Hi all,
I have a problem when I am trying to use AbstractExtractor. I have done the
instructions from [1] to make local mediawiki instance. Then, I tested local
mediawiki instance like this :
http://localhost/mw-modified/api.php?uselang=id&action=parse&text=[[This]]%20is%20a%20[[Test_text|text%20for%20testing]]
the result :
<?xml version="1.0"?> <api> <parse> <text xml:space="preserve">This is a text
for testing</text> </parse> </api>
I think there are no problem with my local mediawiki instance, but some problem
appear when I am running AbstractExtractor.
I replaced this line
privatevalapiUrl="http://localhost/mediawiki/api.php";
with
privatevalapiUrl="http://localhost/mw-modified/api.php";
Example the error:

Any idea how to fix this problem ? Thank you !
