

Re: model file problen in opennlp uima wrapper
I would hope that Java is backward compatible, so you should only need to run with a JDK that is = the one(s) used to compile your code. Burn.

model file problen in opennlp uima wrapper
Hello, I was trying to run the OpenNLP UIMA wrapper OpenNLPAggregate.xml from the UIMA examples (org.apache.uima.examples.opennlp.annotators) and load it in the CAS Visual Debugger. I got the following Java exception: Exception in thread AWT-EventQueue-0 java.lang.UnsupportedClassVersionError: Bad version number in .class file at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:675) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$100(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:316) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java: 280) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java: 374) at org .apache .uima .examples .opennlp.annotator.SentenceDetector.initialize(SentenceDetector.java:54) ... at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:176) at java.awt.EventDispatchThread.run(EventDispatchThread.java: 110) The Java source code of this line is when the Wrapper initializes the OpenNLP Sentence Detector: sentenceDetector = new opennlp.tools.lang.english.SentenceDetector(modelFile); I did the following steps. 1) Create a new Java project with UIMA nature. 2) Add necessary libraries (uima core, opennlp, etc.) and descriptors (Aggregate Engine and it's dependent Annotators) 3) set the ModeFile parameter Configuration Parameters in the Analysis Engine XML files (OpenNLPSentenceDetec, OpenNLPTokenizer, OpenNLPTagger) to the absolute path of the corresponding model file (e.g. /home/workspace/models/model.bin.gz). I also tried relative paths. 4) Open the CAS Visual Debugger and Load the Aggregate Engine 5) Java Error when trying to load the model file: UnsupportedClassVersionError Error Maybe the model file was be loaded successfully. I do get the same error message when the model file in SentenceDetector is empty. For any help I would be grateful. Regards, Toby
Re: model file problen in opennlp uima wrapper
That probably means the OpenNLP library was compiler with a newer version of Java. Try switching to a higher version number. (The message usually indicates the version number, e.g. 6 for Java 1.6) Burn.
Re: model file problen in opennlp uima wrapper
It may be worth pointing out that there is a very nice set of uima wrappers for OpenNLP available from their sourceforge cvs repository. See http://opennlp.cvs.sourceforge.net/opennlp/. While this is still a work in progress - it is *much* nicer than the example wrappers that ship with UIMA.
