Re: strange interop behaviour/issue
Ok I investigated a bit further and I found some seriously weird
stuff...I'm gonna need the help of a java expert here:
(pprint (.getMethods (.getClass opennlp-pos))) ;;notice that the method
I'm trying to call *doesn't exist according to this*
[#Method public static opennlp.tools.postag.POSModel
opennlp.tools.postag.POSTaggerME.train(java.lang.String,opennlp.tools.util.ObjectStream,opennlp.tools.util.model.ModelType,opennlp.tools.postag.POSDictionary,opennlp.tools.dictionary.Dictionary,int,int)
throws java.io.IOException,

nil
but then this seems very strange so I went and decompiled the class file
(actually the entire jar) and the method that takes 2 arrays as args
does exist both in the interface and the concrete implementation
(POSTagger POSTaggerME respectively)
how on earth can that be? any ideas anyone? this seems utterly odd to me!

Hi all,
I came back to a project of mine after a week or so and I'm facing a
problem which I have no idea where it came from! This is the first
time I'm seeing it on this project - everything worked just fine a
week ago! The problem is this:
Consider some java class (opennlp-POS-tagger) with 3 .tag()
overloads...signatures and bodies follow:
public *String[] tag(String[] sentence)* {
return this.tag(sentence, null); //this is essentially what I'm
trying in my code
}
public *String[] tag(String[] sentence, Object[] additionaContext) *{
bestSequence = beam.bestSequence(sentence, additionaContext);
ListString t = bestSequence.getOutcomes();
return t.toArray(new String[t.size()]);
}
public *String[][] tag(int numTaggings, String[] sentence) *{
Sequence[] bestSequences = beam.bestSequences(numTaggings,
sentence,null);
String[][] tags = new String[bestSequences.length][];
for (int si=0;sitags.length;si++) {
ListString t = bestSequences[si].getOutcomes();
tags[si] = t.toArray(new String[t.size()]);
}
Now, from my code I'm trying to do:
(.tag opennlp-pos (into-array [New-York (NY) is the city
that never sleeps .]) nil)
which gives me a IllegalArgumentException Unexpected param type,
expected: int, given: [Ljava.lang.String;
clojure.lang.Reflector.boxArg (Reflector.java:432)
Basically, it's trying to invoke the last overload ,whereas I'm trying
to invoke the second one!!!
If I omit the 'nil' at the end , the correct method is invoked (the
first which calls the second)...why can't Clojure find the second
overload and goes for the 3rd?
any ideas?
Jim

What explains the occurrence of these extra signatures that you don't mention above? It's hard to answer without having the full picture.

Re: strange interop behaviour/issue
It looks like: public String[] tag(String[] sentence, Object[] additionaContext); wasn't originally present in the API, and was added in: http://svn.apache.org/viewvc/opennlp/trunk/opennlp-tools/src/main/java/opennlp/tools/postag/POSTaggerME.java?r1=1245855r2=1294177 It sounds like you might have more than one version of the class on your classpath perhaps, or at least aren't using the code you think you're using?

Re: strange interop behaviour/issue
that is a reasonable thought indeed but it is extremely unlikely that something like this is happening...the version of opennlp I'm using is my own home-brewed one which I've manually installed in my local-repo for sometime now...in my project.clj the dependency looks like this: [experiment/experiment 1.5.3] the source of that jar is still on my eclipse workspace which I can consult very quickly...in addition I threw the jar in the JD decompiler and after poking around I did find the methods... however some other lib may be pulling in openNLP...give me 2 sec I'll get back to you...

Re: strange interop behaviour/issue
David you are a genious!!! thank you thank you very much!!! one of my dependencies was pulling in opennlp/tools 1.5.0 which is a 2 year old jar!!! added :exclusions and now I'm back in the game If you're in Manchester Uk I'm buying beer... :) Jim On 12/03/13 14:49, David Powell wrote: It looks like: public String[] tag(String[] sentence, Object[] additionaContext); wasn't originally present in the API, and was added in: http://svn.apache.org/viewvc/opennlp/trunk/opennlp-tools/src/main/java/opennlp/tools/postag/POSTaggerME.java?r1=1245855r2=1294177 It sounds like you might have more than one version of the class on your classpath perhaps, or at least aren't using the code you think you're using?
