Lucas compile error

[Roland Cornelissen <ro...@kabelco.nl>]

Hi,
I try to get LUCAS to work for me in Eclipse but I keep remaining this 
error for SplitterFile.java in org.apache.uima.lucas.indexer.analysis: 
splitIterator = Iterators.forArray(splitts, 0, splitts.length);
The error I get is: Type mismatch: cannot convert from 
UnmodifiableIterator<Serializable> to Iterator<String>

With this error Lucas seems to work, it produces an index, but I'm not 
certain if that will be so all the time.

I used the following libraries: Lucene 2.4 
(core,highlighter,memory,snowball) / Google Collect 1.0 /Uima 

Can anybody explain what's going on here??

Roland

Thanks for the fast reply Marshall,

The classpath was correct but referenced to Google-collect-1.0.jar , 
which seems to be an incompatible version.

When including Google-collect-0.9.jar the error was gone. 

tnx

Perhaps the classpath is not correct?  The line

splitIterator = Iterators.forArray(splitts, 0, splitts.length);


on my setup shows Iterators.forArray returning a type of
UnmodifiableIterator<String>, not UnmodifiableIterator<Serializable>

The implementations of Iterators is coming google collections 0.9 jar. 
Where is your implementation coming from?  (To see this in Eclipse, you
can do the following:
  1) press pf3 after putting your cursor on the word Iterators in the
above line of code
  2) press the "link with editor" button (icon is a left arrow over a
right arrow) on the Package Explorer window set of buttons at the top of
this view (if it is not already pushed in - it's a toggle), and that
should switch the package view to the source file location.  In my setup
it goes to Referenced Libraries - google-collections-0.9.jar.
