Hey rjcarr!!! Thanks for ur answer!
At the end, I found my problem: it was because of the Google App
Engine - 1.3.0. Can I tell u a little bit deeper?? (my curiosity is
killing me softly...)
In my server package I have a class called "Indexer". Inside of this
class, a line just calls a value:
MaxFieldLength lim = IndexWriter.MaxFieldLength.LIMITED,
needed to call the indexer function, but throws a
NoDefClassException:
... index() threw an unexpected exception:
java.lang.NoClassDefFoundError: org/apache/lucene/index/IndexWriter
$MaxFieldLength
I don't know if that '$' wants to tell me something and I'm not being
able to hear it! Others unexpected exceptions are thrown, such as
java.lang.NoClassDefFoundError: org/apache/lucene/store/Directory, and
more, always "NoClassDefFoundError" exceptions, although all jar's
needed are imported and the compilation runs perfectly.
Have u got any idea about why am I getting these messages, these
exceptions?? AH!! I was forgetting it: the first message I get trying
to index the files is an "Exception while dispatching incoming RPC
call", but if I comment the rest of the lines and write a simple
System.out.println("HI THERE"), there's no exception.
It seems as if it couldn't resolve the Lucene classes and methods...
but why just with the Google App Engine?? If I create a new project,
and I don't select the "Use Google App Engine", problems disappear...
Thank u very very much... all the weekend trying to catch the solution
and no solution found is very frustrating...
cheers!!
