Cheers all.
Just some notes:
1) Andrew, I think you have misread what I asked. Yes, I pointed you
@ some constructors. What you were supposed to be noting was that
those constructors require arguments of type Field.Index, Field.Store,
Field.TermVector, which are inner classes. Make sense now?
2) Grant's example doesn't work (in case anyone else was tempted to
run with it). One's never going to get very far trying to instantiate
a Java object as a "component" (I presume that's just a brain-fart,
though), but more importantly the class-reference syntax seems wrong.
Or at least it is at odds with what a few other people have come up
with, and indeed it just errors.
3) MrBuzzy: cheers, that's it. The Adobe article is, however, a bit
misleading in saying this: "You cannot call Java inner classes
directly in ColdFusion". Because, as MrBuzzy demonstrates, you can.
4) Using MrBuzzy's syntax, I see what Grant is talking about: despite
creating the objects just fine, the constructor code just errors with
- rather unhelpfully - " An exception occurred when instantiating a
java object. The cause of this exception was that: ." back from CF.
Accessing the objects in isolation works fine, but CF is buggering
something up between instantiation and using them in the constructor.
EG:
<cfset oIndex = createobject("java","org.apache.lucene.document.Field
$Index")> <!--- works fine --->
<cfset oIndexNo = oIndex.NO> <!--- works fine --->
<cfdump var="#oIndexNo#"> <!--- works fine, and outputs what I'd
expect to see --->
<cfset oStoreNo = createobject("java","org.apache.lucene.document.Field
$Store").NO> <!--- works fine --->
<cfdump var="#oStoreNo#"> <!--- works fine --->
<cfset oDoc.add(oField.init("id", "1", oStoreNo, oIndexNo))> <!---
errors as per above--->
NB: using the Field(String name, Reader reader) constructor works
fine, but I don't want to do that.
I've yet to finish exploring this, though, and if I nut it out, I'll
pass it on.
I am leaning towards Grant's / MrBuzzy's suggestions of wrapping this
stuff in a quick Java class, written in such a way that the methods
only expect data types CF is comfortable with.
All interesting stuff.
Cheers again.
