Hi Dimitris,
I use my campus' internet connection that must use proxy. So, i must configure
it in extraction-framework/dump/pom.xml.
I configure it like this,
<launcher>
<id>extraction</id>
<mainClass>org.dbpedia.extraction.dump.extract.Extraction</mainClass>
<jvmArgs>
<jvmArg>-server</jvmArg>
<jvmArg>-Xmx1024m</jvmArg>
<jvmArg>-Dhttp.proxyHost=152.118.24.10</jvmArg>
<jvmArg>-Dhttp.proxyPort=8080</jvmArg>
<jvmArg>-Dhttp.nonProxyHosts="localhost|152.118.*.*|*.ui.ac.id"</jvmArg>
</jvmArgs>
</launcher>
Before I solved this problem, I found some kind of message error :
- java.net.ConnectException: Connection timed out
- java.net.SocketException: Invalid argument or cannot assign requested address
- java.net.UnknownHostException: www.w3.org
- java.lang.Exception: Could not retrieve abstract for page: title=Daftar
filsuf;ns=0/Main/;language:wiki=id,locale=in
I have sent pull request.
Thank you Dimitris and Jona
Regards,
Riko

Judul: Re: [Dbpedia-discussion] Abstract extraction problem
Hi Riko,
We had similar (proxy) problems in the past but we didn't documented them
anywhere.Would you mind writing how you bypassed the proxy issue?
You could make a pull request with your proxy-pom configuration (as a comment)
and drop a couple of lines explaining it here:
https://github.com/dbpedia/extraction-framework/wiki/Extraction-Instructions
And of course, you can also add everything that you had to figure out on your
own:)
Thanks
Dimitris
