Whirlwind Demo GUI : java.lang.NullPointerException at com.wwm.util.FileUtils.readObjectFromGZip

[agelos.pikoulas]

Hi to all,

Just learned about fuzzydb and decided to have a look. I followed the
instructions on https://github.com/whirlwind-match/whirlwind-db. On
the GUI when pressing "Random entries" I have the following.
I am guessing some zip file is missing from the git "master", I found
none under the filesystem.

Regards

Hi,

Good to hear you're interested in fuzzy matching.

You're right about the missing file. There's a larger optional
dataset we've used in-house that should not be needed.

I've got a fix sorted and pushed to github. Let me know if you have
any more problems.

We'd also love to hear what you're looking at doing with the
database. We could do with real world examples for sample
applications :)

All the best,

Neale

Hi Neale and thanks for your response,

I am evaluating various web 3.0 technologies for a pet project that I
have - scoring and fuzzy searching is one of my requirements, so I
would like to evaluate your offering.

It now complains about y:\apps\wwm-postcode\randomPostcodes being
missing.
Do I need to copy some file somewhere ?

Hi,

It sounds like either you don't have the full update, or that you didn't
mvn install everything.

I'd suggest:

git pull
mvn install -Pfast

mvn exec:java -pl com.wwm.indexer.gui

I've just done the following on Ubuntu 10.10:

git clone git://github.com/whirlwind-match/whirlwind-db.git
cd whirlwind-db/
sudo apt-get install maven2
sudo apt-get install openjdk-6-jdk
mvn install -Pfast

mvn exec:java -pl com.wwm.indexer.gui

And I have it working :)
