Re: Maven Build Error

[Fan Yang]

Hi Dr. Adina, I named my $RDF_DATA file as ntriplesFile and put it under the folder same as Java code’s. I tried to delete the empty loadrdf file and re-run the code, the same error message was showed up. The error log containing the command I’m using, loadrdf java code and ntripleFile are attached in this email. Thanks! Bests, Fan

Cause when the war package is deployed, there is no such file named loadrdf under the certain folder. The n-Triples file I’m using is the one listed on the tutorial, the content is : <http://mynamespace/ProductType1> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://mynamespace/ProductType> . <http://mynamespace/ProductType1> <http://www.w3.org/2000/01/rdf-schema#label> "Thing" . <http://mynamespace/ProductType1> <http://purl.org/dc/elements/1.1/publisher> <http://mynamespace/Publisher1> .

Maybe that causes the error. Could you check your webapps directory to see if those files contain some certain scripts? Thank you so much!

Everything is working except loading data part. Even I fixed the “/“ error in the code I still face the same HTTP 500 error. I capture the error message when I load the link [4] http://localhost:8080/web.rya/loadrdf?format=N-Triples <http://localhost:8080/web.rya/loadrdf?format=N-Triples> on my browser and copy the tomcat log file to you. > > Bests, > > Fan > > <catalina.2015-12-03.log> > <error log> > >> On Dec 2, 2015, at 4:34 AM, Aaron D.

I faced a new problem in loading RDF data process. Following the tutorial, I created loadrdf folder and N-Triples file $RDF_DATA, when I complied and run the java code, it gave the error message like :”java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/web.rya/loadrdf/?format=N-Triples <http://localhost:8080/web.rya/loadrdf/?format=N-Triples>” my tomcat host server’s URL is localhost and port number is 8080 by default. >> >> Also another question is about bulk load RDF data.
